Comparison of Breast Milk Compositions Among Mothers Delivering Small-for-Gestational Age, Appropriate-for-Gestational Age, and Large-for-Gestational Age Infants.

Objectives: The aim of this study was to compare the breast milk compositions of mothers who delivered babies in three different birth weight categories.

Materials And Methods: We collected 75 breast milk samples from mothers of small-for-gestational age (SGA), appropriate-for-gestational age (AGA), and large-for-gestational age (LGA) term infants (25 per group) on the 11th-28th day postpartum using a manual or electric breast pump. Homogenized samples were analyzed using a mid-infrared human milk analyzer within 2 hours of collection, and protein, carbohydrate (CHO), fat, and energy levels were compared.
