May Measurement Month 2022: an analysis of blood pressure screening results from Mauritius

May Measurement Month (MMM) is a global campaign initiated by the International Society of Hypertension aimed at raising awareness of high blood pressure (BP) and to act as a temporary solution to the lack of screening programmes worldwide. We provide the results of the MMM 2022 (MMM22) campaign in Mauritius. Adults aged ≥18 years were recruited opportunistically at workplaces and community centres, in both rural and urban areas across Mauritius. Three seated BP readings were taken for each participant, along with completion of a questionnaire on demographics, lifestyle factors, and comorbidities. Hypertension was defined as a systolic BP ≥140 mmHg and/or a diastolic BP ≥90 mmHg or being on antihypertensive medication. Controlled BP was defined as being on antihypertensive medication with a BP <140/90 mmHg. Multiple imputation was used to estimate any missing BP readings. In total, 8953 were screened, with a mean age of 43.6 years and 62.2% of whom were female. Out of 8953 participants, 2024 participants (22.6%) had hypertension, of whom 1066 (52.7%) were aware, and 884 (43.7%) were on antihypertensive medication. Of those on antihypertensive medication, 550 (62.2%) had controlled BP, and of all participants with hypertension, 550 (27.2%) had controlled BP. The MMM campaign in Mauritius identified significant numbers of participants with either untreated or inadequately treated hypertension. May Measurement Month 2022 was the largest BP screening campaign undertaken in Mauritius. These results suggest that MMM22 was useful in the identification of patients with raised BP for further investigation and follow-up.
