Objectives： To examine high-risk sexual behaviors among adolescents in China's Mainland and to provide the reference for the future intervention and prevention. Methods： The articles about high - risk sexual behaviors among adolescents were sorted based on our selection and exclusion criteria. We also checked the reference lists of relevant articles. Meta - analysis was conducted to obtain overall effect size of variables on high-risk sexual behaviors among adolescents. Results： In total, 717 articles were sorted and 75 were included. Meta - analysis showed that the average age for sexual behavior debut was 19.38 ± 1.94; the rate of condom use at sexual behavior debut was 37.2% （95% CI：35.5% -38.9% ） ; the occurrence of sexual behav-iors with multiple partners accounted for 33.2% （95% CI：31.0% -35.5% ） and the rate of adolescent pregnancy was 15.1% （ 95% CI ： 13.9% - 16.4% ）. Compared with female adolescents, male adolescents were 2.09 times more easier to have sexual in-tercourse （ OR =2.09, 95% CI： 1.79 -2.39）. Conclusion： The phenomenon of high - risk sexual behaviors among adolescents should attract more concern in China's Mainland. The corresponding intervention and prevention measures should be developed as early as possible.
