Employment-related physical activity and pregnancy outcome

Concern about possible adverse reproductive effects of employment reflects the increasing participation of pregnant women in the labor force. Although the literature on the effect of employment-related physical activity on pregnancy outcome is substantial, no general consensus has been reached. A growing number of studies, however, suggests that prolonged standing and long working hours may pose a risk to pregnancy. The provision of maternity benefits varies greatly between the United States and European countries. Current modifications of working conditions for both pregnant and non-pregnant women differ even among European countries.
