Hypertension and Associated Factors in Rural and Urban Areas Mali: Data from the STEP 2013 Survey

Background. Our study aims to estimate hypertension (HTN) prevalence and its predictors in rural and urban area. Methods. We conducted a cross-sectional population-based study involving subjects aged 15 to 65 years. Collected data (sociodemographic, blood pressure, weight, height, and blood glucose) were analyzed using SPSS version 20. A logistic regression was conducted to look for factors associated with HTN. Results. Mean was 47 years. High blood pressure (HBP) prevalence was 21.1 and 24.7%, respectively, in rural and urban setting. In rural area age group significantly predicted hypertension with age of 60 years having more-than-4-times risk of hypertension, whereas, in urban area age group, sex and body mass index were predictors with OR: HTN raising from 2.06 [1.24-3.43] for 30-44 years old to 7.25 [4.00-13.13] for 60 years and more using < 30 years as reference. Female sex was protective with OR of 0.45 [0.29-0.71] and using normal weight as reference OR for overweight was 1.54 [1.04-2.27] and 2.67 [1.64-4.36] for obesity. Conclusion. Hypertension prevalence is high and associated factors were age group in rural area and age group, female sex, and body mass index in urban area.
