Working Late In Pregnancy As Dangerous As Smoking, Study Says

A few hours after Yahoo announced to the world that Marissa Mayer would be its new CEO, Mayer announced to the world that she was six months pregnant. She was going to work until her due date, she told Fortune magazine, and would only take a few weeks off with her newborn.

It was a bold declaration. Now, a new study suggests, it might even be a dangerous one. The study, published in the July edition of the Journal of Labour Economics (via Global News Online), shows that working in the last month of pregnancy can have as damaging an effect on a baby's weight as smoking.
