Effects of Long Working Hours & Long Standing on Fetal Growth


A Dutch longitudinal comparison of pregnant women who often stood for long periods of time gave birth to babies with slightly but significantly smaller head circumferences (P<0.05)  compared to babies of mothers who were not on their feet for long periods. Women who worked 25 hours a week or more during pregnancy also gave birth to babies with smaller head circumferences and birth weights (P<0.05) than those who workerd shorter hours. However, there were no significant associations for physically demanding work. More research is needed to determine if these findings affect the development of the child.

PositiveTip: Pregnant ladies: be cautious of standing for long periods or working long hours if possible.
