Abbreviations: >90th percentile, number of participants with outcome in each GWG category; %, percent of participants with outcome in each GWG category; 95% CI, 95% Confidence Interval; GWG, gestational weight gain; N, number of participants in each GWG category; OR, odds ratio.
Model I for sum of skin folds >90th percentile, birth weight >90th percentile, and percent body fat >90th percentile is considered adjusted for gender of infant, race, parity, and study center.
Model I for cord serum C-peptide >90th percentile is adjusted for study center.
Model II is adjusted for gender of infant, race, parity, study center, pre-pregnancy BMI, maternal age, OGTT z-score sum, alcohol use during pregnancy, smoking during pregnancy, family history of diabetes, hospitalization pre-delivery, gestational age at last prenatal weight, gestational age at OGTT, mean arterial pressure at OGTT, and maternal height.
