OBJECTIVE: To investigate the association of leptin, adiponectin, and ghrelin in breast milk with the weight growth velocity of infants with exclusive breastfeeding.
METHODS: A total of 67 full-term singleton infants who received regular child care and exclusive breastfeeding and their mothers were enrolled. The nutritional status was evaluated based on the measurements of body weight and body length (underweight, growth retardation, emaciation, overweight, and obesity). Z score was used to calculate growth velocity, and according to the ΔZ score, the infants were divided into poor growth group, low growth velocity group, and normal growth velocity group. Mature breast milk samples were collected from their mothers, and ELISA was used to measure the levels of leptin, adiponectin, and ghrelin.
RESULTS: The emaciation group had a significantly lower level of leptin in breast milk than the non-emaciation group (P<0.05), and the overweight/obesity group had a significantly lower level of adiponectin than the non-overweight/obesity group (P<0.05). The correlation analysis showed that the level of ghrelin in breast milk was positively correlated with Z score of current body weight and ΔZ score compared with birth weight (rs=0.280 and 0.290 respectively; P<0.05). The regression analysis showed that the level of ghrelin in breast milk was an important influencing factor for the Z score of body weight (β=0.161, P<0.05).
CONCLUSIONS: Various active constituents in breast milk, including leptin, adiponectin, and ghrelin, may regulate the growth and development of infants to a certain degree, but long-term studies and observation are needed to investigate their association with offspring growth and development and the health-promoting effect of breast milk on offspring.
