Insights

Complementary feeding (CF) strategies for very low birth weight (VLBW) infants show varied nutrient intake but similar growth outcomes. Standardized feeding increased iron and zinc, while parent-led feeding boosted protein, fat, and fatty acids.

Area of Science:

  • Neonatal nutrition
  • Infant growth and development
  • Pediatric gastroenterology

Background:

  • The complementary feeding (CF) period is crucial for nutrient intake in very low birth weight (VLBW) infants.
  • Optimal nutrition during CF supports growth and development in VLBW infants.

Purpose of the Study:

  • To compare nutrient intake and growth between a standardized, protocol-driven CF approach and a non-standardized, parent-led CF approach in VLBW infants.
  • To identify differences in nutritional intake and their potential impact on growth in VLBW infants.

Main Methods:

  • Comparison of two CF strategies in VLBW infants (<1500g birth weight).
  • Standardized group followed an age-dependent protocol using commercial baby foods.
  • Non-standardized group used parent-led feeding without restrictions; nutritional intake assessed via 3-day records.

Main Results:

  • Non-standardized group had higher intakes of protein, fat, arachidonic acid, and docosahexaenoic acid.
  • Standardized group showed higher iron and zinc intake from 6 months corrected age.
  • Despite nutritional differences, infant growth was similar between both CF strategy groups.

Conclusions:

  • Complementary feeding approaches significantly impact nutrient intake in VLBW infants.
  • Individualized CF strategies may be necessary to meet specific nutritional needs.
  • Further research can guide optimal feeding practices for VLBW infants.
