Abstract: Objective To systematically review the prevalence of hypertension in Tibetans, China and provide evidence basis for resource allocation in healthcare decision making and health policy. Methods The PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure（CNKI）, WanFang and VIP databases were reviewed to identify potentially eligible articles that provided data on the prevalence of hypertension in Tibetans, China before February 28, 2019. Two investigators independently assessed articles according to eligibility criteria, extracted data and assessed the risk of bias. Statistical analysis was completed using Stata software version 12.0. Results A total of 17 articles with 64 481 subjects were eligible, and thereof 12 articles included 55 718 subjects aged ≥18 years. Overall prevalence of hypertension in Tibetans aged ≥18 years was 36%（95% confidence interval: 26% to 46%, similarly hereinafter）. Upon stratification by age, the prevalence of hypertension was 14%（6% to 22%）, 40%（32% to 47%） and 58%（46% to 71%） in Tibetans aged 18-＜36, 36-＜60 and ≥60 years, respectively. By gender, hypertension was found in 39%（31% to 47%） males and 34%（26% to 43%） females. By region, the prevalence of hypertension was 36%（28% to 44%） in urban areas, 33%（20% to 46%） in rural areas and 36%（32% to 40%） in pastoral areas. By survey year, the prevalence of hypertension was 38%（32% to 43%）, 32%（22% to 41%） and 34%（29% to 39%） in 2002-2012, 2013-2015 and after 2016, respectively. By the geographic altitude, the prevalence of hypertension was 16%（12% to 21%） between 1.5-3.0 km, 33%（25% to 42%） between ＞3.0-4.0 km and 47%（37% to 57%） above 4.0 km, respectively. The rates of awareness, treatment and control of hypertension were 45%（32% to 58%）, 30%（22% to 38%） and 7%（4% to 10%）, respectively. Conclusion The prevalence of hypertension in Tibetans, China is high, while the awareness, treatment and control rates are relatively low.
