Children who are overweight face more than future health problems. They appear to have broken bones and joint problems more often during childhood than kids of normal weight, research suggests.

"A lot of people think that if you're an overweight kid ... that later on in life you're going to run into having heart disease or Type 2 diabetes," said Dr. Susan Yanovski, director of the obesity and eating disorders program at the National Institute of Diabetes and Digestive and Kidney Diseases.

"But kids and adults who are overweight are already having problems with their mobility, fractures, and joint pain."
