High prevalence of hypertension and of risk factors for non-communicable diseases (NCDs): a population based cross-sectional survey of NCDS and HIV infection in Northwestern Tanzania and Southern Uganda

Determinants of change in blood pressure in Ghana: Longitudinal data from WHO-SAGE Waves 1-3

The prevalence of hypertension is increasing in low- and middle-income countries, however statistics are generally derived from cross sectional surveys that utilize different methodologies and population samples. We investigated blood pressure (BP) changes over 11-12 years in a large cohort of adults aged 50 years and older (n = 820) included in the World Health Organization's Study on global AGEing and adult health (WHO-SAGE Ghana) Wave 1 (2007/8) with follow up in Wave 3 (2019). Participants' BP were measured in triplicate and a survey completed at both time points. Survey instruments collected information on sociodemographic characteristics, lifestyle, health behaviors and chronic conditions. While no significant difference was found in systolic BP between Waves 1 and 3, diastolic BP decreased by 9.7mmHg (mean = 88.6, 15.4 to 78.9, 13.6 respectively) and pulse pressure increased by 9.5mmHg (44.8, 13.7 to 54.3, 14.1). Awareness of hypertension increased by 37%, from (20% to 57%), but no differences were found for the proportion of hypertensives receiving treatment nor those that had controlled BP. Mixed effects modelling showed a decrease in diastolic BP was associated with increasing age, living in rural areas and having health insurance. Factors associated with an increased awareness of hypertension were residing in urban areas, having health insurance and increasing body mass index. While diagnosis of hypertension has improved over time in Ghana, there is an ongoing need to improve its treatment in older adults.

Community health workers' involvement in the prevention and control of non-communicable diseases in Wakiso District, Uganda

Background

Community health workers (CHWs) are an important cadre of the global health workforce as they are involved in providing health services at the community level. However, evidence on the role of CHWs in delivering interventions for non-communicable diseases (NCDs) in Uganda is limited. This study, therefore, assessed the involvement of CHWs in the prevention and control of NCDs in Wakiso District, Uganda with a focus on their knowledge, attitudes and practices, as well as community perceptions.

Methods

A cross-sectional study using mixed methods was conducted which involved a structured questionnaire among 485 CHWs, and 6 focus group discussions (FGDs) among community members. The study assessed knowledge, perceptions including the importance of the various risk factors, and the current involvement of CHWs in NCDs, including the challenges they faced. Quantitative data were analysed in STATA version 13.0 while thematic analysis was used for the qualitative data.

Results

The majority of CHWs (75.3%) correctly defined what NCDs are. Among CHWs who knew examples of NCDs (87.4%), the majority mentioned high blood pressure (77.1%), diabetes (73.4%) and cancer (63.0%). Many CHWs said that healthy diet (86.2%), physical activity (77.7%), avoiding smoking/tobacco use (70.9%), and limiting alcohol consumption (63.7%) were very important to prevent NCDs. Although more than half of the CHWs (63.1%) reported being involved in NCDs activities, only 20.9 and 20.6% had participated in community mobilisation and referral of patients respectively. The majority of CHWs (80.1%) who were involved in NCDs prevention and control reported challenges including inadequate knowledge (58.4%), lack of training (37.6%), and negative community perception towards NCDs (35.1%). From the FGDs, community members were concerned that CHWs did not have enough training on NCDs hence lacked enough information. Therefore, the community did not have much confidence in them regarding NCDs, hence rarely consulted them concerning these diseases.

Conclusions

Despite CHWs having some knowledge on NCDs and their risk factors, their involvement in the prevention and control of the diseases was low. Through enhanced training and community engagement, CHWs can contribute to the prevention and control of NCDs, including health education and community mobilisation.

Increased prevalence of hypertension in Ghana: New 2017 American College of Cardiology/American Hypertension Association hypertension guidelines application

Background

We estimated the prevalence and socio-demographic risk factors of hypertension among Ghanaian adults as per the Joint National Committee 7 and the 2017 American College of Cardiology/American Hypertension Association hypertension thresholds used for diagnosis and treatment.

Methods

This cross-sectional analysis included 12 151 adults (8295 females and 3856 males) aged 18 years or older who participated in the 2014 Ghana Demographic and health Survey. Multiple logistic regression models were applied to obtain risk factors associated with hypertension as per both guidelines.

Results

Overall, 30.43% (n = 3698) and 11.48% (n = 1395) respondents had hypertension as per the 2017 ACC/AHA and JNC7 guidelines, respectively. The following factors were significant according to the 2017 ACC/AHA guideline: 55-64 years (adjusted odds ratio (aOR) = 6.42, 95% confidence interval (CI): 4.70-8.77), 45-54 years (aOR = 5.72, 95% CI = 4.70-6.85), 3544 years (aOR = 3.91, 95% CI = 3.33-4.59), and 25-34 years (aOR = 2.05, 95% CI = 1.77-2.37) age groups. Males (aOR = 1.39, 95% CI = 1.23-1.53), and urban residents (aOR = 1.18, 95% CI = 1.05-1.38). All the above risk factors were significant according to the JNC7 guideline too. Factors positively associated with only the 2017 ACC/AHA guideline included: middle income (aOR = 1.20, 95% CI = 1.02-1.42) and richest (aOR = 1.36, 95% CI = 1.10-1.69) wealth quintiles, whereas manual (aOR = 1.37, 95% CI = 1.02-1.86) was positively associated with the JNC7 guidelines only.

Conclusions

We conclude that adopting the ACC/AHA guidelines would lead to a substantial increase in the prevalence of hypertension among Ghanaian adults, thus, hypertension prevention and control should be prioritized.

Prevalence and factors that are associated with elevated blood pressure among primary school children in Mwanza Region, Tanzania

Introduction

hypertension (HTN) among children is reported to be increasing due to sedentary lifestyles. In developed countries the prevalence of paediatric HTN is recorded to be up to 21% while the magnitude of the same is up to 11% in Tanzania. This study aimed to determine the blood pressure profile and factors associated with elevated blood pressure (BP) among children of Mwanza region.

Methods

a cross sectional study involving 742 children aged 6 to 16 years in selected primary schools in Mwanza region was conducted from June to August 2019. Data were collected using self-administered structured questionnaires where parents helped children to fill in. Blood pressure, body weight and height were measured using digital portable sphygmomanometer, self-calibrating digital weighing scale and Shorr measuring board respectively. Data were analyzed using EpiInfo.

Results

this study found mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 109.2 ± 8.1 mmHg and 62.3 ± 7.2 mmHg respectively. Prevalence of elevated BP was 18.1%. Pre-hypertension 9.6%, and hypertension 8.5%. The age specific elevated BP prevalence was significantly higher (OR = 1.9, 95% CI: 1.2 - 2.9, p = 0.008) among children aged ≥10 years (21.4%) than younger ones (15.1%). Prevalence was also higher (OR = 1.5, 95% CI: 1.1 - 2.3, p = 0.048) among girls (20.1%) than boys (16.0%). Elevated BP was found to be associated with obesity (OR = 3.5, 95% CI: 1.6 - 7.7, p = <0.001), overweight (OR = 1.9, 95% CI: 1.1 - 3.3, p = 0.037), eating fried food (OR = 2.2, 95% CI: 1.1 - 4.4, p = 0.023), drinking sugar soft drinks (OR = 2.0, 95% CI: 1.2 - 3.5, p = 0.002) and not eating fruits (OR = 13.4, 1.6, 95% CI: 2.1 - 65.8, p-value 0.006).

Conclusion

findings indicate high prevalence of elevated BP among children of Mwanza region. There was an association between elevated BP and increased age, gender, sedentary lifestyle and obesity. Importance of measuring paediatric blood pressure and health information regarding effects of sedentary life is recommended to Tanzanians. Parents should encourage their children to have active physical activities. Moreover, health workers should implement programmes to modify sedentary lifestyle and prevent children from elevated blood pressure.

Application of one health approach in training at Makerere University: experiences from the one health workforce project in Uganda

The interconnections of humans, domestic animals, wildlife and the environment have increasingly become complex, requiring innovative and collaborative approaches (One Health approach) for addressing global health challenges. One Health is a multidisciplinary and multi-sectoral collaborative approach to human, animal, plant and environmental health. The role of academia in training professionals oriented in One Health is critical in building a global workforce capable of enhancing synergies of various sectors in improving health. Makerere University, Uganda has implemented pre-service capacity building initiatives aimed to foster One Health competencies among students who are future practitioners. In addition to incorporating the One Health concept in didactic curricula, Student One Health Innovation Clubs, undergraduate field placements in 11 demonstration sites, graduate fellowships, small grants to support research and innovations, and cross-college collaborative training approaches have greatly aided the assimilation of One Health into the fabric of university offerings. Partnerships with government ministries, private sector and international agencies were initiated to benefit the students, as well as chart a path for experiential learning and in-service offerings in the future. One major challenge, however, has been the tendency to focus on infectious diseases, especially zoonoses, with less consideration of other health issues. The opportunity for improvement, nonetheless, lies in the increasing emerging and re-emerging health concerns including epidemics, environmental pollution and related challenges which justify the need for countries and institutions to focus on building and strengthening multidisciplinary health systems.

Comparison of self-reports and biomedical measurements on hypertension and diabetes among older adults in China

Background

Researchers interested in the effects of health on various life outcomes often use self-reported health and disease as an indicator of true, underlying health status. However, the validity of reporting is questionable as it relies on the awareness, recall bias and social desirability. Accordingly, biomedical test is generally regarded as a more precise indication of the disease.

Methods

Using data from the third wave of China Health and Retirement Longitudinal Study (CHARLS), we selected individuals aged 40–85 years old who participated in both health interview survey and biomedical test. Sensitivity, specificity, false negative reporting and false positive reporting were used as measurements of (dis) agreement or (in) validity, and binary and multinomial logistic regression were used to estimate under-report or over-report of hypertension and diabetes.

Results

Self-reported hypertension and diabetes showed low sensitivity (73.24 and 49.21%, respectively) but high specificity (93.61 and 98.05%, respectively). False positive reporting of hypertension and diabetes were 3.97 and 1.67%, while false negative reports were extremely high at 10.14 and 7.38%. Educational attainment, hukou, age and gender affected both group-specific error and overall error with some differences in their magnitude and directions.

Conclusion

Self-reported conditions underestimate the disease burden of hypertension and diabetes in China. Adding objective measurements into social survey could improve data accuracy and allow better understanding of socioeconomic inequalities in health. Furthermore, there is an urgent need to provide basic health education and physical examination to citizens, and promote the use of healthcare to lower the incidence and unawareness of disease in China.

Prevalence and determinants of hypertension among pastoralists in Monduli District, Arusha region in Tanzania: a cross-sectional study

Background

Hypertension is among the growing non-communicable diseases (NCDs) in developing countries and the leading cause of death worldwide. Pastoral areas have been identified to be at a higher risk of diseases due to challenges in their daily food production, livelihoods or mobility. Unfortunately, the prevalence of hypertension and the risk factors particularly affecting rural and pastoral populations are not fully understood, making intervention efforts challenging. The aim of this study was to determine the prevalence of hypertension and identify the risk factors among adults living in Monduli district in Tanzania. The findings will be useful for the provision of tailored interventions focused on community-specific nutritional and behavioral practices.

Methods

We conducted a community based cross-sectional study involving a sample of 510 adults aged above 18 years selected using a multistage cluster sampling in the Monduli district of Arusha region, Tanzania. Data were collected by using interviewer-administered questionnaires containing socio-demographic, physical activity, smoking and alcohol consumption. Anthropometry, systolic (SBP) and diastolic blood pressure (DBP) levels were measured. A one-day 24 h diet recall was conducted to evaluate the dietary habits of all participants. Both linear and logistic regression analysis were used to identify the independent predictors for hypertension and blood pressure levels.

Results

The prevalence of hypertension in this study was 25.7% (n = 131, 95% CI; 22.1–29.7). The odds of hypertension increased with being male (AOR = 1.75, 95%CI, 1.06–2.88), belonging to the older age group of 30–39 year olds (AOR = 3.3, 95%CI, 1.76–6.38), 40–59 year olds (AOR = 3.34, 95%CI, 1.75–6.37) and ≥ 60 year olds (AOR = 4.2, 95%CI, 2.02–8.87), being overweight or obese (AOR = 3.37, 95%CI, 1.18–9.62), have more hours spent sedentary (AOR = 3.19, 95%CI, 1.61–6.32), and consumption of fatty foods (AOR = 2.23, 95%CI, 1.27–3.93). The odds for hypertension was significantly reduced among participants who reported higher income (AOR = 0.47, 95% CI, 0.25–0.91), high level of physical activity (AOR = 0.55, 95%CI, 0.31–0.96) and those reported to consume fruit (AOR = 0.37, 95% CI, 0.18–0.77). Consumption of cereals was negatively associated with levels of SBP (β = − 17.4, 95% CI, − 23.8; − 11.0) and DBP (β = − 6.6, 95% CI, − 11.5,-1.79).

Conclusion

About one in every four adults living in pastoral communities have been found to have hypertension in this study. Our findings suggest that older age, obesity or overweight, low physical activity, low income, and consumption of fatty foods increase the risk of hypertension among study population. Their diet was dominated by cereals with moderate intake of meat and milk and low fruits. There is a need to promote physical activities and consumption of fruits in the study population in order to fight against hypertension. Further research should be done to confirm the associations.

Prevalence and Factors Associated With Liver Fibrosis Among Adult HIV-Infected Patients Attending Urban and Rural Care Clinics in Uganda

Background

Liver fibrosis is common among HIV-infected patients. Risk factors vary by location. Understanding this variation may inform prevention strategies. We compared the prevalence and correlates of liver fibrosis among HIV-infected patients attending care clinics in Uganda.

Methods

This was a cross-sectional study involving 2030 HIV-infected patients attending care clinics in urban and rural Uganda. Liver fibrosis was defined as liver stiffness measurement (LSM) >7.1 KPa. Proportions and correlates of liver fibrosis were assessed and compared using logistic regression stratified by gender and site.

Results

Prevalence of liver fibrosis was higher among participants in the rural clinic (15% vs 11%; P = .017). History of tobacco use (urban P = .022; rural P = .035) and serologic evidence of hepatitis C infection (HCV; urban P = .028; rural P = .03) was associated with liver fibrosis in all men. Elevated liver transaminases (urban P = .002; rural P = .028) and increasing age (urban P = .008; rural P = .052) were risk factors among all women. Tobacco use among women was only a risk factor in those attending the rural clinic (P = .003), and detectable HIV viral load (P = .002) for men in the urban clinic.

Conclusions

Liver fibrosis is prevalent among HIV-infected persons in Uganda. HIV viral suppression and avoiding tobacco may be strategies to prevent liver fibrosis and cancer risk.

A comparison of HIV outpatient care in primary and secondary healthcare-level settings in Zimbabwe

Setting

Decentralisation of HIV care to nurse-led primary care services is being implemented across low- and middle-income countries in sub-Saharan Africa.

Objective

To compare services offered to clients attending for HIV care at a physician-led and a nurse-led service in Harare, Zimbabwe.

Design

A cross-sectional study was performed at Harare Central Hospital (HCH) and Budiriro Primary Care Clinic (PCC) from June to August 2018. An interviewer-administered questionnaire was used to collect sociodemographics, HIV treatment and clinical history from clients attending for routine HIV care. The Mann-Whitney U-test was used to evaluate for differences between groups for continuous variables. For categorical variables, the χ² test was used.

Results

The median age of the 404 participants recruited was 38 years (IQR 28-47); 69% were female. Viral suppression was comparable between sites (HCH, 70% vs. PCC, 80%; P = 0.07); however, screening for comorbidities such as cervical cancer screening (HCH, 61% vs. PCC, 41%; P = 0.001) and provision of referral services (HCH, 23% vs. PCC, 13%; P = 0.01) differed between sites.

Conclusion

Efforts to improve service provision in primary care settings are needed to ensure equity for users of health services.

Blood pressure, T cells, and mortality in people with HIV in Tanzania during the first 2 years of antiretroviral therapy

Cardiovascular disease is now a leading cause of mortality in people with HIV (PWH). High blood pressure is the major driver of cardiovascular disease. Despite this, little is known about blood pressure in PWH during the early years of antiretroviral therapy (ART). In this prospective cohort study in Tanzania, the authors conducted unobserved blood pressure measurements at enrollment, 3, 6, 12, 18, and 24 months in 500 PWH initiating ART and 504 HIV-uninfected adults. The authors excluded measurements taken on antihypertensive medications. Although PWH had a significantly lower blood pressure before ART initiation, they had a significantly greater increase in blood pressure during the first 2 years of ART compared to HIV-uninfected controls. Blood pressure correlates in PWH differed from HIV-uninfected controls. In PWH, lower baseline CD4⁺ T-cell counts were associated with lower blood pressure, and greater increases in CD4⁺ T-cell counts on ART were associated with greater increases in blood pressure, both on average and within individuals. In addition, PWH with a systolic blood pressure (SBP) <90 mm Hg at the time of ART initiation had ~30% mortality in the following 3 months due to occult infections. These patients require careful investigation for occult infections, and those with tuberculosis may benefit from corticosteroids.

Contrasting impact of rural, versus urban, living on glucose metabolism and blood pressure in Uganda

Background: The burden of cardiometabolic diseases, including cardiovascular diseases and diabetes, is increasing in sub-Saharan Africa and this has been linked to urbanisation. Helminths, through their immunomodulatory properties, may protect against these disorders. We hypothesised that the rural environment protects against cardiometabolic diseases and that helminths may influence rural-urban disparity of cardiometabolic disease risk. Methods: We compared metabolic parameters of individuals aged ≥10 years living in rural, high-helminth-transmission and urban, lower-helminth-transmission settings in Uganda. Cross-sectional surveys were conducted in rural Lake Victoria island fishing communities and in urban sub-wards in Entebbe municipality. Helminth infection and outcomes, including insulin resistance (computed using the homeostatic model assessment of insulin resistance [HOMA-IR]), fasting blood glucose, fasting blood lipids, blood pressure, body mass index (BMI), waist and hip circumference, were assessed. Results: We analysed 1,898 rural and 930 urban participants. Adjusting for BMI, exercise, smoking, alcohol intake, age and sex, urban residents had lower mean fasting glucose (adjusted mean difference [95%CI] 0.18 [-0.32, -0.05] p=0.01) and HOMA-IR (-0.26 [-0.40, -0.11] p=0.001) but higher blood pressure (systolic, 5.45 [3.75, 7.15] p<0.001; diastolic, 1.93 [0.57, 3.29] p=0.006). Current helminth infection did not explain the observed differences. Conclusions: In the Ugandan context, living in rural fishing communities may protect against hypertension but worsen glucose metabolism.

Clinical characteristics and health care received among patients with type 2 diabetes attending secondary and tertiary healthcare facilities in Mwanza Region, Tanzania: a cross-sectional study

BACKGROUND

Tanzania is among the sub-Saharan African countries facing a tremendous increase in the burden of type 2 diabetes mellitus. In order to provide diabetes health care services, the government has established diabetes care clinics in secondary and tertiary healthcare facilities. However, previous studies have demonstrated a disparity in availability of supplies and equipment for provision of diabetes health care services at these healthcare facilities. This study aims to assess the clinical characteristics and health care received among patients with type 2 diabetes attending secondary and tertiary healthcare facilities in Mwanza Region, Tanzania.

METHODS

A cross-sectional study was conducted in Mwanza Region from June to September, 2018.Three hundred and thirty patients were selected by systematic random sampling from three healthcare facilities. A structured questionnaire was utilized to collect information on patient characteristics, health care received and patient perception of care. Patient blood pressure, blood glucose, weight and height were measured during the study. Percentages, chi-square tests and multivariable analysis were conducted to obtain the proportions, make comparisons and determining the correlates of tertiary-level healthcare facility.

RESULTS

Approximately half of respondents (54.5%) were from secondary healthcare facilities. The prevalence of hypertension (63.3%), hyperglycemia (95.8%) and obesity (93.3%) were high. The prevalence of hyperglycemia was slightly higher at secondary-level healthcare facility (p = 0.005). The proportion of respondents recently diagnosed with diabetes (≤ 10 years) was significantly higher at tertiary-level healthcare facility (p = 0.000). The prevalence of diabetes related complications was higher at tertiary-level healthcare facility (80.7% versus 53.3%, p = 0.000). Assessments of body weight, blood pressure, blood glucose, feet and eye examination were conducted on a monthly basis at all facilities. None of the respondents had undergone lipid profile testing. All of the respondents (100%) received care from a nurse during diabetes clinic visits and half of the respondents (49.7%) also received care from a clinician. Relatively young patients, married and recently diagnosed patients were more likely to attend clinic at tertiary facilities. Tertiary-level healthcare facilities were more likely to have patients with complications and to have a dietitian available at the clinic.

Contemporary issues and new challenges in chronic kidney disease amongst people living with HIV

Chronic kidney disease (CKD) is a comorbidity of major clinical significance amongst people living with HIV (PLWHIV) and is associated with significant morbidity and mortality. The prevalence of CKD is rising, despite the widespread use of antiretroviral therapy (ART) and is increasingly related to prevalent non-infectious comorbidities (NICMs) and antiretroviral toxicity. There are great disparities evident, with the highest prevalence of CKD among PLWHIV seen in the African continent. The aetiology of kidney disease amongst PLWHIV includes HIV-related diseases, such as classic HIV-associated nephropathy or immune complex disease, CKD related to NICMs and CKD from antiretroviral toxicity. CKD, once established, is often relentlessly progressive and can lead to end-stage renal disease (ESRD). Identifying patients with risk factors for CKD, and appropriate screening for the early detection of CKD are vital to improve patient outcomes. Adherence to screening guidelines is variable, and often poor. The progression of CKD may be slowed with certain clinical interventions; however, data derived from studies involving PLWHIV with CKD are sparse and this represent an important area for future research. The control of blood pressure using angiotensin converting enzyme inhibitors and angiotensin receptor blockers, in particular, in the setting of proteinuria, likely slows the progression of CKD among PLWHIV. The cohort of PLWHIV is facing new challenges in regards to polypharmacy, drug-drug interactions and adverse drug reactions. The potential nephrotoxicity of ART is important, particularly as cumulative ART exposure increases as the cohort of PLWHIV ages. The number of PLWHIV with ESRD is increasing. PLWHIV should not be denied access to renal replacement therapy, either dialysis or kidney transplantation, based on their HIV status. Kidney transplantation amongst PLWHIV is successful and associated with an improved prognosis compared to remaining on dialysis. As the cohort of PLWHIV ages, comorbidity increases and CKD becomes more prevalent; models of care need to evolve to meet the new and changing chronic healthcare needs of these patients.

Medicinal Plants Used in Traditional Management of Cancer in Uganda: A Review of Ethnobotanical Surveys, Phytochemistry, and Anticancer Studies

The burden of neoplastic diseases is a significant global health challenge accounting for thousands of deaths. In Uganda, about 32,617 cancer cases were reported in 2018, accompanied by 21,829 deaths. In a view to identify some potential anticancer plant candidates for possible drug development, the current study was designed to compile the inventory of plants with reported anticancer activity used in rural Uganda and the evidences supporting their use in cancer therapy. An electronic survey in multidisciplinary databases revealed that 29 plant species belonging to 28 genera distributed among 24 families have been reported to be used in the management of cancer in Uganda. Anticancer plants were majorly from the families Bignoniaceae (7%), Caricaceae (7%), Fabaceae (7%), Moraceae (7%), and Rutaceae (7%). Most species occur in the wild (52%), though some are cultivated (48%). The growth habit of the plants is as trees (55%) or herbs (45%). Anticancer extracts are usually prepared from leaves (29%), bark (24%), roots (21%), and fruits (13%) through decoctions (53%), as food spices (23%) or pounded to produce ointments that are applied topically (10%). Prunus africana (Hook.f.) Kalkman, Opuntia species, Albizia coriaria (Welw. ex Oliver), Daucus carota L., Cyperus alatus (Nees) F. Muell., Markhamia lutea (Benth.) K. Schum., and Oxalis corniculata L. were the most frequently encountered species. As per global reports, Allium sativum L., Annona muricata L., Carica papaya L., Moringa oleifera Lam., Opuntia species, Prunus africana (Hook.f.) Kalkman, and Catharanthus roseus (L.) G. Don. are the most studied species, with the latter having vincristine and vinblastine anticancer drugs developed from it. Prostate, cervical, breast, and skin cancers are the top traditionally treated malignancies. There is a need to isolate and evaluate the anticancer potential of the bioactive compounds in the unstudied claimed plants, such as Cyperus alatus (Nees) F. Muell., Ficus dawei Hutch., Ficus natalensis Hochst., and Lovoa trichilioides Harms, and elucidate their mechanism of anticancer activity.

Helminth infection and outcomes, including insulin resistance (computed using the homeostatic model assessment of insulin resistance [HOMA-IR]), fasting blood glucose, fasting blood lipids, blood pressure, body mass index (BMI), waist and hip circumference, were assessed. Results: We analysed 1,898 rural and 930 urban participants. Adjusting for BMI, exercise, smoking, alcohol intake, age and sex, urban residents had lower mean fasting glucose (adjusted mean difference [95%CI] -0.13 [-0.24, -0.01] p=0.04) and HOMA-IR (-0.13 [-0.25, -0.01] p=0.04) but higher blood pressure (systolic, 4.64 [3.23, 6.06] p<0.001; diastolic, 1.89 [0.81, 2.97] p=0.001). Current helminth infection did not explain the observed differences. Conclusions: In low-income countries, rural living may protect against hypertension but impair glucose metabolism.

The prevalence of selected non-communicable disease risk factors among HIV patients on anti-retroviral therapy in Bushbuckridge sub-district, Mpumalanga province

Background

The rates of non-communicable diseases (NCD’s) appear to be increasing in human immunodeficiency virus (HIV) infected people as compared to non-HIV infected people and this will have major implications for clinical care. The aim of the current study was to profile selected cardiovascular disease risk factors among HIV patients on anti-retroviral therapy (ART) in Bushbuckridge sub-district.

Methods

The current study followed a quantitative cross-sectional study design using a questionnaire which was adapted from World Health Organization STEPwise approach to Surveillance (WHO STEPS). Participants were HIV infected people on ART and data was entered into a computer software Microsoft excel, then imported to Stata 12 for analysis.

Discussion

The overall prevalence of overweight at the initiation of ART amongst the participants was 18.1% and obesity was 11.5% as compared to the time of the study which was 21.4% overweight and 19.6% obese. The average time of ART initiation to study period was 3.6 years. The study findings revealed a significant difference (p-value 0.006) between the baseline and current body mass index at time of study for females. Hypertension was found to be having a significant difference (p-value 0.026 and 0.038) between the baseline and current body mass index at time of study for males and females respectively. The overall prevalence of hypertension was found to be 34.6%, overweight was 21.4% obesity was 19.6%.

The overall prevalence of abnormal waist circumference was 31.9% and females had a higher prevalence of 42.5% as compared to 4.4% of males. The overall prevalence of smoking 10.8% and alcohol consumption was 21.7%. Males were 22.5 times more likely to be smokers than females (p < 0.001) and older people were found to be 0.3 times less likely to consume alcohol as compared to young people.

Conclusions

The high levels of selected risk factors for NCDs among adults on ART in the current study area suggest an urgent need for health interventions to control risk factors in an era of HIV with an aim of reducing multiple morbidity of chronic diseases. Occurrence of NCDs and their risk factors with an aim to achieve positive effects of the long-term ART.

Are birthweight and postnatal weight gain in childhood associated with blood pressure in early adolescence? Results from a Ugandan birth cohort

BACKGROUND

In Africa, where low birthweight (LBW), malnutrition and high blood pressure (BP) are prevalent, the relationships between birthweight (BW), weight gain and BP later in life remain uncertain. We examined the effects of early life growth on BP among Ugandan adolescents.

METHODS

Data were collected prenatally from women and their offspring were followed from birth, with BP measured following standard protocols in early adolescence. Weight-for-age Z-scores (WAZ) were computed using World Health Organization references. Linear regression was used to relate BW, and changes in WAZ between birth and 5 years, to adolescents' BP, adjusting for confounders.

RESULTS

Among 2345 live offspring, BP was measured in 1119 (47.7%) adolescents, with mean systolic BP 105.9 mmHg and mean diastolic BP 65.2 mmHg. There was little evidence of association between BW and systolic [regression coefficient β = 0.14, 95% confidence interval (CI) (-1.00, 1.27)] or diastolic [β = 0.43, 95% CI (-0.57, 1.43)] BP. Accelerated weight gain between birth and 5 years was associated with increased BP: systolic β = 1.17, 95% CI (0.69, 1.66) and diastolic β = 1.03, 95% CI (0.59, 1.47). Between birth and 6 months of age, effects of accelerated weight gain on adolescent BP were strongest among the LBW (both premature and small-for-gestational-age) children [BW < 2.5 kg: β = 2.64, 95% CI (0.91, 4.37), BW≥2.5 kg: β = 0.58, 95% CI (0.01, 1.14), interaction P-value =  0.024].

CONCLUSIONS

Findings from this large tropical birth cohort in Uganda suggest that postnatal weight gain rather than BW is important in the developmental programming of BP, with fast-growing LBW children at particular risk. Efforts to control BP should adopt a life course approach.

Chronic Diseases Multimorbidity among Adult People Living with HIV at Hawassa University Comprehensive Specialized Hospital, Southern Ethiopia

Background

Due to the wide implementation of antiretroviral therapy (ART), people living with HIV (PLWHIV) are now living longer. This increased the risk of developing noncommunicable chronic diseases (NCCDs) among them.

Objective

We aimed to describe prevalence of NCCDs multimorbidity among PLWHIV at Hawassa University Comprehensive Specialized Hospital (HUCSH).

Method

In April 2016, institution-based cross-sectional study was conducted among PLWHIV, aged ≥ 18 years at the ART unit of HUCSH. A nurse working in the ART unit interviewed patients and reviewed medical records. Data on the NCCDs and its risk factors were obtained. List of diseases considered in this study were arthritis, diabetes mellitus, hypertension, congestive heart failure (CHF), rheumatic heart diseases (RHD), chronic bronchitis, asthma, and cancer.

Results

More than half of the respondents (196) had at least one of the NCCDs and 34 (8.9%) had multimorbidity. The main system of the body affected were the musculoskeletal system, 146 (38.2%) and respiratory system, 46 (12.0%). There was no significant difference in the prevalence of individual NCCDs by gender. Patients aged above 44 years, patients with ART duration of at least 6 years, and patients with higher CD4 counts had increased odds of having any one of the NCCDs. Multimorbidity patients with a longer ART duration had an increased risk.

Conclusion

The prevalence of NCCD multimorbidity among PLWHIV was high. Monitoring the occurrence of NCCDs among PLWHIV and noncommunicable disease care is recommended.

Assessing Providers' Approach to Hypertension Management at a Large, Private Hospital in Kampala, Uganda

Background:

Hypertension is increasingly prevalent in Uganda and its clinical management remains suboptimal across the country. Prior research has elucidated some of the factors contributing to poor control, but little is known about providers’ approaches to hypertension management and perceptions of barriers to care. This is particularly true in private health care settings – despite the fact that the private sector provides a substantial and growing portion of health care in Uganda.

Objective:

Our exploratory, pragmatic qualitative study aimed to examine the factors affecting the quality of hypertension care from the perspective of providers working in an urban, private hospital in Uganda. We focused on the organizational and system-level factors influencing providers’ approaches to management in the outpatient setting.

Methods:

We conducted interviews with 19 health care providers working in the outpatient setting of a 110-bed, private urban hospital in Kampala, Uganda. We then coded the interviews for thematic analysis, using an inductive approach to generate the study’s findings.

Findings:

Several themes emerged around perceived barriers and facilitators to care. Providers cited patient beliefs and behaviors, driven in part by cultural norms, as a key challenge to hypertension control; however, most felt their own approach to hypertension treatment aligned with international guidelines. Providers struggled to collaborate with colleagues in coordinating the joint management of patients. Furthermore, they cited the high cost and limited availability of medication as barriers.

Conclusions:

These findings offer important strategic direction for intervention development specific to this Ugandan context: for example, regarding culturally-adapted patient education initiatives, or programs to improve access to essential medications. Other settings facing similar challenges scaling up management of hypertension may find the results useful for informing intervention development as well.

Prevalence and sex-specific patterns of metabolic syndrome in rural Uganda

Background and aims

In sub-Saharan Africa, infectious diseases are still the leading causes of mortality; however, this may soon be surpassed by non-communicable illnesses, namely hypertension, diabetes and cardiovascular disease. This study determined the prevalence and patterns of metabolic syndrome and cardio-risk factors in men and women in rural Uganda.

Methods

A household-based, cross-sectional survey was carried out following the WHO STEP-wise approach to surveillance. It included demographic and lifestyle questionnaires, anthropometric measurements and biochemical analyses. Of the 200 randomly recruited participants, 183 successfully completed two steps of the study and 161 provided blood samples.

Results

Data were collected from 183 adults, aged 18–69 years; 62% were female. Based on the National Cholesterol Education Program-Adult Treatment Panel-III criteria, the prevalence of metabolic syndrome was 19.1% (95% CI 14.0 to 22.5). Elevated fasting plasma glucose was observed in 14.2% (95% CI 9.1 to 19.3) of participants, hypertriglyceridaemia in 16.9% (95% CI 12.1 to 23.1); hypertension in 36.1% (95% CI 29.0 to 43.0) and 52.5% (95% CI 45.2 to 59.6) had low HDL (high-density lipoprotein) cholesterol. Abdominal obesity was found in 24.6% (95% CI 18.8 to 31.4) of participants. Sex disparities were significant for several risk factors. Females had significantly higher prevalence of abdominal obesity (38.6% vs 1.5% in males, p=0.001) and twice the rates of low HDL (65.8% vs 30.4%, p=0.001). Men tended to have higher but not significant rates of hypertension (42.0% vs 32.5%) and smoked significantly more than women (49.3% vs 21.1%, p<0.001). Alcohol consumption was also higher in men (55.1% vs 18.4%, p<0.001) and quantities consumed were approximately three times greater than in females (p<0.001).

Conclusion

Metabolic syndrome exists at worrying rates in the rural Ugandan population. Sex disparities are evident in risk factor prevalence, reflecting physiological variables and deeply entrenched cultural and lifestyle norms.

"We shall have gone to a higher standard": Training village heath teams (VHTs) to use a smartphone-guided intervention to link older Ugandans with hypertension and diabetes to care

Background: It is not clear whether village health teams (VHTs) can be empowered to participate in interventions to prevent and control hypertension and diabetes in older adults in Uganda. We conducted this study in rural Uganda to establish the experiences of VHTs in managing older adults with health problems, their knowledge of hypertension and diabetes and their understanding of referral systems. We also explored their experiences with smartphones and whether VHTs could be effectively trained to use a smartphone-guided intervention to link older adults with hypertension and diabetes mellitus to care. Methods: We conducted in-depth interviews (IDIs) with and trained 20 VHTs randomly selected from Bukulula sub-county in Kalungu district from October 2017-December 2018. We used interview guides to explore topics relevant to our study objectives. VHTs were trained to measure blood sugar and blood pressure using digital machines. VHTs were trained on identifying symptoms of diabetes mellitus. Data from IDIs were analysed using thematic content analysis. Competence tests were used to evaluate the training. Results: Most of the VHTs were female (75%). All VHTs had some knowledge on hypertension and diabetes and other chronic diseases. They did not have any experience in treating older adults since they had been trained to deal mainly with children. Half of the VHTs owned smartphones. All were willing to participate in an intervention using a smartphone to link older adults with hypertension and diabetes mellitus to care. By the end of the training, all but three participants could comprehend the symptoms of diabetes and measure blood sugar and blood pressure. Conclusion: Village health teams in the study setting need training in managing the health needs of older adults before engaging with an intervention using smartphones to link older adults with diabetes mellitus and hypertension to care.

Validity of Anthropometric Cut-Offs for Early Diagnosis of Dyslipidemia Among Ethiopian Adults

INTRODUCTION

Lack of regional- and local-based cut-off points of lipid profile and/or anthropometric measurements remains one of the challenges in prevention, early detection and control of non-communicable diseases. This study aimed to validate anthropometric-based screening of lipid profiles to develop locally appropriate optimal cut-off points for metabolic syndrome screening.

METHODS

A community-based cross-sectional study was conducted among randomly selected 977 adults in Jimma Town, Ethiopia. Data were collected using structured questionnaire, anthropometric and biochemical measurements. Data were analyzed using SPSS windows version 21 and Kappa statistic was used to validate the agreement between anthropometric measurement and lipid profile. A p-value of <0.05 was considered statistically significant.

RESULTS

Body mass index (BMI) at ≥24.5 was used as screening of dyslipidemia (TG≥150mg/dl) with slight Kappa coefficient of 0.138 (P<0.001) among females while it was ≥22.2 among males with fair (0.275) Kappa coefficient (P<0.001). Waist circumference-based screening of dyslipidemia (TG≥150mg/dl) at ≥78.0cm had negative (-0.005) Kappa coefficient (Pp<0.001) among females (sensitivity: 72.6% and specificity: 26.7%). Yet, waist circumference at ≥83.7cm had slight Kappa coefficient of 0.13 (P<0.005) among males (sensitivity: 38% and specificity: 74.9%). Waist hip ratio-based screening of dyslipidemia (TG≥150mg/dl) at ≥0.82 among females had negative (-0.001) Kappa coefficient (p=0.763), whereas among males at ≥0.88, there was a slight (0.105) Kappa coefficient of (p=0.002) (sensitivity:77.5% and specificity:36.8%). This study showed that anthropometric-based high-density lipoprotein measurement was not applicable.

CONCLUSION

This study indicated that BMI-based screening of triglyceride was more applicable for both sexes than other anthropometric measurements. Waist circumference and waist-to-hip ratio-based screening of triglyceride were slightly applicable only for males. However, anthropometric-based screening of high-density lipoprotein measurement was not applicable for both sexes. In conclusion, researchers and policy makers need to consider locally validated cut-off points to be used for screening metabolic syndrome in the community.

Dyslipidemias and cardiovascular risk scores in urban and rural populations in north-western Tanzania and southern Uganda

BACKGROUND

Dyslipidemia is a leading risk factor for atherosclerotic cardiovascular disease. There are few published epidemiological data regarding dyslipidemia in Africa. We determined full lipid and apolipoprotein profiles and investigated factors associated with lipid levels in urban and rural populations of north-western Tanzania and southern Uganda.

METHODS

We conducted a cross-sectional survey of randomly-selected, community-dwelling adults (≥18yrs) including five strata per country: one municipality, two district towns and two rural areas. Participants were interviewed and examined using the World Health Organization STEPwise survey questionnaire. Serum levels of total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides, and apolipoproteins were measured. Factors associated with mean lipid levels were assessed by multivariable linear regression. Framingham 10-year cardiovascular risk scores were calculated with and without lipids.

RESULTS

One-third of adults in the study population had dyslipidemia. Low high-density lipoprotein cholesterol affected 32-45% of rural adults. High total cholesterol, low-density lipoprotein cholesterol, and apolipoprotein B were found in <15% of adult population in all strata, but were more common in urban adults. Factors independently associated with higher mean low-density lipoprotein cholesterol and apolipoprotein B were female gender, older age, higher education, higher income, obesity, and hypertension. Framingham cardiovascular risk scores with and without lipids yielded similar results and 90% of study subjects in all strata were classified as "low risk". Among older adults (>55 years), 30% were classified as "high" or "very high" risk.

CONCLUSIONS

Dyslipidemias are common among adults in north-western Tanzania and southern Uganda affecting one third of adult population. Overall, cardiovascular risk scores are low but high risk scores are common with older adults. Health services designed and equipped to diagnose and treat dyslipidemia are urgently needed.

Prevalence and Predictors of Obesity among 7- to 17-Year-Old Schoolchildren in Urban Arusha, Tanzania

BACKGROUND

Childhood obesity is currently increasing at an alarming rate worldwide. Childhood obesity research has not been reported in urban Arusha before. This is therefore the first study to investigate the prevalence and predictors of childhood obesity in urban Arusha.

METHODS

A cross-sectional study was conducted involving 451 schoolchildren. Overweight was defined to range from 85th to 94th BMI percentile for age and sex while obesity was defined as above 94th BMI percentile for age and sex. Chi-square test was used for comparison between child sex and sociobehaviors, and multiple logistic regression was used to determine the significant predictor factors at P values = 0.05.

RESULTS

The overall prevalence of overweight and obesity was 17.7% (80/451) with 12.6% (57/451) being obese and 5.1% (23/451) being overweight. Results from univariate logistic regression showed child sex, random sleeping time, and random eating habit were the significant predictor factors. However, when all the predictor factors were used in the final multiple logistic regression model, only random sleeping time and random eating habit of different food items irrespective of their nature were significant at P=0.000, AOR = 4.47, and 95% CI = 2.00-10.01, and P=0.012, AOR = 2.54, and 95% CI = 1.23-5.33, respectively.

CONCLUSIONS

The prevalence of obesity was as higher as twice the prevalence observed in other previous studies in Tanzania. Being a girl, random sleeping time and random eating habit were independent predictors. In addition to larger sample sizes, longitudinal studies are needed in order to track individuals and population level trends in BMI over time.

Modern contraceptive use among sexually active women aged 15-19 years in North-Western Tanzania: results from the Adolescent 360 (A360) baseline survey

OBJECTIVES

To describe differences in modern contraceptive use among adolescent women aged 15-19 years according to their marital status and to determine factors associated with modern contraceptive use among sexually active women in this population.

DESIGN

Cross-sectional analysis of Adolescent 360 evaluation baseline survey.

SETTING

The 15 urban and semiurban wards of Ilemela district, Mwanza region, North-Western Tanzania.

PARTICIPANTS

Adolescent women aged 15-19 years who were living in the study site from August 2017 to February 2018 and who provided informed consent. Women were classified as married if they had a husband or were living as married. Unmarried women were classified as sexually active if they reported having sexual intercourse in the last 12 months.

OUTCOME MEASURE

Prevalence of modern contraceptive among adolescent women aged 15-19 years.

RESULTS

Data were available for 3511 women aged 15-19 years, of which 201 (5.7%) were married and 744 (22.5%) were unmarried-sexually active. We found strong evidence of differences in use of modern contraceptive methods according to marital status of adolescent women. Determinants of modern contraception use among unmarried-sexually active women were increasing age, increasing level of education, being in education, hearing of modern contraception from interpersonal sources or in the media in the last 12 months, perceiving partner and/or friends support for contraceptive use, as well as higher knowledge and self efficacy for contraception.

CONCLUSIONS

Sexual and reproductive health programmes aiming to increase uptake of modern contraceptives in this population of adolescent women should consider the importance of girl's education and social support for contraceptive use particularly among unmarried-sexually active women.

Prevalence of non-communicable diseases among HIV positive patients on antiretroviral therapy at joint clinical research centre, Lubowa, Uganda

Introduction

Antiretroviral therapy (ART) has changed the course of HIV/AIDs by enabling patients to live longer, raising concern of the co- existence of HIV with other chronic illnesses, notably non-communicable diseases (NCDs). NCDs are on the rise in developing countries and evidence shows higher occurrence among people living with HIV (PLHIV). In Uganda, the burden of NCDs among PLHIV remains largely unquantified.

Objective

To determine the prevalence of hypertension, osteoporosis, diabetes mellitus, renal impairment, asthma, cardiomyopathy and multi-morbidity among HIV positive patients, receiving Anti-Retroviral Therapy at Joint Clinical Research Centre, Lubowa, Uganda.

Methods

This was a cross-sectional study conducted among 387 systematically sampled patients, receiving ART at the Joint Clinical Research Centre, Lubowa, between March and April 2017. The study used data extracted from routine care patient files to identify individuals with non-communicable diseases. Prevalence of the NCDs was estimated and reported with 95% confidence intervals. Prevalence was also reported at various levels of socio- demographic, behavioural and clinical factors.

Results

The overall prevalence of having at least one NCD was 20.7% (95% CI: 16.7–24.5). The prevalence of hypertension was 12.4% (95% CI: 9.1–15.7), osteoporosis 6.5% (95% CI: 4.0–8.9), diabetes mellitus 4.7% (95% CI: 2.6–6.8), renal impairment 1.6% (95% CI: 0.3–2.8), asthma 1.6% (95% CI: 0.3–2.8), and cardiomyopathy 1.3% (95% CI: 0.2–2.4). Prevalence of multi-morbidity was 4.7% (95% CI: 2.6–6.8). Prevalence was significantly higher among older participants, widowed participants and individuals with an opportunistic infection.

Conclusion

Non-communicable diseases are common among people living with HIV. There is need to encourage early diagnosis and treatment of non-communicable diseases in PLHIV in Uganda.

Role of Noncommunicable Diseases (NCDs) in Resource-Limited Settings (RLS)

PURPOSE OF REVIEW

As access to effective antiretroviral therapy (ART) expands globally, a decline in AIDS-related morbidity and mortality has been complicated by rising rates of noncommunicable diseases (NCDs). This review provides a brief description of NCDs and existing gaps on knowledge about NCDs among HIV-infected adults mostly in Africa.

RECENT FINDINGS

Recent reports show that one in every five persons living with HIV has a chronic illness, predominantly diabetes and/or hypertension, depression, and most of these conditions are either not diagnosed or not being managed. Human papilloma virus-associated anal dysplasia occurs among 70% of HIV-infected women in RLS. Recognizing risk factors for NCDs and providing effective screening and optimal care remains challenging. Research is urgently needed to carefully characterize HIV-associated NCDs in RLS. Such studies should provide a framework for high-priority NCDs that the limited resources can be focused on in these settings.

Noncommunicable disease burden among HIV patients in care: a national retrospective longitudinal analysis of HIV-treatment outcomes in Kenya, 2003-2013

BACKGROUND

Over the last decade, the Kenyan HIV treatment program has grown exponentially, with improved survival among people living with HIV (PLHIV). In the same period, noncommunicable diseases (NCDs) have become a leading contributor to disease burden. We sought to characterize the burden of four major NCDs (cardiovascular diseases, cancer, chronic respiratory diseases and diabetes mellitus) among adult PLHIV in Kenya.

METHODS

We conducted a nationally representative retrospective medical chart review of HIV-infected adults aged ≥15 years enrolled in HIV care in Kenya from October 1, 2003 through September 30, 2013. We estimated proportions of four NCD categories among PLHIV at enrollment into HIV care, and during subsequent HIV care visits. We compared proportions and assessed distributions of co-morbidities using the Chi-Square test. We calculated NCD incidence rates and their confidence intervals in assessing cofactors for developing NCDs.

RESULTS

We analyzed 3170 records of HIV-infected patients; 2115 (66.3%) were from women. Slightly over half (51.1%) of patient records were from PLHIVs aged above 35 years. Close to two-thirds (63.9%) of PLHIVs were on ART. Proportion of any documented NCD among PLHIV was 11.5% (95% confidence interval [CI] 9.3, 14.1), with elevated blood pressure as the most common NCD 343 (87.5%) among PLHIV with a diagnosed NCD. Despite this observation, only 17 (4.9%) patients had a corresponding documented diagnosis of hypertension in their medical record. Overall NCD incidence rates for men and women were (42.3 per 1000 person years [95% CI 35.8, 50.1] and 31.6 [95% CI 27.7, 36.1], respectively. Compared to women, the incidence rate ratio for men developing an NCD was 1.3 [95% CI 1.1, 1.7], p = 0.0082). No differences in NCD incidence rates were seen by marital or employment status. At one year of follow up 43.8% of PLHIV not on ART had been diagnosed with an NCD compared to 3.7% of patients on ART; at five years the proportions with a diagnosed NCD were 88.8 and 39.2% (p < 0.001), respectively.  CONCLUSIONS: PLHIV in Kenya have a high prevalence of NCD diagnoses. In the absence of systematic, effective screening, NCD burden is likely underestimated in this population. Systematic screening and treatment for NCDs using standard guidelines should be integrated into HIV care and treatment programs in sub-Saharan Africa.

Prevalence of high blood pressure and associated factors among adolescents and young people in Tanzania and Uganda

We conducted a cross-sectional study among school/college students in Tanzania and Uganda to determine the prevalence of high blood pressure (BP) and associated factors. Participants were classified to have high BP if they had pre-hypertension or hypertension. Interviews were done using the WHO STEPS instrument. Using data from both countries (n = 1596), the overall prevalence of high BP was 40% (95% CI: 37-42). The prevalence of pre-hypertension was 29% (95% CI: 26-31) and that of hypertension was 11% (95% CI: 10-13). High BP was independently associated with obesity (aOR = 6.7, 95% CI: 2.2-20.0), male sex (aOR = 3.2, 95% CI: 2.4-4.4), and among males aged above 20 years (aOR = 5.5, 95% CI: 2.9-10.5). Consumption of fruits/vegetables was associated with decreased odds for high BP (aOR = 0.7, 95% CI: 0.50-0.98). The increasing burden of pre-hypertension across age groups could explain the early onset of hypertension and cardiovascular diseases (CVDs) among young African adults. There is a need for longitudinal studies to explore the drivers of pre-hypertension in East African adolescents.

Hypertension prevalence and risk factors among residents of four slum communities: population-representative findings from Port-au-Prince, Haiti

OBJECTIVES

The aim of this study was to estimate the prevalence of hypertension and its risk factors among adults in four slum communities in Port-au-Prince.

METHODS

Cluster area random sampling was used to select adults for a health and demographic survey, including anthropometric measurements. Hypertension was defined as SBP at least 140 mmHg and/or DBP at least 90 mmHg, or current hypertension treatment, and was age-standardized to WHO world population. Correlates of hypertension were tested using sex-stratified logistic regression.

RESULTS

Overall, 20.3% of adults had hypertension (28.5% age-standardized), including 22.3% of men and 18.9% of women. Three percent of participants reported current hypertension treatment, and 49.5% of them had their hypertension controlled. Overweight/obesity (BMI ≥25) was the most common risk factor (20.6% among men, 48.5% among women), while smoking was less common (11.8 and 3.9%, respectively). Increasing age and hypertension prevalence in immediate surroundings were associated with greater odds of hypertension. Among men, having in-migrated in the 3 years prior (versus ≥3 years) was also associated with hypertension [adjusted odds ratio (aOR)=3.32, 95% confidence interval (95% CI): 1.79-6.17], as was overweight and obesity (aOR = 1.90, 95% CI: 1.09-3.33, and aOR = 5.73, 95% CI: 2.49-13.19, respectively) and nonreceipt of needed medical care in the preceding 6 months (aOR = 2.82, 95% CI: 1.35-5.88) among women.

CONCLUSION

Hypertension prevalence was high across the age spectrum, in addition to substantial levels of overweight/obesity and unmet healthcare needs. It is important to better understand the possible effects of intraurban migration and environmental risk factors on hypertension and ensure that the benefits of increasingly cost-effective prevention and treatment programmes extend to slum residents.

Active smoking among people with diabetes mellitus or hypertension in Africa: a systematic review and meta-analysis

The objective was to summarize existing data on the prevalence of active tobacco smoking among patients with hypertension or diabetes mellitus in Africa. We searched PubMed, EMBASE, and AJOL to include studies published from January 01, 2000 to August 23, 2017 reporting on the prevalence of active smoking in individuals aged ≥15 years with hypertension or diabetes mellitus residing inside Africa. We used a random-effects meta-analysis model to pool studies. The pooled prevalence of active smoking among patients with hypertension or diabetes was 12.9% (95%CI: 10.6–15.3; 50 studies; 16,980 patients) and 12.9% (95%CI: 9.6–16.6; 42 studies; 18,564 patients), respectively. For both conditions, the prevalence of active smoking was higher in males than in females (p < 0.001), and in Northern compared to sub-Saharan Africa (p < 0.001). There was no difference between urban and rural settings, and between community-based and hospital-based studies, except for patients with diabetes for whom the prevalence was higher in hospital-based studies (p = 0.032). The prevalence of active smoking is high among patients with hypertension or diabetes mellitus in Africa, with the heaviest burden in Northern Africa. Interventions for smoking prevention or cessation should be implemented in these high risk populations, targeting particularly the males.

Prevalence, Patterns, and Factors Associated with Peripheral Neuropathies among Diabetic Patients at Tertiary Hospital in the Kilimanjaro Region: Descriptive Cross-Sectional Study from North-Eastern Tanzania

OBJECTIVE

Diabetic peripheral neuropathy (DPN) is a common microvascular complication of diabetes mellitus (DM) and may progress to diabetic foot, which frequently leads to amputation and/or disability and death. Data is scanty on the burden of diabetic peripheral neuropathy in Tanzania. The aim of this study was to assess the burden of peripheral neuropathy, its severity, and the associated factors.

METHODS

The study was a cross-sectional hospital-based study and was carried out from October 2017 to March 2018 among adolescent and adult patients attending Kilimanjaro Christian Medical Center (KCMC) diabetes clinic.

RESULTS

A total of 327 diabetic patients, females n=215 (65.7%) and males n=121 (34.3%), were included in the study. The mean age was 57.2 yrs. A total of 238 (72%) had type 2 and 89 (27.2%) had type1 DM. The prevalence of peripheral neuropathy was 72.2% of whom 55% were severe, 19% were moderate, and 26% were mild. The severity of neuropathy increased with the increase in age >40 years (p < 0.001) and increase in body mass index (p<0.001) and duration of diabetes; duration >7 years (p <0.006). The main associated factors were age >40 years, OR 2.8 (1.0-7.7), >60 years, OR 6.4 (2.3-18.2), obesity, OR 6.7 (0.9-27.7), and hypertension, OR 4.3 (2.2-8.2).

CONCLUSION

More than half of the patients included in this study were found to have neuropathy, nearly half of whom presented with the severe form. The main risk factors were increasing age, increasing duration of diabetes, obesity, and hypertension. Diabetic peripheral neuropathy is underdiagnosed in northern Tanzania where screening for neuropathy is not routinely done.

Doye I, Toure M, Sy MP, Kiviat NB, Sow PS, Gottlieb GS, Hawes SE. Increasing prevalence of hypertension among HIV-positive and negative adults in Senegal, West Africa, 1994-2015

BACKGROUND

Non-communicable diseases, including hypertension (HTN), are increasingly recognized as important causes of morbidity and mortality among people living with HIV (PLHIV) in resource-limited settings. The goals of this study were to determine the prevalence of HTN among PLHIV in Senegal over time and to identify predictors of HTN among HIV-positive versus HIV-negative adults.

METHODS

We conducted a retrospective study using data from individuals enrolled in previous studies in Senegal from 1994-2015. Blood pressure (BP) measurements taken during study visits were used for analysis. HTN was defined as systolic BP≥140 or diastolic BP≥90. We used logistic regression to identify predictors of HTN.

RESULTS

We analyzed data from 2848 adults (1687 HIV-positive, 1161 HIV-negative). Among PLHIV, the prevalence of HTN increased from 11% during 1994-1999 to 22% during 2010-2015. Among HIV-negative individuals, the prevalence of HTN increased from 16% to 32%. Among both groups, the odds of HTN more than doubled from 1994-1999 to 2010-2015 (HIV-positive OR 2·4, 95% CI 1·1-5·0; HIV-negative OR 2·6, 95% CI 1·5-4·6). One quarter of all individuals with HTN had stage 2 HTN. The strongest risk factor for HTN was obesity (HIV-positive OR 3·2, 95% CI 1·7-5·8; p<0·01; HIV-negative OR 7·8, 95% CI 4·5-13·6; p<0·01). Male sex and age ≥50 were also predictive of HTN among both groups. Among HIV-positive subjects, WHO stage 1 or 2 disease was predictive of HTN and among HIV-negative subjects, having no formal education was predictive.

CONCLUSION

Over the past 20 years, the prevalence of HTN has doubled among both HIV-positive and HIV-negative adults in Senegal. Our study indicates that there is an increasing need for the integration of chronic disease management into HIV programs in Senegal. Furthermore, our findings highlight the need for enhanced prevention, recognition, and management of non-communicable diseases, including hypertension and obesity, among both HIV-positive and HIV-negative individuals in Senegal.

Patterns of non-communicable disease and injury risk factors in Kenyan adult population: a cluster analysis

BACKGROUND

Non-communicable diseases and unintentional injuries are emerging public health problems in sub-Saharan Africa. These threats have multiple risk factors with complex interactions. Though some studies have explored the magnitude and distribution of those risk factors in many populations in Kenya, an exploration of segmentation of population at a national level by risk profile, which is crucial for a differentiated approach, is currently lacking. The aim of this study was to examine patterns of non-communicable disease and injury risk through the identification of clusters and investigation of correlates of those clusters among Kenyan adult population.

METHODS

We used data from the 2015 STEPs survey of non-communicable disease risk factors conducted among 4484 adults aged between 18 and 69 years in Kenya. A total of 12 risk factors for NCDs and 9 factors for injury were used as clustering variables. A K-medians Cluster Analysis was applied. We used matching as the measure of the similarity/dissimilarity among the clustering variables. While clusters were described using the risk factors, the predictors of the clustering were investigated using multinomial logistic regression.

RESULTS

We have identified five clusters for NCDs and four clusters for injury based on the risk profile of the population. The NCD risk clusters were labelled as cluster hypertensives, harmful users, the hopefuls, the obese, and the fat lovers. The injury risk clusters were labelled as helmet users, jaywalkers, the defiant and the compliant. Among the possible predictors of clustering, age, gender, education and wealth index came out as strong predictors of the cluster variables.

CONCLUSION

This cluster analysis has identified important clusters of adult Kenyan population for non-communicable disease and injury risk profiles. Risk reduction interventions could consider these clusters as potential target in the development and segmentation of a differentiated approach.

Prevalence of arterial hypertension and risk factors among people with acquired immunodeficiency syndrome

OBJECTIVES

to verify the prevalence of arterial hypertension and its risk factors among people with acquired immunodeficiency syndrome under antiretroviral therapy.

METHOD

cross-sectional study with 208 patients. Data collection was conducted through interviews using a form containing data on sociodemographic, clinical and epidemiological aspects, hypertension risk factors, blood pressure, weight, height, body mass index and abdominal circumference. Mean, standard deviation, odds ratio and confidence interval were calculated, t-test and Chi-square test were used, considering P < 0.05 as statistically significant. Hypertension associated variables were selected for logistic regression.

RESULTS

patients were male (70.7%), self-reported as mixed-race (68.2%), had schooling between 9 and 12 years of study (46.6%), had no children (47.6%), were single (44.2%), in the sexual exposure category (72.1%) and heterosexual (60.6%). The prevalence of people with acquired immunodeficiency syndrome and arterial hypertension was 17.3%. Logistic regression confirmed the influence of age greater than 45 years, family history of hypertension, being overweight and antiretroviral therapy for more than 36 months for hypertension to occur.

CONCLUSION

the prevalence of hypertension was 17.3%. Patients with acquired immunodeficiency syndrome and hypertension were older than 45 years, had family history of hypertension, were overweight and under antiretroviral therapy for more than 36 months.

Models of integration of HIV and noncommunicable disease care in sub-Saharan Africa: lessons learned and evidence gaps

OBJECTIVE

To describe available models of HIV and noncommunicable disease (NCD) care integration in sub-Saharan Africa (SSA).

DESIGN

Narrative review of published articles describing various models of HIV and NCD care integration in SSA.

RESULTS

We identified five models of care integration across various SSA countries. These were integrated community-based screening for HIV and NCDs in the general population; screening for NCDs and NCD risk factors among HIV patients enrolled in care; integration of HIV and NCD care within clinics; differentiated care for patients with HIV and/or NCDs; and population healthcare for all. We illustrated these models with descriptive case studies highlighting the lessons learned and evidence gaps from the various models.

CONCLUSION

Leveraging existing HIV infrastructure for NCD care is feasible with various approaches possible depending on available program capacity. Process and clinical outcomes for existing models of care integration are not yet described but are urgently required to further advise policy decisions on HIV/NCD care integration.

Prevalence of CKD, Diabetes, and Hypertension in Rural Tanzania

INTRODUCTION

Chronic kidney disease (CKD), diabetes, and hypertension play a disproportionate role in the growing public health challenge posed by noncommunicable diseases (NCDs) in East Africa. The impact of these NCDs may pose the greatest challenge in rural areas with limited screening and treatment facilities, although precise prevalence estimates of these conditions in rural Tanzania are lacking.

METHODS

The prevalence of CKD, diabetes, and hypertension, were estimated from a probability sample of adults (n = 739) residing in 2 communities within Kisarawe, a rural district of Tanzania. Following consent, participants were studied in their homes. Random point-of-care (POC) measures of glycosylated hemoglobin and blood pressure, were obtained. Serum creatinine, drawn at the POC and measured at Muhimbili National University, was used to calculate estimated glomerular filtration rate with the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation.

RESULTS

The median age was 35 years (interquartile range 25-45 years). Overall the pooled prevalence for CKD stages III, IV, and V was 12.4% (95% confidence interval [CI] = 10.2-14.8). Surprisingly, the prevalence of CKD stage V (3.0%; 95% CI = 2.1-4.4) was high among the youngest age group (18-36 years). The prevalence estimates for prehypertension and hypertension were 38.0% (95% CI = 34.6-41.5) and 19.9% (95% CI = 17.1-22.9), respectively. The prevalence estimates for prediabetes and diabetes were 25.7% (95% CI = 22.6-29.1) and 14.8% (95% CI = 12.4-17.6), respectively.

CONCLUSION

Although this pilot study had a relatively small sample size, the prevalence estimates for CKD, diabetes, and hypertension were higher than we expected based on previous estimates from Tanzania. CKD was not significantly associated with diabetes or hypertension, suggesting the possibility of an alternative causality.

Hypertension prevalence and risk factors in rural and urban Zambian adults in western province: a cross-sectional study

Introduction

Hypertension is a longstanding problem in Zambia, yet little is known about its prevalence and risk factors, particularly in rural and urban settings. Identifying geographical variations in hypertension is important to enhance the health of adult Zambians regardless of where they live. Therefore, the purpose of this study was to compare the prevalence of hypertension and related risk factors between rural (n = 130) and urban (n = 131) communities in Western Province, Zambia.

Methods

This cross-sectional study included urban and rural adult Zambians attending health checks who completed a modified World Health Organization (WHO) survey, and had blood pressure and anthropometric measurements completed. Descriptive statistics were used to summarize demographic and risk factor variables. Chi-square tests of association were used to analyze relationships between categorical variables, t-tests to analyze relationships between continuous variables and logistic regression to examine associations of hypertension with selected risk factors.

Results

The prevalence of hypertension in rural Zambians was double (46.9%) that of urban Zambians (22.9%). Increasing age, not engaging in walking/biking, and alcohol intake within the last 30 days were associated with an increased likelihood of hypertension in rural Zambians while eating vegetables more days during the week was associated with a decreased likelihood of hypertension in rural Zambians. Body Mass Index (BMI) was significantly associated with an increased likelihood of hypertension in urban Zambians.

Conclusion

Modifiable risk factors (such as BMI, dietary intake, and physical activity) are associated with hypertension prevalence in this population, indicating opportunities for screening and other prevention measures.

Evaluating the impact of an intervention to increase uptake of modern contraceptives among adolescent girls (15-19 years) in Nigeria, Ethiopia and Tanzania: the Adolescents 360 quasi-experimental study protocol

INTRODUCTION

Nigeria, Ethiopia and Tanzania have some of the highest teenage pregnancy rates and lowest rates of modern contraceptive use among adolescents. The transdisciplinary Adolescents 360 (A360) initiative being rolled out across these three countries uses human-centred design to create context-specific multicomponent interventions with the aim of increasing voluntary modern contraceptive use among girls aged 15-19 years.

METHODS

The primary objective of the outcome evaluation is to assess the impact of A360 on the modern contraceptive prevalence rate (mCPR) among sexually active girls aged 15-19 years. A360 targets different subpopulations of adolescent girls in the three countries. In Northern Nigeria and Ethiopia, the study population is married girls aged 15-19 years. In Southern Nigeria, the study population is unmarried girls aged 15-19 years. In Tanzania, both married and unmarried girls aged 15-19 years will be included in the study. In all settings, we will use a prepopulation and postpopulation-based cross-sectional survey design. In Nigeria, the study design will also include a comparison group. A one-stage sampling design will be used in Nigeria and Ethiopia. A two-stage sampling design will be used in Tanzania. Questionnaires will be administered face-to-face by female interviewers aged between 18 and 26 years. Study outcomes will be assessed before the start of A360 implementation in late 2017 and approximately 24 months after implementation in late 2019.

ETHICS AND DISSEMINATION

Findings of this study will be widely disseminated through workshops, conference presentations, reports, briefings, factsheets and academic publications.

Sociodemographic Characteristics and Health Profile of the Elderly Seeking Health Care in Kampala, Uganda

Aging entails health challenges globally, but pertinent data from low-income countries like Uganda remains scarce. A cross-sectional study was carried out at Mulago National Referral Hospital in Kampala, among 134 patients (38% men and 62% women) aged ≥60 years. Data was collected on sociodemographic characteristics, medical disorders, cognitive function, hearing handicap, and functional status, that is, Basic Activities of Daily Living (BADL) and Instrumental Activities of Daily Living (IADL). The participants had high independency in BADL (89%) and IADL (75%). The most common medical conditions were bone/joint pain (35%), hypertension (24%), and visual problems (20%). More women (54%) than men (37%) reported bone and joint pain. The majority (80%) of the participants did not report any hearing handicap, and half (54%) did not have any cognitive impairment. Dependency in IADL was associated with advanced age, being female, and being financially dependent, and the risk of having a hearing handicap was higher among those above the median age (68 years). In adjusted models, the effects remained similar although statistical significance was only achieved for advanced age versus dependency in IADL (RR: 2.38, 95% CI: 1.12-5.08) and hearing handicap (RR: 2.67, 95% CI: 1.17-6.12). Thus, socioeconomic status and gender are relevant aspects when attempting to understand the health profile of the elderly in Kampala, Uganda.

Sedentary Lifestyle and Hypertension in a Periurban Area of Mbarara, South Western Uganda: A Population Based Cross Sectional Survey

Introduction

Globally, cardiovascular diseases (CVDs) and diabetes constitute over 50% of the noncommunicable disease (NCD) burden and projections indicate Sub-Saharan Africa will experience a larger burden. Urbanization on the continent is contributing to the change in lifestyle such as diet and physical activity, which may increase the risk for CVDs. There is lack of sufficient data from the African continent on hypertension and its association with sedentary lifestyle.

Methods

We conducted a cross sectional study in periurban Uganda among adults aged at least 35 years. We administered questions on diet, physical activity, and smoking. We took anthropometric measurements, blood pressure, and fasting blood glucose. Hypertension was defined as systolic BP > = 140 and/or diastolic BP > = 90 and/or history of hypertension medications. Logistic regression was used to determine the crude and adjusted odds ratios for the factors associated with hypertension.

Results

We enrolled 310 participants and 50% were female. The prevalence of systolic hypertension was 24.5%, diastolic hypertension was 31%, obesity was 46%, and diabetes was 9%. Of those with hypertension (n = 76), 53 participants (69.7%) were not aware they had high BP. Sedentary lifestyle was significantly associated with hypertension even after adjusting for age and obesity.

Conclusion

There is a high prevalence of obesity, hypertension, and diabetes and majority of participants with hypertension are not aware. Participants with a sedentary work style should be targeted for prevention and screening.

Hypertension among newly diagnosed diabetic patients at Mulago National Referral Hospital in Uganda: a cross sectional study

BACKGROUND

The prevalence of hypertension in patients with diabetes is approximately two-fold higher than in age-matched subjects without the disease and, conversely, individuals with hypertension are at increased risk of developing diabetes compared with normotensive persons. Up to 75% of cases of cardiovascular disease (CVD) in patients with diabetes are attributed to hypertension. Diabetics who have hypertension are more likely to develop complications and die, and appropriate blood pressure control in these individuals reduces the risk. This study sought to determine the prevalence and factors associated with hypertension among newly diagnosed adult diabetic patients in a national referral hospital in Uganda.

METHODS

In this cross-sectional study, conducted between June 2014 and January 2015, we recruited 201 newly diagnosed adult diabetic patients. Information on patients' socio-demographics was obtained using a pre-tested questionnaire, while biophysical profile, blood pressure measurement, biochemical testing and echocardiographic findings were obtained by the research team for all the participants. Bivariate and multivariate logistic regression analyses were used to investigate the association of several factors with hypertension.

RESULTS

Of the 201 patients recruited, 102 were male (50.8%) and the mean age was 46 ± 15 years. The majority of patients (159) had type 2 diabetes mellitus (DM) (79.1%) with a mean HbA1c level of 13.9 ± 5.3%. The prevalence of hypertension was 61.9% (95% CI: 54.8-68.6%). Knowledge of hypertension status was at 56 (27.7%) patients, 24 (44.4%) hypertensives were on treatment, and 19 (33.9%) were using ACE inhibitors/angiotensin receptor blockers. The independent factors associated with hypertension were being employed (OR 0.37, 95% CI: 0.16-0.90, p = 0.029) and being overweight or obese (OR 11.6, 95% CI: 4.29-31.2, p < 0.0001).

CONCLUSION

The prevalence of hypertension was high in this population of newly diagnosed diabetics, few patients had knowledge of their hypertension status and few were on appropriate treatment. Both modifiable and non-modifiable risk factors were associated with hypertension in this group. Therefore routine assessment, treatment and control of hypertension among diabetics is necessary to prevent cardiovascular complications and death. There is also a need to address the modifiable risk factors.

The prevalence of alcohol dependence and its association with hypertension: a population-based cross-sectional study4 in Xuzhou city, China

Background

To describe the prevalence of alcohol dependence and to explore the relationship between alcohol dependence and newly detected hypertension in China.

Methods

A multistage stratified cluster sampling method was used to obtain samples from February to June 2013. The Michigan Alcoholism Screening Test was used to estimate alcohol dependence level. A standard questionnaire measured other independent variables. Enumeration data were analyzed using chi-square; quantitative data were analyzed using t-tests. Spearman correlation analysis and multivariate logistic regression analysis were performed to identify the relationship between alcohol dependence and hypertension.

Results

The alcohol dependence rate was 11.56%; 22.02% of males (3854/17501) and 1.74% of females (324/18656) were classified as alcohol dependent. The newly detected hypertension rate was 9.46% (3422/36157). Significant associations were found between alcohol dependence levels and blood pressure (P < 0.01). Alcohol dependence was positively correlated with systolic blood pressure (r = 0.071, P < 0.01) and diastolic blood pressure (r = 0.077, P < 0.01) and was an independent risk factor for hypertension after adjusting for confounders (low alcohol dependence: odds ratio [OR] = 1.44, 95% confidence intervals [CI] = 1.14–1.81, P < 0.01; light alcohol dependence: OR = 1.35, 95% CI = 1.11–1.64, P < 0.01; medium alcohol dependence: OR = 1.83, 95% CI = 1.40–2.41, P < 0.01).

Conclusion

Alcohol dependence was high and associated with hypertension. Health education and precautions against alcoholism should be implemented in Xuzhou city.

Alcohol consumption among tobacco farmers: prevalence and associated factors

RESULTS

This study aims to describe the prevalence of heavy drinking, high-risk alcohol consumption and associated factors among tobacco farmers. A cross-sectional study was carried out with 2,469 tobacco farmers over 18 years old in 2011. High-risk alcohol consumption was considered the intake of three or more standard doses per day for men or two or more for women. Heavy drinking was considered the intake of four or more standard doses per day for men and three or more for women. Hierarchical multivariate analysis was performed to investigate the association with socioeconomic, behavioral, and occupational variables. : The prevalence of high-risk and heavy drinking was of 4.7% and 1.09% among women and 30.8% and 4.8% among men, respectively. The factors associated with high-risk drinking for men and women were the percentage of income tobacco accounted for (PR 1.3 and 0.4), being an employee (PR 1.3 and 3.1), and use of pesticides (PR 1.5 and 2.1), respectively. Heavy drinking among men was associated with losing the crop (PR 1.6), attending religious activities (PR 0.3), and hours working in agriculture (PR 0.6). Occupational factors were associated wit high-risk alcohol consumption among men. The associated factors vary according to the pattern of consumption assessed.

The unfunded priorities: an evaluation of priority setting for noncommunicable disease control in Uganda

BACKGROUND

The double burden of infectious diseases coupled with noncommunicable diseases poses unique challenges for priority setting and for achieving equitable action to address the major causes of disease burden in health systems already impacted by limited resources. Noncommunicable disease control is an important global health and development priority. However, there are challenges for translating this global priority into local priorities and action. The aim of this study was to evaluate the influence of national, sub-national and global factors on priority setting for noncommunicable disease control in Uganda and examine the extent to which priority setting was successful.

METHODS

A mixed methods design that used the Kapiriri & Martin framework for evaluating priority setting in low income countries. The evaluation period was 2005-2015. Data collection included a document review (policy documents (n = 19); meeting minutes (n = 28)), media analysis (n = 114) and stakeholder interviews (n = 9). Data were analysed according to the Kapiriri & Martin (2010) framework.

RESULTS

Priority setting for noncommunicable diseases was not entirely fair nor successful. While there were explicit processes that incorporated relevant criteria, evidence and wide stakeholder involvement, these criteria were not used systematically or consistently in the contemplation of noncommunicable diseases. There were insufficient resources for noncommunicable diseases, despite being a priority area. There were weaknesses in the priority setting institutions, and insufficient mechanisms to ensure accountability for decision-making. Priority setting was influenced by the priorities of major stakeholders (i.e. development assistance partners) which were not always aligned with national priorities. There were major delays in the implementation of noncommunicable disease-related priorities and in many cases, a failure to implement.

CONCLUSIONS

This evaluation revealed the challenges that low income countries are grappling with in prioritizing noncommunicable diseases in the context of a double disease burden with limited resources. Strengthening local capacity for priority setting would help to support the development of sustainable and implementable noncommunicable disease-related priorities. Global support (i.e. aid) to low income countries for noncommunicable diseases must also catch up to align with NCDs as a global health priority.

Preparedness of lower-level health facilities and the associated factors for the outpatient primary care of hypertension: Evidence from Tanzanian national survey

INTRODUCTION

Sub-Saharan Africa is experiencing a rapid rise in the burden of non-communicable diseases in both urban and rural areas. Data on health system preparedness to manage hypertension and other non-communicable diseases remains scarce. This study aimed to assess the preparedness of lower-level health facilities for outpatient primary care of hypertension in Tanzania.

METHODS

This study used data from the 2014-2015 Tanzania Service Provision Assessment survey. The facility was considered as prepared for the outpatient primary care of hypertension if reported at least half (≥50%) of the items listed from each of the three domains (staff training and guideline, basic diagnostic equipment, and basic medicines) as identified by World Health Organization-Service Availability and Readiness Assessment manual. Data were analyzed using Stata 14. An unadjusted logistic regression model was used to assess the association between outcome and explanatory variables. All variables with a P value < 0.2 were fitted into the multiple logistic regression models using a 5% significance level.

RESULTS

Out of 725 health facilities involved in the current study, about 68% were public facilities and 73% located in rural settings. Only 28% of the assessed facilities were considered prepared for the outpatient primary care of hypertension. About 9% and 42% of the assessed facilities reported to have at least one trained staff and guidelines for hypertension respectively. In multivariate analysis, private facilities [AOR = 2.7, 95% CI; 1.2-6.1], urban location [AOR = 2.2, 95% CI; 1.2-4.2], health centers [AOR = 5.2, 95% CI; 3.1-8.7] and the performance of routine management meetings [AOR = 2.6, 95% CI; 1.1-5.9] were significantly associated with preparedness for the outpatient primary care of hypertension.

CONCLUSION

The primary healthcare system in Tanzania is not adequately equipped to cope with the increasing burden of hypertension and other non-communicable diseases. Rural location, public ownership, and absence of routine management meetings were associated with being not prepared. There is a need to strengthen the primary healthcare system in Tanzania for better management of chronic diseases and curb their rising impact on health outcomes.

Is birth weight associated with blood pressure among African children and adolescents? A systematic review

There is substantial evidence of an inverse association between birth weight and later blood pressure (BP) in populations from high-income countries, but whether this applies in low-income countries, where causes of low birth weight are different, is not certain.

OBJECTIVE

We conducted a review of the evidence on the relationship between birth weight and BP among African children and adolescents. Medline, EMBASE, Global Health and Web of Science databases were searched for publications to October 2016. Papers reporting the relationship between birth weight and BP among African children and adolescents were assessed. Bibliographies were searched for further relevant publications. Selected papers were summarized following the preferred reporting items for systematic review and meta-analysis (PRISMA) guidelines. In total, 16 papers from 13 studies conducted in nine African countries (Nigeria, Republic of Seychelles, Gambia, Democratic Republic of Congo, Cameroon, South Africa, Algeria, Zimbabwe and Angola) were reviewed. Eight studies were cohorts, while five were cross-sectional. The relationship between birth weight and later BP varied with age of the participants. Studies in neonates showed a consistently positive association, while predominantly inverse associations were seen among children, and studies in adolescents were inconsistent. Based on the limited number of studies identified, the relationship between birth weight and later BP may vary with age in African children and adolescents. Not all studies adequately controlled for confounding, notably gender or age. Whether the inverse relationship between birth weight and BP in later life observed in Western settings is also seen in Africa remains unclear.

High rates of hypertension, diabetes, elevated low-density lipoprotein cholesterol, and cardiovascular disease risk factors in HIV-infected patients in Malawi

OBJECTIVES

Data on cardiovascular disease risks among HIV-infected patients taking antiretroviral therapy (ART) over long periods of time are lacking in Sub-Saharan Africa.

METHODS

A cross-sectional study was conducted in Chiradzulu, Malawi from December 2015 to June 2016. HIV-infected persons on ART for more than 10 years (patients) and HIV-negative individuals (controls) from selected clinics participated. Following informed consent, a standardized questionnaire, clinical and laboratory examinations were performed. The prevalence of cardiovascular disease risk factors was calculated and stratified by age group.

RESULTS

Overall, 379 HIV-infected patients and 356 controls participated. Median time on ART among patients was 11.6 years (interquartile range 10.6-12.4).Within the 30-44, 45-59, and at least 60-year age groups, respectively, the prevalence of hypertension was 10.8, 20.4, and 44.7% among patients and 6.1, 25.8, and 42.9% among controls. Hypertension was previously undiagnosed in 60.3% patients and 37.0% controls with elevated blood pressure. The prevalence of diabetes within the respective age groups was 5.0, 6.4, and 13.2% among patients, and 3.4, 4.2, and 1.7% among controls. HIV-infected patients were more likely to have an glycated hemoglobin at least 6.0% (adjusted odds ratio 1.9; 95% confidence interval 1.1-3.2, P = 0.02). Prevalence of low-density lipoprotein cholesterol more than 130 mg/dl within the respective age groups was 8.0, 15.4, and 23.7% among patients and 1.8, 12.5, and 11.8% among controls.

CONCLUSION

Noncommunicable diseases were a significant burden in Malawi, with high prevalence of hypercholesterolemia in all survey participants and an especially acute diabetes burden among older HIV infected. Hypertension screening and treatment services are needed among identified high-risk groups to cover unmet needs.
