Insights

Exclusive breastfeeding significantly benefits preterm infants (28-33 weeks gestation) by promoting weight gain and reducing feeding intolerance and necrotizing enterocolitis (NEC). Formula feeding did not show these advantages in this vulnerable group.

Area of Science:

  • Neonatal Nutrition
  • Pediatric Gastroenterology
  • Infant Development

Background:

  • Preterm infants require specialized nutritional support to optimize growth and minimize complications.
  • Breastfeeding offers numerous benefits, but its specific impact on very preterm infants across different gestational ages requires detailed investigation.

Purpose of the Study:

  • To evaluate the efficacy of exclusive breastfeeding versus formula feeding in preterm infants.
  • To compare the effects on weight gain, key laboratory markers, and the incidence of feeding intolerance, necrotizing enterocolitis (NEC), and retinopathy of prematurity (ROP).

Main Methods:

  • A cohort of 639 preterm infants (28+3-36+6 weeks gestation) were divided into exclusive breastfeeding (n=237) and formula feeding (n=402) groups.
  • Outcomes assessed included weight gain, albumin (Alb) and alkaline phosphatase (ALP) levels, feeding intolerance, NEC, and ROP incidence.

Main Results:

  • In infants aged 28-30 weeks, breastfeeding led to faster weight gain, lower NEC rates, higher ALP, and lower Alb levels compared to formula.
  • For infants aged 31-33 weeks, breastfeeding showed faster weight gain, reduced feeding intolerance, shorter hospital stays, and higher ALP levels.
  • No significant differences were observed between groups for infants aged 34-36 weeks.

Conclusions:

  • Exclusive breastfeeding is crucial for preterm infants (28-33 weeks gestation), enhancing weight gain and decreasing feeding intolerance and NEC.
  • The benefits of breastfeeding are most pronounced in the earlier preterm groups, highlighting the importance of tailored nutritional strategies.
