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.

Background: Studies on financial aspects of High blood pressure management are rare and old without differentiating categories of expenses. On the other hand there is an evolution in health system with the introduction of a medical insurance. Objective: We performed this study to estimate costs related to insurance status. Methodology: The prospective study on patients aged 15 years and older extended from 01 May to 31 August 2016 and was carried out in the cardiology department of the University Hospital Gabriel Touré. Only newly detected or untreated hypertensive patients were included. Sociodemographic data, those on physical examination and financial management (transport, consultation, labor tests and purchase of drugs) were collected. Regarding costs, patients were directly asked about: how much did you spend for transport, consultation, labor tests and drugs? Data analysis was carried out by comparing patients with health insurance (Ins+) and those without it (Ins−). The recorded data were inserted in a MS Access database, preliminarily processed by MS Excel and imported to SPSS version 20 for analysis. Results: Mean total cost of care was 57,018 FCFA [50,139-63,897] (around 92 USD). It was 50,072 [42,182-57,963] for the Ins− group against 79,670 [66,777-92,563] for the Ins+ group with a p value < 0.0001. Highest amounts for spending were for cardiovascular medication and labor tests with means of 19,255 FCFA (32 USD) and 18,813 FCFA (30 USD). Mean consultation fee was significantly higher for Ins+ patients: 4064 FCFA with IC (95%) [3210-4917] versus 3124 with IC (95%)
