Summary
Preterm infants born between 26-36 weeks show catch-up growth postnatally. Their growth patterns normalize, mirroring intrauterine growth curves by 40-42 weeks corrected age.
Area of Science:
- Neonatalogy
- Pediatric Growth and Development
Context:
- Preterm infants (26-36 weeks gestation) require monitoring for optimal growth.
- Postnatal growth trajectories often differ from intrauterine patterns.
Purpose:
- To establish growth curves for appropriate-for-gestational-age preterm infants.
- To compare postnatal growth with intrauterine growth curves.
Summary:
- 141 preterm infants were monitored weekly for weight, height, and head circumference until 42 weeks corrected postmenstrual age.
- Third-degree polynomial functions were used to model growth curves.
- Postnatal growth curves were similar to intrauterine curves at 40-42 weeks corrected age.
- A catch-up growth pattern was observed in the early postnatal period.
Impact:
- Provides normative growth data for preterm infants.
- Informs clinical management and nutritional support for premature neonates.
- Highlights the catch-up phenomenon in preterm infant development.
