Key Points

To investigate the growth trajectories of very preterm appropriate-for-gestational-age infants from term-equivalent age to six years.
Longitudinal observational study design
Analysis of growth data from birth to six years
Comparison of head size and physical growth metrics
Very preterm infants demonstrate slower growth compared to full-term peers
Infants born before 25 weeks exhibit smaller head sizes
Delayed growth persists into early childhood, affecting developmental outcomes

Implication

Observational study examines growth in very preterm infants, indicating potential brain development concerns.

Abstract

Many extremely preterm infants grow more slowly than expected well into early childhood. Babies born earlier in pregnancy show more delayed physical growth across all measures. Infants born before 25 weeks may have a smaller head size, raising concerns for brain development.
