Predicted infant weight (A) and length (B) at 24 wk for varying maternal BMI levels in BAN mother-infant pairs included in the primary analysis of the effects of maternal weight loss on infant growth. Predicted curves from linear regression models containing infant initial anthropometric measurement, maternal weight loss from 2 to 24 wk, maternal BMI at 2 wk postpartum, and an interaction term between maternal weight loss and BMI. Weight gain: boys, n = 673; girls, n = 633. Length gain: boys, n = 667; girls, n = 632. BAN, Breastfeeding, Antiretrovirals, and Nutrition.
