May Measurement Month 2021: an analysis of blood pressure screening results from Uganda

High blood pressure (BP) is the leading cause of cardiovascular disease in Uganda accounting for more than 50% of cardiovascular related deaths each year. In Uganda, more than 25% of adults have high BP with lack of awareness being the main barrier to achieving satisfactory control rates. May measurement month (MMM) is a global initiative aimed at raising awareness of high BP and to act as a temporary solution to the lack of BP screening programmes. A cross-sectional survey of voluntary screenees aged 18 years and above was carried out between May and September 2021. Screening was carried out in two outpatient departments of two referral hospitals within the capital city, Kampala. BP measurements, the definition of hypertension and statistical analysis followed the standard MMM protocol. A total of 1671 people were screened and included in analysis. After multiple imputation, 1018 (60.9%) had hypertension. Of all 1018 participants with hypertension, 765 (75.1%) were aware and 750 (69.3%) were on antihypertensive medicine. Of the participants on antihypertensive medicine, 248 (35.2%) had controlled BP (<140/90 mmHg). Previous history of stroke and taking alcohol 1-6 times per week were significantly associated with higher diastolic BP. The MMM21 Uganda campaign highlights the importance of measuring BP as it generates real-time data on untreated and inadequately treated hypertension. This should motivate government and policy makers to promote routine local screening for BP.
