Effectiveness of peer-led education on knowledge, attitude and risk behavior practices related to HIV among students at a Malaysian public university - A randomized controlled trial

摘要

Objective: Develop, implement and evaluate the effectiveness of a peer-led education program related to HIV/AIDS among university students. Method: Design: randomized controlled trial with 276 university students at Faculty of Medicine and Health Sciences University Putra Malaysia (UPM), Serdang in 2011.Intervention: A peer-led education program on HIV prevention by university students.Outcome: differences in knowledge, attitude and risk behavior practices related to HIV between baselines, immediate follow-up after intervention and after three months. Results: Significant improvement in sound knowledge in the intervention group as compared to the control group (Odds ratio, 1.75; 95% CI 1.01, 3.00; p=0.04) and improvement in good attitude related to HIV (Odds ratio 2.22; 95% CI 1.37, 3.61; p=0.01). The odds of high substance risk behavior was significantly reduced in the intervention group as compared to the control group (Odds ratio 0.07; 95% CI 0.02, 0.34; p=0.01). The association between good knowledge and intervention was modified by the different time points (baseline, immediately after intervention and 3. months after intervention), ethnicity and gender. Conclusion: Peer-led education program in HIV prevention improves knowledge, attitude and substance risk behavior. Changes in sexual risk behavior may require a longer follow-up.
