Hispanic Ethnicity, Nativity and the Risk of Stillbirth

The objective of this study was to examine stillbirth risk by nativity and Hispanic ethnicity. We analyzed births and fetal deaths among women of Hispanic origin within gestational ages of 20–42 weeks from the 2014–2019 Birth and Fetal Death. Foreign-born Hispanic mothers were 8% less likely (HR 0.92, 95% CI 0.90–0.95) to experience stillbirth than their counterparts. Stratified by ethnicity, foreign-born Mexican and Central/South American women had a lower risk of stillbirth (HR 0.85, 95% CI 0.81–0.88 and HR 0.68, 95% CI 0.63–0.75, respectively) while foreign-born Puerto Rican women were more likely to experience stillbirth (HR 1.37, 95% CI 1.24–1.51) than their native-born counterparts. While overall foreign-born Hispanic mothers were less likely to experience stillbirth than native-born Hispanic mothers, this differed depending on ethnicity. Counseling regarding risk of stillbirth among Hispanic women should take into consideration nativity and country of origin as influential factors.
