The aim of this study was to determine the effect of educational intervention (EI) based on health belief model (HBM) on preventive behaviors of type 2 diabetes.Methods: The educational trial study was conducted in 2019-2020 among 143 high school male students at risk in Khash city (in southwestern Iran), using a random cluster method in two intervention and control groups. Data collection tools were demographic characteristics, knowledge, model constructs and disease prevention behaviors questionnaires. The training program was held in 7 one-hour sessions. Data were collected before, immediately and three months after the intervention and analyzed by SPSS 20 software using Chi-square, Independent t-test and Repeated Measures ANOVA at significant level of 0.05. Results: Immediately after the implementation of the training program in the intervention group, a significant increase was observed in the mean scores of knowledge, model constructs and behavior (P =0.0001). Three months after the EI, there was a significant difference between the mean scores of knowledge, perceived barriers, Cues to action and behavior between the two groups (p <0.05).Conclusion: Considering the effect of EI based on HBM on the promotion of diabetes prevention behaviors in students, the design, implementation and evaluation of theory-based EIs in the control and prevention of diabetes in adolescents is recommended.
