Recent Trends in NICU Admission Among Women With Gestational Diabetes by Race and Ethnicity [A172

Abstract

INTRODUCTION: To determine if NICU admission rates are increasing among neonates born to women with gestational diabetes and if there are disparities by race and ethnicity. METHODS: This was a retrospective cohort study of deliveries between 2014 and 2018 in the United States. Inclusion criteria were non-anomalous, singleton deliveries with gestational age ≥20 weeks and gestational diabetes. Analyses were stratified by maternal race/ethnicity, including the following categories: non-Hispanic (NH) White, NH Black, NH American Indian or Alaska Native (AI/AN), NH Asian or Native Hawaiian and Pacific Islander (NHOPI), NH multiracial and Hispanic. The confounders assessed included age, parity, cigarette use, educational attainment, gestational age at delivery, birth weight, and insurance type. We used multivariable logistic regression and calculated predicted probabilities (PP) to estimate the adjusted proportion of deliveries resulting in NICU admission. All analyses were conducted using STATA 17. RESULTS: There were 1,104,082 deliveries included in this analysis. The predicted probability of NICU admission was higher in 2018 than in 2014 for NH White, NH Black, and Hispanic women, but the results were not statistically significant. The predicted probability was lower in 2018 than in 2014 for NH AI/AN, NH Asian/NHOPI, and NH multiracial women, but the results were not statistically significant. The predicted probability of NICU admission was highest among women who were NH Black at 12.42%, and lowest among women who were NH AI/AN at 9.7%. CONCLUSION: NICU admissions may be increasing among some neonates of pregnant women with gestational diabetes, and there are disparities in admission rates when accounting for race and ethnicity.
