Maternal language disparities in neonatal intensive care unit outcomes

Abstract

Objective

To examine associations of maternal primary language with neonatal intensive care unit (NICU) outcomes (mother’s milk at discharge, necrotizing enterocolitis [NEC], late-onset sepsis, weight gain)

Design

We performed a retrospective cohort study of mother-infant dyads (<34 weeks’ gestation) in 9 NICUs (1/2016-12/2019), examining associations of maternal language (English [ref], Spanish, Other) with NICU outcomes, adjusting for birth weight for gestational age z-score, race/ethnicity, maternal age, and clustering by hospital.

Results

Among 1402 mothers, 85% spoke English, 7% spoke Spanish, and 7% spoke another language. Compared to English, infants with Spanish-speaking mothers had slower growth (−0.34 z-score units [−0.58, −0.10]). Infants with other non-English-speaking mothers had increased mother’s milk at discharge (aOR 1.48 [1.18, 1.85]), NEC (aOR 1.43 [1.05, 1.95]), late-onset sepsis (aOR 2.84) [1.67, 4.83] and slower growth (−0.17 z-score units [−0.29, −0.05]).

Conclusions

After adjustments, preterm infants with non-English-speaking mothers had worse outcomes than infants with English-speaking mothers.
