Self-reported gender differentials in the knowledge of tuberculosis transmission and curative possibility using national representative data in Ghana

An insight from National Family Health Surveys on changing trends in prevalence and knowledge regarding T.B. in India

BACKGROUND/OBJECTIVES

Addressing gaps in knowledge about T.B. is a vital component of T.B.'s elimination to achieve the End T.B. strategy by 2025 in India. The present study compares the correct knowledge regarding T.B. by analysis of the nationally-representative secondary data of NFHS-4 (2015-16) and NFHS-5 (2019-20) data in India.

METHODS

NFHS-4 and NFHS-5 secondary data on eleven T.B.-related questions analysis was done after seeking permission to use datasets from the Demographic and Health Surveys (DHS) program-sociodemographic details and Responses exported and analysed using M.S. Excel. Descriptive variables were represented as frequency and percentages. Z tests for proportions were used to compare and determine differences between NFHS-4 and NFHS-5 knowledge. Statistical significance was set at a p-value of <0.05.

RESULTS

The correct knowledge regarding T.B. significantly rose from 457,399 (56.3%) in NFHS-4 to 507,517 (61.4%) in NFHS-5. However, a significant increase in incorrect knowledge about the other modes of transmission of T.B. and T.B. courtesy stigma in households from 95,985 (13.4%) in 2015-16 to 113,978 (14.9%) in 2019-20 was observed.

CONCLUSIONS

The correct knowledge of T.B. has significantly increased from NFHS-4 (2015-16) to NFHS-5 (2019-20). However, there is a significant increase in incorrect knowledge regarding the modes of transmission and stigmatising attitudes towards T.B. through improvement in the communication efforts in the National T.B. Elimination Programme (NTEP).

Comparison of microscopic and xpert MTB diagnoses of presumptive mycobacteria tuberculosis infection: retrospective analysis of routine diagnosis at Cape Coast Teaching Hospital

INTRODUCTION

Tuberculosis is a global health problem that causes 1. 4 million deaths every year. It has been estimated that sputum smear-negative diagnosis but culture-positive pulmonary TB diagnosis contribute to 12.6% of pulmonary TB transmission. TB diagnosis by smear microscopy smear has a minimum detection limit (LOD) of 5,000 to 10,000 bacilli per milliliter (CFU/ml) of sputum result in missed cases and false positives. However, GeneXpert technology, with a LOD of 131-250 CFU/ml in sputum samples and its implementation is believe to facilitate early detection TB and drug-resistant TB case. Since 2013, Ghana health Service (GHS) introduce GeneXpert MTB/RIF diagnostic in all regional hospitals in Ghana, however no assessment of performance between microscopy and GeneXpert TB diagnosis cross the health facilities has been reported. The study compared the results of routine diagnoses of TB by microscopy and Xpert MTB from 2016 to 2020 at the Cape Coast Teaching Hospital (CCTH).

METHODS

The study compared routine microscopic and GeneXpert TB diagnosis results at the Cape Coast Teaching Hospital (CCTH) from 2016 to 2020 retrospectively. Briefly, sputum specimens were collected into 20 mL sterile screw-capped containers for each case of suspected TB infection and processed within 24 h. The samples were decontaminated using the NALC-NaOH method with the final NaOH concentration of 1%. The supernatants were discarded after the centrifuge and the remaining pellets dissolved in 1-1.5 ml of phosphate buffer saline (PBS) and used for diagnosis. A fixed smears were Ziehl-Neelsen acid-fast stain and observed under microscope and the remainings were used for GeneXpert MTB/RIF diagnosis. The data were analyze using GraphPad Prism.

RESULTS

50.11% (48.48-51.38%) were females with an odd ratio (95% CI) of 1.004 (0.944-1.069) more likely to report to the TB clinic for suspected TB diagnosis. The smear-positive cases for the first sputum were 6.6% (5.98-7.25%), and the second sputum was 6.07% (5.45-6.73%). The Xpert MTB-RIF diagnosis detected 2.93% (10/341) (1.42-5.33%) in the first and 5.44% (16/294) (3.14-8.69%) in the second smear-negative TB samples. The prevalence of Xpert MTB-RIF across smear positive showed that males had 56.87% (178/313) and 56.15% (137/244) and females had 43.13% (135/313) and 43.85% (107/244) for the first and second sputum. Also, false negative smears were 0.18% (10/5607) for smear 1 and 0.31% (16/5126) for smear 2.

CONCLUSION

In conclusion, the study highlights the higher sensitivity of the GeneXpert assay compared to traditional smear microscopy for detecting MTB. The GeneXpert assay identified 10 and 16 positive MTB from smear 1 and smear 2 samples which were microscopic negative.

Knowledge, Attitudes, and Preventive Practices Regarding Tuberculosis Among Healthcare Workers and Patients in India: A Mixed-Method Study

BACKGROUND

Tuberculosis (TB) remains a major public health challenge in India. Healthcare workers (HCWs) and TB patients are critical to disease transmission and prevention. This study evaluated and compared knowledge, attitudes, and practices related to TB infection control.

MATERIALS AND METHODS

This was a mixed-method study that included a cross-sectional survey conducted among 167 HCWs and 346 patients with TB at tertiary hospitals in western Gujarat using a validated questionnaire. Additionally, 20 HCWs and 20 patients were interviewed to gain qualitative insights. Between-group analyses were performed, and multivariate regressions identified predictors of knowledge and compliance, while thematic analysis explored qualitative insights.

RESULTS

A total of 142/167 (85.0%) HCWs had good knowledge, whereas 208/346 (60.1%) patients had good knowledge. A total of 151/167 (90.4%) HCWs had positive attitudes, whereas 242/346 (69.9%) patients had positive attitudes. A total of 159/167 (95.2%) HCWs practiced good preventive behaviors, whereas 225/346 (65.0%) patients did. HCWs demonstrated significantly higher mean knowledge scores (9.2 vs. 7.1, p<0.001) and higher median attitude scores (ranging from 5 with IQR 4-5 to 5 with IQR 5-5) compared to patients (ranging from 4 with IQR 3-5 to 5 with IQR 4-5) across all attitude statements assessed using the Likert scale (p<0.001). Being an HCW was associated with good knowledge (adjusted odds ratio (AOR) 2.5, 95% CI 1.5-4.1), positive attitudes (AOR 2.2, 95% CI 1.4-3.6), and good practices (AOR 3.1, 95% CI 1.8-5.2). The qualitative themes highlighted the need for accessible education, clear communication, adequate resourcing, and personal responsibility.

CONCLUSION

This study identified gaps in TB prevention knowledge and practices among patients compared to those among HCWs in India. Tailored educational initiatives, optimized health communication, improved infrastructure, and accessible messaging can help individuals assimilate appropriate infection control behaviors among healthcare system actors and communities toward ending TB.

Determinants of intention to conceal tuberculosis status among family members: an analysis of seven Sub-Saharan African countries

BACKGROUND

Tuberculosis (TB) remains a significant public health burden in Sub-Saharan Africa (SSA), accounting for about 25% of global TB cases. In several communities, TB diagnosis, treatment, and control have become a critical challenge, largely due to the intention to conceal TB status among family members. It is therefore crucial to understand the factors associated with the intentions to conceal TB status among family members in SSA.

METHODS

This quantitative study utilised data from the most recent Demographic and Health Surveys (DHS). The objective was to examine the factors associated with the intention to conceal the TB status of family members. The sample consisted of 58,849 individuals aged 10 years or older from seven SSA countries. Binary logistic regression was employed to assess the associations between TB status concealment and various socio-demographic and economic variables.

RESULTS

The overall prevalence of TB status concealment intentions for the seven countries was 28.0% (95% CI: 27.6-28.4). Malawi and Eswatini accounted for the highest (47.3%) and lowest (3.0%) prevalence of TB concealment intentions respectively. TB status concealment intentions decreased with increasing age (p < 0.001). Living in rural areas was associated with lower odds of intending to conceal the TB of family members compared to living in urban areas (aOR = 0.92; p = 0.008). Higher education levels were associated with lower odds of TB status concealment intentions (aOR = 0.50; p < 0.001) compared to lower education levels. As participants wealth index increased, the odds of TB status concealment intentions decreased (aOR = 0.83; p < 0.001). Country of residence also showed significant associations with individuals in Ghana (aOR = 4.51; p < 0.001), Lesotho (aOR = 2.08; p < 0.001), Malawi (aOR = 4.10; p < 0.001), Namibia (aOR = 4.40; p < 0.001), and Sao-Tome and Principe (aOR = 5.56; p < 0.001) showing higher odds of TB status concealment intentions compared to Eswatini.

CONCLUSIONS

The findings conclude that several social determinants of health, including age, urbanicity, education, and wealth contribute to TB status concealment intentions for family members. Considering these factors is important for designing targeted interventions to improve TB control in the sample. In light of the unavailability of cultural variables in the dataset, future research can leverage qualitative approaches to conduct a more comprehensive exploration of the cultural factors linked to TB status concealment intentions in the population.

Sociocultural understanding of Tuberculosis and implications for care-seeking among adults in the province of Zambezia, Mozambique: Qualitative research

INTRODUCTION

Mozambique has a high burden of Tuberculosis (TB) with an incidence of 368 per 100,000 population in 2020, coupled with a low all-form TB detection rate. The COVID-19 pandemic has exacerbated delays in timely diagnosis and treatment of new TB cases. Promoting active TB case finding is a national priority in Mozambique. We conducted qualitative research to explore factors influencing TB testing in Zambezia province in Mozambique.

MATERIALS AND METHODS

One-to-one, semi-structured, audio-recorded telephone interviews were conducted to explore TB-related knowledge, and barriers and facilitators to TB testing. A sample of two TB Program staff, two community providers of TB services, and 19 community members (10 women and 9 men) was recruited, with support from provincial government TB staff, from four districts in Zambezia with a high TB burden. Interviews were transcribed verbatim, and thematic analysis was conducted. The Mozambican National Bioethics Committee for Health approved the study protocol.

RESULTS

Our study highlights that knowledge about TB symptoms and its causes is low, which could delay timely TB testing. Sociocultural beliefs often implicate certain types of sexual activity and women as causes of TB symptoms; for example, having sex with a widow who has not been traditionally purified, or with a woman who has had an abortion. Therefore, people usually tend to first seek care from traditional healers instead of going to a health facility. Additionally, stigma associated with HIV and TB also delays care seeking. Gender-related disparities in TB care seeking were also evident.

CONCLUSIONS

This study provides valuable insights into how healthcare seeking for TB is influenced by sociocultural understanding of symptoms and gender dynamics. Therefore, interventions to promote timely and appropriate care seeking for TB should be contextually tailored, culturally appropriate, and gender sensitive.

Knowledge, Attitudes, and Perceptions of Tuberculosis in Indonesia: A Multi-Center Cross-Sectional Study

Introduction

Tuberculosis (TB) is still a persistent health challenge in Indonesia and ranks high on the list of factors causing morbidity and mortality. Improving knowledge, attitudes, and perceptions (KAP) of the general community about TB can help to control the disease.

Purpose

This study aimed to examine the KAP about TB in Indonesian society and investigate their sociodemographic determinants.

Participants and Methods

An online cross-sectional survey in 34 provinces in Indonesia was carried out in June 2022. The scores of KAP were classified as low, moderate, and high. Bivariate and multivariate ordinal logistic regression were applied to identify the potential sociodemographic determinants of KAP. Adjusted odds ratio and 95% confidence interval (CI) for each determinant were provided.

Results

Among the 3205 participants, 56.4%, 91%, and 38% had high scores on knowledge, attitude, and perception, respectively. Independent determinants of high knowledge were age (26-35 years; adjusted odds ratio: 1.53 [95% CI: 1.19-1.97]), marital status (married; adjusted odds ratio: 1.18 [95% CI: 1.00-1.39]), and salary (middle income; adjusted odds ratio: 0.76 [95% CI: 0.63-0.93]). Independent factors associated with high scores in attitude and perception were the residence location (village; adjusted odds ratio: 0.76 [95% CI: 0.59-0.98]) and the occupation type (civil servant; adjusted odds ratio: 1.53 [95% CI: 1.09-2.13]), respectively.

Conclusion

Most Indonesians have a high knowledge and good attitude, although they have a moderate perception toward TB. Improving public awareness and health education with the right strategies is critical to reducing the country's TB burden.

Assessing Oman's knowledge, attitude and practice regarding tuberculosis: a cross-sectional study that calls for action

BACKGROUND

Tuberculosis (TB) remains a major public health issue. Elimination mandates collaboration between decision makers, practitioners and the community. Few studies address the knowledge, attitude and practice (KAP) from countries with low incidence.

AIM

Assess KAP regarding TB in Oman.

METHOD

A cross-sectional survey based on validated questionnaire conducted via phone on randomly selected participants.

RESULTS

A total of 1048 participants completed the questionnaire. Males accounted for 63% (n=664) of respondents, Omanis 76% (n=796) and 18-39-year-olds 50% (n=527). The overall knowledge was fair (53%), overall attitude scored good and fair (46%) equally and a good score (78%) for overall practice. While female gender associated with higher knowledge (53.9%, n=201), males showed higher attitude and practice, (48.5%, n=322) and (80.3%, n=533) respectively. Omani nationality correlated with higher knowledge (49.1%, n= 391) and attitude (46.9%, n=373) whereas non-Omani nationality correlated with higher practice (85.3%, n=214). Literacy was associated with higher knowledge (73.3%, n=11) and attitude (60%, n=9).

CONCLUSION

Despite efforts by the Ministry of Health, more must be done to raise TB knowledge to encourage preferable attitudes and practice. Interventions to improve KAP are required to speed up disease reduction rate. Utilization of different resources, especially digital platforms, for knowledge dissemination should consider community diversity, including the presence of expatriates.
