Daily feeding regimens, including mother's own milk (MOM), human donor milk, and formula; daily growth; acute and chronic pain/stress were documented during NICU. NICU Network Neurobehavioral Scale (NNNS) (36 to 38 postmenstrual age), and Bayley Scales of Infant and Toddler Development (Bayley) Edition III (1 and 2 years of CA) were measured.<h4>Results</h4>Between week 9 to 16 after birth, only females showed a positive association between growth z-score and proportion of MOM intake before week 8 (<i>p<Frontiers in pediatrics1523952https://www.ebi.ac.uk/biostudies/studies/S-EPMC11985779biostudies-literatureSex-differences in Mothers' own milk and neurodevelopmental outcomes in preterm infants.PMC11985779Quinn TChen JChen MHCong XLi AZhao TMatson APTaylor SNXu WChang XfalseSex-differences in Mothers' own milk and neurodevelopmental outcomes in preterm infants.<h4>Objective</h4>To identify sex-specific feeding patterns and associations with growth and neurodevelopment in preterm infants during NICU through 2 years of corrected age (CA).<h4>Methods</h4>A cohort study was conducted with 216 preterm infants (gestational age 28 0/7 to 32 0/7 weeks).
