May Measurement Month 2019: an analysis of blood pressure screening results from Cameroon

Abstract

The multi-country May Measurement Month (MMM) screening campaign aims to raise awareness on blood pressure (BP) and hypertension in individuals and communities, and measure BP, ideally, of those who had no BP measurement in the preceding year. We here report key findings from the Cameroon arm of MMM 2019. An opportunistic sample of adults (≥18 years) was included from 5 May to 5 June 2019 across 15 sites (markets, churches, homes, motor parks, workplaces, and hospitals/clinics). Data collection, cleaning, the definition of hypertension, and statistical analysis followed the standard protocol. The mean age of the 30 187 participants screened was 36.9 (SD: 14.9) years, 50.4% were female (5% of whom were pregnant), and 94.4% were screened out of the hospital/clinic settings. After multiple imputation of missing data, 6286 (20.8%) had hypertension, 24.0% were taking antihypertensive medication, and 705 (11.2%) of all participants with hypertension had controlled BP. In linear regression models adjusted for age, sex, and antihypertensive medicines use, a previous diagnosis of hypertension, a history of stroke, and use of antihypertensive medicines were significant predictors of systolic and diastolic BP levels. BPs were also significantly higher when measured in public outdoors, public indoors (diastolic BP only), workplaces, and other unspecified areas compared to hospitals/clinic settings. MMM19 is the largest ever BP screening campaign in a single month, in Cameroon and despite the limitations resulting from non-random sample selection, the opportunistic screening allows access to awareness and screening for hypertension out of the hospital/clinic settings.

Care Cascades for Hypertension in Low-Income Settings: A Systematic Review and Meta-Analysis

“…Although we did not conduct a temporal analysis due to insufficient data, it is worth noting that since 2015, some countries have shown signs of improvement in terms of awareness, treatment, and control of hypertension. These positive changes may be attributed to local advocacy efforts and awareness campaigns, highlighting the potential for enhanced hypertension care even in resource-constrained settings [ 43 , 44 ].…”

Management of arterial hypertension: Challenges and opportunities

“…28 Real-life examples such as the "May Measurement Month" (MMM), an initiative led by the International Society of Hypertension and endorsed by the World Hypertension League and WHF, is an annual globally synchronized BP screening campaign designed primarily to raise awareness of the importance of BP measurement at the population level and in the process, detect untreated or inadequately treat HTN. 29 One critical finding of MMM in 2019 was that nearly one third of the screeners had never had their BP measured previously. 29…”

Suboptimal Target Blood Pressure Control and Its Association With the Sociodemographic and Clinical Profiles of Hypertensives Attending a Tertiary Level Hospital in Addis Ababa, Ethiopia

“…The prevalence of hypertension (HTN) is high with approximately 1.3 billion of the world's adult population affected [1] and is estimated to exceed 1.5 billion by 2025 [2,3]. Although the prevalence of HTN is slightly decreasing in high-income countries (HICs) with an estimated 349 million people, in contrast, it is rapidly increasing in low and middle-income countries (LMICs) with an estimated 1.04 billion people living with it currently [2].…”
