^*Composite OGTT, area under the curve (mg/dL×Hr) – Composite of fasting, 1, 2, and 3 hour OGTT values.

Variables included in models were maternal glucose, maternal age, race/ethnicity, prepregnancy maternal BMI, maternal weight gain, neonatal factors of large for gestational age (LGA), small for gestational age (SGA), fat mass, and elevated cord c-peptide level, gender, and age of the child at exam. HOMA-IR, sum of skin folds, and subscapular to triceps skinfold ratios were log-transformed.
