Growth increments in preterm low risk infants.

Area of Science:

• Neonatalogy
• Developmental Pediatrics
• Pediatric Growth Studies

Background:

• Preterm infants face unique growth challenges.
• Understanding early growth velocity is crucial for identifying potential developmental issues.
• Factors like fetal acidosis and neurodevelopmental disorders can impact infant growth trajectories.

Purpose of the Study:

• To analyze growth velocity in low-risk, vaginally born preterm infants over four years.
• To investigate the influence of gestational age, fetal acidosis, neurodevelopmental disorders, sex, feeding, and maternal education on infant growth.
• To identify early growth indicators for at-risk preterm infants.

Main Methods:

• Longitudinal follow-up of 35 low-risk preterm infants for four years.
• Weekly measurements of weight, length, and head circumference.
• Statistical analysis of growth increments in relation to various influencing factors.

Main Results:

• A significant weight difference was observed between infants with and without neurodevelopmental disorders in the first 7 months.
• Infants with fetal acidosis or neurodevelopmental disorders exhibited lower initial weight and head circumference increments but higher weight increments between 3-7 months.
• Breastfed infants and males showed higher weight increments in early infancy; females showed higher length increments.

Conclusions:

• Early growth patterns in preterm infants can be influenced by fetal acidosis and neurodevelopmental status.
• Specific growth velocity changes during early infancy may serve as indicators for at-risk preterm populations.
• Maternal education and feeding methods also showed associations with infant growth increments.
