File under Duh!!!
There was an interesting article from Reuters about how kids and (adults as found in a previous study) are more likely to be obese if they live in the suburbs. I think a lot of it also happens to be that if there is nothing to do close by, you'll just sit home and watch TV. Maybe the Nintendo's Wii will save our waistlines. From the report.
"The findings echo those of a 2003 study by the same researchers that
focused on U.S. adults. The researchers believe the same factors may be
driving the link between suburban living and teenagers' weight -- the
major one being reliance on cars."
