It's hateful that they did this study and it's hateful that I'm posting a link to a news story about it.

Children born to women who have achieved drastic weight loss through stomach surgery are healthier than children born to severely obese moms, a new study shows. The findings suggest that obesity creates an unhealthy environment for a fetus that has ramifications later on, scientists report in the November Journal of Clinical Endocrinology & Metabolism.

“This is very important work,” says Dana Dabelea, a physician and epidemiologist at the University of Colorado—Denver and the Colorado School of Public Health in Aurora. “This is the first proof that exposure to obesity in utero is associated with long-term effects,” she says.

Any effort to assess the health consequences of obesity = hate. Please make a note of it.
