Associations between growth and childhood body composition in very preterm, late preterm and term children

To determine how gestational age at birth and postnatal growth relate to body composition in childhood. We calculated conditional growth (birth-2 years, 2 years-6 years) and measured body composition at 2 and 6 years using bioelectrical impedance in cohorts of New Zealand children born very preterm (VPT; 23-31 weeks), late preterm (LPT; 35-
