Insights
Achieving feeding milestones earlier in preterm infants is linked to better postnatal growth. Delays in feeding milestones correlate with slower growth and longer hospital stays for these vulnerable infants.
Area of Science:
- Neonatalogy
- Pediatric Nutrition
- Growth and Development
Background:
- Postnatal growth is critical for preterm infants.
- Feeding milestones are key developmental markers.
- Understanding the link between feeding and growth is essential for optimizing care.
Purpose of the Study:
- To investigate the association between feeding milestones and postnatal growth in preterm infants.
- To identify potential growth faltering risks related to feeding progression.
Main Methods:
- Retrospective analysis of 77 infants born before 32 weeks' gestation.
- Growth z-scores calculated at birth and discharge.
- Postnatal growth faltering (PGF) defined by significant z-score changes.
Main Results:
- 11.7% severe and 22% complex PGF observed.
- Infants born <28 weeks had higher PGF rates and feeding delays.
- Delayed enteral feeding correlated with slower growth and longer hospitalization.
Conclusions:
- Feeding milestones and postnatal growth are interconnected in preterm infants.
- Early achievement of feeding milestones may promote improved growth outcomes.
- Optimizing feeding strategies could enhance growth in this population.
Objective:
To examine the relationship between feeding milestones and the postnatal growth of preterm infants.
Study Design:
Retrospective study of 77 infants born <32 weeks' gestation. Growth variables at birth and discharge were converted to age- and sex-specific z-scores. Postnatal growth faltering (PGF) was defined as loss of >2 weight z-scores (severe) or simultaneous loss of >1 weight, length, and head circumference z-scores (complex).
Results:
The prevalence of severe and complex PGF was 11.7% and 22%, respectively. Infants <28 weeks' gestation experienced more PGF (severe: 22.2%; complex: 33.3%) and feeding delays. Older age at first and full enteral feeding, and longer transition from first to full enteral feeding, were associated with slower growth (All, p < 0.05). Feeding delays were associated with prolonged hospitalization (p < 0.05).
Conclusion:
Feeding milestones and postnatal growth are interrelated. Earlier attainment of feeding milestones may support more favorable growth outcomes in preterm-born infants.
