Insights

Early intervention improves motor development in preterm infants. This support helps mitigate developmental delays, leading to better functional outcomes for high-risk infants.

Area of Science:

  • Neonatal research
  • Developmental pediatrics
  • Neuroscience

Background:

  • Early developmental intervention leverages neuroplasticity to improve outcomes in preterm infants.
  • This study examines early intervention's impact on neurodevelopment in preterm infants without severe brain injury.

Purpose of the Study:

  • To investigate the relationship between early intervention and neurodevelopmental outcomes in early childhood among preterm infants.
  • To assess the effectiveness of early intervention in mitigating motor developmental delays.

Main Methods:

  • Prospective cohort study of very-low-birth-weight infants (23+0-32+6 weeks' gestation) from the Korean Neonatal Network.
  • Neurodevelopmental evaluation at 18-24 months corrected age and 33-45 months chronological age using standardized tests.
  • Early intervention defined as initiation of motor or language therapy before 18-24 months corrected age.

Main Results:

  • Of 1797 infants, 518 (28.8%) received early intervention.
  • Infants receiving early intervention had lower gestational age and higher complication rates.
  • Early intervention was associated with a reduced risk of motor developmental delays over time (aOR 0.669).

Conclusions:

  • Early intervention is linked to more favorable motor outcomes in preterm infants.
  • Timely support is crucial for high-risk preterm infants.
  • Early intervention can help offset developmental impacts of preterm complications.
