At 2 years, the anthropometrics were similar for children randomized to donor milk or preterm formula in early infancy. Patterns of growth between discharge and follow-up differed by early infancy diet. There was a greater weight Z-score increase between discharge and follow-up for children randomized to donor milk than formula. Donor milk appears to be non-inferior to preterm formula with respect to growth at 2 years for children born extremely preterm. Policies and practices that facilitate parental milk provision and donor milk availability are needed for infants born extremely preterm.
Brumbaugh et al. (Mon,) studied this question.
