AbstractStudied the possible relationship between the growth rate of children who are breastfed, and the level of protein, fat, insulin-like growth factor-1 (IGF-1), ghrelin, leptin, adiponectin in breast milk. Examined 71 pair – a mother and a healthy child, who is breastfed. All infants were divided into 3 groups: low, normal and high weight gain. Daily breast milk intake, the level of fat, protein and hormones proteins – regulators of energy homeostasis (adiponectin, grelin, IGF-1 and leptin) in breast milk were measured at 1, 2 and 3 months of lactation. It was found that daily breast milk consumption was higher in the group of infants with high weight gain and the content of protein and fat in it did not differ in three groups. Total daily consumption of protein and fat with breast milk was higher in groups of infants with high weight gain. There was significantly higher IGF-1 level and the tendency to higher grelin level in breast milk of mothers of infants with higher weight gain. The possible link of breast milk hormones with growth velocity of breast-fed infants is discussed.
