摘要Objective:To explore the effect of peer education on improving the knowledge,attitude,practice level(KAP)to prevent human papilloma virus(HPV)infection among college students.Methods:The knowledge,attitude/belief,and practice level of 536 grade I college students from a university in Shanghai were surveyed and analyzed using a self-designed questionnaire—the HPV Infection and Prevention KAP Questionnaire.Results:Many college students heard about HPV vaccine(49.70％before peer education and 100％after peer education);however,few of them were vaccinated(2.82％before peer education and 5.23％after peer education).Knowledge,attitude/belied,and practice of HPV infection prevention were positively related(P＜0.05).Peer education was effective in improving college students'KAP level of HPV infection prevention(P＜0.05).Conclusions:Peer education could be used as a strategy in colleges to improve student's KAP level of HPV infection prevention.College students may also be encouraged to spread their influence to society.
