Human Milk and Clinical Outcomes in Preterm Infants

The LOVE MOM cohort (Longitudinal Outcomes of VLBW Infants Exposed to Mothers' Own Milk; NIH: R010009; Meier PI) enrolled 430 infants with very low birth weight (VLBW) between 2008 and 2012 to study the impact of the dose and exposure period of MOM during hospitalization in the neonatal intensive care unit (NICU) on potentially preventable complications of prematurity and their associated costs. In this prospective study, MOM and formula feedings were calculated daily (mL), medical diagnoses for NICU morbidities (necrotizing enterocolitis [NEC], late-onset sepsis [sepsis], and bronchopulmonary dysplasia [BPD]) were confirmed independently by 2 neonatologists, and propensity scoring was used to analyze covariates. Neurodevelopmental outcome was measured for a subset of 251 LOVE MOM infants at 20 months of age, corrected for prematurity (CA). Data revealed a dose-response relationship between higher amounts of MOM received during critical NICU exposure periods and a reduction in the risk of NEC, sepsis, BPD, and their costs, as well as higher cognitive index scores at 20 months CA. MOM appears to function via different mechanisms during NICU exposure periods to reduce the risk of potentially preventable complications and their costs in VLBW infants. Institutions should prioritize the economic investments needed to acquire, store, and feed high-dose MOM in this population.
