AI Article Synopsis

  • The study aimed to create a predictive model for whether infants born preterm or with low birth weight were fed their mother's own milk (MOM) at discharge, focusing on social determinants of health (SDOH) and maternal-neonatal factors.
  • It analyzed data from 986 neonates at an inner-city hospital, revealing that feeding MOM was less common among non-Hispanic Black mothers compared to Hispanic mothers, a trend that remained consistent before and after a donor human milk program was introduced.
  • The model showed that lower odds of feeding MOM at discharge were linked to factors like higher neighborhood poverty, maternal substance use, and younger maternal age, but these odds did not improve after the implementation of the donor human milk program.

Article Abstract

Objective:  This study aimed to develop a predictive model of feeding mother's own milk (MOM) at discharge using social determinants of health (SDOH), maternal and neonatal factors after deliveries at <33 weeks of gestational age (GA), or birth weight <1,500 g.

Study Design:  Secondary analysis of a retrospective cohort in an inner-city hospital before (Epoch-1, 2018-2019) and after (Epoch-2, 2020-2021) implementing a donor human milk (DHM) program.

Results:  Among 986 neonates, 495 were born in Epoch-1 (320 Hispanic White, 142 Non-Hispanic Black, and 33 Other) and 491 in Epoch-2 (327, 137, and 27, respectively). Feeding any MOM was less frequent in infants of non-Hispanic Black mothers than in those of Hispanic mothers ( < 0.05) but did not change with epoch ( = 0.46). Among infants who received any MOM, continued feeding MOM to the time of discharge was less frequent in infants of non-Hispanic Black mothers versus those of Hispanic mothers, 94/237 (40%) versus 339/595 (57%;  < 0.05), respectively. In multivariate analysis including SDOH and maternal variables, the odds of feeding MOM at discharge were lower with SDOH including neighborhoods with higher poverty levels, multiparity, substance use disorder, non-Hispanic Black versus Hispanic and young maternal age and increased with GA but did not change after implementing DHM. The predictive model including SDOH, maternal and early neonatal variables had good discrimination (area under the curve 0.85) and calibration and was internally validated. It showed the odds of feeding MOM at discharge were lower in infants of non-Hispanic Black mothers and with feeding DHM, higher need for respiratory support and later initiation of feeding MOM.

Conclusion:  Feeding MOM at discharge was associated with SDOH, and maternal and neonatal factors but did not change after implementing DHM. Disparity in feeding MOM at discharge was explained by less frequent initiation and shorter duration of feeding MOM but not by later initiation of feeding MOM.

Key Points: · In this cohort study of preterm infants, factors of feeding MOM at discharge included (1) SDOH; (2) postnatal age at initiation of feeding MOM; and (3) maternal and neonatal factors.. · Feeding MOM at the time of discharge was less frequent in infants of non-Hispanic Black mothers versus those of Hispanic mothers.. · Disparity in feeding MOM at discharge was explained by less frequent initiation and shorter duration of MOM feeding but not by later postnatal age at initiation of feeding MOM..
