[Employment during pregnancy and neonatal morbidity].

Neonatal morbidity was higher among the babies of 521 women who were gainfully employed during pregnancy compared to those of 475 non working women of the same area (Aarau, Switzerland). The difference was lower (6%) in the part time employed than in those working full time (11%.) It was almost entirely due to the higher number of primiparae and of smokers among those women who were working during pregnancy.
