Comparing Pregnancy Outcomes of Immigrants from Ethiopia and the Former Soviet Union to Israel, to those of Native-Born Israelis.

To compare pregnancy outcomes of immigrants from Former-Soviet-Union (FSUI) and Ethiopia (EI) to those of Jewish-native-born Israelis (JNB), in context of universal health insurance. Birth outcomes of all singletons born in Soroka-University Medical-Center (1998-2011) of EI (n = 1,667) and FSUI (n = 12,920) were compared with those of JNB (n = 63,405). Low birthweight rate was significantly higher among EI (11.0 %) and slightly lower (7.0 %) among FSUI, compared to JNB (7.5 %). Preterm-delivery rates were similar to those of JNB. Both immigrant groups had significantly (p < 0.001) higher rates of perinatal mortality (PM) than JNB (21/1000 in EI, and 11/1000 in FSUI, compared to 9/1000). Using multivariable GEE models both immigrant groups had significantly increased risk for PM; however, EI had twice as much FSUI origin (OR 2.3, 95 % CI 1.6-3.4, and OR 1.3, 95 % CI 1.1-1.6, respectively). Universal health care insurance does not eliminate excess PM in immigrants, nor the gaps between immigrant groups.
