Abstract Objectives To incorporate assessment of body composition in the routine care of preterm infants to guide feeding practices before and after hospital discharge. Methods Very preterm infants with gestational ages between 29 and 32 weeks of gestation were included. Infants with gastrointestinal or neurologic malformations and terminal illness needing to limit or withhold support were excluded. All study participants were eligible for serial assessments of body composition between birth and 32 weeks PMA, at 36 weeks PMA or hospital discharge, and at 3 months of corrected age. Infants randomly assigned to the intervention group had the information about infant body composition available to the clinicians caring for them (including reference data). Infants randomly assigned to the control group also underwent serial assessments, but this information on infant body composition was not shown to the clinicians caring for them. The primary outcome was % body fat (%BF) estimated by air displacement plethysmography. Results Fifty very preterm infants were randomized. Mean birthweight of study participants was 1387 g +/– SD 283 and median gestational age at birth was 30 weeks (IQR: 30 – 31). Sociodemographic characteristics did not differ between groups. Mean %BF between birth and 32 weeks PMA (n = 45) was 6 +/– 4, mean %BF at 36 weeks PMA (n = 35) was 14 +/– 4, and mean %BF at 3 months of corrected age (n = 25) was 20 +/– 4. Mean differences in %BF between the intervention group and the control group were not statistically significant at 36 weeks PMA (−0.8) or 3 months corrected age (−1.2). Similarly, feeding practices during hospitalization did not differ between groups. Growth outcomes did not differ between groups. Conclusions Serial assessments of body composition at birth, 36 weeks PMA, and 3 months corrected age in very preterm infants show increased %BF in both intervention and control groups without an apparent influence of the intervention on feeding practices. While 36 weeks PMA has been a common assessment point for research purposes, body composition assessments may need to be done at earlier intervals in order to make meaningful clinical changes to the infant diet in order to affect body composition later in infancy.

AbstractThe development of head shape and volume may reflect neurodevelopmental outcome and therefore is of paramount importance in neonatal care. Here, we compare head morphology in 25 very preterm infants with a birth weight of below 1500 g and / or a gestational age (GA) before 32 completed weeks to 25 term infants with a GA of 37–42 weeks at term equivalent age (TEA) and identify possible risk factors for non-synostotic head shape deformities. For three-dimensional head assessments, a portable stereophotogrammetric device was used. The most common and distinct head shape deformity in preterm infants was dolichocephaly. Severity of dolichocephaly correlated with GA and body weight at TEA but not with other factors such as neonatal morbidity, sex or total duration of respiratory support. Head circumference (HC) and cranial volume (CV) were not significantly different between the preterm and term infant group. Digitally measured HC and the CV significantly correlated even in infants with head shape deformities. Our study shows that stereophotogrammetric head assessment is feasible in all preterm and term infants and provides valuable information on volumetry and comprehensive head shape characteristics. In a small sample of preterm infants, body weight at TEA was identified as a specific risk factor for the development of dolichocephaly.
