Objective A Meta-analysis is conducted to systematically review the findings of all the past 15 years' studies and estimate the overall prevalence of hypertension of Chinese children and adolescents,and to grasp the epidemiological characteristics and provide evidence for targeted prevention measures. Methods Comprehensive electronic searches of Chinese Web of Knowledge (CNKI),Wei Pu (VIP),Wan Fang,PubMed and Web of Science were conducted to identify any study in each database published from January 1,2000 to December 31,2015,reporting the prevalence of hypertension of Chinese children and adolescents.Then,combining prevalence rate in R software. Results Totally 48 studies were included in this study.The hypertension prevalence of Chinese children and adolescents was 6.47%(95%CI=5.41%～7.73%).Males were higher than females regardless of age (puberty 6.75% vs 5.87%,before puberty 9.25% vs 7.61%).The female growth of prevalence rate was slower than men.The north(7.91%)was more serious than the south(5.31%)and the prevalence of the east was the highest.Meanwhile,the urban(8.70%)was more serious than the rural(7.60%);In general,the rate decreased (8.06% vs 5.10%),but rebounded in the past five years (6.89%). Conclusions The prevalence of hypertension in Chinese children and adolescents can not be ignored.Health education,reasonable diet and exercise are all the necessary measure.
