America’s Obesity Epidemic

It’s no secret that America has a weight problem. Still, researchers from Brigham Young University are revealing just how widespread expanding waists have become.

Scientists tracked nearly 1,400 American adults for a decade. More than half saw their body weight increase by at least five percent, while over a third gained 10 percent or more body weight. Close to a fifth gained at least 20 percent more body weight.

“The U.S. obesity epidemic is not slowing down,” says study lead author Larry Tucker, a BYU professor of exercise science, in a university release. “Without question, 10-year weight gain is a serious problem within the U.S. adult population.”

Participants were chosen for this project randomly as part of the National Health and Nutrition Examination Survey (NHANES), an annual nationally representative survey sponsored by the Centers for Disease Control and Prevention.
