BACKGROUND: Making insecticide-treated nets (ITNs) utilization a social norm would support the global goal of malaria eradication and Ethiopian national aim of its elimination by 2030. Jimma zone is one of the endemic settings in Ethiopia. This study aimed to report effects of malaria education, delivered by students, on community behaviours; particularly ITNs. METHODS: In pre-posttest, cross-sectional household surveys conducted in rural villages of 5 districts in Jimma Zone, Ethiopia, 762 households were sampled. The intervention engaged students from primary schools in participatory peer education within small groups, followed by exposing parents with malaria messages aimed at influencing perceptions and practices. The data were analysed using SPSS version 20.0. Proportions/means differences were computed to compare changes in exposure, knowledge, perceptions, and practices using 95% CI at p < 0.05. Regression analyses were conducted to assess exposures to school-based education, content intensity, perception, and access related predictors of ITN utilization over the intervention periods. RESULTS: Over the intervention periods, the findings showed significant improvement in exposure to and content intensity of malaria messages delivered by students, effect size (ES) = 44.5% and 19.3%, p < 0.001, respectively. ITN utilization (ES = 25.8%), and the reported behaviour of giving ITN priority to children under 5 years old and pregnant women increased by ES = 16.3% and 24.8%, respectively. The exposure status or content intensity of malaria education, in turn, significantly improved comprehensive knowledge about malaria (β = +1.82), misconceptions about causes (β = - 11.46), awareness of caring for ITN (β = +24.79), identifying ITN as effective preventive methods (OR = 1.93), attitude towards ITN (β = +0.20), perceived efficacy of ITN (OR = 1.04), acceptance of ITN as a means to control the danger of malaria (β = +8.08%), and ITN utilization (OR = 1.85). Nonetheless, perceived threat (β = - 0.19) significantly negatively correlated with exposure to students' messages. Socio-demography, access, exposures to messages, and parental perception that students were good reminders predicted ITN utilization over the intervention periods with some changing patterns. CONCLUSIONS: Exposing the community to malaria education through students effectively supports behaviour change, particularly ITN usage, to be more positive towards desired malaria control practices. A school-based strategy is recommended to the national effort to combat malaria.
