Indications for admission in a high-risk pregnancy unit in Greece: Comparison between native and migrant women. A single-center experience

Introduction: Migrant pregnant women may require antenatal hospitalization due to complications of pregnancy. The aim of this study was to investigate the indications for admission, the baseline and the obstetric characteristics of migrant women hospitalized in a high-risk pregnancy unit (HRPU) and compare them with the native-Greek individuals. Materials and Methods: A retrospective cohort study was conducted during the period 2005-2019. All pregnant women at ≥ 24 gestational weeks admitted in a University hospital HRPU were eligible for the study. Epidemiological characteristics, along with the indications for admission were studied and comparisons of several parameters between native-Greek and migrant pregnant women were conducted. Results: Overall, 3,823 women were included in the study, of which 838 (21.9%) were migrant women. The main indication for hospital admission was threatened preterm labor (38.0%). When we compared the two groups in terms of indications for admission, we found that maternal indications were more common in migrants than Greek pregnant women (32.8% vs 26.8%; p=0.001; OR:1.332; 95% CI:1.129-1.571). Compared to native women, migrants were younger (28.7±6.1 vs 30.9±6.4 years, p
