Abstract: Objective：To provide suggestions for future decision鄄making and studies of adolescent sex
and reproductive health interventions. Methods：World Health Organization （宰匀韵） provides Cochrane
systematic reviews for the world by Reproductive Health Library （砸匀蕴）. An extensive search of systematic
reviews about adolescent sex and reproductive health interventions of RHL（2009，12th version）was undertaken.
A pooled analysis and summary was taken about these systematic reviews. Results：Total 7 systematic reviews
were selected and 168 studies that recruited at least 147 265 adolescents were included. The outcome indicators
of these reviews included knowledge，attitude，willingness of condom use，abstinence increase，the age of first
coitus，number of sexual partners，sexual frequency，unprotected sex，contraception use，condom use，STD
diagnosis and service utilization. The results of these systematic reviews were displayed as follows: 淤The
knowledge of sex and reproductive health significantly increased among intervened adolescents. 于The attitude
and willingness of contraception use were improved. 盂The age of adolescent first coitus was postponed，and their
sexual frequencies decreased. 榆After adolescents received education and training，the number of their sexual
partners decreased. 虞Contraception use，especially condom use obviously increased. Conclusions：Based on
results of these 7 systematic reviews，current intervention programs of sex and reproductive health for youth are
mildly or moderately effective. But there are significant flaws in the designs of some intervention studies and the
effectiveness evaluation of these included studies need to be strengthened and improved.
