Percent Body Fat Content Measured by Plethysmography in Infants Randomized to High- or Usual-Volume Feeding after Very Preterm Birth

J Pediatr. 2021 Mar;230:251-254.e3. doi: 10.1016/j.jpeds.2020.11.028. Epub 2020 Nov 25.


We measured percent body fat by air-displacement plethysmography in 86 infants born at <32 weeks of gestation randomized to receive either high-volume (180-200 mL/kg/day) or usual volume feeding (140-160 mL/kg/day). High-volume feeding increased percent body fat by ≤2% at 36 weeks of postmenstrual age (within a predefined range of equivalence). TRIAL REGISTRATION: NCT02377050.

Keywords: anthropometric measurements; body composition; body fat; clinical trial; neonatal adiposity; postnatal growth; premature infants.
