Key result
Blood pressure screening in Benin reveals ~35% hypertension prevalence with poor rates of control.
Why the study?
Hypertension is the strongest cardiovascular risk factor worldwide, and data on awareness, treatment, and control in Benin were needed to inform public health strategies.
What is the prevalence, awareness, treatment, and control of hypertension among adults in Benin?
Cross-Sectional (n=2,035)
Yes
What is the prevalence, awareness, treatment, and control of hypertension among adults in Benin?
Hypertension is highly prevalent in Benin with low rates of awareness, treatment, and control, highlighting the need for better detection and management strategies.
Documents low awareness and control of hypertension in Benin; leaves open whether targeted campaigns improve outcomes in similar settings.
Hypertension is the strongest cardiovascular risk factor worldwide. May Measurement Month (MMM) is an international campaign for blood pressure (BP) screening initiated by the International Society of Hypertension. This work aims to estimate the proportion and the levels of awareness, treatment, and control of hypertension in participants of the MMM survey in Benin in 2018. A cross-sectional survey focused on people aged ≥18 years was conducted in May 2018 in nine rural and urban areas in Benin. A sampling of volunteers was done. BP was measured following the MMM protocol. Hypertension was defined as a systolic BP ≥140 mm Hg and/or a diastolic BP ≥90 mm Hg (mean of the second and third readings) and/or taking antihypertensive medication. Linear regression was used to identify BP associations. A total of 2035 people were screened, including 55.9% women. The mean age was 44.2 ± 15.9 years. The percentage with hypertension was 35.4%. Of 721 participants with hypertension, 56.2% were aware of their diagnosis, 39.7% were on antihypertensive medication, and 13.6% were controlled (<140/90 mmHg). The results confirm the significant proportion of hypertension in Benin. Education programs on risk factors, early detection, and better management strategies should be developed.

Houéhanou et al. (2022) conducted a cross-sectional in Hypertension (n=2,035). Blood pressure screening was evaluated on Proportion of hypertension. Blood pressure screening in Benin identified a 35.4% prevalence of hypertension among 2,035 volunteers, of whom 56.2% were aware, 39.7% were treated, and 13.6% were controlled.
