Insights

Extremely premature neonates show improved postnatal growth but remain shorter than controls. Head growth declines, increasing microcephaly risk by age five, highlighting the need for long-term monitoring.

Area of Science:

  • Neonatalogy
  • Pediatric Growth and Development
  • Public Health

Background:

  • Increasing survival rates of extremely premature neonates necessitate understanding their long-term health outcomes.
  • Growth patterns and risk factors for later disorders in this population require thorough evaluation.

Purpose of the Study:

  • To prospectively assess anthropometric parameters in children born extremely prematurely.
  • To identify growth trajectories and potential health risks in this vulnerable group.

Main Methods:

  • Anthropometric measurements (height, head circumference, waist/hip circumference, skinfolds) were taken at 2 and 5 years.
  • Study included 72 neonates born between 22-25+6 weeks gestation (Group I) and 85 neonates born between 26-27+6 weeks gestation (Group II).
  • Comparison made with a control population.

Main Results:

  • Both groups exhibited catch-up postnatal growth, but height remained significantly lower than controls at 2 and 5 years (P < 0.01).
  • A decline in head growth was observed between ages 2 and 5, leading to decreased head circumference standard deviation scores (SDS).
  • Microcephaly (HC < -2 SD) increased, affecting 18% in Group I and 11.7% in Group II by age five. Waist/hip circumferences and skinfolds showed no significant differences between groups at age five.

Conclusions:

  • Long-term follow-up of extremely premature neonates is crucial for understanding growth patterns.
  • Assessment of growth parameters, including adiposity, aids in identifying risk factors for adult-onset diseases.
  • Early identification of growth deviations like microcephaly is essential for timely intervention.
