Gestational age-specific sex difference in neurological outcomes of very low birth weight preterm infants-a nationwide study.

ABSTRACT: This is a population-based study from the Korean Neonatal Network (KNN) for very low birth weight infants (VLBWIs) born at 23⁺⁰ and 31⁺⁶ weeks of gestation between 2013 and 2019. This study aims to evaluate the effect of sex on neurological outcomes at 18-24 months corrected age, stratified with gestational age (GA) in VLBWIs. A total of 1,829 infants (15.7%) who completed Bayley Scales of Infant and Toddler Development, third edition (BSID-III) assessments at 18-24 months corrected age were included and were further stratified into three GA groups: 23⁺⁰ to 25⁺⁶ weeks, 26⁺⁰ to 28⁺⁶ weeks, and 29⁺⁰ to 31⁺⁶ weeks. The primary outcomes were the BSID-III composite scores and neurodevelopmental delay defined
