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

ABSTRACT

Blood pressure (BP) measurement is the mainstay for diagnosing and treating hypertension. Blood pressure screening in the May Measurement Month (MMM) project is helpful for the early detection of hypertension, which is usually asymptomatic. This study aimed to investigate the epidemiology of hypertension from data in the MMM21 project in Thailand. A cross-sectional study was conducted according to the MMM clinical study protocol for MMM21 in all regions of Thailand from August to November 2021. We included adults aged ≥18 years. Baseline characteristics, history of hypertension diagnosis, and treatment were collected through the questionnaires followed by three standardized BP measurements, 1 min apart. We included 10 940 participants with a mean age of 41.3 (SD ± 13.5) years. Only 6% never had their BP measured before. Of all participants, 30.2% had hypertension, and among this hypertensive population, 50.3% were aware, and 46.2% were taking antihypertensive medications. Of participants with hypertension, 31.6% had controlled BP (<140/90 mmHg), and BP control was 68.5% among those taking antihypertensive medication. The proportion of participants who had diabetes, were on aspirin, and were on statin were 6, 7.2, and 11.4%, respectively. Almost all participants (93.7%) had received at least one COVID-19 vaccination, and 8.0% reported a previous COVID-19 positive test. Most of the participants (97.4%) received hypertension care at no cost. Hypertension awareness and overall BP control rate were relatively low, while most subjects had previously had their BP checked. The widespread use of BP measurement may improve the diagnosis and treatment of hypertension to improve the care of those with hypertension in Thailand.
