May Measurement Month 2023: results of an opportunistic blood pressure screening campaign in Benin

Key Result

Opportunistic blood pressure screening in Benin identified hypertension in 40.1% of 2,367 adults, of whom only 20.2% had controlled blood pressure.

Key Points

This research aims to assess the awareness and control of hypertension during the MMM campaign in Benin.
Convenience sampling of adults aged ≥18 years at 15 sites across Benin.
Three seated blood pressure readings taken per participant.
Multiple imputation used for estimating missing blood pressure data.
949 (40.1%) participants had hypertension.
Of those with hypertension, 591 (62.3%) were aware of their condition, and 528 (55.6%) were on treatment.
Controlled blood pressure was observed in 192 (36.4%) of those on medication, with only 20.2% of all hypertensive participants achieving controlled BP.

What is the prevalence, awareness, treatment, and control of hypertension among adults screened during the May Measurement Month 2023 campaign in Benin?

Population

2,367 adults aged ≥18 years in Benin underwent opportunistic blood pressure screening to assess hypertension prevalence, awareness, and control.

Exposure

Opportunistic blood pressure screening (May Measurement Month campaign)

Outcome

Prevalence, awareness, treatment, and control of hypertension

The May Measurement Month 2023 campaign in Benin revealed a high prevalence of hypertension (40.1%) with low rates of adequate control (20.2%), highlighting the need for improved detection and management.

Abstract

Abstract The May Measurement Month (MMM) campaign was conducted in Benin in 2023 to raise awareness of raised blood pressure (BP). This article reports the results of the campaign. Adults aged ≥18 years were recruited through convenience sampling at 15 sites across nine urban, semi-urban, and rural communes. Three seated BP readings were taken on each participant, and a questionnaire collected information on demographics, lifestyle factors, and comorbidities. Hypertension was defined as a systolic BP ≥140mmHg and/or diastolic BP ≥90mmHg, or being on BP-lowering medication. Controlled BP was defined as being on BP-lowering medication with a BP 140/90mmHg. Multiple imputation was used to estimate missing BP readings. In total, 2,367 were screened, with a mean age of 44.0 years and 55.2% were female. Of all participants, 949 (40.1%) had hypertension, of whom 591 (62.3%) were aware, and 528 (55.6%) were on antihypertensive medication. Of those on antihypertensive medication, 192 (36.4%) had controlled BP, and of all participants with hypertension, 20.2% had controlled BP. The MMM campaign in Benin identified a substantial number of participants with untreated or inadequately treated hypertension. Measures must be taken to strengthen the prevention, detection and control of hypertension among Beninese adults.
