Male sex is an independent risk factor for poor neurodevelopmental outcome at 20 months' corrected age, in human milk-fed very preterm infants: a cohort study.

Objective: To determine associations between sex and neurodevelopmental outcomes in human milk-fed very preterm infants, adjusted to early measured nutrient intakes and other neonatal cofactors.

Methods: Consecutive inborn human milk-fed infants, with gestational age <33 weeks, were eligible. In-hospital energy and protein intakes have relied on measured human milk composition.
