Pregnancy and delivery among immigrants.

Risk factors during pregnancy and delivery of immigrant women are analysed. Individual birth delivery records of 1 235 immigrant women and of 412 Swedish women are studied. Most of the immigrants--65%--were Scandinavians, while 10% had come from Southern Europe and 4% were non-Europeans. The immigrant groups differed somewhat amongst themselves, and also vis-à-vis the Swedes in some social and demographic respects. Participation in antenatal care was not lower among the immigrants than in the control group, but the former did not attend antenatal exercises to the same extent. The perinatal mortality and prematurity rates were 1.5% and 5%--about the same as among the Swedish women. The rate of premature delivery was found to be related to the duration of residence in Sweden. Women who had lived less than one year in this country more often delivered prematurely than did the more settled immigrant women. Further studies on the emotional reactions of immigrant women during pregnancy and delivery are proposed.
