Perceived discrimination and risk of preterm birth among Turkish immigrant women in Germany

Health disparities, including adverse birth outcomes, exist between Turkish immigrants and the autochthonous population in Germany. The state of research on the risk of preterm birth (PTB, defined as <37 weeks of gestation), the leading cause of infant mortality and morbidity, among Turkish immigrant women is mixed. Perceived discrimination is discussed in the context of health disparities related to migration. We examined whether PTB risk is also increased in Turkish immigrant women in Germany and whether perceived discrimination due to origin contributes to this risk.

We selected a sample from the German Socio-Economic Panel (SOEP) study of German autochthonous and Turkish immigrant women who recently gave birth (between 2002 and 2016) (N = 2,525, incl. n = 217 Turkish immigrant women of which n = 111 completed an item on perceived discrimination). The included variables of central interest were immigrant status, perceived discrimination, gestational age, and socioeconomic situation.

Logistic regression models indicated that PTB risk was significantly higher for Turkish immigrant women than autochthonous women (OR: 2.75, 95% CI [1.79-4.16]), even when adjusting for socioeconomic status. Within the subsample of Turkish immigrant women, perceived discrimination was related to a significantly higher PTB risk (OR: 4.91, 95% CI [1.76-15.06]).

Our study provides evidence for a higher PTB risk in Turkish immigrant women compared to autochthonous women in Germany. Perceived discrimination may contribute to this higher risk. The findings represent an important first step towards developing targeted interventions to improve pregnancy and birth outcomes in minority groups.
