Mississippi’s reputation as a leader in obesity continues. A new report shows in 2007, 45 percent of 10- to 17-year-olds in the southern state were overweight and 22 percent were obese. That’s up from 37 percent and 18 percent, respectively, in 2003.

Meanwhile, Oregon had the fewest obese kids, at 10 percent. It’s also the only state to show big declines in childhood obesity and overweight between 2003 and 2007.
