Abstract
Background: Dietary modification has a significant effect on reducing the myocardial infarction (MI) mortality and its recurrence. This study aimed to investigate the effect of education on the dietary intake of patients with a MI based on the health belief model.
Materials and Methods: This is a quasi-experimental study conducted on patients with a MI from October 2021 to January 2022. A total of 72 cases with MI were randomly divided into the intervention and control groups. The intervention group received educational intervention based on the health belief model for 3 months in four sessions. The structures of the health belief model were measured using a questionnaire, before the intervention and 1 and 3 months following it. dietary intake was measured with a 3-day dietary record before and after 3 months of the intervention.
Findings: After the educational intervention, a significant difference was observed between the two groups in terms of the average scores of awareness, perceived susceptibility, perceived severity, perceived benefits, and self-efficacy (P<0.01). However, no significant difference was observed concerning the perceived obstacles. Although there was no significant differences between dietary intake at the baseline, the intake of energy, cholesterol and energy percent from carbohydrate, total fat and saturated fatty acids were lower and fiber intake was higher in intervention vs. control group after intervention (all P<0.05).
Conclusion: Given the positive effect of the health belief model in this study, it is suggested to use this model for designing education for MI patients focusing on nutrition.
