May Measurement Month 2020: An Analysis of Blood Pressure Screening Results From China

We reported the blood pressure data obtained in the May Measurement Month (MMM) China project in 2020 during the COVID-19 control period. The study participants were adults (≥ 18 years), ideally in whom blood pressure had not been measured in the previous year. Blood pressure was measured three times consecutively with a 1-min interval in the sitting position, using a validated automated BP monitor (Omron HEM-7081IT), and transmitted to a central database via a smartphone app. The measurement was performed at 136 sites across 29 China provinces. The 100 728 participants had a mean (±SD) age of 45.6 (±18.3) years and included 56 097 (55.7%) women. The mean systolic/diastolic blood pressure was 120.0/76.9 mm Hg. The proportion of hypertension was 28.9% (n = 29 135), and the awareness, treatment, and control rates of hypertension were 45.3% (n = 13 212), 39.7% (n = 1573), and 24.4% (n = 7101), respectively. After adjustment for age, gender, and use of antihypertensive medication, systolic/diastolic BP were significantly higher with cigarette smoking (n = 8070, +0.5/+1.0 mm Hg, p < 0.05), mild (n = 4369, +1.2/+1.3 mm Hg, p < 0.001) and moderate or heavy alcohol drinking (n = 3871, +0.4/+0.7 mm Hg, p < 0.05), and overweight (+1.8/+1.4 mm Hg, p < 0.001) and obesity (+2.3/+1.5 mm Hg, p < 0.001). In conclusion, our study provided unique blood pressure data during the COVID-19 period, and suggested that hypertension management might have been even more challenging when the medical professionals had to shift their focus on other urgencies.
