Peer Education Interventions for Adolescent Sexual Health

Peer education interventions engage adolescents as both learners and educators to promote accurate information, foster supportive norms and encourage positive decision-making around sexual health. Rooted in theories of social learning and empowerment, these interventions capitalise on shared experiences and conversational styles within youth networks. Models range from school-based curricula, where trained students deliver structured sessions on contraception, sexually transmitted infection prevention and communication skills, to community-led initiatives in which local youths facilitate workshops for out-of-school peers. Digital adaptations have also emerged, incorporating moderated online platforms to extend reach and tailor content to diverse contexts. Studies show that peer engagement commonly yields significant gains in knowledge and self-efficacy, and in some settings contributes to delayed sexual debut or reduced unprotected intercourse. However, evidence for sustained behavioural change remains mixed, often reflecting variations in training intensity, cultural adaptation, evaluation quality and ongoing support. Critical success factors include comprehensive preparatory training, ongoing mentorship, interactive participatory methods and alignment with broader health services. When well implemented, peer education can strengthen adolescents’ sense of agency, normalise help-seeking and bridge gaps between formal health systems and young people’s real-life concerns.
