Beunders VAA, Roelants JA, Hulst JM, et al. - Researchers conducted this prospective cohort study to explore the connection between postnatal weight gain during three different timeframes (NICU-stay, level-II hospital stay and at home) and body composition at 2 and 6 months corrected age in infants born very preterm (< 30 weeks of gestation). Of the 120 infants recruited in the research, body composition was measured in 103 (86%) at 2 months and in 92 (77%) at 6 months. Weight gain in various timeframes after preterm birth is correlated with distinct parameters of body composition in infancy, with weight gain at home being most closely related to fat mass.
