[Correlation between serum IGF-1 level and feeding difficulties in preterm infants]

Area of Science:

• Neonatal research
• Pediatric endocrinology
• Infant nutrition

Context:

• Preterm infants often experience feeding difficulties, impacting growth and development.
• Serum insulin-like growth factor-1 (IGF-1) plays a crucial role in fetal and neonatal growth.
• Understanding factors contributing to feeding difficulties is vital for optimizing infant care.

Purpose:

• To investigate the association between serum IGF-1 levels and the occurrence of feeding difficulties in preterm infants.
• To identify IGF-1 as a potential biomarker for predicting feeding challenges in this vulnerable population.

Summary:

• A retrospective study analyzed 200 preterm infants, measuring serum IGF-1 levels within 24 hours of birth.
• Infants experiencing feeding difficulties exhibited significantly lower serum IGF-1 levels compared to controls (28±4 ng/mL vs. 63±8 ng/mL, P<0.05).
• Multivariate analysis identified decreased IGF-1 levels as a risk factor for feeding difficulties, alongside asphyxia and delayed feeding initiation.

Impact:

• Findings suggest that low serum IGF-1 levels are correlated with increased risk of feeding difficulties in preterm infants.
• This research may inform targeted interventions to support nutritional management and improve outcomes for preterm neonates.
• Highlights the potential of IGF-1 monitoring in neonatal intensive care units.
