Physicians group labels obesity a disease

(CNN) -- One word could have a big impact on the way doctors treat obesity in the United States.

The American Medical Association has adopted a new policy that officially labels obesity as a disease "requiring a range of medical interventions to advance obesity treatment and prevention," according to an AMA statement.

The physicians' group voted to approve the obesity policy, among others, on Tuesday during its annual meeting in Chicago.

The U.S. obesity rate increased almost 50% between 1997 and 2012, according to the Centers for Disease Control and Prevention. Today, nearly 30% of American adults are considered obese, and the problem is almost as prevalent in kids. Childhood obesity has more than doubled in the past 30 years, the CDC says.
