  1. Odds ratios were calculated using multivariate logistic regression models. All covariates listed were simultaneously included in the model. Cigarette smoking, alcohol consumption, level of leisure-time physical activity, serum cholesterol levels, educational level, and level of economic development were not significantly associated with the risk of diabetes and were not included in the final model. In this study, the data of BMI and WR have significant correlation, so we selected central obesity in the final model. Central obesity was defined as a waist circumference of 90 cm or more in men and 80 cm or more in women
