title: [Quality of growth in preterm infants assessed at term equivalent age: a pilot study].
abstract: BACKGROUND
  The American Academy of Pediatrics (AAP) recommends that preterm infants' growth duplicates fetal growth rates and that body composition replicates in utero body composition. Aim ofthe study was to compare the total body fat mass between preterm infants assessed at term and full-term newborns.
  
  
  METHODS
  A prospective observational study was conducted. Forty-five preterm infants (mean (SD) gestational age: 30,1 (2.3) weeks; birth weight: 1125 (280) g), and 40 full term (mean (SD) 38.5 (1.2) weeks, 3203 (385) g, breast fed infants underwent assessment of growth and body composition by means of an air displacement system at term adjusted-age and on day 3 of life, respectively. A T test was used to compare % fat mass between preterm and term infants.
  
  
  RESULTS
  Weight, length and head circumference were smaller in the preterm group assessed at term adjusted-age as compared to the term group. Mean (SD) percentage of fat mass in preterm infants was significantly higher as compared to term infants [14.5 (4.3) vs 7,6 (3.6), P < 0.0001].
  
  
  CONCLUSIONS
  Our data demonstrate that preterm infants are at risk of developing an increased adiposity in addition to postnatal growth retardation.
