Abstract: Objective　To evaluate the effect of information⁃knowledge⁃attitude⁃practice (IKAP) theory⁃based health education interventions on clonorchiasis control among community residents and primary school students in Torch High⁃tech Development Zone of Zhongshan City, so as to provide insights into formulation of clonorchiasis control strategies among different types of populations. Methods　Residents were randomly sampled from two communities and students from two primary schools using a random cluster sampling method in Torch High⁃tech Development Zone, Zhongshan City from 2019 to 2021, and health education pertaining to clonorchiasis control was performed based on the IKAP theory. The changes in the awareness of basic clonorchiasis control knowledge and belief, self⁃reported risk of Clonorchis sinensis infections and dietary behaviors were compared among community residents and primary school students before and after health education interventions. Results　The participants included 146 male and 151 female community residents and 158 male and 153 female primary school students, with no significant difference detected in gender distribution ([χ2] = 0.16, P > 0.05). The mean awareness of basic clonorchiasis control knowledge increased by 44.71% and 43.28% among primary school students and community residents 6 months following health education, and there were significant differences in the awareness of each item of basic clonorchiasis control knowledge before and after health education ([χ2] = 41.53 to 284.44, all P values < 0.05). The proportions of primary school students and community residents thinking very high and high risks of C. sinensis infections increased from 9.35% and 6.71% before health education to 22.15% and 37.75% after health education, but only the difference of the attitudes in community residents achieve statistical significance ([χ2] = 92.18, P < 0.05). The frequency of separation of raw and cooked foods with chopping board and knife significantly increased among community residents and primary school students following health education ([χ2] = 16.04 to 62.65, all P values < 0.05). The frequency of eating raw freshwater fish ([χ2] = 32.85，P < 0.05), fish congee ([χ2] = 7.02，P < 0.05) and fish fillet hot pot ([χ2] = 4.88，P < 0.05) significantly reduced among primary school students following health education, while only the frequency and proportions of eating raw freshwater fish have significantly reduced in community residents ([χ2] = 11.77, P < 0.05). Conclusions　Health education interventions based on the IKAP theory are effective to increase the awareness of clonorchiasis control knowledge and improve dietary behaviors associated with C. sinensis infections among community residents and primary school students in Zhongshan City.
