The Association between Lifestyle-related Risk Factors and Coronary Artery Disease in Residents of Yazd Province: A Case-control Study

Background: This study was conducted to investigate the relation between risk factors related to lifestyle and coronary artery disease (CAD) in residents of Yazd province. Methods: In this hospital-based case-control study performed in Yazd province, ۲۵۰ patients with CAD were compared with ۲۵۰ controls matched for age and sex. Data were collected by using a researcher- made questionnaire. Data analysis was performed using Chi-square and Conditional Multiple Logistic Regression and through SPSS۱۶. Results: History of Consumption of less than three servings of fruit in week, with an odds ratio of ۸.۴ (۹۵%CI: ۱.۵۶-۴۵.۱۸) and more than three times egg in week with an odds ratio of ۴.۰۵ (۹۵%CI: ۱.۱۳-۱۴.۵, P=۰.۰۳) increased the chance of getting CAD. However, no significant relationship was found for history of consumption of oil, dairy, red meat, fried foods and fast foods. The number of daily smoked cigarettes was the only non-nutritional factor that showed significant relationship with CAD (P=۰.۰۱). Conclusion: Overall, insufficient intake of fruits, high consumption of egg and the number of cigarettes smoked daily were identified as the most important life style-related risk factors for getting CAD. Therefore, measures for decreasing these risk factors in Yazd Province are necessary.
