*Covariates in Model I: age, ethnicity, family history of diabetes, breastfeeding status, β-cell function at 3 months' postpartum, and gestational glucose tolerance group.
**Covariates in Model II: covariates in Model I + waist circumference at 3 months' postpartum.
***Covariates in Model III: covariates in Model II + change in weight between 3 months' and 12 months' postpartum.
