- Background: Many births in industrialised countries are to immigrant parents, or to one immigrant and one domestically born parent. Their newborn outcomes have not been well studied. Methods: We conducted a study of 1690423 singleton infants born in Sweden between 1987 and 2008, including those of immigrants from East Asia, South Asia, Sub-Saharan Africa, and East Africa. Preterm delivery and small for gestational age (SGA) were assessed among infants of (i) immigrant parents from the same world region, (ii) an immigrant mother and a Swedish-born father, and (iii) a Swedish-born mother and an immigrant father; each compared to (iv) two Swedish-born parents. Log binomial regression analysis generated adjusted risk ratios (ARRs) and 95% confidence intervals (CIs) for preterm delivery and SGA.Results: Compared with infants of two Swedish-born parents, infants born to immigrant mothers from East Asia, South Asia, and Sub-Saharan African were at higher risk of preterm delivery (ARR ranging from 1.2 to 1.9), irrespective of whether the father was from the same world region or Swedish-born, with the only exception of East African women, who had lower risk. Infants born to two foreign-born parents had the highest risks of SGA, particularly South Asians (ARR 4.69; 95% CI 4.29, 5.12). Mixed couples exhibited intermediate risks of SGA. Conclusions: Adverse birth outcomes differ according to a couple's ethnic composition. Having a Swedish-born partner is associated with lower risk of SGA among immigrant mothers and fathers, and with lower risk of preterm delivery among immigrant fathers but not mothers.

- BACKGROUND:Maternal mortality and morbidity vary substantially worldwide. It is unknown if these geographic differences translate into disparities in severe maternal morbidity among immigrants from various world regions. We assessed disparities in severe maternal morbidity between immigrant women from various world regions giving birth in three high-immigration countries.METHODS:We used population-based delivery data from Victoria; Australia and Ontario, Canada and national data from Denmark, in the most recent 10-year period ending in 2010 available to each participating centre. Each centre provided aggregate data according to standardized definitions of the outcome, maternal regions of birth and covariates for pooled analyses. We used random effects and stratified logistic regression to obtain odds ratios (ORs) with 95% confidence intervals (95% CIs), adjusted for maternal age, parity and comparability scores.RESULTS:We retrieved 2,322,907 deliveries in all three receiving countries, of which 479,986 (21%) were to immigrant women. Compared with non-immigrants, only Sub-Saharan African women were consistently at higher risk of severe maternal morbidity in all three receiving countries (pooled adjusted OR: 1.67; 95% CI: 1.43, 1.95). In contrast, both Western and Eastern European immigrants had lower odds (OR: 0.82; 95% CI: 0.70, 0.96 and OR: 0.64; 95% CI: 0.49, 0.83, respectively). The most common diagnosis was severe pre-eclampsia followed by uterine rupture, which was more common among Sub-Saharan Africans in all three settings.CONCLUSIONS:Immigrant women from Sub-Saharan Africa have higher rates of severe maternal morbidity. Other immigrant groups had similar or lower rates than the majority locally born populations.
