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.Keywords: hypertension, prevalence, awareness, treatment, control rate
