Possible influence of expatriation on perinatal outcome

In order to test the hypothesis of possible influence of environmental stress on the length of gestation the data on deliveries in the Maternity Unit, Zagreb University School of Medicine in three six months periods ; May-October 1991 (active war in Croatia), May-October 1990 (pre-war period), and the same period in 1992 are analysed. Deliveries of 7845 women from free areas of Croatia (non-displaced population) and deliveries from 712 women from occupied areas of Croatia, as well of 593 Croatian refugees from Bosnia and Herzegovina and Serbia (expatriated population) were compared. The duration of pregnancy, fetal weight, immediate neonatal condition, mode of delivery and perinatal outcome in non-displaced and expatriated population were compared using chi-square test in statistical analysis. During 1992 and 1991, there was a slight increase in total number of deliveries in comparison to 1990. The number of deliveries by displaced women more than doubled. The incidence of major pregnancy complications was almost the same for both groups in all three time periods. The two populations were comparable regarding their age, parity and previous obstetric history. Slight increase in preterm delivery rate (7.7% in l990, 8.7% in 1991 and 9.4% in 1992), and a subsequent slight decrease in birth weight was found in all women. There was no significant change in the proportion of growth-retarded newborns. Expatriated women both in 1990 and in 1991 delivered twice as often prematurely in comparison to non-displaced women (17.5% and l4.3% deliveries), respectively. Birth weight of their infants was significantly more often under 2500 grams. Slight increase in overall perinatal mortality was observed. Perinatal mortality in the experiated population was significantly higher than in the non-displaced population. Increase in perinatal mortality could be attributed exclusively to increase in prematurity rate. Our results support the concept of possible influence of stress, fear, exile and inadequate antenatal surveillance on the length of gestation.
