Placental abruption in immigrant women in Norway: A population‐based study

Abstract

Objective To estimate the incidence of placental abruption in immigrant women compared with non-immigrants by maternal country and region of birth, reason for immigration and length of residence. Design Nationwide population-based study. Setting Data from the Medical Birth Registry of Norway and Statistics Norway (1990-2016). Sample The study sample included 1,558,174 pregnancies, in which immigrant women accounted for 245,887 pregnancies and 1,312,287 pregnancies were to nonimmigrants. Methods Crude and adjusted odds ratios with 95% confidence intervals (CI) for placental abruption in immigrant women compared to non-immigrants were estimated by logistic regression with robust standard error estimations (accounting for within-mother clustering). Adjustment variables included year of birth, maternal age, parity, multiple pregnancies, chronic hypertension and level of education. Main outcome measures Placental abruption Results The incidence of placental abruption decreased during the study period for both immigrants (from 0.68% to 0.44%) and non-immigrants (from 0.80% to 0.34%). Immigrant women from the sub-Saharan African region had an adjusted odds ratio of 1.35 (95% CI: 1.15-1.58) compared to non-immigrants for placental abruption, whereas immigrant women from Ethiopia had an adjusted odds ratio of 2.39 (95% CI 1.67-3.41). We found a small variation in placental abruption incidence by other countries or regions of birth, length of residence and reason for immigration. Conclusion 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.

Trauma in pregnancy: An analysis of the adverse perinatal outcomes and the injury severity score

“…[ 19 ] While the rate of placental abruption was 3.27% in the entire trauma group in our study, this rate was 12.5% in those who gave birth on the same day as the trauma. Considering that placental abruption is seen at a rate of 0.3%–1% in the normal population,[ 20 ] in our clinic its risk increased in patients, who gave birth on the same day, and also weeks after the traumatic incident. In only 1/5 of the cases with placental abruption in our clinic, placental abruption occurred within the first 24 h on the same day as the trauma.…”

Somali women's perceptions and experiences of pain and pain relief during childbirth in Norway: A qualitative study

“…Numerous Norwegian studies have shown that immigrant women, including Somali, have a higher risk of complications in pregnancy and childbirth, as well as poorer perinatal outcomes when compared to non-immigrant women 5,7 . These risks include pre-term birth, placental abruption, emergency cesarean section, stillbirth, and perinatal death [7][8][9][10][11][12] . Furthermore, Norwegian studies show that Somali women receive less epidural analgesia (EDA) during childbirth compared to both ethnic Norwegian and other immigrant women 10,13,14 .…”

Incidence, risk factors, and clinical outcomes of placental abruption in a tertiary hospital in Hong Kong: a retrospective case-control study

“…Its incidence is higher in Canada and the United States and lower in Norway, Spain, Finland, Sweden, the Netherlands, and Denmark 1 . The overall incidence is approximately 3 to 10 per 1000 births 1,2 . Clinical presentation of placental abruption includes painful vaginal bleeding with uterine contraction and hypertonicity and a non-reassuring fetal heart rate pattern 3 .…”
