Parenting and obesity: Are foster homes better choice for fattest kids?

CHICAGO -- Should parents of extremely obese children lose custody for not controlling their kids' weight? A provocative commentary in one of the nation's most distinguished medical journals argues yes, and its authors are joining a quiet chorus of advocates who say the government should be allowed to intervene in extreme cases.

It has happened a few times in the U.S., and the opinion piece in today's Journal of the American Medical Association says putting children temporarily in foster care is in some cases more ethical than obesity surgery.

Dr. David Ludwig, an obesity specialist at Harvard-affiliated Children's Hospital Boston, said the point isn't to blame parents, but rather to get children the help they need.

State intervention "ideally will support not just the child but the whole family, with the goal of reuniting child and family as soon as possible. That may require instruction on parenting," said Ludwig, who wrote the article with Lindsey Murtagh, a lawyer and a researcher at Harvard's School of Public Health.

But University of Pennsylvania bioethicist Art Caplan said he worries that the debate risks putting too much blame on parents. Obese children are victims of advertising, marketing, peer pressure and bullying -- things a parent can't control, he said.

Jerri Gray, a Greenville, S.C., single mother who lost custody of her 555-pound 14-year-old son two years ago, said authorities don't understand the challenges families may face in trying to control kids' weight. "I was always working two jobs so we wouldn't end up living in ghettos," Gray said. She said she often didn't have time to cook, so she would buy her son fast food. She said she asked doctors for help for her son's big appetite but was accused of neglect.

Her sister has custody of the boy, now 16. The sister has the money to help him with a diet and exercise, and he has lost more than 200 pounds. "Even though good has come out of this as far as him losing weight, he told me just last week, 'Mommy, I want to be back with you so bad.' They've done damage by pulling us apart," Gray said.
