The purpose of this study is to test the feasibility of measuring body composition by air displacement plethysmography (ADP) in rapidly growing, medically stable late gestation [32-35 weeks post-menstrual age (PMA)] premature infants.

Full Term Infants
Infants born between 37 4/7 weeks and 42 3/7 weeks gestation.
Preterm Infants
Infants born between 32 4/7 weeks and 35 3/7 weeks gestation.

Detailed Description:
  1. To assess the feasibility of measuring body fat deposition by ADP in medically stable late gestation (32-35 weeks), premature infants during a period of rapid postnatal growth.
  2. To test the relationship between %BF by ADP to %BF by DXA, as well as characterize the relationship between these fat measures with bone measures by quantitative ultrasound and serum levels of insulin, IGF-1, IGF binding proteins, adiponectin and leptin.
  3. To perform inter- and intra-rater testing of anthropometric, ultrasound, and ADP measurements.
  4. Compare growth, body composition and bone strength between infants born preterm to infants born full term.
