Summary

Exclusively breastfed preterm infants showed significant weight gain, comparable to intrauterine growth rates. These findings highlight the effectiveness of breastfeeding for low birth weight infants post-discharge.

Area of Science:

  • Neonatology
  • Pediatric Nutrition
  • Infant Growth and Development

Background:

  • Preterm infants, particularly those with low birth weight, require careful monitoring for optimal growth post-discharge.
  • Exclusive breastfeeding is recommended for infants, but its impact on the growth of preterm infants after special care nursery discharge needs specific analysis.

Purpose of the Study:

  • To prospectively analyze the weight gain of exclusively breastfed preterm low birth weight infants over the first 24 weeks of life.
  • To compare growth patterns based on initial birth weight categories and gestational age.

Main Methods:

  • Prospective analysis of weight gain in 355 preterm low birth weight infants exclusively breastfed after discharge.
  • Categorization of infants by birth weight (1000-1500g and 1501-2000g) and gestational age (32, 34, 36 weeks).

  • Calculation of growth velocity and time to double/triple birth weight.

    • Main Results:

    • Infants weighing 1000-1500g doubled birth weight by 10 weeks and tripled by 18 weeks (growth velocity 20-30 g/day).
    • Infants weighing 1501-2000g doubled birth weight by 12 weeks and tripled by 16 weeks (growth velocity 30 g/day up to 11 weeks, then 20 g/day).
    • Infants born at 32 weeks showed a 3-week growth delay followed by catch-up, while those born at 34-36 weeks had a 2-week delay and similar catch-up, achieving intrauterine growth rates.

    Conclusions:

    • Exclusive breastfeeding supports significant weight gain in preterm low birth weight infants after discharge.
    • Growth patterns are influenced by initial birth weight and gestational age, with a notable catch-up phase observed.
    • Attained weights were comparable to intrauterine growth rates, underscoring the efficacy of breastfeeding in this population.
