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 = 3.4; P = 0.001 (with GWG: F = 3.6; P = 0.0001); at 6 months: F = 3.6; P  =  .001 (with GWG: F = 3.3; P = 0.001).
