BACKGROUND AND OBJECTIVES Hypertension (HTN) is the most contributable risk factor for cardiovascular disease. May Measurement Month (MMM) is a global initiative to raise awareness of HTN and act as a temporary solution to the lack of screening programs worldwide.

METHODS An opportunistic cross-sectional survey of participants aged ≥18 was carried out in May 2019. Over 10,000 participants were recruited in the MMM 2019 Korea, with a slogan of "A simple measure to save lives - #checkyourpressure."

RESULTS A total of 9,950 participants with valid clinical blood pressure (BP) data were used for analysis. All participants were Korean in ethnicity. The mean age was 57.2±21.2 years, 57.8% were females, and the mean body mass index was 23.4±3.3 kg/m². Among the enrolled population, 20.1% were less than 30 years old, and 5.0% were 30-39 years old. 37.0% of the participants reported a previous diagnosis of HTN, and 91.3% of those diagnosed were on antihypertensive medications. Notably, more than 20% of the participants had not measured their BP during the last 12 months, and the awareness rate in the young hypertensive participants (aged <40) was less than 10%. Among hypertensive participants, the treatment rate was 69.3%, and the control rate among those taking medications was 61.2%.

CONCLUSION MMM 2019 Korea campaign reported high BP control rates in individuals with HTN, reaching 60%. However, the awareness rate in young hypertensive participants was less than 10% along with suboptimal management status. The MMM 2019 Korea again raised the importance of regular BP measurement in the younger population.
