Summary of Training Content for Peer Educators.

BackgroundSchistosomiasis, a neglected tropical disease (NTD), remains a public health concern in China. Health education is a fundamental intervention for its control. Even in transmission-interrupted areas like Wuhan, sustained awareness is crucial. However, recent literature on school-based interventions evaluating knowledge, attitudes and practices (KAP) among children in such areas is limited.ObjectiveThis study aimed to evaluate and compare the effectiveness of peer-led education versus routine health education in improving schistosomiasis-related KAP among elementary students in an urban area where schistosomiasis transmission has been interrupted.MethodsA quasi-experimental school-level trial was conducted from October 2021 to January 2022 among 1013 fourth- and fifth-grade students of Yucai Hankou and Dijiao primary schools in Jiang’an district, Wuhan, China. Students were randomly assigned to two groups. Group I (n = 524) received peer-led education, while Group II (n = 489) received routine health education. Schistosomiasis-related KAP were assessed via standardized questionnaires at baseline and one month post-intervention. Statistical analyses followed the intention-to-treat principle, using multiple imputation for missing baseline data. Intervention effects were evaluated via analysis of covariance (ANCOVA) and multivariable logistic regression, adjusting for baseline scores and demographic covariates.ResultsFollowing the intervention, both peer-led and routine health education interventions significantly improved schistosomiasis-related KAP scores among schoolchildren. For knowledge scores, both groups showed significant improvement from baseline to follow-up (within-group change: 2.93 for Group I vs. 0.98 for Group II, both P P P P P = 0.237). In terms of binary outcomes, the odds of achieving good knowledge were 6.04 times higher in Group I compared to Group II (aOR = 6.04, 95% CI: 4.43 to 8.24, P ConclusionPeer-led education is more effective than routine health education in improving schistosomiasis-related knowledge among primary school students in a transmission-interrupted area. Although both approaches enhanced KAP, the peer-led model demonstrated superior knowledge gains. These findings support the integration of peer-led strategies into sustainable school-based health education programmes to maintain schistosomiasis awareness and support ongoing control efforts in post-transmission settings.
