Hypertension increases risk of stroke and other cardiovascular diseases, however, its prevalence and determinants in South Asian urban communities using country representative community-based datasets is lacking. This study evaluated prevalence of hypertension and it’s determinants among urban residents of three South Asian countries. Urban population data from demographic and health surveys in Bangladesh, India, and Nepal were extracted. Hypertension prevalence was defined as systolic/diastolic blood pressure \(\ge\)140/ 90 mmHg. Age, education, wealth, physical activity, alcohol, BMI were considered as risk factors associated with the increased risk of hypertension. We performed binary logistic regression and calculated adjusted Odds Ratios (AOR) with 95% confidence interval (CI) to assess factors related to hypertension. Hypertension prevalence was 37.4% in India, 25.1% in Bangladesh and 18.4% in Nepal. Prevalence increased with age in all settings. Females had reduced odds of hypertension in Bangladesh (AOR 0.75; CI: 0.69, 0.81) and Nepal (AOR 0.62; CI: 0.54, 0.71), but higher risk in India (AOR 2.54; CI: 2.45, 2.63). Low education, caffeine consumption, obesity was associated with higher prevalence of hypertension in all three countries. Smokers had increased odds of hypertension in India (AOR 1.11; CI: 1.06, 1.15) and Nepal (AOR 1.23; 1.02, 1.47). Overall, hypertension prevalence is high in all three countries. Modifiable socioeconomic and lifestyle factors (education, wealth index, smoking status, caffeine consumption and BMI) associated with hypertension. Comprehensive hypertension pacific and sensitive interventions (including behavioral modification treatments and timely screening and access to health care) are urgently needed to prevent and control hypertension among urban populations in South Asia.

高血压会增加中风和其他心血管疾病的风险，然而，缺乏使用国家代表性社区数据集在南亚城市社区中的患病率和决定因素。本研究评估了三个南亚国家城市居民的高血压患病率及其决定因素。从孟加拉国、印度和尼泊尔的人口和健康调查中提取了城市人口数据。高血压患病率定义为收缩压/舒张压\(\ge\) 140/ 90 mmHg。年龄、教育程度、财富、体力活动、酒精、体重指数被认为是与高血压风险增加相关的危险因素。我们进行二元逻辑回归并计算调整后的优势比 (AOR) 和 95% 置信区间 (CI)，以评估与高血压相关的因素。印度的高血压患病率为 37.4%，孟加拉国为 25.1%，尼泊尔为 18.4%。在所有环境中，患病率随着年龄的增长而增加。孟加拉国（AOR 0.75；CI：0.69，0.81）和尼泊尔（AOR 0.62；CI：0.54，0.71）女性患高血压的几率较低，但印度的女性患高血压的风险较高（AOR 2.54；CI：2.45，2.63）。在这三个国家，教育程度低、咖啡因摄入量、肥胖与高血压患病率较高有关。印度（AOR 1.11；CI：1.06，1.15）和尼泊尔（AOR 1.23；1.02，1.47）吸烟者患高血压的几率增加。总体而言，这三个国家的高血压患病率都很高。与高血压相关的可改变的社会经济和生活方式因素（教育、财富指数、吸烟状况、咖啡因摄入量和体重指数）。迫切需要采取全面的高血压太平洋敏感干预措施（包括行为矫正治疗以及及时筛查和获得医疗保健）来预防和控制南亚城市人口的高血压。
