  • Results are shown as the differences of percent body fat, the multiplicative factors of HOMA-IR, and the prevalence ratios of IGT and diabetes compared with normal glucose tolerance per 1-SD lower values in anthropometric measurements. The numbers in the parentheses are 95% CI. Model 1 includes only age as a covariate. Model 2 includes age, parental history of diabetes, physical activity, education, income, smoking, and age at menarche. Model 3 includes all variables included in Model 2, plus percent body fat and its interaction with sex.
