Mean weight SDSs in 5 milk-feeding groups adjusted for maternal education, smoking in pregnancy, and parity measured at 14 ages between birth and 10 y of age. Adjusted means by age are shown for the following feeding groups: breast milk (n = 95–136) (breastfed), <600 mL formula milk/d (n = 403–572) (formula low), ≥600 mL formula milk/d (n = 132–211) (formula high), <600 mL cow milk/d (n = 46–72) (cows low), and ≥600 mL cow milk/d (n = 42–67) (cows high).
