| Popis: | To determine the effects of length of gestation and sex on infant body composition, air displacement plethysmography was performed in forty-six full-term neonates at 3 d of life and during the week prior to hospital discharge in 180 preterm neonates. Fat mass, as a percentage of body weight, was higher in preterm than in term infants (13·4 (sd4·2)v. 10·1 (sd3·7) %, respectively;P= 0·001). The absolute amount of fat mass did not differ between preterm and full-term newborns (323 (sd126)v. 335 (sd138) g;P= 0·58), whereas lean body mass was lower in preterm than in term infants (2055 (sd280)v. 2937 (sd259) g, respectively;Psd3·7)v. 9·0 (sd3·3) %, respectively;P= 0·047), whereas we did not observe any sex difference in preterm infants (13·5 (sd4·1)v. 13·4 (sd4·3) %;P= 0·89). Our data suggest that by the time they are discharged from hospital: (1) preterm infants have a higher percentage of body fat than term neonates and (2) this is presumably due to a lesser accretion in lean body mass in the first few weeks of extra-uterine life, particularly in boys. |
