* Weight. Being overweight is a primary risk factor for type 2 diabetes in children.
* Inactivity. The less active your child is, the greater his or her risk of type 2 diabetes.
* Family history. The risk of type 2 diabetes significantly increases if a parent or sibling has type 2 diabetes — but it's difficult to tell if this is related to lifestyle, genetics or both.
* Race. Although it's unclear why, children of certain races — especially blacks, Hispanics, Native Americans, Asian-Americans, and Pacific Islanders — are more likely to develop type 2 diabetes.
* Sex. Type 2 diabetes is more common in girls than in boys during childhood.
