Background: Hypertension is an increasing problem in South Asia, particularly Bangladesh. Although some epidemiological studies on hypertension have been conducted in Bangladesh, the prevalence and risk factors of hypertension in this nation remain unknown.

Objective: To determine the prevalence and risk factors of hypertension among adult population of Bangladesh.

Methods: We conducted a cross-sectional study using data from the nationally representative Bangladesh Demographic and Health Survey. Adults aged 35 years and older who participated in the survey were eligible for inclusion. Hypertension was defined by a systolic blood pressure (SBP) ≥ 140 mmHg, diastolic blood pressure (DBP) ≥ 90 mmHg, or receipt of an anti-hypertensive medication. Hypothesized factors associated with hypertension included age, gender, social status, place of residence and body mass index (BMI). Logistic regression models were used to determine the risk factors of hypertension.

Results: The prevalence of hypertension was 26.4% (Male-20.3%, Female-32.4%). Hypertension was significantly associated with age, education, social status place of residence (urban or rural), body mass index (BMI) and having diabetes. For example, the likelihood of hypertension was more than four times higher (OR= 4.24, 95% CI: 3.38-5.31) among the higher aged respondents 55-59 years compared to respondents age 35-39 years. Moreover, individuals from highest income (OR= 2.04, 95% CI: 1.63-2.54) and higher BMI (OR= 2.92, 95% CI: 2.10-4.04) had the maximum likelihood of having hypertension than the individuals with lowest income and normal BMI respectively.

Conclusions: The prevalence of hypertension is high (>26%) in Bangladesh. In this cross sectional study, increasing age, higher income, obesity were important factors of hypertension. Therefore, health education programmes for changing lifestyles to reduce the risk of hypertension is required in Bangladesh.
