BACKGROUND Due to epidemiological transitions, Sub-Saharan Africa is facing a growing burden of non-communicable diseases, including cardiovascular diseases (CVDs). Among their risk factors, hypertension is a major determinant of CVDs, but the prevalence and level of awareness and management of this condition are poorly studied in African populations. The aim of this study was to determine the prevalence of hypertension and identify its associated risk factors as well as the awareness and management of this condition in a community-dwelling cohort in Benin. METHODS A cross-sectional door-to-door study was conducted in the population over the age of 25 years in Tanve, a rural setting in Benin. The questionnaire and anthropometric measurements of the World Health Organization STEPWISE survey were used. Blood pressure was measured using standard procedures. RESULTS The sample included 1777 subjects (60.9% females, mean age was 42.5 ± 16.5 years). The prevalence of hypertension was 32.9%, similar in men (32.8%) and women (33.0%, p = 0.9342). Age and obesity were significantly associated with hypertension. Less than half (42%) of hypertensive people were aware about their condition and only 46.3% of them were treated. Awareness ratios differed between men and women (respectively 32.9% vs. 47.5%; p = 0.0039) and was not influenced by age, education, occupation, marital status or income. Female sex was the only factor associated with better controlled HTN, independent of socio-economic parameters. CONCLUSION This large population-based study confirms the high prevalence, low awareness, and low control of hypertension in men and women in sub-Saharan Africa. Only half of the populations with hypertension are aware of their hypertension, indicating a high burden of undiagnosed and un-controlled high blood pressure in these populations.

西非贝宁男性和女性高血压的患病率、认识、管理和控制：TAHES 研究。

背景由于流行病学的转变，撒哈拉以南非洲地区正面临着日益沉重的非传染性疾病负担，包括心血管疾病（CVD）。在其危险因素中，高血压是心血管疾病的主要决定因素，但在非洲人群中，对这种疾病的患病率、认识和管理水平的研究很少。本研究的目的是确定贝宁社区居住人群中高血压的患病率并确定其相关危险因素以及对这种情况的认识和管理。方法 对贝宁农村地区 Tanve 25 岁以上人群进行横断面挨家挨户研究。使用世界卫生组织STEPWISE调查的问卷和人体测量。使用标准程序测量血压。结果 样本包括 1777 名受试者（60.9% 为女性，平均年龄为 42.5 ± 16.5 岁）。高血压患病率为 32.9%，男性 (32.8%) 和女性 (33.0%，p = 0.9342) 相似。年龄和肥胖与高血压显着相关。不到一半 (42%) 的高血压患者了解自己的病情，并且只有 46.3% 的人接受了治疗。男性和女性的知晓率存在差异（分别为 32.9% 和 47.5%；p = 0.0039），并且不受年龄、教育、职业、婚姻状况或收入的影响。女性性别是与更好地控制高血压相关的唯一因素，与社会经济参数无关。结论 这项基于人群的大型研究证实了撒哈拉以南非洲地区男性和女性高血压的患病率高、知晓率低且控制率低。只有一半的高血压人群意识到自己患有高血压，这表明这些人群中未确诊和未控制的高血压负担很高。
