Key result
Smoking is linked to ~4-fold higher odds of hypertension in rural Bangladeshi adults.
Why the study?
Riverine island populations face unique socio-environmental characteristics and restricted healthcare access, increasing vulnerability to hypertension and requiring targeted interventions.
Cross-Sectional (n=309)
No
In a riverine island population in Bangladesh, hypertension prevalence was high (41%) and strongly associated with modifiable lifestyle factors such as smoking, high salt and fat intake, and psychological stress.

High prevalence signals screening needs in isolated communities; smoking association is hypothesis-generating and requires prospective confirmation.
Background and Aims Assessing the prevalence of hypertension and associated determinants in riverine island populations is crucial due to their unique socio‐environmental characteristics and restricted healthcare access, which increase sensitivity to hypertension‐related problems and should lead targeted interventions. So, this study investigates the concerning issue of hypertension, focusing on its prevalence and influential factors among adults in Sirajganj's Riverine Island. Methods By employing a cross‐sectional approach, the research utilized a structured questionnaire. A total of 309 people took part in this study via face‐to‐face interviews by following convenience sampling technique. The investigators performed frequency analysis for getting prevalence of HTN and other variable's percentage and binary logistic regression analysis for getting associated determinants. Analysis was conducted by using a statistical package for social sciences (SPSS) version 25. Results The prevalence of hypertension was 41% among all individuals. People who were illiterate were 1.23 times more hypertensive. Some key risk factors were discovered, including smoking ( p = 0.04), adding salt to meals ( p < 0.001), eating fatty or fat‐type foods ( p < 0.001), sleeping late ( p < 0.001), worrying about their lifestyle and future ( p < 0.001), and not exercising ( p = 0.03). Males were 1.43 times more hypertensive (AOR = 1.43, 95% CI: 1.17−2.0, p = 0.002) than females. Smokers were 4.21 times more hypertensive (AOR = 4.21, 95% CI: 1.12−17.13, p = 0.04) than nonsmokers. Consumers oil/fat with food were 2.18 times more hypertensive (AOR = 2.18, 95% CI: 1.78−2.54, p < 0.001) than others. Respondents who were worried about their lifestyle and future were 3.38 times more hypertensive (AOR = 3.38, 95% CI: 1.27−6.01, p = 0.001) than others. Conclusion People should consume a healthy diet and refrain from smoking. Regular physical activity and going to bed early are recommended. Medical camps and workshops should be held on riverine islands to promote a healthy lifestyle and prevent hypertension.

Jamil et al. (2025) conducted a cross-sectional in Hypertension (n=309). Smoking vs. Nonsmokers was evaluated on Hypertension (AOR 4.21, 95% CI 1.12-17.13, p=0.04). Smoking significantly increased the odds of hypertension (AOR 4.21) among adults living in a riverine island in Bangladesh, where the overall prevalence of hypertension was 41%.
