GWG: gestational weight gain; preg: pregnancy;
BMI: body mass index.
*Adjusted for infant sex, treatment group, recruitment site, weeks of gestation at delivery; 6-month analyses also adjusted for breastfeeding.
**Adjusted for infant sex, treatment group, recruitment site, weeks of gestation at delivery, and total maternal gestational weight gain; 6-month analyses also adjusted for breastfeeding.
Overall omnibus test at birth: F = 3.0; P =  0.004 (with GWG: F = 5.6; P  =  0.0001); at 6 months: F = 4.1; P  =  .0001 (with GWG: F = 3.9; P  =  .0001).
