Placental abruption is a serious complication in pregnancy. While its incidence varies across countries, the information of how abruption varies in immigrant populations is limited. The aims of this study were to estimate the incidence of placental abruption in immigrant women compared to non-immigrants by maternal country and region of birth, reason for immigration and length of residence. We conducted a nationwide population-based study using data from the Medical Birth Registry of Norway and Statistics Norway (1990-2016). The study sample included 1,558,174 pregnancies, in which immigrant women accounted for 245,887 pregnancies and 1,312,287 pregnancies were to non-immigrants. The incidence of placental abruption decreased during the study period for both immigrants and non-immigrants. Immigrant women from sub-Saharan Africa, especially Ethiopia, have increased odds for placental abruption when giving birth in Norway. Reason for immigration and length of residence had little impact on the incidence of placental abruption.
