Prevalence and risk factors of cardiovascular diseases among Bangladeshi adults: Findings from a cross-sectional study

Abstract

Ever rising prevalence of Cardiovascular Diseases (CVD) is a major challenge for the health sector in Bangladesh. This study aimed to explore the prevalence of CVD and sociodemographic and lifestyle factors associated with it in Bangladesh. The data were collected through a cross-sectional survey following a two-stage cluster random sampling procedure. The present analysis was performed among 12,338 respondents aged ≥35 years, selected from rural areas and urban slums. Information was gathered using a structured questionnaire, whereas measurements were taken using standardized procedures. Logistic regression with exchangeable correlation structure among clusters was executed to explore the association. About 30% of participants had hypertension, 5% diabetes, 20% obesity; 77% were either smokers or consumed smokeless tobacco, and 28% were physically inactive. The prevalence of CVD was 4.5% (stroke: 1.8% and heart diseases: 3.2%). After adjusting for potential confounders, hypertension, diabetes, body mass index, extra salt intake, daily sleep, tiredness, age, gender, occupation, administrative division, and wealth quintile were found to be significantly associated with CVD. The study highlighted that the prevalence of CVD is high in Bangladesh, and its associated risk factors such as hypertension and diabetes are on the rise, especially in the older population, women, and high-income groups. Therefore, immediate public health intervention is warranted to address the issue.
