Introduction. Young people are at the centre of the global HIV/AIDS epidemic. This study therefore aimed to evaluate the effectiveness of peer education in improving HIV knowledge, attitude, and preventive practices among in-school adolescents in Osun State, Nigeria. Methods. This was an intervention study that was carried out among in-school adolescents attending mixed secondary schools in Osun State, Nigeria. The study was in three stages: before intervention, intervention, and after intervention. The impact of peer education was evaluated twelve weeks after intervention. Data were collected using pretested semistructured questionnaires and data analysis was done with SPSS version 16. Results. At the preintervention stage, the study and control groups were similar in their sociodemographic characteristics, HIV knowledge, attitude, and preventive practices, including high risk behaviours for HIV/AIDS transmission. After the peer education intervention, those with good knowledge and positive attitudes towards HIV/AIDS increased significantly from 50.0% to 86.7% and from 49.0% to 85.6%, respectively (P < 0.05). Conclusion. The study showed that peer education is effective in improving knowledge, attitude, and some preventive practices towards HIV/AIDS among in-school adolescents. Educational programmes about HIV/AIDS should therefore be designed to target this age group putting into consideration their unique characteristics.
