Enhancing Interpretation of One-Time Body Composition Measurement at Near-Term Gestation in Preterm Infants: An Exploratory Study.

In preterm infants, longitudinal growth patterns have a stronger association with clinical outcomes than cross-sectional metrics. For qualitative growth, a one-time body composition measurement at near term is common, and here we explore the potential use of a novel estimated longitudinal body composition metric (adjusted fat-free mass deficit) using birth anthropometrics. KEY POINTS: · Longitudinal growth patterns are better linked with clinical outcomes in preterm infants.

Effect of parenteral nutrition duration on patterns of growth and body composition in very low-birth-weight premature infants.

Background: Parenteral nutrition (PN) is essential to support premature infants' growth and varies with enteral nutrition (EN) advancement rates. Data on PN duration's impact on premature infants' growth are limited. The aim of this multicenter observational study was to determine the effect of early PN duration on body composition at term corrected gestational age (CGA) in very low-birth-weight (VLBW) premature infants.

Infant body composition assessment in the neonatal intensive care unit (NICU) using air displacement plethysmography: Strategies for implementation into clinical workflow.

Nutritional management is integral to infant care in the neonatal intensive care unit (NICU). Recent research on body composition that specifically evaluated fat and fat-free mass has improved our understanding of infant growth and nutritional requirements. The need for body composition monitoring in infants is increasingly recognized as changes in fat mass and fat-free mass associated with early growth can impact clinical outcomes.
