ABSTRACT
OBJECTIVE:
This study aimed to evaluate body composition at the time of hospital discharge in very preterm infants following rapid transition to full enteral feeding. STUDYDESIGN:
We conducted a prospective, observational, cross-sectional study and included 105 preterm infants <32 gestational age or birth weight <1,500 g, born between April 2015 and December 2020, following rapid transition to full enteral feeding (≥140 mL/kg/day). Fat mass/total body mass (BF%) and fat-free mass (FFM) were measured at the time of hospital discharge using air displacement plethysmography.RESULTS:
Median and interquartile range (Q1-Q3) of gestational age at birth (GA) was 27.3 (26.1-28.7) weeks and birth weight 845 (687-990) g. Time to reach full enteral feeding was 5 (5-7) days. At 37.6 weeks (36.1-39.0) postmenstrual age (PMA), BF% was 17.0% (14.9-19.8) and FFM 2,161 g (1,966-2,432). BF% was not associated with GA, and not different between small and appropriate for gestational age infants. FFM was significantly lower in infants born small for gestational age.CONCLUSIONS:
Following rapid transition to full enteral feeding, FFM and BF% at discharge were similar to other preterm populations. BF% and FFM were not associated with GA at birth but with PMA at measurement. FFM was lower and BF% higher compared to term infants at birth, suggesting diminished parenchymal growth in preterm infants. Continued monitoring of body composition, metabolic health, and neurological development is needed to study long-term effects.Palavras-chave
