Stress At Work May Impact Fetus During First Trimester

WASHINGTON, DC (WUSA) -- The most recent data from the Census Bureau indicates that women are more likely to work while pregnant. They are also working later into the pregnancy.

This doesn't bode well for the unborn child according to a recent study by the American Journal of Public Health.

The research shows that working 32 hours or more during the first trimester of pregnancy may raise the chances of a low birth weight for baby.

"For me the story generally holds true. When I had him about 22 months ago, he was seven pounds and 14 ounces and I was not working. Then I was working almost 50 hours a week when I was pregnant with [my daughter.] She was born only six pounds and six ounces. So for me, the research is true," says Kathy Atanasov from Williamsburg, Va.

Researchers surveyed 8,266 women in the Netherlands about their work environment. Turns out, high mental stress and long hours make for the risky combo.

Researchers concluded that the most likely reason for the low birth weight may be because stress releases hormones that hinder the critical growth of the fetus during the first trimester.

The results may indicate the first trimester of pregnancy is just as critical as the last trimester.
