Co-occurrence of bacteria and viruses and serotype distribution of Streptococcus pneumoniae in the nasopharynx of Tanzanian children below 2 years of age following introduction of the PCV13. Front Public Health 2024; 12:1298222. [PMID: 38317802 PMCID: PMC10839969 DOI: 10.3389/fpubh.2024.1298222] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Accepted: 01/04/2024] [Indexed: 02/07/2024] Open
Abstract
Introduction Pneumococcal conjugate vaccines have reduced severe disease attributed to vaccine-type pneumococci in children. However, the effect is dependent on serotype distribution in the population and disease development may be influenced by co-occurrence of viral and bacterial pathogens in the nasopharynx. Methods Following introduction of the 13-valent pneumococcal conjugate vaccine (PCV13) in Tanzania we performed repeated cross-sectional surveys, including 775 children below 2 years of age attending primary healthcare centers. All children were sampled from nasopharynx and pneumococci were detected by single-target PCR. Pneumococcal serotypes/groups and presence of viruses and other bacteria were determined by two multiplex PCR assays. Results The prevalence of PCV13 vaccine-type pneumococci decreased by 50%, but residual vaccine-types were still detected in 21% of the children 2 years after PCV13 introduction. An increase in the non-vaccine-type 15 BC was observed. Pneumococci were often co-occurring with Haemophilus influenzae, and detection of rhino/enterovirus was associated with higher pneumococcal load. Discussion We conclude that presence of residual vaccine-type and emerging non-vaccine-type pneumococci in Tanzanian children demand continued pneumococcal surveillance. High co-occurrence of viral and bacterial pathogens may contribute to the disease burden and indicate the need of multiple public health interventions to improve child health in Tanzania.

Trend and factors associated with non-suppression of viral load among adolescents on ART in Tanzania: 2018-2021. FRONTIERS IN REPRODUCTIVE HEALTH 2024; 6:1309740. [PMID: 38292142 PMCID: PMC10823012 DOI: 10.3389/frph.2024.1309740] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2023] [Accepted: 01/02/2024] [Indexed: 02/01/2024] Open
Abstract
Background Tanzania is one of the countries with a high burden of HIV. It has an estimated 1.4 million people living with HIV in 2021. Adolescents living with HIV on antiretroviral therapy (ART) have worse treatment adherence, viral suppression, and mortality rates compared to adults. This study aim was to determine the trend of non-suppression among adolescents on ART in Tanzania from 2018 to 2021 and latest associated predictors. Methodology The study utilized data of adolescents (10-19 years) receiving ART in Tanzania mainland for the period of 2018-2021 from the National Care and Treatment Centers database. The primary outcome of interest was non-suppression of viral load, defined as a VL above 1,000 copies/ml. The study employed multivariable logistic regression models to identify factors associated with non-suppression of VL. STATA 15 statistical software was used to analyze the data. Results Records of 65,942 adolescents present in the CTC database Tanzania were analyzed. Approximately more than half were female 38,544 (58.5%). The proportion of non-suppression was 34.5%, 23.3%, 12.1%, and 9.7% for the years 2018-2021, respectively. After adjusting for other factors, adolescents with a history of poor adherence to ART in the last six months had higher odds of non-suppression (OR = 1.95, 95% CI = 1.64, 2.31). Adolescents on second or third line ART regimens were almost two times more likely to be non-suppressed compared to those on first-line regimens (OR = 2.85, 95% CI = 2.52, 3.23). Girls had lower odds of non-suppression compared to boys (OR = 0.91, 95% CI = 0.84, 0.98), and similarly, patients attending hospitals had lower odds compared to those attending dispensaries (OR = 0.79, 95% CI = 0.72, 0.87). Conclusion Being female, having good history of adherence over the last six months, and attending hospital level was significantly associated with lower levels of non-suppression, while being on second line ART or attending lower health facilities increased the odds of non-suppression. Efforts to enhance the quality and capacity of health services at lower-level facilities (dispensaries and health centers) should be prioritized, as well as promoting gender-sensitive approaches that take into account the unique needs and experiences of adolescent girls and boys are needed to improve VL suppression among this population.

Concentrations of respirable crystalline silica and radon among tanzanite mining communities in Mererani, Tanzania. Ann Work Expo Health 2024; 68:48-57. [PMID: 37824745 DOI: 10.1093/annweh/wxad062] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2022] [Accepted: 09/18/2023] [Indexed: 10/14/2023] Open
Abstract
BACKGROUND Globally, the number of small-scale miners (SSM) is estimated to be more than 25 million, but it supports the livelihoods of around 100 million individuals. In Tanzania, the number of SSM has increased from an estimated 150,000 in 1987 to ~1.5 million in 2017. The miners are at a high risk of occupational-related health challenges. The study aimed to assess the concentrations of respirable crystalline silica (RCS) and radon among the tanzanite mining communities in Simanjiro District, Tanzania. METHODS We carried out a cross-sectional study involving the Mererani mines in Tanzania. These are underground mines comprised of informally employed miners, i.e. SSM. Concentrations of RCS and radon gas were measured in 44 study units, i.e. 22 mining pits and within 22 houses in the general community, e.g. shops in the peri-mining community. A total of 132 respirable personal dust exposure samples (PDS), 3 from each of the study units were taken, but only 66 PDS from the mining pits were analysed, as this was the main interest of this study. Radon concentration was measured by continuous monitoring throughout the working shift (and overnight for residences) using AlphaGuard monitor. The medians and comparison to the reference values, OSHA USA PEL and WHO/IARC references, were done for RCS and radon, respectively, using SPSS Ver. 27.0.0). RESULTS The median time-weighted average (TWA) concentration of the RCS in the mining pits was 1.23 mg/m3. Of all 66 personal dust samples from the mining pits, 65 (98.5%) had concentrations of RCS above the Occupational Safety and Health Administration (OSHA) permissible exposure limit (PEL) of 0.05 mg/m3. Mining pits had a median radon concentration of 169.50 bq/m3, which is above the World Health Organization (WHO)/International Commission on Radiation Protection (ICRP) recommended reference of 100.00 bq/m3 but not above the upper reference of 300.00 bq/m3, while the community buildings had a median radon concentration of 88.00 bq/m3. Overall, 9 (20.5%) and 17 (38.6%) radon measurements were above 300.00 bq/m3 and between 100.00 and 300.00 bq/m3 references, respectively. Specifically, in the mining pits, 9 (40.9%) test results were above 300.00 bq/m3, while none of the test results in the community was above 300.00 bq/m3. CONCLUSION The tanzanite SSM in Mererani we highly exposed to RCS, which increases the risk of pulmonary diseases, including silicosis, tuberculosis, and pulmonary malignancies. Immediate action by OSHA Tanzania should be enforcement of wearing respirators by all miners throughout the working hours. Health education programmes to the SSM must be strengthened and OSHA Tanzania should adopt the 0.05 mg/m3 PEL, and enforce other occupational health and safety measures, including regular use of dust suppression mechanisms (water spray and wet drilling) and monitoring of RCS exposures among SSM. Monitoring of radon exposure both in the mining pits and community buildings should be conducted, and mitigation measures should be implemented in areas that exceed the reference level of 100.00 bq/m3.

Factors associated with offer and uptake of provider-initiated HIV testing and counselling among men attending healthcare facilities in Moshi Municipality, Northern Tanzania. PLoS One 2023; 18:e0291792. [PMID: 37729175 PMCID: PMC10511071 DOI: 10.1371/journal.pone.0291792] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2021] [Accepted: 09/06/2023] [Indexed: 09/22/2023] Open
Abstract
BACKGROUND HIV Testing and Counseling is a critical entry-point for HIV care, treatment and prevention. Tanzania adopted the WHO recommendations of Provider-Initiated HIV Testing and Counseling (PITC) in 2007 with the aim of increasing early HIV diagnosis and timely access to treatment and support services. However, approximately 55% of men are still unaware of their HIV status. This study aimed to determine the level of PITC uptake and factors associated with PITC availability and uptake among men attending healthcare facilities in Moshi Municipality, Northern Tanzania. METHOD A facility-based cross-sectional study was conducted in July 2019 in five selected healthcare facilities in Moshi Municipal, Kilimanjaro region. Exit interviews were conducted with men aged 18 years and above who attended for care in the selected facilities. Modified Poisson regression modelling with robust standard errors were used to determine factors independently associated with being offered and accepting the PITC offer. RESULTS A total of 562 men participated in this study. The median age of participants at enrollment was 37 (IQR: 26-59) years. Only 58% of participants reported to have been offered provider-initiated HIV counseling. Of these, 83% accepted the offer of HIV testing. Age between 35-59 years (aPR = 1.2; 95% Confidence Interval (CI): 1.0, 1.4; p = 0.033) and having primary education (aPR = 0.7; 95% CI: 0.6, 0.9; p = 0.010) were factors independently associated with being offered PITC. Age between 35-59 years (aPR = 0.8; 95% CI: 0.7, 0.9; p = 0.002); having been previously tested for HIV (aPR = 1.3; 95% CI: 1.1, 1.5; p = 0.011) and visiting a health facility twice or more in previous year (aPR = 1.3; 95% CI: 1.2, 1.5; p<0.001) were independently associated with uptake of HIV testing. CONCLUSION Despite high PITC uptake, about 2 in 5 men attending healthcare facilities in Moshi municipality were not offered the service. Providers should target men aged ≤ 34 years, with primary education, visiting facilities for the first time and who have never been tested for HIV.

A Qualitative Study on Barriers to COVID-19 Vaccine Uptake among Community Members in Tanzania. Vaccines (Basel) 2023; 11:1366. [PMID: 37631934 PMCID: PMC10458528 DOI: 10.3390/vaccines11081366] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 06/02/2023] [Accepted: 06/21/2023] [Indexed: 08/29/2023] Open
Abstract
The use of vaccines is one of the key tools in reversing the COVID-19 pandemic; however, various reports reported the low uptake of the vaccines. This study explored the barriers to the COVID-19 vaccine uptake among community members in Tanzania. A qualitative explorative study was conducted in December 2021 and April 2022 in eight regions of Tanzania. Focus group discussions (FGDs) and in-depth interviews (IDIs) were the methods of data collection. A total of 48 FGDs and 32 IDIs were conducted. Participants were aware of the COVID-19 disease and vaccines. The barriers to the COVID-19 vaccine non-uptake included receiving contradicting statements from top government leaders, vaccine preceded the education, myths towards vaccines, the presence of different types of vaccines, the process of getting the vaccine, the influence of social media and random people from the community, and vaccine conflicting religious beliefs. Despite being aware of the vaccine, the uptake of the COVID-19 vaccine is still low. Interventions that focus on increasing community knowledge about COVID-19 vaccines and addressing myths about the vaccines are needed.

Factors Associated with Modern Contraceptive Use Among Out of School Adolescent Girls in Majengo and Njoro Wards of Moshi Municipality, Tanzania. East Afr Health Res J 2023; 7:32-39. [PMID: 37529491 PMCID: PMC10388620 DOI: 10.24248/eahrj.v7i1.706] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Accepted: 05/30/2023] [Indexed: 08/03/2023] Open
Abstract
Background Low uptake of modern contraceptives among adolescents remains a serious public health concern with over 20 million adolescents in need of modern contraceptives are not using any. In Tanzania where the adolescent fertility rate is 112 per 1000, only 15.2% of adolescents are using modern contraceptives. Contraceptive use stands out to be one of the key interventions to reduce the burden of adolescent pregnancy which is high in the country at 22%. There is little information on factors associated with modern contraceptive use among out of school adolescents, who are at an increased risk of adolescent pregnancies. Objective To determine the prevalence and factors associated with modern contraceptive use among out of school adolescent girls in Moshi municipality, Kilimanjaro region. Methodology This was a population based cross-sectional study, conducted in Moshi municipality in Kilimanjaro region 2 wards; Majengo and Njoro. The wards were randomly selected out of the 21 wards in the region. Household survey was conducted in the wards and adolescents aged 10 to 19 years who were out of school and consented and or assented to participate in the study were recruited. Data was collected using Kobo Collect TM on an Android device. Data was analysed using SPSS version 20. To determine the factors associated with modern contraceptive use, crude and adjusted analysis using logistic regression analysis was done. Results A total of 298 out-of-school adolescents were enrolled, with a median age of 19 (IQR 17-19) years. The prevalence of ever use of modern contraceptives among 154 sexually active adolescents was 51%, and 35% were current users of the methods. Two of common methods ever used were; injectables (27.3%) and male condoms (3.2%) respectively. Factors independently associated with ever use of modern contraceptives were; being married or cohabiting (aOR: 5.7) and having 2 or more sexual partners in the past 12 months (aOR: 5.9). Conclusion Ever and current use of modern contraceptives among out-of-school adolescents were reported at 51% and 35% respectively. Respondent's marital status and number of sexual partners was associated with ever use of modern methods. Strengthening of adolescent-friendly SRH services outside facility setting is needed given very few are currently using a modern method. Further, through inter-sectoral collaboration interventions to keep adolescent girls at school should be strengthened.

Confidence in COVID-19 vaccine effectiveness and safety and its effect on vaccine uptake in Tanzania: A community-based cross-sectional study. Hum Vaccin Immunother 2023; 19:2191576. [PMID: 37017234 PMCID: PMC10088920 DOI: 10.1080/21645515.2023.2191576] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 04/06/2023] Open
Abstract
COVID-19 is a major public health threat associated with increased disease burden, mortality, and economic loss to countries and communities. Safe and efficacious COVID-19 vaccines are key in halting and reversing the pandemic. Low confidence in vaccines has been one of the factors leading to hesitancy. We aimed to assess the COVID-19 vaccine confidence (safety and effectiveness), associated factors, and its effects on vaccine uptake among general community members in Tanzania. This was a community-based cross-sectional survey conducted from December 2021 to April 2022 in six regions of Tanzania mainland and two regions in Zanzibar. Participants were interviewed using an electronic questionnaire. Multiple logistic regression models estimated odds ratios (ORs) and 95% confidence interval (CI) for factors associated with vaccine confidence. All analyses were performed using SPSS version 25.0. The study enrolled 3470 general Tanzanian community members; their mean age was 40.3 (standard deviation ±14.9) years, and 34% were males. The proportion of COVID-19 vaccine confidence was 54.6%. Geographical region, residence area, COVID-19 disease risk perception, and good knowledge of COVID-19 vaccines were significantly associated with COVID-19 vaccine confidence. Confidence in COVID-19 vaccines was associated with over three times higher odds of vaccine uptake. Confidence in COVID-19 vaccines was low in Tanzania. Innovative community engagement strategies and region-specific interventions are needed to improve comprehensive knowledge and address community perceptions and attitudes toward COVID-19 vaccines.

Knowledge on human papilloma virus and experience of getting positive results: a qualitative study among women in Kilimanjaro, Tanzania. BMC Womens Health 2023; 23:61. [PMID: 36774477 PMCID: PMC9921604 DOI: 10.1186/s12905-023-02192-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2021] [Accepted: 01/24/2023] [Indexed: 02/13/2023] Open
Abstract
BACKGROUND Human papilloma virus (HPV) is a sexually transmitted infection causing more than 80% of cervical cancers. WHO recommends using of sensitive screening methods like HPV-testing to timely prevent future morbidity and mortality from cervical cancer. Pilot studies have shown that HPV-testing is feasible and can be scaled in developing country like Tanzania. However, there is limited information on women understanding, reactions and psychological challenges following diagnosis of high risk HPV (HR-HPV). This study explored the knowledge of women on HPV and their experience after HPV positive results in Kilimanjaro, Tanzania. METHODS The study was part of a larger study that assessed incidence and persistence of HR-HPV among women aged 18 years and above in Kilimanjaro. This was a cross sectional study conducted in Moshi municipal council among women who had HR-HPV positive results at enrollment. In-depth interviews were conducted with 13 randomly selected women who were attending for follow-up after enrollment. Interviews were conducted at the health facility and Atlas.ti.8 was used to analyze the data using thematic framework analysis. RESULTS Women had knowledge on HPV infection but they had different reactions following receiving positive HPV results. Reaction toward the positive HPV results had two extremes; some women had psychological effect (hopeless, death sentence, having cancer, being shocked, failure to disclose and psychosexual effects) while others women explained positive results is good as they are identified earlier, will be followed up and it has made them plan to continue with cervical cancer screening in future. CONCLUSION Women had knowledge on HPV, but positive results lead to negative and positive experiences by women. Clinicians and programs need to develop interventions and good strategies to minimize the psychological and social burden of testing positive for HPV.

Abstract
OBJECTIVES To describe the characteristics and disability-related needs of children and adolescents with physical disabilities in the Kilimanjaro region, North-Eastern Tanzania. DESIGN A cross-sectional community survey was conducted from November 2020 to June 2021. Trained research assistants interviewed primary children's carers using a questionnaire based on the International Classification of Functioning, Disability and Health-Children and Youth Framework. Data were analysed using IBM SPSS Statistics V.27. The Pearson χ2 test was used to examine differences between age, gender and self-reported needs. The independent t-test assessed difference in needs according to age and gender. SETTING Kilimanjaro region, Tanzania. PARTICIPANTS Children and adolescents, aged 2-18 years, with physical disabilities (n=212). RESULTS Almost 40% had severe speech (n=84) and joint mobility (n=79) impairments, and more than half (n=124) had severe or complete difficulties walking. In aspects of self-care (caring for body parts, toileting, dressing, eating and drinking), most had severe and complete difficulties. Almost 70% (n=135) of households were located near health facilities without rehabilitation services. About one-quarter (n=51) had never received rehabilitation services. More than 90% (n=196) needed assistive devices, and therapeutic exercises (n=193). Over three-quarters needed nutritional supplements (n=162). CONCLUSION Children and adolescents with physical disabilities in North-Eastern Tanzania have impaired speech and joint mobility, and difficulties in communication, self-care and walking. Rehabilitation services essential for addressing these impairments and activity limitations are either scarce or inaccessible. Action is needed to facilitate urban and rural access to rehabilitation services in order to improve the well-being of children and adolescents with physical disabilities.

Abstract
Introduction Healthy dietary habits prevent childhood overweight and obesity and the risk of non-communicable diseases (NCDs) later in life. We examined dietary patterns and their association with adiposity among primary school children in northern Tanzania. Methods Dietary data was collected by 24-h recall and food frequency questionnaire (FFQ) for 1170 primary school children aged 9 – 11 years from 20 primary schools in the Kilimanjaro region. Factor analysis and FFQ data were used to identify dietary patterns. Children were categorized into terciles of their adherence to each dietary pattern. Multilevel logistic regression was used to evaluate the association of dietary pattern terciles with adiposity indicators: body mass index z–scores (BMI z scores), body fat percentage by bioelectrical impedance, triceps, subscapular skinfold thicknesses, and waist circumference. Results Fifteen percent of children had BMI Z > 1.0, indicating overweight or obesity. Two dietary patterns were identified by factor analysis: a healthy pattern characterized by frequent consumption of fruits and vegetables; and a mixed dietary pattern characterized by intake of fatty snacks, sweets and sugar snacks, sugary beverages, meat and alternatives, milk, and milk products. After adjusting for potential confounders, for both models: model 1 (age and sex), and model 2 (age, sex, school type, time spent walking to school, district [urban/ rural], availability of television and electronic gadgets at home and neighbourhood playground); we found no significant associations between dietary patterns and adiposity measures. Conclusion Dietary patterns were not associated with adiposity in Tanzanian primary school children, possibly because of limitations of the FFQ, which did not record information on portion sizes. Future research should focus on understanding the key foods / snacks consumed by school children, portion sizes and their long-term effects on adiposity in children. Supplementary Information The online version contains supplementary material available at 10.1186/s40795-022-00529-4.

Abstract
This study aimed to examine associations of dietary quality and diversity among reproductive-aged women with overweight and obesity. We conducted a cross-sectional study in the Health and Demographic Surveillance System of the Dar es Salaam Urban Cohort Study (DUCS) in Tanzania. A random sample of 1004 non-pregnant women was selected from the DUCS population database and interviewed about dietary information using the FFQ. Women were aged 30.2 (±8.1) years; 27.8% were overweight and 22.6% were obese. All 1004 women in the study consumed starchy staple foods. Of all the women studied, 10.5%, 1.7% and 3.8% consumed vitamin A rich dark green vegetables, nuts and seeds, and beans and peas, respectively. Compared with women in the lowest quintile of Prime Dietary Quality Score (PDQS), those who were in the highest quintile were significantly less likely to be overweight or obese (Adjusted Prevalence Ratio (APR) = 0.76, 95%CI: 0.62, 0.89) (F for trend = 0.029). Dietary diversity score (DDS) was not significantly associated with overweight and obesity. Risk factors included the highest consumption of animal foods (APR = 2.81, 95% CI: 1.51-3.51) and fast food (APR = 2.57, 95% CI: 1.24-4.34). Consumption of legumes and whole grains was associated with lower risk (APR = 0.59; 95% CI: 0.38-0.2). Dietary quality is an important predictor of overweight and obesity among women of reproductive age. Nutrition interventions may be warranted to support women of reproductive age to enter pregnancy with healthier weight to prevent adverse pregnancy outcomes and future risk of chronic diseases.

Adherence to Optimal Breastfeeding Practices Among HIV-Positive Mothers in Kilimanjaro, Tanzania. Patient Prefer Adherence 2022; 16:841-852. [PMID: 35387257 PMCID: PMC8977531 DOI: 10.2147/ppa.s343213] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2021] [Accepted: 03/04/2022] [Indexed: 12/04/2022] Open
Abstract
Purpose We sought to assess how HIV-positive mothers enrolled in the PMTCT program adhere to breastfeeding recommendations concerning early initiation of breastfeeding (EIBF), ie, within one hour of birth, pre-lacteal feeds, exclusive breastfeeding until six months (EBF), and continued breastfeeding to one year of age. This study was designed to assess the practices in response to changing recommendations for breastfeeding in HIV, which have differed drastically over the years. Patients and Methods We recruited 524 mother-child pairs from 37 PMTCT clinics across Kilimanjaro, Tanzania. The 5 clinics with the highest patient load in each of the 7 districts of Kilimanjaro were chosen, plus the zonal and municipal referral hospitals. The children were below two years of age and currently in the PMTCT program. We administered a questionnaire to assess the mother's practices in feeding the child. We used multiple logistic regression models to determine factors associated with EIBF, EBF, and continued breastfeeding. Results EIBF was achieved for 73.1% of babies. Cesarean delivery, low birth weight, and partner disclosure of HIV status were significant risk factors for not achieving EIBF. About 19% of children did not breastfeed exclusively. Of the 247 children ≥12 months old, 43.3% had stopped breastfeeding before 12 months. Counseling on ARV, having had >2 pregnancies while HIV-positive and EBF were associated with breastfeeding until 12 months old. Using ART for more than two years decreased the odds of EBF and continued breastfeeding to 12 months of age. Conclusion Adherence to breastfeeding recommendations for HIV-positive women is suboptimal, particularly in aspects of recent changes in recommendations such as continuing breastfeeding for one year. There is a missed opportunity for interventions such as counseling, which has shown to favor adherence. Health education and counseling are needed for providers and mothers to keep them abreast with the frequently changing recommendations.

[PMID: 35036846 PMCID: PMC8751482 DOI: 10.24248/eahrj.v5i2.671] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2020] [Accepted: 11/04/2021] [Indexed: 11/20/2022] Open
Abstract
INTRODUCTION Post Abortion Care (PAC) encompassing family planning counselling and contraception provision is a key strategy to reducing maternal morbidity and mortality especially in countries with restrictive abortion laws. Various factors affect the uptake of PAC modern family Planning (FP) in different settings. This study aimed at determining the prevalence, assessment of factors and barriers to PAC modern FP uptake in Hai district, Northern Tanzania. METHODS A mixed-methods study was conducted using an explanatory sequential design. Exit interviews using questionnaires was conducted among 189 women. In-depth interviews were conducted with 26 healthcare providers (HCPs) and 28 women who received PAC in Hai district hospital, Machame hospital and Moshi Specialists health centre in Hai district. Quantitative data was analysed using a Statistical Package for Social Science (IMB SPSS Statistics for Windows version 20.0 (SPSS Inc., Chicago, Ill., USA)). Bivariate and multivariable analyses were applied to estimate the predictors of uptake of PAC modern FP. Thematic content analysis was employed to explore barriers to uptake of post-abortion modern family planning. RESULTS The prevalence of uptake of modern family planning following PAC was 59/189(31.2%). 56% of the 189 women who received PAC did not receive counselling services on family planning. Marital status and partner's support were predictors of PAC modern family planning uptake (p=.007 vs. p= <.05, respectively).Misinformation and misconception about modern contraceptives, lack of knowledge and fear of side effects were reported to be the major barriers to uptake of post-abortion family planning. Most women reported to have not received comprehensive family planning information from the HCPs. On the other hand, HCPs perceived their poor counselling skills as the barrier to post-abortion family planning uptake. This study observed poor coordination of PAC services within each visited facility and this was linked to women leaving the facility without family planning counselling and/or contraceptives provision. CONCLUSION Suboptimal modern family planning counselling during PAC contributes to the low uptake of contraceptives methods in this setting. Strategies are needed to improve PAC modern family planning services uptake. Strategies such as; provision of counselling skills to HCPs with comprehensive information targeting local contextual misconception and promoting PAC provision as a one-stop service.

Risky sexual behaviours among young adults attending Higher Learning Institutions in Mbeya, Tanzania: implications for STIs and HIV preventive programs. AAS Open Res 2021. [DOI: 10.12688/aasopenres.13123.2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/20/2022] Open
Abstract
Background High-risk sexual behaviors(HRSBs) among young adults are key risk for Sexually Transmitted Infections(STIs), HIV and unplanned pregnancies. WHO has identified the 15-24years age-group as high-risk for STIs. Students at Higher Learning Institutions(HLIs) may be at higher risk because they are free of immediate parental-supervision, are a transient migratory population, probably at peak-years of sexual activity. In Tanzania, information is limited on sexual and preventive behaviours among young adults in HLIs. We describe risky sexual behaviours and preventive practices among young adults attending HLIs in Mbeya-Tanzania. Methods We conducted a cross-sectional study from March2019 to January2020 among randomly selected students aged 18-24years enrolled in HLIs within Mbeya. Probability proportional to size was used to determine total student number from each HLI. We used a self-administered questionnaire to collect information on sexual health education, activity, behaviour and STI knowledge. Results Total of 504students were enrolled with mean age of 21.5(SD 1.74)years. Total of 446(88.5%) students reported ever having had sex. Mean-age at first sex was 18.4years and 9.9% reported sexual debut <15years. A higher proportion of male students(57%) reported sexual debut with non-steady partners than females(37.9%). Lack of condom use at sexual debut was reported by 52% of the participants. Consistent condom use during past 4-weeks was reported at 33% and 16.5% among males and females, respectively. About 1 in 10 students reported forced sex by someone they were dating. Sex under the influence of alcohol was reported by 24% of the students. Nearly 8 in 10 (78.7%) students have heard of STIs, but only 16% were aware STIs can be asymptomatic. Conclusion STI prevention programs need to recognize young adults in HLIs as at-risk population; and advocate targeted messages to minimize risk to acquiring STIs, counseling and support for those experiencing sexual violence, promote condom use and safer-sex negotiation skills.

Time to cessation of exclusive breastfeeding and associated factors among women with children aged 6-24 months in Kilimanjaro region, northern Tanzania: A community-based cross-sectional study. PLoS One 2021; 16:e0259041. [PMID: 34710150 PMCID: PMC8553062 DOI: 10.1371/journal.pone.0259041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2021] [Accepted: 10/11/2021] [Indexed: 11/25/2022] Open
Abstract
Background Exclusive breastfeeding (EBF) up to six months is sub-optimal globally. Tanzania has surpassed the World Health Assembly (WHA) target of increasing the rate of exclusive breastfeeding among children below six months to at least 50% by the year 2025 the median age of cessation of EBF is only three months. Objective To determine the time to cessation of exclusive breastfeeding and its associated factors among women with children aged 6–24 months in Kilimanjaro region, Northern Tanzania. Methods This was a secondary analysis of data from a community-based cross-sectional study conducted between April 2016 and April 2017 in Kilimanjaro region, northern Tanzania. In the parent study, a multistage sampling technique was used to select study participants and interviewed using a questionnaire. Data for 1291 mother-child pairs were analyzed using STATA version 15. Kaplan-Meier method with the log-rank test estimated and compared the survivor functions across covariate levels. Cox regression proportional hazards models estimated the hazard ratios (HR) and their 95% confidence intervals (CI) for factors associated with time to cessation of exclusive breastfeeding. Results The prevalence of cessation of exclusive breastfeeding before six months was 68.7%, with a median age of cessation of four months (95% CI: 3, 4). In comparison to women living in Siha district, women living in Moshi Municipal (HR = 1.61; 95% CI = 1.24, 2.09), Same (HR = 1.32; 95% CI = 1.06, 1.65) and Mwanga (HR = 1.53; 95% CI = 1.20, 1.96) districts, had higher hazards of cessation of exclusive breastfeeding before six months. Women who received breastfeeding counselling at antenatal care had a lower hazard to cease EBF (HR = 0.76, 95% CI 0.65, 087) compared to those who did not receive breastfeeding counselling. Conclusion The median age of cessation of EBF is unsatisfactory but at least higher (four months) than the national level estimate of three months. District specific interventions and breastfeeding counselling at antenatal care are essential for improving time to cessation of exclusive breastfeeding. Promotion of adequate ANC visits remains one of the critical interventions to improve BF practices and other reproductive health outcomes.

Where and how do young people like to get their sexual and reproductive health (SRH) information? Experiences from students in higher learning institutions in Mbeya, Tanzania: a cross-sectional study. BMC Public Health 2021; 21:1683. [PMID: 34530796 PMCID: PMC8444543 DOI: 10.1186/s12889-021-11728-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Accepted: 09/03/2021] [Indexed: 11/20/2022] Open
Abstract
Background Sexual and reproductive health (SRH) among young adults in low- and middle-income countries (LMIC) is still a major public health challenge. Early school-based sexuality education programs and sexual health information sharing between teachers, parents and young people have been considered protective against the sexual health risks to which young people are exposed. There is, however, limited information on the preferred choices of “where”, “how” and “from whom” young people would like to receive SRH information. We aimed to describe the experience and preferences of young people regarding their SRH education and learning and in particular communication with their parents/guardians. Methods We conducted a cross-sectional study among randomly selected students aged 18-24y attending Higher Learning Institutions (HLIs) in Mbeya, Tanzania. We used a self-administered questionnaire to collect information on SRH education received, ability to discuss SRH matters with a parent/guardian and SRH information gaps encountered during their early sexual experience. Results We enrolled 504 students from 5 HLIs, of whom 446 (88.5%) reported to be sexually active, with mean age at sexual debut of 18.4y (SD 2.2). About 61% (307/504) of the participants found it difficult to discuss or did not discuss SRH matters with their parent/guardian while growing up. Learning about SRH matters was reported from peers (30.2%) and teacher-led school curriculum (22.7%). There was a strong gender-biased preference on SRH matters’ discussions, female and male participants preferred discussions with adults of their respective sex. Peers (18.2%), media (16.2%) and schools (14.2%) were described as the preferred sources of SRH information. On recalling their first sexual experience, sexually-initiated participants felt they needed to know more about sexual feelings, emotions and relationships (28.8%), safer sex (13.5%), how to be able to say ‘No’ (10.7%) and how to use a condom correctly (10.2%). Conclusion Young people have a gender preference when it comes to learning about SRH matters from their parents; however, such conversations seldom occur. Community health education should focus on building skills of parents on parent-child communication on SRH matters so as to empower them to confidently initiate and convey accurate SRH information. Comprehensive SRH education and skills building need to be strengthened in the current school SRH curriculum in order to meet the demand and needs of students and increase the competence of teachers.

Impact of Isoniazid Preventive Therapy on Tuberculosis incidence among people living with HIV: A secondary data analysis using Inverse Probability Weighting of individuals attending HIV care and treatment clinics in Tanzania. PLoS One 2021; 16:e0254082. [PMID: 34255776 PMCID: PMC8277069 DOI: 10.1371/journal.pone.0254082] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2020] [Accepted: 06/21/2021] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND Information on how well Isoniazid Preventive Therapy (IPT) works on reducing TB incidence among people living with HIV (PLHIV) in routine settings using robust statistical methods to establish causality in observational studies is scarce. OBJECTIVES To evaluate the effectiveness of IPT in routine clinical settings by comparing TB incidence between IPT and non-IPT groups. METHODS We used data from PLHIV enrolled in 315 HIV care and treatment clinic from January 2012 to December 2016. We used Inverse Probability of Treatment Weighting to adjust for the probability of receiving IPT; balancing the baseline covariates between IPT and non-IPT groups. The effectiveness of IPT on TB incidence was estimated using Cox regression using the weighted sample. RESULTS Of 171,743 PLHIV enrolled in the clinics over the five years, 10,326 (6.01%) were excluded leaving 161,417 available for the analysis. Of the 24,800 who received IPT, 1.00% developed TB disease whereas of the 136,617 who never received IPT 6,085 (4.98%) developed TB disease. In 278,545.90 person-years of follow up, a total 7,052 new TB cases were diagnosed. Using the weighted sample, the overall TB incidence was 11.57 (95% CI: 11.09-12.07) per 1,000 person-years. The TB incidence among PLHIV who received IPT was 10.49 (95% CI: 9.11-12.15) per 1,000 person-years and 12.00 (95% CI: 11.69-12.33) per 1,000 person-years in those who never received IPT. After adjusting for other covariates there was 52% lower risk of developing TB disease among those who received IPT compared to those who never received IPT: aHR = 0.48 (95% CI: 0.40-0.58, P<0.001). CONCLUSION IPT reduced TB incidence by 52% in PLHIV attending routine CTC in Tanzania. IPTW adjusted the groups for imbalances in the covariates associated with receiving IPT to achieve comparable groups of IPT and non-IPT. This study has added evidence on the effectiveness of IPT in routine clinical settings and on the use of IPTW to determine impact of interventions in observational studies.

Tanzanian primary healthcare workers' experiences of antibiotic prescription and understanding of antibiotic resistance in common childhood infections: a qualitative phenomenographic study. Antimicrob Resist Infect Control 2021; 10:94. [PMID: 34176486 PMCID: PMC8237496 DOI: 10.1186/s13756-021-00952-5] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2021] [Accepted: 05/17/2021] [Indexed: 11/30/2022] Open
Abstract
Background Antibiotic resistance is a threat to global child health. Primary healthcare workers play a key role in antibiotic stewardship in the community, but few studies in low-income countries have described their experiences of initiating antibiotic treatment in children. Thus, the present study aimed to describe primary healthcare workers’ experiences of antibiotic prescription for children under 5 years of age and their conceptions of antibiotic resistance in Northern Tanzania. Methods A qualitative study involving individual in-depth interviews with 20 prescribing primary healthcare workers in Moshi urban and rural districts, Northern Tanzania, was performed in 2019. Interviews were transcribed verbatim, translated from Kiswahili into English and analysed according to the phenomenographic approach. Findings Four conceptual themes emerged during the analysis; conceptions in relation to the prescriber, the mother and child, other healthcare actors and in relation to outcome. The healthcare workers relied mainly on clinical examination and medical history provided by the mother to determine the need for antibiotics. Confidence in giving advice concerning non-antibiotic treatment varied among the participants and expectations of antibiotic treatment were perceived to be common among the mothers. Antibiotic resistance was mainly perceived as a problem for the individual patient who was misusing the antibiotics. Conclusions To increase rational antibiotic prescription, an awareness needs to be raised among Tanzanian primary healthcare workers of the threat of antibiotic resistance, not only to a few individuals, but to public health. Guidelines on childhood illnesses should be updated with advice concerning symptomatic treatment when antibiotics are not necessary, to support rational prescribing practices and promote trust in the clinician and mother relationship.

Do Women Enrolled in PMTCT Understand the Recommendations: A Case Study from Kilimanjaro. Patient Prefer Adherence 2021; 15:1301-1309. [PMID: 34163147 PMCID: PMC8216065 DOI: 10.2147/ppa.s307847] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Accepted: 04/21/2021] [Indexed: 11/23/2022] Open
Abstract
INTRODUCTION Prevention of mother-to-child transmission (PMTCT) remains a cornerstone of HIV prevention and control efforts. It is vital that the beneficiaries of PMTCT programs understand PMTCT recommendations, especially since their adherence to recommendations is key to successful PMTCT. There have been several major changes in PMTCT recommendations, and many women have encountered different recommendations. It is plausible that confusion has arisen as to what is currently recommended for successful PMTCT. This confusion can affect adherence to recommendations and hinder PMTCT efforts. However, little is known about how women enrolled in PMTCT understand the recommendations in the context of these frequent changes. AIM In this paper, we present our findings regarding how HIV-positive women enrolled in PMTCT in Kilimanjaro understand PMTCT recommendations pertinent to them. METHODS From August 2019 to April 2020, we surveyed 521 mothers enrolled in PMTCT in seven districts in the Kilimanjaro region, Northern Tanzania. A pretested questionnaire was administered to consenting mothers. The questionnaire collected information on mothers' demographic characteristics, previous encounters with PMTCT, and knowledge of various PMTCT program elements, including medication duration, breastfeeding recommendations and infant HIV testing schedule. A logistic regression model was used to determine factors associated with good PMTCT knowledge among mothers. RESULTS A total of 521 women were enrolled, the median score for the 19 items used to assess knowledge was 57.9%, and 64.9% scored above the median. Counselling on ART (OR=2.17, 95% CI 1.08-4.36) and counselling on breastfeeding during the ANC visits (OR=2.38, 95% CI 1.38-4.11) were the only factors that we found to be significantly associated with higher odds of good knowledge of PMTCT. CONCLUSION Even amongst mothers enrolled in PMTCT, poor understanding regarding key PMTCT recommendations prevails. There is a need to reassess the training modalities and look at ways to reinforce PMTCT messages to mothers.

Prevalence and risk factors for diabetes mellitus among tuberculosis patients in Moshi Municipal Council, Kilimanjaro Tanzania. East Afr Health Res J 2021; 5:69-74. [PMID: 34308247 PMCID: PMC8291211 DOI: 10.24248/eahrj.v5i1.653] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2020] [Accepted: 05/20/2021] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND Diabetes Mellitus (DM) is a worldwide public health problem and its prevalence has been rising rapidly in low and middle income countries (LMICs) including Tanzania. According to WHO report 2015, DM is ranked number six as a leading cause of death worldwide. Strong evidence suggests that DM may be associated with Tuberculosis (TB) and could affect TB treatment outcomes. Tanzania is among the 22 countries that have a high burden of TB and currently facing increased epidemic of DM. The increasing diabetes prevalence may be a threat to TB control and counteract strategies to end TB by 2030 as proposed by WHO. OBJECTIVE To determine proportion of TB patients who are co-infected with DM in Moshi municipal council, Kilimanjaro Tanzania. METHODOLOGY This study was a hospital based cross-sectional study conducted in April to July 2018 at 4 health facilities; Mawenzi Regional Referral hospital, St. Joseph District Designated hospital, Pasua Health center and Majengo Health centre in Moshi municipal. The study included adults aged 18 years and above attending either of the 4 health facilities for TB care. The study included newly diagnosed and those who were on TB treatment. Interviews were conducted followed by blood glucose testing. Data was entered and analysed using SPSS. RESULTS A total of 153 TB patients were enrolled, their mean age was 42.5 (±14.75) years and 46 (30.1%) were females. The prevalence of DM among TB patients in this study was 9.2%. Factors associated with TB-DM comorbidity were: age (OR 4.43, 95% CI: 1.18-16.55), HIV status (OR 3.88, 95% CI: 1.06-14.11), and family history of DM (OR 6.50, 95% CI 0.67-25.56). CONCLUSION One in ten patients with TB had confirmed DM. There is a need for future studies to assess if DM influences TB treatment and outcomes in this setting.

Description and comparison of physical activity from self-reports and accelerometry among primary school children in Kilimanjaro, Tanzania: a pilot study. AAS Open Res 2021; 3:40. [PMID: 34056542 PMCID: PMC8132476 DOI: 10.12688/aasopenres.13118.4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/11/2021] [Indexed: 11/29/2022] Open
Abstract
Background: Self-reports are commonly used to assess physical activity in children. Existing self-reports for physical activity have not been validated for primary school children in Tanzania. To understand if primary school children can accurately report their physical activity, we examined the validity of self-reported physical activity against accelerometer measured physical activity. Methods: A community-based cross-sectional study was conducted from May to July 2018. We conveniently selected four primary schools in Moshi municipal and Moshi rural districts in Kilimanjaro, Tanzania. From these districts, 51 children aged 9 - 11 years were randomly selected. A self-reported questionnaire was used to collect physical activity-related variables. Children wore accelerometers for seven consecutive days to capture physical activity movements. Spearman's rank test and Bland Altman plots were used for assessing validity and agreement between self-reports and accelerometer moderate to vigorous physical activity (MVPA). Results: The study participants' mean age was 10 (SD=0.8) years, and 32 (63%) were girls. A significant positive correlation was found between self-reports and accelerometer MVPA (rho=0.36, p=0.009). The mean total of weekday minutes in MVPA from accelerometers was higher than from self-reports, 408 (SD = 66) versus 261 (SD = 179). Conclusions: This study found a significant positive correlation between self-reports and accelerometers. Self-reports are prone to errors due to recall bias, which interferes with their validity. More research is needed to develop better self-reported measures with specific activities that children can easily remember. Also, researchers should carefully consider the inherent limitations in the validity of self-reports.

Abstract
INTRODUCTION Childhood undernutrition is a major public health problem especially in low and middle-income countries (LMIC). The prevalence of early introduction of complementary feeding, low meal frequency, and low dietary diversity are frequent in LMICs. The effect of inappropriate complementary feeding practices on the nutritional status of children is not well documented in East African countries including Tanzania. Therefore, this study aimed at determining the effect of inappropriate complementary feeding practices on the nutritional status of children aged 6-24 months in urban Moshi, Tanzania. METHODOLOGY A retrospective cohort study was done using the Pasua and Majengo cohorts of mother-child pairs in urban Moshi who were enrolled from 2002 to 2017. About 3355 mother-child pairs were included in the analysis. Appropriate complementary feeding practices were assessed using WHO IYFP indicators such as age at introduction of solid, semi-solid, or soft foods, minimum dietary diversity, and minimum meal frequency. Nutritional status (stunting, wasting, and underweight) was determined. Multilevel modeling was applied to obtain the effect of inappropriate complementary feeding practices on the nutritional status of children and to account for the clustering effect of mothers and children and the correlation of repeated measures within each child. RESULTS Majority of the children (91.2%) were given soft/semi-solid/solid foods before six months of age, 40.3percent had low meal frequency, and 74percent had low dietary diversity. Early introduction of complementary food at age 0-1 month was statistically significantly associated with higher risks of wasting and underweight (ARR 2.9, 95%CI 1.3-6.3; and ARR 2.6, 95% CI 1.3-5.1 respectively). Children with low minimum meal frequency had higher risks of stunting, wasting, and underweight (ARR 2.9, 95%CI 2.3-3.6; ARR 1.9, 95%CI 1.5-2.5 and ARR 1.9, 95%CI 1.5-2.4 respectively). Children with low minimum dietary diversity were more likely to be stunted than is the case with their peers who received the minimum dietary diversity (ARR 1.3, 95% CI 1.01-1.6). CONCLUSION There were a high proportion of children, which were fed inappropriately; Inappropriate complementary feeding practices predisposed children to undernutrition. Our study supports the introduction of complementary feeding, providing minimum dietary diversity, and minimum feeding frequency at six months of age as important in improving the nutritional status of the children.

Abstract
Background Postpartum contraceptive discontinuation refers to cessation of use following initiation after delivery within 1 year postpartum. Discontinuation of use has been associated with an increased unmet need for family planning that leads to high numbers of unwanted pregnancies, unsafe abortion or mistimed births. There is scant information about contraceptive discontinuation and its predictors among postpartum women in Tanzania. This study aimed to determine predictors of contraception discontinuation at 3, 6, 12 months postpartum among women of reproductive age in Arusha city and Meru district, Tanzania. Methods This was an analytical cross-sectional study which was conducted in two district of Arusha region (Arusha city and Meru district respectively). A multistage sampling technique was used to select 13 streets of the 3 wards in Arusha City and 2 wards in Meru District. A total of 474 women of reproductive age (WRAs) aged 16–44 years residing in the study areas were included in this analysis. Data analysis was performed using STATA version 15. Odds ratios (ORs) with 95% confidence interval (CI) for the factors associated with contraceptives discontinuation (at 3, 6 and 12 moths) were estimated in a multivariable logistic regression model. Results Overall, discontinuation rate for all methods at 3, 6, and 12 months postpartum was 11, 19 and 29% respectively. It was higher at 12 months for Lactational amenorrhea, male condoms and injectables (76, 50.5 and 36%, respectively). Women aged 40–44 years had lower odds of contraceptive discontinuation at 3 months as compare to those aged 16 to 19 years. Implants and pills users had also lower odds of contraceptive discontinuation compared to injectable users at 3, 6 and 12 months respectively. Conclusion Lactational amenorrhea, male condoms and injectables users had the highest rates of discontinuation. Women’s age and type of method discontinued were independently associated with postpartum contraceptive discontinuation. Addressing barriers to continue contraceptive use amongst younger women and knowledge on method attributes, including possible side-effects and how to manage complications is warranted.

Results: The study participants' mean age was 10 (SD=0.8) years, and 32 (63%) were girls. A significant positive correlation was found between self-reports and accelerometer MVPA (rho=0.36, p=0.009). The mean total of weekday minutes in MVPA from accelerometers was higher than from self-reports, 408 (SD = 66) versus 261 (SD = 179). Conclusions: This study found a significant positive correlation between self-reports and accelerometers. Self-reports are prone to errors due to recall bias, which interferes with their validity. More research is needed to develop better self-reported measures with specific activities that children can easily remember. Also, researchers should carefully consider the inherent limitations in the validity of self-reports.

Prevalence and correlates of overweight and obesity among primary school children in Kilimanjaro, Tanzania. PLoS One 2021; 16:e0249595. [PMID: 33886578 PMCID: PMC8061999 DOI: 10.1371/journal.pone.0249595] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Accepted: 03/20/2021] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND Prevalence of childhood overweight and obesity in low- and middle-income countries is on the rise. We focused on multiple factors which could influence body mass index. METHODS A cross sectional school-based study was conducted in Moshi, Tanzania. Primary school children aged 9-11 years were recruited from 20 schools through a multistage sampling technique. Questionnaires were used to collect information on physical activity and diet by food frequency questionnaire. Height and weight measurements were taken and body mass index z scores for age and sex (BMIZ) calculated using the WHO AnthroPlus. Children were considered thin if BMIZ was <-2 standard deviations and overweight or obese if BMIZ was >1 SD. Information on school policies and environment was obtained from headteachers. Correlates of overweight and obesity were examined using a multinomial multilevel logistic regression. RESULTS A total of 1170 primary school children, of whom 636 (54%) were girls, were recruited from 20 schools. The prevalence of overweight and obesity was 15% overall (overweight 9% and obesity 6%) and most prevalent in urban areas (23%) and in private schools (24%). Moreover, thinness was found to be (10%) overall, most prevalent in rural areas (13%) and in government schools (14%). At school level, residing in urban (adjusted relative risk ratio [aRRR] 3.76; 95% confidence interval [CI] 2.49,5.68) and being in private school (aRRR 4.08; 95% CI 2.66,6.25) were associated with a higher risk of overweight and obesity while availability of playgrounds in schools (aRRR 0.68; 95% CI 0.47, 0.97) was associated with a lower risk of overweight and obesity. At home level, availability of sugary drinks (aRRR 1.52; 95% CI 1.01,2.28) was associated with a higher risk of overweight and obesity. CONCLUSION Overweight and obesity are common in private schools and in urban settings. Efforts should be taken to ensure availability of playgrounds in schools and encouraging children to engage in physical activities.

Initiation of postpartum modern contraceptive methods: Evidence from Tanzania demographic and health survey. PLoS One 2021; 16:e0249017. [PMID: 33765100 PMCID: PMC7993875 DOI: 10.1371/journal.pone.0249017] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2020] [Accepted: 03/10/2021] [Indexed: 11/19/2022] Open
Abstract
Background Postpartum contraceptive use is vital to improve maternal and child survival. It helps to have optimal child spacing, prevent unplanned pregnancies and associated adverse birth outcomes. However, postpartum contraceptive use in Tanzania remains low. Short median interval for resumption to sex after birth among African women has been associated with adverse maternal and child health wellbeing. This study aimed to assess optimal time to contraceptive use and predictors of time to contraceptive use after birth among women of reproductive age in Tanzania. Methods A cross section study using the TDHS 2015–16 data was used. A total of 3775 postpartum women were analyzed. Information on pregnancy, births and contraceptive use were recorded over the previous 5 years with the focus on most recent birth from the contraceptive calendar. Data analysis was performed using Stata 14.0. Analysis accounted for complex survey design. Time to modern contraceptive use after birth was computed using Kaplan Meier estimate. Adjusted time ratios with 95% CI were estimated using Weibull accelerated failure time models. Results A total weighted sample of 3775 women was analyzed. The median time to contraceptive use after birth was 7(IQR: 4–13) months, while for resumption to sex afterbirth was 2(IQR: 1–5) months. Factors such as never been married (TR: 1.63; 95%CI: 1.26–2.11) and breastfeeding (TR: 5.50; 95%CI: 4.12–7.35) were associated with longer time to postpartum contraceptive use. Belonging to richest wealth quintile (TR: 0.73; 95%CI: 0.54–0.99) and adopting long acting methods (TR: 0.70; 95%CI: 0.60–0.82) increased women’s likelihood of having shorter time to postpartum contraceptive use. Conclusion There was a time lag of five months from resumption of sex and initiation of postpartum contraception use. The interceptive measures to facilitate timely availing methods of women’s choice and promotion of utilization of maternal health care services may reduce delays in postpartum contraceptive use.

The association between human papillomavirus and cervical high-grade cytology among HIV-positive and HIV-negative Tanzanian women: A cross-sectional study. Acta Obstet Gynecol Scand 2021; 100:775-785. [PMID: 33512002 DOI: 10.1111/aogs.14102] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2020] [Revised: 12/19/2020] [Accepted: 01/11/2021] [Indexed: 11/30/2022]
Abstract
INTRODUCTION Human papillomavirus (HPV) is the causative agent of precancerous lesions and cervical cancer, cervical cancer being the leading cause of deaths in Tanzanian women. Early detection and treatment of precancerous lesions are important in the prevention of cervical cancer cases. MATERIAL AND METHODS We conducted a cross-sectional study among 3390 Tanzanian women aged 25-60 years. Information on lifestyle habits was collected, and women underwent gynecological examination with collection of cervical cells for conventional cytological and HPV testing. Blood samples were tested for HIV. The association between cervical high-grade cytology (HGC) and potential risk factors was examined using multivariable logistic regression adjusting for age and high-risk HPV (HR-HPV). RESULTS The prevalence of HGC was 3.6% and of low-grade cytology was 8.3%. In women who were both HR-HPV-positive and HIV-positive, the prevalence of HGC was 28.3%. It increased by age and was 47% among women aged 50-60 years. Women, who had their sexual debut at age 9-15 years and 16-18 years, respectively, had 2.5 and 2.4 times increased odds of HGC compared with women whose sexual debut was at age 21 years and older. HIV-positive women had increased odds of HGC in comparison with HIV-negative women after adjustment for age (odds ratio [OR] 2.95, 95% CI 1.92-4.54). HR-HPV-positive women had nearly 100-fold increased odds of HGC compared with HR-HPV-negative women (OR 96.6, 95% CI 48.0-194), and this estimate was higher among HIV-positive women (OR 152.2, 95% CI 36.1-642.0). CONCLUSIONS Increasing age, early age at first intercourse, HR-HPV, and HIV infections were associated with a substantially increased risk of HGC.

Inequalities in stunting among under-five children in Tanzania: decomposing the concentration indexes using demographic health surveys from 2004/5 to 2015/6. Int J Equity Health 2021; 20:46. [PMID: 33485344 PMCID: PMC7824937 DOI: 10.1186/s12939-021-01389-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2020] [Accepted: 01/18/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Child stunting is a global health concern. Stunting leads to several consequences on child survival, growth, and development. The absolute level of stunting has been decreasing in Tanzania from from 50% in 1991/92 to 34% in 2016 although the prevalence is still high (34%)Stunting varyies across socioeconomic determinants with a larger burden among the socioeconomic disadvantaged group. The reduction of inequalities in stunting is very crucial as we aim to reduce stunting to 28% by 2021 and hence attain zero malnutrition by 2030 under Sustainable Development Goal 2.2.This study aimed at determining the trend, contributing factors and changes of inequalities in stunting among children aged 3-59 months from 2004 to 2016. METHODS Data were drawn from the Tanzania Demographic and Health Surveys. The concentration index (CIX) was used to quantify the magnitude of inequalities in stunting. The pooled Poisson regression model was used to determine the factors for stunting, decision criterion for significant determinants was at 5% level of significance. The CIX was decomposed using the Wagstaff and Watanabe decomposition methods., the percentage contribution of each factor to the toal concentration index was used to rank the factors for socioeconomic inequalities in stutning. RESULTS Inequalities in stunting were significantly concentrated among the poor; evidenced by CIX = - 0.019 (p < 0.001) in 2004, - 0.018 (p < 0.001) in 2010 and - 0.0096 (p < 0.001) in 2015. There was insignificant decline in inequalities in stunting; the difference in CIX from 2004 to 2010 was 0.0015 (p = 0.7658), from 2010 to 2015/6 was - 0.0081 (p = 0.1145). The overall change in CIX from 2004 to 2015/6 was 0.00965 (p = 0.0538). Disparities in the distribution of wealth index (mean contribution > 84.7%) and maternal years of schooling (mean contribution > 22.4%) had positive impacts on the levels of inequalities in stunting for all surveyed years. Rural-urban differences reduced inequalities in stunting although the contribution changed over time. CONCLUSION Inequalities in stunting declined, differentials in wealth index and maternal education had increased contribution to the levels of inequalities in stunting. Reducing stunting among the disadvantaged groups requires initiatives which should be embarked on the distribution of social services including maternal and reproductive education among women of reproductive age, water and health infrastructures in remote areas.

Description and comparison of physical activity from self-reports and accelerometry among primary school children in Kilimanjaro, Tanzania: a pilot study. AAS Open Res 2021; 3:40. [PMID: 34056542 PMCID: PMC8132476 DOI: 10.12688/aasopenres.13118.2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 01/11/2021] [Indexed: 04/03/2024] Open
Abstract
Background: Self-reports are commonly used to assess physical activity in children. Existing self-reports for physical activity have not been validated for use among primary school children in, Tanzania. In order to understand if primary school children can accurately report their physical activity, we examined the validity of self-reported physical activity against accelerometer measured physical activity. Methods: A community based cross-sectional study was conducted from May to July, 2018. Four primary schools were conveniently selected in Moshi municipal and Moshi rural districts in Kilimanjaro, Tanzania and from these 51 children aged 9 - 11 years were randomly selected. Self-reported questionnaire was used to collect physical activity related variables. In addition, children wore accelerometers for seven consecutive days to capture physical activity movements. Spearman's rank test and Bland Altman plots were used for assessing validity and agreement between self-reports and accelerometer moderate to vigorous physical activity (MVPA). Results: The mean age of the study participants was 10 (SD=0.8) years and 32 (63%) were girls. A positive significant correlation was found between self-reports and accelerometer MVPA (rho=0.36, p=0.009). Accelerometer had higher mean MVPA 408 (SD = 66) compared to self-reports 261 (SD = 179). Children who reported walking to school had higher MVPA for both accelerometer and self- reports compared to children who use other means of transport to school, e.g. school buses (p < 0.001). Conclusions: This study found a positive significant correlation between self-reports and accelerometers. Self-reports are prone to errors due to recall bias, and this interferes their validity. More research is needed to develop better self-reported measures with specific activities which can easily be recalled by children. Also, researchers have to be aware of self-reports validity limitation.

Abstract
Background Erectile dysfunction (ED) has a negative impact on ones’ relationships with poor quality of life as inevitable result. The effects of ED maybe worse in developing countries setting like Tanzania because men’s sexual health has been forgotten. Men’s sexual and reproductive health needs are not in the national reproductive health strategic. This study aimed to determine the prevalence and factors associated with erectile dysfunction among adult men in Moshi municipality, northern Tanzania. Results The mean age of the 381 men was 39.6 (SD ±16.8) years. The overall prevalence of ED on this study was 29.7%. The severity of ED among study participants was; 13.4% (51), 9.7% (37), 3.7% (14), 2.9% (11) had mild, mild to moderate, moderate and severe erectile dysfunction respectively. Age 40–54 years (Adjusted OR 5.0, 95% CI 2.5–9.9), > 55 years (aOR 11.7, 95% CI 5.8–23.7) and hypertension (aOR 2.6, 95% CI 1.1–6.4) were independent predictors of ED respectively. Conclusion The prevalence of ED is high among men in Moshi municipal as 1 out of 3 men have ED. Age and hypertension were independent predictors of ED. These results point to the need of community awareness and education programs to raise awareness among men about existence of ED problem, its consequence and where they can get advice and care in this setting. Further, health providers taking care of hypertensive and men with DM should be equipped with knowledge and skills on early detection for ED and how to counsel and where to refer patients for help.

Abstract
Introduction The objective was to determine the prevalence, predictors and reasons for home delivery amongst women of childbearing age in Dodoma, Tanzania. Methods A cross-sectional study was conducted amongst women living in Dodoma Municipality. Data were collected using adapted questionnaires and analysed using SPPS version 23. A multivariable logistic regression model was used to assess the independent predictors of home delivery. Results A total of 425 women of childbearing age were enrolled in this study. The mean (± SD) age of the participants was 28.7 (±7.1) years. The prevalence of home delivery was 35.5% (n=150, 95% CI 30.9 – 40.2). Women with secondary school and above had 93% less odds of home delivery than women who had no education (AOR=0.0795% CI: 0.03–0.18). Women who lived in rural areas (AOR=3.49, 95% CI: 2.12–5.75), and women living more than 5km from health facilities (AOR=2.67, 95% CI: 1.65–4.37) had higher odds of home delivery. The main reasons for home delivery were transportation cost, and long distance to the nearest health facilities. Conclusion In this population, the prevalence of home delivery remained to be high. To address this more collaborative multisectoral effort like strengthening health education and strengthening maternity waiting homes are needed.

Abstract
Emergence of HIV drug resistance poses a serious risk of inactivity to all currently approved antiretroviral drugs. Profiles of HIV drug resistance mutations (HIVDRM) and virological failure (VF) are not extensively studied in Tanzania. This study aimed to determine HIVDRM and predictors of VF in HIV-infected individuals failing first-line HIV drugs in Moshi, Northern Tanzania. A case-control study was conducted at Kilimanjaro Christian Medical Centre, Mawenzi, Pasua and Majengo health facilities with HIV-care and treatment clinics from October, 2017 to August, 2018. Cases and controls were HIV-infected individuals with VF and viral suppression (VS) respectively. HIV-1 reverse transcriptase and protease genes were amplified and sequenced. Stanford University's HIV drug resistance database and REGA subtyping tool 3.0 determined HIVDRM and HIV-1 subtypes respectively. Odds ratios (OR) with 95% confidence interval (95% CI) investigated predictors of VF. P-value < 5% was considered statistically significant. A total of 124 participants were recruited, of whom 63 (50.8%) had VF, 61 (49.2%) had VS and 82 (66.1%) were females. Median [IQR] age and duration on ART were 45 [35-52] years and 72 [48-104] months respectively. Twenty-five out of 26 selected samples from cases were successfully sequenced. Twenty-four samples (96%) had at least one major mutation conferring resistance to HIV drugs, with non-nucleoside analogue reverse transcriptase inhibitor (NNRTI)-resistance associated mutations as the majority (92%). Frequent NNRTI-resistance associated mutations were K103N (n = 11), V106M (n = 5) and G190A (n = 5). Prevalent nucleoside analogue reverse transcriptase inhibitors-resistance associated mutations were M184V (n = 17), K70R (n = 7) and D67N (n = 6). Dual-class resistance was observed in 16 (64%) samples. Thirteen samples (52%) had at least one thymidine analogue-resistance associated mutation (TAM). Three samples (12%) had T69D mutation with at least 1 TAM. Two samples (8%) had at least one mutation associated with protease inhibitor resistance. Age [aOR = 0.94, 95% CI (0.90-0.97), p < 0.001] and occupation [aOR = 0.35, 95% CI (0.12-1.04), p = 0.059] associated with VF. In conclusion, HIV drug resistance is common among people failing antiretroviral therapy. Resistance testing will help to guide switching of HIV drugs.

Abstract
Background Early initiation of breastfeeding offers nutritional and immunological benefits to the newborn, which is critical for health and survival. Understanding factors associated with timely initiation of breastfeeding is crucial for healthcare providers and policy-makers. This study aimed to assess the prevalence and factors associated with early initiation of breastfeeding among mothers with children < 24 months of age in the Kilimanjaro region, Northern Tanzania. Methods This study utilized secondary data from a cross-sectional survey conducted in April 2016 and April 2017 in the Kilimanjaro region. A multistage sampling technique was used to select study participants and interviewed using a questionnaire. A total of 1644 women with children aged < 24 months were analyzed. Modified Poisson regression models were used to determine factors independently associated with early initiation of breastfeeding, within first hour of life. Results The prevalence of early initiation of breastfeeding in the Kilimanjaro region was 70%, ranging from 64% in Same to 80% in Siha districts. The prevalence of early initiation of breastfeeding was lower among women who initiated prelacteal feeding compared to their counterparts (prevalence ratio [PR] 0.42; 95% Confidence Interval [CI] 0.34, 0.53). Likewise, women living in Same and Hai district had lower prevalence of early initiation of breastfeeding compared to women in Rombo (PR 0.8; 95% CI 0.76, 0.93) and (PR 0.89, 95% CI 0.80, 0.98) respectively. Higher prevalence of early initiation of breastfeeding was found in women with primary education compared to those with secondary education (PR 1.09; 95% CI 1.003, 1.18), and among women with two children compared to one child (PR 1.14, 95% CI 1.03, 1.26). Conclusions Early initiation of breastfeeding practice was suboptimal in this study. To improve early initiation of breastfeeding, healthcare providers at reproductive and child health clinics and labour wards should discourage women from prelacteal feeding, give more support to women with one child and those with secondary level of education and above. Furthermore, a qualitative study is crucial to understand the reasons for low prevalence of early initiation of breastfeeding in Same and Hai districts.

Association between male involvement during antenatal care and use of maternal health services in Mwanza City, Northwestern Tanzania: a cross-sectional study. BMJ Open 2020; 10:e036211. [PMID: 32895269 PMCID: PMC7476462 DOI: 10.1136/bmjopen-2019-036211] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2019] [Revised: 06/05/2020] [Accepted: 08/07/2020] [Indexed: 11/15/2022] Open
Abstract
BACKGROUND Male involvement in antenatal care (ANC) is among interventions to improve maternal health. Globally male involvement in ANC is low and varies in low-income and middle-income countries including Tanzania where most maternal deaths occur. In Sub-Sahara, men are chief decision makers and highly influence maternal health. In Tanzania information is limited regarding influence of male involvement during ANC on utilisation of maternal health services. OBJECTIVES To determine the effect of male involvement during ANC on use of maternal health services in Mwanza, Tanzania. DESIGN A cross-sectional study conducted from June to July 2019. SETTING This study was conducted at seven randomly selected health facilities providing reproductive, maternal and child health (RCH) services in Mwanza City. PARTICIPANTS Included 430 postpartum women who delivered 1 year prior to the study and attending for RCH services (growth monitoring, vaccination, postpartum care). OUTCOME MEASURES 4 or more ANC visits, skilled birth attendant (SBA) use during childbirth and postnatal care (PNC) utilisation 48 hours after delivery. METHODS Interviews and observation of the women's ANC card were used to collect data. Data was entered, cleaned and analysed by SPSS. RESULTS The mean age of participants was 25.7 years. Of 430 women, 54.4% reported their partners attended ANC at least once, 69.7% reported they attended for four or more ANC visits during last pregnancy, 95% used SBAs during childbirth and 9.2% attended PNC within 48 hours after delivery. Male involvement during ANC was significantly associated with four or more ANC visits (Crude Odds Ratio (COR): 1.90; 95% CI: 1.08-3.35) but not with SBA use or PNC utilisation. CONCLUSION Male involvement in ANC is still low in Mwanza, as 46% of the partners had not attended with partners at ANC. Alternative strategies are needed to improve participation. Studies among men are required to explore the barriers of participation in overall RCH services.

Abstract
BACKGROUND The World Health Organization (WHO) recommends early initiation of breastfeeding within 1 h as it confers many benefits to the child and prevents neonatal mortality. This study aimed to determine the prevalence and factors associated with timely initiation of breastfeeding in the Kilimanjaro region, northern Tanzania. METHODS We analyzed secondary data for 866 participants from a population-based cross-sectional study conducted in April 2016 among mothers with children aged less than 5 years in three districts; Rombo, Same, and Moshi Municipal council in Kilimanjaro region, northern Tanzania. A multistage sampling selected study participants and interviewed using a questionnaire. The generalized linear model, with Poisson family and log-link function was used to estimate the prevalence ratios (PR) and 95% confidence intervals (CI) for factors associated with timely initiation of breastfeeding. RESULTS The prevalence of timely initiation of breastfeeding was 71.1%. The vast majority of mothers (90.7%) gave colostrum, and less than a tenth (6.4%) gave pre-lacteal feed to their children. Adjusted for other factors, not giving children prelacteal feeds remained was significantly associated with a higher prevalence of timely initiation of breastfeeding (PR: 2.22, 95%CI 1.38, 3.56, p = 0.001). There was no significant association between other characteristics and the likelihood of timely initiation of breastfeeding in this study. CONCLUSION The prevalence of timely initiation of breastfeeding in the Kilimanjaro region was higher than the national estimate. The practice of not giving infants prelacteal feeds increased the likelihood of timely initiation of breastfeeding. There is a need to encourage mothers on the significance of recommended ANC visits and early initiation of breastfeeding to their infants to improve the practice.

Abstract
Background: High-risk sexual behaviours (HRSBs) among young adults are a key risk for Sexually Transmitted Infections (STIs), HIV and unplanned pregnancies. The World Health Organization has identified the 15-24 year age-group as high-risk for STIs. Students at Higher Learning Institutions (HLIs) may be at higher risk because they are free of immediate parental supervision, a transient migratory population, and probably at peak years of sexual activity. Here, we describe risky sexual behaviours and preventive practices among young adults attending HLIs in Mbeya, Tanzania. Methods: Cross-sectional study was conducted from March 2019 to January 2020 among students aged 18-24 years enrolled in HLIs within Mbeya. A self-administered questionnaire was used to collect information on sexual health education, activity, behaviour and STI knowledge. Results: 504 students were enrolled; mean age of 21.5 (SD 1.74) years. 377 (74.8%) students were sexually active. Mean age of first sexual encounter was 18.4 years and 11.6% reported their sexual debut was <15 years. A higher proportion of male students (59.7%) reported their sexual debut with non-steady partners compared with female students (40.9%). Lack of condom use at sexual debut was reported by 43.3% of sexually active students. Consistent condom use during the past 4-weeks was reported at 23.3% and 16.9% among men and women, respectively. Almost 1 in 10 students reported being forced into having sex by someone they were dating. Sex under the influence of alcohol was reported by 25.5% of the students. Nearly 7 in 10 (77%) students had heard of STIs, but only 15% were aware STIs could be asymptomatic. Conclusion: STI prevention programs need to recognize young adults in HLIs as an at-risk population. HLIs must advocate targeted messages to minimize risks to acquiring STIs, offer counselling and support for those experiencing sexual violence, and promote condom use and safer-sex negotiation skills.

Validation of self-reported physical activity by accelerometry among primary school children in Kilimanjaro, Tanzania: a pilot study. AAS Open Res 2020; 3:40. [PMID: 34056542 PMCID: PMC8132476 DOI: 10.12688/aasopenres.13118.1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/07/2020] [Indexed: 04/03/2024] Open
Abstract
Background: Self-reports are commonly used to assess physical activity in children. Existing self-reports for physical activity have not been validated for use among primary school children in Kilimanjaro, Tanzania. In order to understand if primary school children can accurately report their physical activity, we examined the validity of self-reported physical activity against accelerometer measured physical activity. Methods: A community based cross-sectional study was conducted from May to July, 2018 among four primary schools in Moshi municipal and Moshi rural districts, Kilimanjaro, Tanzania. A total of 51 primary school children aged 9-11 years were enrolled using a simple random sampling technique. A self-reported questionnaire was used to collect physical activity related variables. In addition, children wore accelerometers for seven consecutive days to capture physical activity movements. Spearman's rank test and Bland Altman plots were used for assessing validity and agreement between self-reports and accelerometer moderate to vigorous physical activity (MVPA). Results: The mean age of the study participants was 10 (SD=0.8) years. Majority of the study participants were female 32 (63%). A moderate, positive correlation was found between self-reports and accelerometer MVPA (rho=0.36, p=0.009). Accelerometer had higher MVPA compared to self-reports. Children who reported walking to school had higher MVPA for both accelerometer and self- reports compared to children who use other means of transport to school, e.g. school buses (p < 0.001). Conclusions: This study found the moderate positive correlation between self-reports and accelerometers. Self-reports are prone to errors due to recall bias, and this interferes their validity. More research is needed to develop better self-reported measures with specific activities which can easily be recalled by children. Also, researchers have to be aware of self-reports validity limitation.

Factors influencing utilization of skilled birth attendant during childbirth in the Southern highlands, Tanzania: a multilevel analysis. BMC Pregnancy Childbirth 2020; 20:420. [PMID: 32711490 PMCID: PMC7382099 DOI: 10.1186/s12884-020-03110-8] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2019] [Accepted: 07/14/2020] [Indexed: 11/10/2022] Open
Abstract
Background Use of skilled health provider (SBA) during and after childbirth has been reported to reduce maternal and newborn deaths; and is one of the key indicators monitored in Sustainable Development Goals (SDGs). Progress, levels and factors influencing utilization of SBA differ within and between countries. In Tanzania, SBA coverage stands at 64% while the national target is 80%; with wide variability between regions (42–96%). This study aimed at determining factors associated with utilization of skilled births providers during childbirth in Mbeya Region, Southern highlands, Tanzania. Methods This was a cross-sectional analytical study conducted in December 2015 to January 2016, in Mbeya Region. A total of 2844 women of reproductive age were enrolled, but only 1777 women who reported a live birth 5 years prior to the survey were included in this analysis. Multilevel logistic regression analyses were used to determine independent factors influencing utilization of SBA during childbirth. Random effects logistic model was used to assess the variability between clusters on the odds of using skilled birth attendants during delivery. Results In this setting, 81% of the women reported utilization of skilled births attendants during childbirth. ANC visits four times or more (aOR = 1.63–95% CI = 1.26, 2.10; p < 0.001) and having secondary education or higher (aOR = 2.16; 95% CI = 1.19–3.90; p = 0.011) were associated with increased SBA use during childbirth whereas having two (aOR = 0.51; 95% CI: 0.33–0.79; p = 0.003) or three children (aOR = 0.37; 95% CI: 0.27–0.58; p < 0.001) relative to one child, 30 to 60 min walking distance to the health facility (aOR = 0.66; 95% CI: 0.48–0.92; p = 0.012) and more than 1 h walking distance to the health facility (aOR = 0.43; 95% CI: 0.32–0.57; p < 0.001) compared to < 30 min; were associated with decreased SBA use during childbirth. Conclusion The proportion of births attended by skilled births attendants was high, but 19% of the women are still left behind. Concentrated efforts to improve utilization of SBA should be targeted to women with low education, with higher number of children, and with low frequency of ANC attendance. Furthermore, community and facility interventions addressing transport for pregnant women are needed. Qualitative study to explore the barriers of SBA use among the 19% who are not using skilled assistance during childbirth is needed.

Abstract
Objective. To identify the bacterial isolates and their antibiotics susceptibility pattern among patients with lower limb ulcers admitted at a tertiary hospital in northern Tanzania. Methodology. A cross-sectional study was conducted between April and July 2018 at the Kilimanjaro Christian Medical Centre. Questionnaire was used to obtain the demographics and clinical information of participants. Wound samples were collected and culture method used to identify the bacteria and their susceptibility patterns. Results. Out of 65 participants, 55 (84.6%) had positive aerobic bacterial growth. Twelve (18 %) participants had more than one bacterium. Fifty-nine (88.1%) were gram-negative bacteria. Proteus vulgaris (13, 19.9%), Pseudomonas spp (10, 14.8%), and Staphylococcus aureus (8, 11.7%) were the common isolates. Out of 59 gram-negative bacterial, 47 (78%) were sensitive to amikacin. Staph were sensitive to oxacillin (75%; n = 8) and vancomycin (50%; n = 8). Gram-negative were common isolates and were resistant to amoxicillin/clavulanic acid but sensitive to amikacin. Conclusion. The observed resistance to antibiotics calls for continuous monitoring of the resistance pattern to guide the empirical management of patients with leg ulcer.

Red meat consumption and its association with hypertension and hyperlipidaemia among adult Maasai pastoralists of Ngorongoro Conservation Area, Tanzania. PLoS One 2020; 15:e0233777. [PMID: 32479535 PMCID: PMC7263614 DOI: 10.1371/journal.pone.0233777] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2019] [Accepted: 05/12/2020] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Red meat is an important dietary source of protein and other essential nutrients. Its high intake has been associated with an increased risk of cardiovascular morbidity and mortality, including hypertension (HTN) and hyperlipidaemia (HLP). Despite being physically active, the Maasai at Ngorongoro Conservation Area (NCA) depend heavily on animals' products as their staple food with fewer intakes of vegetables or fruits due to restriction from carrying out agricultural activities within the NCA. This study aimed at determining the prevalence of HTN and HLP and their association with red meat consumption among adult Maasai of NCA. METHODS A community-based cross-sectional study was conducted in October 2018 using multistage sampling technique. Eight hundred and ninety-four (894) participants enrolled from seven villages in three wards within NCA Data were collected using a modified WHO NCDs-STEPS tool. Anthropometric measurements, blood pressure (BP) measurements, and blood samples for glucose and cholesterol tests were obtained from the study participants. Crude and adjusted prevalence ratio (PR) for factors associated with HTN and HLP were estimated using Ordinal and Bayesian logistic regression models, respectively. RESULTS The prevalence of HLP was 23.7 percent. The levels were higher among males than were among the females (29.0% vs. 20.1%, p = 0.002). The prevalence of HTN and pre-HTN (elevated BP) were 9.8 and 37.0 percent, respectively. Both HTN and elevated BP were higher among males than were among females (hypertensive [10.9% vs. 9.0%]; elevated BP [44.0% vs. 32.1%], p<0.001). The prevalence of HLP was significantly associated with level II (PR = 1.56, 95%CrI: 1.10-2.09) and level III (PR = 1.64, 95%CrI: 1.08-2.41) of red meat consumption as opposed to level I. CONCLUSION The prevalence of hyperlipidaemia and elevated BP were high among NCA Maasai. We found a significant association between red meat consumption and hyperlipidaemia. Further follow-up studies are warranted to establish a temporal relationship between red meat consumption and both conditions.

Prevalence and factors associated with early initiation of breastfeeding among women in Moshi municipal, northern Tanzania. BMC Pregnancy Childbirth 2020; 20:285. [PMID: 32393191 PMCID: PMC7216396 DOI: 10.1186/s12884-020-02966-0] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2019] [Accepted: 04/22/2020] [Indexed: 11/10/2022] Open
Abstract
Background Early initiation of breastfeeding (EIBF) is a predetermining factor for exclusive breastfeeding, and thus a foundation for optimal breastfeeding practices. Rates of EIBF are low globally (42%) and in Tanzania (51%), yet few studies have been done on this issue in Tanzania. This study aimed to determine the prevalence and factors associated with early initiation of breastfeeding among women in northern Tanzania. Methodology This study extracted information from a cohort of 536 women who were followed from 3rd trimester period October 2013 to December 2015 in Moshi municipal, northern Tanzania. The data for this paper was collected by the use of questionnaires at enrolment, delivery and 7 days after delivery. The analysis is based on data from 413 women for whom complete information was obtained. Log binomial regression analysis was used to determine factors associated with early initiation of breastfeeding. Results The prevalence of EIBF was 83%. Overall, women had high knowledge on colostrum (94%), knowledge on exclusive breastfeeding (81%) and time of breastfeeding initiation (71%), but only 54% were counseled on breastfeeding during antenatal care. Knowledge on timely initiation of breastfeeding during pregnancy and vaginal delivery were associated with EIBF. Conclusion Early initiation of breastfeeding is high (83%) in Moshi Municipal but still below the universal coverage recommended by WHO and UNICEF. There is missed opportunity by health facilities to counsel and support early initiation of breastfeeding given high antenatal and facility delivery in this setting. There is a need to evaluate health facility bottle necks to optimal support of early initiation of breastfeeding in Tanzania.

Effect of tuberculosis infection on mortality of HIV-infected patients in Northern Tanzania. Trop Med Health 2020; 48:26. [PMID: 32355448 PMCID: PMC7184680 DOI: 10.1186/s41182-020-00212-z] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2020] [Accepted: 04/16/2020] [Indexed: 12/25/2022] Open
Abstract
Background TB and HIV are public health problems, which have a synergistic effect to each other. Despite the decreasing burden of these two diseases they still make a significant contribution to mortality. Tanzania is among the 30 high TB and HIV burden countries. Methods Routine data over 6 years from people living with HIV (PLHIV) attending health facilities in three regions of Northern Tanzania were analyzed, showing mortality trends from 2012 to 2017 for HIV and HIV/TB subpopulations. Poisson regression with frailty model adjusting for clustering at health facility level was used to analyze the data to determine mortality rate ratios (RR) and 95% confidence intervals (95%CI). Results Among all PLHIV the overall mortality rate was 28.4 (95% CI 27.6–29.2) deaths per 1000 person-years. For PLHIV with no evidence of TB the mortality rates was 26.2 (95% CI 25.4–27.0) per 1000 person-years, and for those with HIV/TB co-infection 57.8 (95% CI 55.6–62.3) per 1000 person-years. After adjusting for age, sex, residence, WHO stage, and bodyweight, PLHIV with TB co-infection had 40% higher mortality than those without TB (RR 1.4; 95% CI 1.24–1.67). Conclusions Over the 6-year period mortality rates for HIV/TB patients were consistently higher than for PLHIV who have no TB. More efforts should be directed into improving nutritional status among HIV patients, as it has destructive interaction with TB for mortality. This will improve patients’ body weight and CD4 counts which are protective against mortality. Among PLHIV attention should be given to those who are in WHO HIV stage 3 or 4 and having TB co-infection.

Determinants of isoniazid preventive therapy completion among people living with HIV attending care and treatment clinics from 2013 to 2017 in Dar es Salaam Region, Tanzania. A cross-sectional analytical study. BMC Infect Dis 2020; 20:276. [PMID: 32276618 PMCID: PMC7147031 DOI: 10.1186/s12879-020-04997-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2019] [Accepted: 03/27/2020] [Indexed: 01/06/2023] Open
Abstract
BACKGROUND Tuberculosis (TB) disease is a common opportunistic infection among people living with HIV (PLHIV). WHO recommends at least 6 months of isoniazid Preventive Therapy (IPT) to reduce the risk of active TB. It is important to monitor the six-month IPT completion since a suboptimal dose may not protect PLHIV from TB infection. This study determined the six-month IPT completion and factors associated with six-month IPT completion among PLHIV aged 15 years or more in Dar es Salaam region, Tanzania. METHODS Secondary analysis of routine data from PLHIV attending 58 care and treatment clinics in Dar es Salaam region was used. PLHIV, aged 15 years and above, who screened negative for TB symptoms and initiated IPT from January, 2013 to June, 2017 were recruited. Modified Poisson regression with robust standard errors was used to estimate prevalence ratios (PR) and 95% confidence interval (CI) for factors associated with IPT completion. Multilevel analysis was used to account for health facility random effects in order to estimate adjusted PR (APR) for factors associated with IPT six-month completion. RESULTS A total of 29,382 PLHIV were initiated IPT, with 21,808 (74%) female. Overall 17,092 (58%) six-month IPT completion, increasing from 42% (773/1857) in year 2013 to 76% (2929/3856) in 2017. Multilevel multivariable model accounting for health facilities as clusters, showed PLHIV who were not on ART had 46% lower IPT completion compared to those were on ART (APR: 0.54: 95%CI: 0.45-0.64). There was 37% lower IPT completion among PLHIV who transferred from another clinic (APR: 0.63: 95% CI (0.54-0.74) compared to those who did not transfer. PLHIV aged 25-34 years had a 6% lower prevalence of IPT completion as compared to those aged 15 to 24 years (APR:0.94 95%CI:0.89-0.98). CONCLUSION The IPT completion rate in PLHIV increased over time, but there was lower IPT completion in PLHIV who transferred from other clinics, who were aged 25 to 34 years and those not on ART. Interventions to support IPT in these groups are urgently needed.

Maternal obesity and intrapartum obstetric complications among pregnant women: Retrospective cohort analysis from medical birth registry in Northern Tanzania. Obes Sci Pract 2020; 6:171-180. [PMID: 32313675 PMCID: PMC7156821 DOI: 10.1002/osp4.395] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2019] [Revised: 11/17/2019] [Accepted: 11/19/2019] [Indexed: 01/07/2023] Open
Abstract
BACKGROUND In the last decade, Tanzania has observed a dramatic increase in overweight and obesity among women of childbearing age, a demographic shift that has been associated with intrapartum obstetric complications in high-income countries. Similar increases in maternal morbidity including postpartum haemorrhage, hypertensive disorders of pregnancy, and rates of caesarean delivery have not yet documented in Tanzania. This analysis describes intrapartum obstetric complications associated with maternal obesity among pregnant women delivering at teaching hospital in Northern Tanzania. METHODS A retrospective cohort analysis was conducted using the hospital's antenatal care (ANC) and birth registries from 2000 to 2015. The World Health Organization (WHO) body mass index (BMI) categories were applied to classify BMI status of pregnant women within 16 weeks of gestational age at their first ANC visit. Relative risk (RR) of obstetric complications with corresponding 95% confidence intervals (CIs) were estimated using multivariable log-binomial regression, adjusting for clustering effect for the correlation between multiple deliveries of the same woman. RESULTS Among 11 873 women who delivered babies in the hospital during the study period, 3139 (26.5%) fit the definition of overweight and 1464 (12.3%) women with obesity. Compared with women with normal weight, women with obesity were at over 2.6 times at risks of experiencing pre-eclampsia/eclampsia (RR: 2.66; 95% CI, 2.08-3.40), pregnancy-induced hypertension (RR 2.13; 95% CI, 1.26-3.62), and postpartum haemorrhage (RR 1.22; 95% CI, 1.00-1.49). Additionally, women with obesity had also higher risk of either elective (RR 2.40; 95% CI, 1.88-3.06) or emergency (RR: 1.53; 95% CI, 1.34-1.75) caesarean delivery. CONCLUSION Maternal obesity is an emerging health problem in Tanzania. This study clearly demonstrates an association between increased risk of intrapartum complications and obesity. A review of guidelines around ANC screening and intrapartum care practices considering BMI, as well as appropriate messages for women with obesity, should be considered to improve maternal and newborn outcomes.

Abstract
People Living with HIV (PLHIV) should be screened for tuberculosis (TB) at every visit to the HIV care and treatment clinic (CTC), and those with positive results on screening should undergo further diagnostic investigations. We evaluated the performance of the TB diagnosis cascade among PLHIV attending CTC between January 2012 and December 2016 in three regions of Tanzania: Dar es Salaam, Iringa, and Njombe. We used descriptive epidemiology to evaluate performance and logistic regression to determine odds ratios (OR) for factors associated with TB screening and further TB diagnosis after positive TB screening. We analyzed 169,741 PLHIV who made 2,638,876 visits to CTC between January 2012 and December 2016. We excluded 2,074 (0.80%) visits as these involved PLHIV enrolled in CTC with a prior TB disease diagnosis. Of the 2,636,802 visits, 2,524,494 (95.67%) had TB screening according to national guidelines, of which 88,028 (3.49%) had TB screening positive results. Of the 88,028 visits with a positive TB screening, 27,810 (31.59%) had no records for further TB diagnosis following positive TB screening. Of all visits with positive TB screening, 32,986 (37.50%) had a TB disease diagnosis. On multivariate logistic regression, those who visited with World Health Organization (WHO) clinical stage four (aOR = 3.61, 95% CI 3.48–3.75, P < 0.001), enrolled in health center (aOR = 1.26, 95% CI 1.24–1.29, P < 0.001), enrolled in Iringa region (aOR = 1.54, 95% CI 1.50–1.57, P < 0.001), and enrolled in 2015 (aOR = 1.20, 95% CI 1.18–1.24, P < 0.001) were more likely to have no TB screening. Visits involving those who were of the female sex (aOR = 1.14, 95% CI 1.11–1.18, P < 0.001), enrolled in Njombe region (aOR = 4.36, 95% CI 4.09–4.65, P < 0.001), and enrolled in 2016 (aOR = 2.62, 95% CI 2.49–2.77, P < 0.001) were more likely to have no further TB diagnosis after positive TB screening. The study documented high performance of TB screening for PLHIV in HIV CTCs but a low transition of presumptive TB case undergoing further investigations. Better systems are needed for ensuring presumptive TB cases are diagnosed including using more efficient diagnostic methods like Gene pert.

Abstract
Background: Anemia is a severe public health problem affecting more than half of children under five years of age in low-, middle- and high-income countries. The study aimed to determine the prevalence and factors associated with anemia among children under five years of age in northern Tanzania. Methods: This community-based cross-sectional study was conducted in Rombo district, Kilimanjaro region, northern Tanzania, in April 2016. Multistage sampling technique was used to select a total of 602 consenting mothers and their children aged 6-59 months and interviewed using a questionnaire. Data were analyzed using Stata version 15.1. We used generalized linear models (binomial family and logit link function) with a robust variance estimator to determine factors associated with anemia. Results: Prevalence of anemia was 37.9%, and it was significantly higher among children aged 6-23 months (48.3%) compared to those aged 24-59 months (28.5%). There were no significant differences in anemia prevalence by sex of the child. Adjusted for other factors, children aged 6-23 months had over two times higher odds of being anemic (OR=2.47, 95% CI 1.73, 3.53, p<0.001) compared to those aged 24-59 months. No significant association was found between maternal and nutritional characteristics with anemia among children in this study. Conclusion: Prevalence of anemia was lower than the national and regional estimates, and it still constitutes a significant public health problem, especially among children aged 6-23 months. The study recommends iron supplementation, food fortification, dietary diversification, and management of childhood illnesses interventions for mothers and children under two years.

Prevalence and factors associated with HIV and syphilis infection among children aged 0-36 months in Kilimanjaro, Tanzania: a community-based cross-sectional study. Trop Med Health 2019; 47:53. [PMID: 31832013 PMCID: PMC6868844 DOI: 10.1186/s41182-019-0183-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2019] [Accepted: 10/07/2019] [Indexed: 11/16/2022] Open
Abstract
Background Childhood mortality is high in sub-Saharan Africa. Mother-to-child transmission (MTCT) of HIV and congenital syphilis are among significant causes. Dual elimination of these two infections is one of the international goals. Community-based studies on the burden of HIV and syphilis among children will contribute to fine-tuning the interventions to achieve the elimination goal. This study aims to describe the prevalence of HIV and syphilis among children aged 0–36 months and associated factors in northern Tanzania. Methods This was a community-based cross-sectional study, which was conducted in all the seven districts of Kilimanjaro region. Multistage sampling was used, and a total of 2452 children aged 0 to 36 months and their primary caretakers were enrolled. Interviews were conducted with the mother/caretaker, and dried blood samples were collected from the children and processed for laboratory diagnosis of HIV and syphilis. HIV ELISA was first performed on all the samples. Positive samples of children < 18 months were confirmed using PCR. Results The prevalence of HIV among 2452 children aged 0–36 months was 1.7% (n = 42). There was a significant difference in the distribution of HIV by age of the child, maternal antenatal attendance, and breastfeeding history. The prevalence of syphilis was 0.4% (n = 10). Five of the children were more than 1 year old. All children with a positive test for syphilis were from Moshi rural district, and their mothers consumed alcohol. No child was co-infected with HIV and syphilis. Conclusions Though the prevalence of the two infections was low, detecting syphilis in children suggests a missed opportunity in screening women during pregnancy. The region may be on track with the goal to achieve dual elimination of mother-to-child transmitted HIV and syphilis. However, efforts are needed to reduce missed opportunities for screening women for syphilis and HIV early in pregnancy and retesting at 3rd trimester/delivery. Strategies to improve testing for HIV-exposed children are needed.

Abstract
HIV prevention efforts have historically focused on people aged 15–49 years, despite mounting evidence of risk behavior and increased disease burden among older adults. We analyzed survey data from 600 adults aged ≥50 years in the Rombo District of Tanzania. Logistic regression models were performed to evaluate individual and partner-level factors associated with HIV testing and counseling (HTC) uptake. In this sample, more than half of participants were sexually active and condom use was rare, but only 57% had ever been tested for HIV. Ten were HIV infected (1.7%); this prevalence was approximately one-third that observed among the general population in Tanzania (4.7%). Individual factors associated with increased HTC uptake included younger age, female gender, greater educational attainment, and having health insurance. Partner factors associated with increased HTC uptake included lower partner age and higher partner education. This population demonstrated substantial HIV risk, warranting tailored interventions to raise awareness and increase HTC uptake.

Incidence Rates for Tuberculosis Among HIV Infected Patients in Northern Tanzania. Front Public Health 2019; 7:306. [PMID: 31709218 PMCID: PMC6821649 DOI: 10.3389/fpubh.2019.00306] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2019] [Accepted: 10/07/2019] [Indexed: 12/21/2022] Open
Abstract
Background: HIV and tuberculosis (TB) are leading infectious diseases, with a high risk of co-infection. The risk of TB in people living with HIV (PLHIV) is high soon after sero-conversion and increases as the CD4 counts are depleted. Methodology: We used routinely collected data from Care and Treatment Clinics (CTCs) in three regions in northern Tanzania. All PLHIV attending CTCs between January 2012 to December 2017 were included in the analysis. TB incidence was defined as cases started on anti-TB medications divided by the person-years of follow-up. Poisson regression with frailty models were used to determine incidence rate ratios (IRR) and 95% confidence intervals (95% CI) for predictors of TB incidences among HIV positive patients. Results: Among 78,748 PLHIV, 405 patients developed TB over 195,296 person-years of follow-up, giving an overall TB incidence rate of 2.08 per 1,000 person-years. There was an increased risk of TB incidence, 3.35 per 1,000 person-years, in hospitals compared to lower level health facilities. Compared to CD4 counts of <350 cells/μl, a high CD4 count was associated with lower TB incidence, 81% lower for a CD4 count of 350–500 cells/μl (IRR 0.19, 95% CI 0.04–0.08) and 85% lower for those with a CD4 count above 500 cells/μl (IRR 0.15, 95% CI 0.04–0.64). Independently, those taking ART had 66% lower TB incidences (IRR 0.34, 95% CI 0.15–0.79) compared to those not taking ART. Poor nutritional status and CTC enrollment between 2008 and 2012 were associated with higher TB incidences IRR 9.27 (95% CI 2.15–39.95) and IRR 2.97 (95% CI 1.05–8.43), respectively. Discussion: There has been a decline in TB incidence since 2012, with exception of the year 2017 whereby there was higher TB incidence probably due to better diagnosis of TB following a national initiative. Among HIV positive patients attending CTCs, poor nutritional status, low CD4 counts and not taking ART treatment were associated with higher TB incidence, highlighting the need to get PLHIV on treatment early, and the need for close monitoring of CD4 counts. Data from routinely collected and available health services can be used to provide evidence of the epidemiological risk of TB.

Awareness and Factors Associated with Health Care Worker's Knowledge on Rubella Infection: A Study after the Introduction of Rubella Vaccine in Tanzania. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16101676. [PMID: 31091685 PMCID: PMC6571888 DOI: 10.3390/ijerph16101676] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/14/2019] [Revised: 05/11/2019] [Accepted: 05/12/2019] [Indexed: 11/16/2022]
Abstract
Background Congenital rubella syndrome is a global health problem. The incidence is much higher in Africa and Southeast Asia than the rest of the world, especially in countries where universal rubella vaccination has not been implemented. Healthcare worker's knowledge on rubella infection and the rubella vaccine is of utmost importance in achieving and maintaining vaccination coverage targets. This study aimed to assess health care workers knowledge on rubella infection in Kilimanjaro Tanzania, after the introduction of a rubella vaccination. Methods This was a health facility-based cross sectional study. It was conducted in three districts of the Kilimanjaro region between August and October 2016. The study involved eligible health care workers in selected health facilities. An interview guide was used for collecting information by face-to-face interviews. Multivariate analysis was used to assess factors associated with rubella knowledge among healthcare workers. Results A total of 126 health care workers were interviewed. An acceptable level of knowledge was considered if all five questions about rubella were correctly answered. Only 26.4% (n = 31) answered all questions correctly. In multivariate analysis education level and working department were predictors of rubella knowledge; health care workers with an advanced diploma had an adjusted odds ratio (AOR) of 7.7 (95% Confidence interval; CI: 1.4, 41.0), those with a university degree (AOR: 10; 95% CI: 2.4; 42.5) and health care workers in the outpatient department (AOR: 0.06; 95% CI: 0.04; 0.29). Conclusions Our study confirmed that health care worker's knowledge on rubella infection was low in the areas where rubella vaccination had been introduced. We recommend continuous education and supportive supervision post vaccine introduction in order to increase healthcare worker's knowledge on rubella infection, congenital rubella syndrome and prevention through sustained high vaccination coverage.
