Each model was adjusted for age, ethnicity, family history of diabetes, duration of breastfeeding, BMI at 1 year, change in BMI from 1 to 3 years, and the baseline measure of the respective outcome variable at 1 year postpartum.

Abbreviations: BMI, body mass index; HOMA-IR, homeostasis model assessment-insulin sensitivity/resistance; ISSI, insulin secretion-sensitivity index-2.
