1135: Increasing rate of no prenatal care in pregnancies complicated by Hepatitis C in the US

Abstract

anomalous, cephalic, singleton pregnancies, exposed to labor, and delivered at 37,0 to 41,6 weeks were included. Women with hypertensive disorders, pregestational/gestational diabetes, or whose race/ ethnicity was unknown or classified as "other" were excluded. Maternal race/ethnicity as recorded on the birth certificate was used to categorize women and infants as follows: non-Hispanic White (White), non-Hispanic Black (Black), Hispanic, or non-Hispanic Asian (Asian). Multivariable Poisson regression models with robust error variance were used to evaluate the association between maternal race/ethnicity and composite adverse neonatal outcome (CANO), infant mortality, and composite adverse maternal outcome (CAMO). RESULTS: Of 9,205,873 women who met inclusion criteria, 55.5% were White, 13.7% Black, 24.3% Hispanic, and 6.5% Asian. Compared with neonates of White women, the risk of CANO was higher for neonates of Black women, and lower for neonates of Hispanic and Asian women. Infant mortality was also highest for infants born to Black women, and lower for infants born to Hispanic and Asian women (Table 1). The risk of CAMO was similar for Black women, lower for Hispanic women, and higher for Asian women compared with White women. A sensitivity analysis of CAMO without maternal transfusion noted a higher risk for all racial/ethnic groups when compared with White women (Table 2). CONCLUSION: Among low-risk pregnancies at 37 to 41 weeks, racial/ ethnic disparities in adverse outcomes persist. While infants of Black women appear to be at highest risk for morbidity and mortality, Asian mothers have the highest risk of maternal morbidity.
