The prevalence of arterial hypertension in Morocco: Screening results from 'May Measurement Month' 2024

Abstract

Background: Arterial hypertension is the leading cause of mortality worldwide. The International Society of Hypertension initiated an annual global initiative called the May Measurement Month screening campaign to raise awareness regarding arterial hypertension and its adverse outcomes.

Aim: To evaluate the prevalence of arterial hypertension in Morocco, as well as the prevalence of uncontrolled and untreated hypertension.

Methods: Adult participants (≥18 years) were screened through opportunistic sampling across Morocco during May 2024. Trained volunteers recorded standardized blood pressure measurements, with the last two readings being averaged from community volunteer participants, along with socio-demographic parameters, weight, height, lifestyle factors, and comorbidities. Hypertension was defined as systolic blood pressure ≥ 140 mmHg and/or diastolic blood pressure ≥ 90 mmHg and/or taking antihypertensive medication.

Results: A total of 1421 participants were screened in May 2024, comprising 727 (51,2%) females and 694 (48,8%) males with a median age of 48 years (SD 20.1). Of all 1421 participants, 524 (36.9%) were hypertensive, while 52.9% were unaware of their hypertension status. Among participants who were previously diagnosed with hypertension, 79.4% were on antihypertensive medication, and only 45,9% had controlled hypertension.

Conclusion: Our study registered a high prevalence of arterial hypertension in Morocco. It also pointed to a high burden of undiagnosed and uncontrolled hypertension.
