Activity and work during pregnancy and the postpartum period: a cross-cultural study of 202 societies.

Cross-cultural information on 202 traditional societies was perused for data on customs surrounding the expected work load of pregnant and postpartum women. The most common single pattern of work activity during pregnancy was that of continuing full duties until the onset of labor. A bare majority of societies did encourage a lightening of work at some time during pregnancy. Postnatally, most societies did restrict maternal work activity; however, few suspended usual work duties for prolonged periods of time. About one half of societies expected a return to full duties within 2 weeks. Results suggest that the current American trend toward increased participation of women of childbearing age in the work force may be in keeping with the work loads of women in traditional societies.
