Mother's own milk and bronchopulmonary dysplasia in appropriate for gestational age preterm infants

Objective: To evaluate the association between mother's own milk (MOM) and bronchopulmonary dysplasia (BPD) in appropriate for gestational age (AGA) preterm infants <32 weeks. Methods: Clinical data of AGA preterm infants (24+0/7-31+6/7 weeks) were reviewed. Infants with >= 66% of cumulative prescribed enteral volumes as MOM from birth to 36 weeks were allocated to the high provision of MOM group (H-MOM), whereas those with <66% were assigned to the low provision of MOM group (L-MOM). Multiple regressions were used to assess the association of H-MOM with BPD and oxygen saturation to fraction inspired oxygen ratio (SFR) at 36 weeks. Results: A total of 1041 infants met the inclusion criteria, with a median provision of cumulative enteral nutrition volumes of 5721 (IQR 2616) mL/kg. Among them, 517 (49.7%) were H-MOM and 524 (50.3%) L-MOM infants. H-MOM showed a reduction in the incidence of BPD to 31.6% compared to L-MOM infants. H-MOM had a lower risk of BPD than L-MOM infants after the adjustment for gestational age, sex, cesarean section, mean SFR at the first hours of life, surfactant administration, patent ductus arteriosus, sepsis, prolonged ventilatory supports/oxygen exposure, and cumulative energy intakes from birth to 36 weeks [aOR: 0.613, p = 0.047]. H-MOM was also associated with a lower risk of SFR in the first quartile at 36 weeks [aOR: 0.616, p = 0.028] than L-MOM. Conclusion: A high provision (>= 66%) of enteral volume as MOM from birth to 36 weeks is associated with a reduced risk of both BPD and low SFR at 36 weeks in AGA preterm infants <32 weeks.
