Odds ratios (95% confidence intervals) for diabetes corresponding to measured variables.

Logistic regression model adjusted for cigarette smoking and alcohol consumption, level of leisure-time physical activity, serum cholesterol, resident area, and personal income in step 1. Because the aforementioned variables were not significantly associated with diabetes, we excluded them in the final model. In step 2, all variables fitted into the final model are presented in Table 3. Odds ratios (95% confidence intervals) for diabetes corresponding to measured variables.
