Obstetric Outcomes of First- and Second-Generation Pakistani Immigrants: A Comparison Study at a Low-Risk Maternity Ward in Norway

This population-based study compares obstetric outcomes of first- and second-generation Pakistani immigrants and ethnic Norwegians who gave birth at the low-risk maternity ward in Baerum Hospital in Norway from 2006 to 2013. We hypothesized that second-generation Pakistani immigrants are more similar to the ethnic Norwegians because of increased acculturation. Outcome measures were labor onset, epidural analgesia, labor dystocia, episiotomy, vaginal/operative delivery, postpartum hemorrhage, preterm birth, birth weight, transfer to a neonatal intensive care unit, and neonatal jaundice. Compared to first-generation Pakistani immigrants, the second-generation reported more health issues before pregnancy, and they had a higher proportion of preterm births compared to Norwegians. Newborns of first-generation immigrants were more often transferred to a neonatal intensive care compared to Norwegian newborns. Few intergenerational differences in the obstetric outcomes were found between the two generations. A high prevalence of consanguinity in second-generation immigrants suggests the maintenance of a traditional Pakistani marriage pattern.
