To investigate the long-term natural trends in the status of hypertension in rural northeast China from 2013 to 2018.
Two successive cross-sectional surveys were conducted in Liaoning rural areas in 2013 and 2018, which included 10 753 and 10 926 participants aged at least 40 years from different villages, respectively. A multistage, stratified, and cluster random sampling method was used to ensure that the samples of the two studies were representative. Hypertension was defined as a mean SBP at least 140 mmHg or a mean DBP at least 90 mmHg, and/or self-reported use of antihypertensive medication within the past 2 weeks. The prevalence and control rate of hypertension were also estimated according to the 2017 American College of Cardiology/American Heart Association high blood pressure guideline.
Overall, the age-standardized prevalence of hypertension increased from 52.3 to 53.6%, while the age-specified DBP level increased by 5.2% (82.4 vs. 86.7 mmHg) during the study period. However, the control rate unfortunately remained low (4.1 vs. 3.6%), despite unsatisfied awareness and treatment rates of hypertension in rural northeast China. Under the 2017 American College of Cardiology/American Heart Association guideline, the prevalence of hypertension increased from 73.9 to 79.1%; however, the control rate decreased sharply from 1.8 to 0.5% between 2013 and 2018.
Despite the high prevalence of hypertension during the past 5 years, blood pressure levels increased significantly, especially the DBP level. Awareness, treatment, and control of hypertension remained unacceptably low. Therefore, strategies targeting the management of hypertension should be emphasized in rural northeast China.
