Purpose: Little is known about the recent trends of hypertension in southern China. The aim of the study was to investigate the trends of hypertension in Guangdong Province between 2012 and 2019.
Methods: We conducted two cross-sectional surveys in 2012 and 2019 in southern China, which included 10,970 and 27,483 participants, respectively, aged 35 to 75 years old using a method of stratified, multistage, and cluster sampling. Hypertension was defined as a mean systolic/diastolic blood pressure (SBP/DBP) ≥ 140/90mmHg, or a self-reported condition, or any pharmacological treatment in the last 2 weeks. In addition, according to the 2017 ACC/AHA guideline for high blood pressure, we estimated the prevalence and control rate of hypertension.
Results: According to the 2010 Chinese guideline, the age-standardized rate of hypertension prevalence was 34.7% in 2012 and 36.9% in 2019 with a slight increase, while the prevalence of prehypertension was stable (14.5% vs 14.3%). Over the period of our study, 45.6% and 60.7% of hypertensive patients knew their diagnosis in 2012 and 2019, and 40.8% and 51.5% were using antihypertensive medications, respectively. The control rates increased from 15.1% to 23.6%. Hypertension prevalence was 64.5% in 2012 and 63.2% in 2019, and the control rate increased from 3.0% to 4.8% during the study period under the 2017 ACC/AHA guideline.
Conclusion: Although the past 7 years have seen some progress in hypertension management, the rates of hypertension awareness, treatment, and control in southern Chinese remained regrettably low, and the prevalence rate was still high.
