Effects of Peer-Based Intervention on Prevention Behavior of Sexually Transmitted Infections and Unwanted Pregnancy in Adolescents: A Meta Analysis

[摘要] Background: In facing the transition peri­od, many adolescents tend to explore their sexu­ality and engage in risky sexual beha­vior. This risky behavior is a main contri­bu­tor to sexually transmitted infections (STIs) and unintended pregnancy. Peer-based in­ter­vention is often used in programs that promote sexual and reproductive health in ado­lescents, including prevention of STIs and unintended pregnancy. This study ai­med to examine the effect of peer-based interventin on STI and unintended preg­nancy preventive behavior among adoles­cents. Subjects and Method: This was a meta-ana­­lysis study that was carried out accor­ding to the PRISMA guidelines. The articles with rando­mized controlled trial study de­signs published in 2000-2020 were in­clu­ded for the meta-analysis. Several data­bases were used in search­ing for the arti­cles. The articles obtained were screened to obtain the articles that met the eligibility criteria. The articles were analyzed using Rev­Man 5.4. Results: There were 14 articles that met the criteria for a meta-analysis with a sample size of 18,325. The study showed that peer-based intervention was statistically signifi­cant in improving sexually trans­mitted in­fec­tion pre­ventive behavior (RR= 1.15; 95%CI= 1.02 to 1.30; p= 0.020) and unintended pregnancy pre­ven­tive behavior among ado­les­cents (RR= 1.14; 95% CI= 1.00 to 1.30; p=0.040). Conclusion: Peer-based intervention sho­uld be considered as an effort to promote STIs and unintended pregnancy preventive behavior among adolescents.
