Insights

The method of introducing complementary feeding (CF) did not influence the occurrence of pediatric feeding disorders (PFD) in infants. This study found no significant differences in PFD rates across traditional, Baby-Led Introduction to Solids (BLISS), or mixed CF methods.

Area of Science:

  • Pediatric Nutrition
  • Infant Development
  • Clinical Trials

Background:

  • Complementary feeding (CF) introduction timing and methods are crucial for infant development.
  • Pediatric feeding disorders (PFD) can impact a child's health and well-being.
  • Understanding the relationship between CF methods and PFD is essential for early intervention.

Purpose of the Study:

  • To determine if the method of complementary feeding (CF) introduction is associated with pediatric feeding disorders (PFD).
  • To investigate PFD development in infants during the first year of life based on different CF approaches.

Main Methods:

  • A randomized clinical trial involving 128 mother-child pairs.
  • Intervention groups received traditional, Baby-Led Introduction to Solids (BLISS), or mixed CF methods starting at 5.5 months.
  • Pediatric feeding disorders (PFD) were screened at 12 months using the Brazilian Child Feeding Scale (EBAI).

Main Results:

  • Pediatric feeding disorders (PFD) were identified in 12.5% of infants across all groups.
  • The prevalence of PFD was 3.9% for the traditional method, 7% for BLISS, and 1.6% for the mixed method.
  • No statistically significant differences in PFD were observed between the different complementary feeding (CF) methods.

Conclusions:

  • The method used for complementary feeding (CF) introduction did not significantly influence the development of pediatric feeding disorders (PFD).
  • Infant feeding practices, regardless of method, showed generally adequate and favorable responses in the study sample.
