Insights
Cardiovascular diseases (CVD) affect 4.5% of adults in Bangladesh, with hypertension and diabetes rising. Key risk factors include lifestyle and sociodemographic elements, necessitating urgent public health interventions.
Area of Science:
- Public Health
- Epidemiology
- Cardiology
Background:
- Cardiovascular diseases (CVD) pose a significant health challenge in Bangladesh.
- Rising prevalence necessitates understanding associated risk factors.
Purpose of the Study:
- To determine the prevalence of CVD in Bangladesh.
- To identify sociodemographic and lifestyle factors linked to CVD.
Main Methods:
- Cross-sectional survey of 12,338 adults (≥35 years) in rural and urban slum areas.
- Two-stage cluster random sampling with structured questionnaires and standardized measurements.
- Logistic regression analysis to explore associations with CVD.
Main Results:
- CVD prevalence was 4.5% (stroke 1.8%, heart diseases 3.2%).
- Significant risk factors included hypertension (30%), diabetes (5%), obesity (20%), tobacco use (77%), and physical inactivity (28%).
- Hypertension, diabetes, BMI, salt intake, sleep, tiredness, age, gender, occupation, region, and wealth quintile were associated with CVD.
Conclusions:
- CVD prevalence is high in Bangladesh, with increasing rates of hypertension and diabetes.
- Risk factors are prevalent across various sociodemographic groups, particularly older adults, women, and higher-income individuals.
- Urgent public health interventions are crucial to mitigate the growing CVD burden.
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.
