Summary
Preterm infants experienced poor weight gain but accelerated head growth. Breast milk intake positively impacted head growth, while illness severity negatively affected weight gain in premature babies.
Area of Science:
- Neonatalogy and Perinatal Medicine
- Pediatric Growth and Development
- Neurodevelopmental Outcomes
Background:
- Poor growth in preterm infants, especially head growth, is linked to neurodevelopmental issues.
- Understanding growth patterns is crucial for improving outcomes in premature babies.
Purpose of the Study:
- To assess weight gain and head growth in preterm infants from birth to term.
- To investigate the influence of breast milk intake and illness severity on growth.
Main Methods:
- Studied infants born at or before 32 weeks gestation, assessed up to 37 weeks postmenstrual age.
- Measured weight and head circumference (HC) as standard deviation scores (SDS).
- Quantified illness severity (%L1IC) and breast milk exposure (%BM) relative to total days.
Main Results:
- Infants showed significant weight decline (SDS from -0.31 to -1.32) but significant head growth (SDS from -0.52 to -0.03).
- Higher illness severity (%L1IC) correlated with poorer weight gain (SDSG).
- Greater breast milk intake (%BM) correlated with improved head growth (SDSG).
Conclusions:
- Accelerated postnatal head growth may indicate catch-up from intrauterine constraints.
- Breast milk may promote postnatal head growth, suggesting a need for optimized feeding strategies.
- Illness severity significantly impacts weight gain in preterm infants.
