Background: Little is known about predictors of lifestyle modification in overweight or obese patients with acute myocardial infarctions.
Methods： Between October 2005 and May 2007, 311 overweight or obese patients with an AMI visited Kyungpook National University Hospital. Among them, 216 patients (63±11 years old, 144 males) with ≥1 year of follow - up were included.
Results： Body weight of all patients showed a significant decrease and 20% showed a >3% weight reduction at 1 year of follow-up. Ninety-six (44%) patients were smoking at baseline, and 52% of them had quit by 1 year of follow-up. Only six smokers were successful with both a >3% weight reduction and smoking cessation. In multivariate analysis, age (OR 1.084, 95% CI 1.028-1.144, p=0.003) and smoking cessation (OR 0.167, 95% CI 0.048-0.575, p=0.005) were independent predictors of weight reduction. Abdominal circumference was a negative predictor of smoking cessation (OR 0.903, 95% CI 0.820-0.994, p=0.037).
Conclusions： Mean body weight of all patients showed a significant decrease at follow-up.
Smoking cessation and age were independent predictors of weight reduction, and abdominal
circumference was a negative predictor of smoking cessation.
