Determinants of correct knowledge on tuberculosis transmission and self-reported tuberculosis prevalence among general population aged 15–49 years in Myanmar

Abstract

Introduction Myanmar has been identified as one of the tuberculosis (TB) high-burden countries and having an understanding of TB transmission is vital for personal infection prevention as well as preventing transmission to others. This study aimed to identify the determinants of correct knowledge on TB transmission and self-reported TB prevalence among general population in Myanmar. Methods This is a cross-sectional study using secondary data from Myanmar demographic and health survey 2015–16. The determinants of correct knowledge on TB transmission mode and self-reported prevalence of TB were assessed using multivariable logistic regression models. Weighted estimates were provided in all analyses to account for the multistage sampling design used in the survey. Results Among the respondents, less than half (44.6%, 95% CI: 43.9, 45.4) had the overall correct knowledge about TB transmission and misconceptions. Older age group, female gender, those with higher education and higher socioeconomic status, and exposed to mass media at least once a week, residents from the delta and lowland region or plain areas were more likely to have correct knowledge about TB transmission. The overall prevalence rate of self-reported TB was 2.6% (95%CI: 2.4, 2.9) and the prevalence was higher among older age group and males. Conclusion Our study highlights the need for targeted efforts to improve awareness and understanding of TB transmission among general population in Myanmar. The study suggests the implementation of appropriate, innovative, and comprehensive targeted TB education and communication strategies.
