Abstract
OBJECTIVE: This study aimed to compare the perinatal outcomes among U.S.-born and foreign-born Hispanics and Caucasians and ascertain if length of time in the US was associated with the rate of adverse outcomes. STUDY DESIGN: Retrospective cohort analysis of gravidae enrolled in our institutional perinatal database. Women delivering a non-anomalous, singleton, at 24 weeks or more and self-identified as Caucasian or Hispanic were included. Women were stratified by country of birth and ethnicity into U.S.-born Caucasian, U.S.-born Hispanic, and U.S. foreign-born Hispanic. Composite maternal (CMM) and neonatal (CNM) morbidity was assessed. RESULTS: Of 20,422 women, 21% were Caucasian, 15% were U.S.-born Hispanics, and 64% were U.S. foreign-born Hispanics. Compared to Caucasians, U.S.-born and foreign-born Hispanic were older, more likely to be a grand multiparous, obese and less likely to be married. Compared to Caucasians, foreign-born Hispanics had a 1.42-fold increased risk of CMM (95% CI 1.26-1.30). Paradoxically, the rate of CNM was 40% lower among neonates born to foreign-born Hispanics (95% CI 0.51-0.74). A significant direct relationship was noted between time in the USA and CMM but not CNM among foreign-born Hispanics. CONCLUSION: Despite less favorable baseline characteristics, U.S. foreign-born Hispanics have 40% less CNM compared to both Caucasians and U.S.-born Hispanics. Thieme. All rights reserved.
