Intake of Own Mother’s Milk during the First Days of Life Is Associated with Decreased Morbidity and Mortality in Very Low Birth Weight Infants during the First 60 Days of Life

BACKGROUND: The incidence of necrotizing enterocolitis (NEC) and possibly also of sepsis is lower in preterm infants fed their own mother's milk (hereafter 'mother's milk') compared with formula-fed infants. It is unclear whether this is caused by the protective properties of breast milk or by the absence of cow's milk. Especially in early life, mother's milk is often unavailable to preterm infants, while minimal enteral nutrition is initiated immediately. OBJECTIVES: To determine whether there is an association between intake of mother's milk during the first days of life and the combined outcome of sepsis, NEC and death over a prolonged period. METHODS: Retrospective study in infants with a birth weight 50% of the total intake was mother's milk (HR = 0.37, 95% CI 0.22, 0.65). CONCLUSION: The type of enteral nutrition during the first 10 days of life is associated with the risk of NEC, sepsis and/or death during the first 60 days of life.
