RESUMEN
OBJECTIVE: To explore the impact of self-efficacy on the behavior of contacting schistosome cercarial infested water among middle school students. METHODS: In the transmission control area and endemic control area of the schistosomiasis endemic regions in Hubei Province, a total of 3 204 middle school students were selected through the stratified cluster random sampling method and investigated by questionnaires. RESULTS: The incidence rates of contacting infested water with Oncomelania hupensis snails during the past 3 and 12 months among the middle school students were 11.4% (364/3 204) and 14.8% (474/3 204) respectively, while those of contacting indefinite infested water during the past 3 and 12 months were 23.8% (762/3 204) and 28.0% (898/3 204) respectively. The awareness rate of schistosomiasis prevention and control knowledge was 82.1% (2 631/3 204). There were "knowledge-practice separation"in the prevention and control of schistosomiasis among the middle school students. The correlation analysis and Logistic regression analysis showed that the self-efficacy of schistosomiasis protective behavior of middle school students was a protective factor for contacting with infested water, with the adjusted odds ratio values of 0.882, 0.886, 0.914 and 0.927. CONCLUSIONS: Self-efficacy of schistosomiasis protective behavior is a protective factor for contacting with infested water among middle school students, and improving their self-efficacy may be an effective strategy to settle the problem of"knowledge-practice separation".
