Abstract: Objectives: We investigated the prevalence, awareness, treatment, and control of hypertension and associated risk factors in the Bangladeshi adult population. Methods: The data for this study were extracted from the nationally-representative 2011 Bangladesh Demographic and Health Survey. Socio-demographic profiles, height, weight, blood pressure measurements, and management were recorded from 7876 adults aged 35 years or older. Multilevel logistic regression models were used to identify the risk factors for hypertension awareness, treatment, and control. Results: Overall, age-standardized prevalence of prehypertension and hypertension were 27.1 and 24.4%, respectively. Among patients with hypertension, 50.1% were aware of their condition, 41.2% were in treatment, but only 31.4% had controlled hypertension. There was a wide disparity in hypertension management between the poor and the wealthy households. Rich households were more likely to be aware of their hypertension [odds ratio (OR) 1.92, 95% confidence interval (CI) 0.97–3.79, P = 0.06], receiving treatment (OR 3.34, 95% CI 1.55–7.18, P < 0.001) and controlling their condition (OR 2.88, 95% CI 1.28–6.46, P = 0.01), as compared to the poor residents. Participants who had lower education were less likely to be aware of, in treatment for, and in control of their condition. Conclusion: One in four adults had hypertension in Bangladesh, and awareness and treatment of hypertension are quite low. Improvements in detection and treatment strategies are needed to prevent the growing disease burden associated with hypertension.
