Predicted Infant Birthweight using model 1.
Results pictured for mother’s age 26, gestational age 38 weeks, 11.3 kg (25 lbs) weight gain, averaged over effects of infant sex, prenatal care, smoking, hypertension, first born, and availability of prenatal information at the 50th (A), 75th (B), and 90th (C) quantile.
Table 2.
Model One: Predicted infant birth weights (gm) and birth weight differences (with 95% CI) at a maternal pre-pregnancy body mass index of 25, 30, 35, and 45 kg/m2 in NHW and NHB with and without diabetes.

Predicted Infant Birthweight using model 2.
Results pictured for mother’s age 26, gestational age 38 weeks, prepregnancy BMI 30, averaged over effects of infant sex, prenatal care, smoking, hypertension, first born, and availability of prenatal information at the 50th (A), 75th (B), and 90th (C) quantile.
Table 3.
Model Two: Predicted infant birth weights (gm) and birth weight differences (with 95% CI) at gestational weight gain (GWG) of 9, 13.5, 18, and 30 kg in NHW and NHB with and without diabetes.

Effect of GDM on Birthweight by Quantile.
Effect of GDM on birthweight in Model One (A) and Model Two (B). The figure presents the additional birthweight associated with a mother having GDM in NHW and NHB for a maternal BMI of 30 or 35 (A) or gestational weight gain of 13.5 or 18 kg (B).
