| Note: Variables not significantly different between groups included the proportion of women who smoked while pregnant, were primiparous; experienced prenatal mood problems, labor and delivery complications, cesarean deliveries; and reported prenatal prenatal job satisfaction. There were no differences between groups on the mean levels of perceived control and preconception overall health and prenatal job stress. The proportion of women on leave vs returned to work at 5 weeks did not vary between women completing the full interview and those completing the mini interview because of time constraints. | ||||
