Background: Racial disparities in breastmilk provision and neonatal morbidities of extreme prematurity have been documented in previous studies but are not as well-documented in Asian and Pacific Islander (API) infants. The objectives of this study were to evaluate a predominantly API neonatal intensive care unit (NICU) population for racial disparities in (1) the receipt of breastmilk within 24 h of admission and at discharge and (2) neonatal morbidities among infants ≤ 28 weeks gestational age.
Methods: A retrospective chart review of 2528 infants from 2018 to 2020 born at the largest level 3 NICU in Honolulu, Hawai'i, was conducted. Multivariable logistic regression analysis was performed on NICU outcomes to calculate adjusted odds ratios (aOR) and confidence intervals (CI).
Results: Native Hawaiian (NH) (aOR 0.73 [0.54, 0.98]), Pacific Islander (PI) (aOR 0.57 [0.41, 0.79]), and Filipino infants (aOR 0.66 [0.49, 0.89]) were less likely to receive breastmilk at discharge compared to Asian infants. PI infants were also more likely to experience necrotizing enterocolitis (aOR 7.89 [1.07, 58.10]) and intraventricular hemorrhage (aOR 3.86 [1.15, 13.02]) compared to Asian infants.
Conclusion: In a predominantly API population, disparities in breastmilk receipt and neonatal morbidities exist among NH, PI, and Filipino infants in the NICU. Our findings call for better understanding of the underlying inequities to guide directed efforts, including standardization of care through staff trainings on implicit biases and trauma-informed care, as well as provision of culturally sensitive education and lactation support for these patients.
