Here, we report on the findings of the campaign. Adults aged ≥18 years were recruited opportunistically at hospitals and co-working spaces in all regions of Thailand. Three seated BP readings were taken for each participant, along with the completion of a questionnaire on demographics, lifestyle factors, and comorbidities. Hypertension was defined as a systolic BP ≥ 140 mmHg and/or 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, 10 562 were screened, with a mean age of 50.4 years and 60.8% of whom were female. Of all participants, 4670 (44.2%) had hypertension, of whom 3416 (73.1%) were aware, and 3240 (69.4%) were on antihypertensive medication. Of those on antihypertensive medication, 1957 (60.4%) had controlled BP, and of all participants with hypertension, 41.9% had controlled BP. The MMM campaign in Thailand identified significant numbers of participants with either untreated or inadequately treated hypertension. Appropriate intervention after BP screening together with prescribing suitable BP-lowering regimens should be implemented to enhance BP control.MedicineArticleSCOPUS10.1093/eurheartjsupp/suaf0612-s2.0-10501744413415542815
