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

Abstract

Abstract Hypertension is the biggest contributing risk factor to cerebrovascular disease and is associated with increased risk of coronary artery disease. The May Measurement Month (MMM) campaign is a global initiative aimed at raising awareness of hypertension and acting as a temporary solution to the lack of screening programs worldwide. An opportunistic cross-sectional survey of participants aged ≥18 was carried out during May 2019 in Korea. Over 10 000 participants were recruited in the MMM campaign in Korea, with a slogan of ‘A simple measure to save lives—#checkyourpressure’. A total of 9975 participants with valid clinical and blood pressure (BP) data were used for analysis. All participants were Korean in ethnicity, mean age was 57.2 (SD ± 21.2) years, 57.7% were females, and the mean body mass index was 23.4 kg/m2 (SD ± 3.3). In total, 37.7% of the participants reported a previous diagnosis of hypertension, and 91.3% of those diagnosed were on antihypertensive medications. For other comorbidities, 11.6% reported having diabetes mellitus, 2.0% had previous stroke, and 1.0% had previous myocardial infarction. Mean BP was 130.0/81.0 mmHg in the overall population. After multiple imputation, 47.6% of participants were classified as hypertensive (systolic BP ≥140 mmHg and/or diastolic BP ≥90 mmHg or on treatment for raised BP). Among all hypertensive participants, the awareness rate, the treatment rate, and the control rate (systolic BP <140 mmHg and diastolic BP <90 mmHg) were 76.2%, 74.0%, and 50.5%, respectively. Of those on antihypertensive medication, the control rate was 68.2%. While awareness and treatment rates were relatively high in the MMM19 campaign, the BP control rate of the total hypertensive population was still only ∼50%, which demands more emphasis on strict BP control.
