1347 Body Composition at 32–36 Weeks Corrected Age in Infants Born Before 32 Weeks Gestation

Background Preterm infants at term equivalent age are smaller than full term infants with a higher fat mass. The aim of this study was to determine if alterations in adiposity are already evident at 32–36 weeks corrected age (CA). Methods Preterm babies (n=21) born before 32 weeks gestation were studied between 32 and 36 weeks CA using the PEAPOD Infant Body Composition System to assess % body fat. The data were compared with a second group of babies (n=17) born at 32–36 weeks gestation. Results Mean % body fat at 32–36w CA in infants born < 32w was 14.1±5.8 (mean ± SD) and this was significantly higher than % body fat in infants born at 32–36 weeks (7.9±4.5, P
