Name of journal: CirculationAbstract: <b>Background</b> -Although the prevalence of hypertension (HTN) continues to increase in developing countries including China, recent data are lacking. A national wide survey was conducted from October 2012 to December 2015 to assess the prevalence of HTN in China. <b>Methods</b> -A stratified multistage random sampling method was used to obtain a nationally representative sample of 451,755 residents aged >=18 years from 31 provinces in mainland China from October 2012 to December 2015. Blood pressure (BP) was measured after resting for 5 minutes by trained staff, using a validated oscillometric BP monitor. HTN was defined as systolic BP (SBP) >=140 mmHg and/or /diastolic BP (DBP) >=90 mmHg and/or use of antihypertensive medication within two weeks. Pre-HTN was defined as SBP 120-139 mmHg and DBP 80-89 mmHg without antihypertensive medication. HTN control was defined as SBP <140 mmHg and DBP<90 mm Hg. In addition, the prevalence of HTN (SBP>=130 or DBP>=80 mmHg) and control rate (SBP<130 and DBP<80 mmHg) of HTN were also estimated according to the 2017 American College of Cardiology (ACC) /American Heart Association (AHA) High Blood Pressure Guideline. <b>Results</b> -Overall, 23.2% (estimated 244.5 million) of the Chinese adult population aged >=18 years had HTN, and another 41.3% (estimated 435.3 million) had pre-HTN according to the Chinese guideline. There were no significant differences of HTN prevalence between urban and rural residents (23.4% vs. 23.1%, P=0.819). Among individuals with HTN, 46.9% were aware of their condition, 40.7% were taking prescribed antihypertensive medications, and 15.3% had controlled HTN. Calcium channel blockers were the most commonly used antihypertensive medication (46.5%) as monotherapy; and 31.7% of treated hypertensive patients used two or more medications. The prevalence of HTN based on the 2017 ACC/AHA guideline was twice as high as that based on 2010 Chinese guideline (46.4%), while the control rate fell to 3.0%. <b>Conclusions</b> -In China, there is a high prevalence of HTN and pre-HTN; awareness, treatment and control of HTN were low. Management of medical therapy for HTN needs to improve.All authors: Chen Z, China Hypertension Survey Investigators, Dong Y, Gao R, Hao G, Shao L, Tian Y, Wang J, Wang X, Wang Z, Weintraub WS, Zhang L, Zhang Z, Zheng C, Zhu MFiscal year: FY2018Digital Object Identifier: Date added to catalog: 2018-02-28
