*Odds ratios for OGTT measures are for an increase in glucose level of 1 SD (7.99 mg/dl for FPG, 30.84 mg/dl for 1-h glucose, and 23.08 mg/dl for 2-h glucose) and are adjusted for maternal age, race/ethnicity, parity, prepregnancy BMI, gestational weight gain, infant sex, and gestational age at OGTT.
