Background The objective of our study was to examine whether outpatient respiratory morbidities in infants with bronchopulmonary dysplasia (BPD) are influenced by the human milk consumption. Methods Caregivers of subjects recruited from a BPD clinic completed questionnaires regarding breast milk intake and respiratory outcomes. Results One‐hundred eighty‐eight caregivers completed the questionnaire. Of these, 173 (92.0%) reported that the child received some breast milk. Infants who received breast milk for fewer months were more likely to be non‐white, and have a lower household income, public insurance, and secondhand smoke exposure. A longer receipt of breast milk was associated with reduced likelihoods of emergency department visits, systemic steroid courses, and cough or chest congestion, and a trend towards a lower risk of re‐hospitalizations. Conclusions Longer duration of breast milk intake was associated with markers of higher socio‐economic status, and reduced likelihood of acute and chronic respiratory morbidities among preterm infants with bronchopulmonary dysplasia.

Objective To identify factors associated with cessation of human milk prior to NICU discharge for infants diagnosed with bronchopulmonary dysplasia (BPD). Study Design Participants were recruited from the Johns Hopkins BPD Clinic between January 2016 and October 2018. Clinical and demographic characteristics were analyzed based on whether participants stopped human milk before or after NICU discharge. Results Of the 224 infants included, 109 (48.7%) infants stopped human milk prior to discharge. The median duration of human milk intake was less for infants who stopped prior to discharge compared to those who continued after discharge (2 vs 8 months, p<0.001). In multivariate regression analysis, pulmonary hypertension (OR: 2.90; p=0.016), public insurance (OR: 2.86; p<0.001), and length of NICU admission (OR: 1.26 per additional month; p=0.002) were associated with human milk cessation prior to NICU discharge. Conclusion Infants with BPD who have severe medical comorbidities and markers of lower socioeconomic status may be at higher risk for earlier human milk discontinuation.
