BACKGROUND: Nutrition intervention is an integral part of type 2 diabetes care. Dietary management entails a series of eating behavior changes regarding meal planning, food selection, food preparation, dinning out, portion control, as well as appropriate responses to eating challenges. MATERIALS AND METHODS: This quasi-experimental study was conducted on 140 type 2 diabetes patients referring to Torbat Heydariyeh comprehensive health service centers in Iran. The sampling method was as follows: First, Torbat Heydariyeh city was divided into two regions; then, from any area two comprehensive health service centers were randomly selected as the case group, and similarly, two other comprehensive health service centers were selected as the control group. The participants were randomized into experimental and control groups. RESULTS: The results of the present study indicated the effectiveness of training sessions based on the theory of planned behavior on the intervention group in increasing awareness, correct attitude toward behavior, behavioral intention, mental norms, and behavioral control of these individuals. The intervention group also showed a significant increase in the mean scores of the theory components after the training program. CONCLUSION: Given that the importance of nutrition in diabetic patients is an inevitable part of this disease, by providing educational solutions and increasing the health literacy of these people, a big step can be taken toward improving the nutritional behaviors of diabetic patients.
