ATLANTA - There's another sign that childhood obesity may be on the decline nationwide.
A government study finds that obesity among children ages 2 to 5 has dropped to 8 percent -- from 14 percent a decade ago. But the decline was only seen in pre-schoolers, not in older children.
And some experts point out that even the improvement in toddlers wasn't a steady decline. They say it's hard to know whether the weight figures for pre-schoolers are permanently curving down.
The report appears online in the Journal of the American Medical Association.
Health officials have been hoping for more substantial evidence that they've turned a corner in the fight against childhood obesity.
A third of U.S. children and teens, and more than two-thirds of adults, are obese or overweight. It's seen as one of the nation's leading public health problems. Health officials call it a longstanding epidemic.
Pre-schoolers who are overweight or obese are five times more likely than other children to be heavy as adults. That means a greater risk of high cholesterol, high blood sugar, asthma and even mental health problems.
