The aim of the present study was to examine the effects of education based on the Health Belief Model on the dietary Behavior of patients following Coronary artery bypass graft surgery (CABG) at the Heart Surgery Department of Shahid Beheshti Hospital of Qom. Methods: In this semi-experimental clinical trial, data were collected on 64 patients, at an average age of 59. 9 ± 7. 26 years in the intervention group and 58. 5 ± 7. 6 years in the control group. Seventy percent of the study subjects were male and 30% were female. Intervention and control groups were given a questionnaire, comprising 56 questions in 5 parts. The educational intervention was aimed at creating perceived susceptibility and perceived severity in the intervention group. After 1 month. Both groups were tested, and the resulting data were analyzed to investigate the effects of the educational intervention on the nutritional Knowledge and Behavior of the patients. Results: According to the results, educational intervention caused a significant increase in the mean scores of Knowledge (p value = 0. 001), perceived severity (p value = 0. 007), and perceived benefits and barriers (p value = 0. 003) in the intervention group but did not cause a significant increase in the mean score of nutritional Behavior (p value = 0. 390). Conclusion: Education based on the Health Belief Model seems to be effective in improving nutritional Knowledge, but more consistent and comprehensive educational programs are necessary in order to change Behavior and improve nutritional Behavior.
