Using various models of behavior change, a number of studies in the area of nutrition education have confirmed thatnutrition habits and behaviors can be improved.Objectives: This study sought to determine the effects of education on patterns of dietary consumption among medical studentsat the military university of Tehran, with a view to correcting those patterns.Methods: In this quasi-experimental study, 242 medical students from the Military University of Tehran were chosen by conveniencesampling and then divided into control (n = 107) and intervention groups (n = 135) by block randomization. The self-administeredquestionnaire involving six categories of item (knowledge, perceived benefits, perceived barriers, perceived threats, self-efficacyand behavior) has been validated (Cronbach alpha > 0.7 for each).Results: Following the educational intervention, the mean score of knowledge, health belief model (HBM) structure, and behaviorof students in relation to healthy patterns of food intake increased significantly (P < 0.05). The mean pre-intervention knowledgescore was 6.76 (1.452), referring to threats to HBM constructs including perceived threat 2.93 (1.147), perceived benefits 7.28 (1.07),perceived barriers 5.44 (1.831), self- efficacy 4.28 (1.479), and behavior 8.84 (2.527). The post-intervention scores all improved as follows:knowledge 8.3 (1.503), perceived threats 3.29 (1.196), perceived benefits 7.71 (0.762), perceived barriers 5.9 (1.719), self- efficacy4.6 (1.472), and behavior 9.45 (2.324). This difference in mean scores for knowledge, health belief structures and employee behaviorbefore and after educational intervention was significant (P0.05).Conclusions: The significant improvement in the experimental group’s mean knowledge, HBM structures , and behavior scoresindicates the positive effect of the intervention.
