The USA ranks third in the global prevalence of diabetes, preceded only by India and China. About 7% of the population has diabetes. A third of the total number of people with the condition is believed to be undiagnosed and therefore not receiving treatment to reduce the risk of disabling and life-threatening diabetes complications. The economic costs of diabetes are enormous – estimated at 132 billion USD in 2002. The mission of the US National Diabetes Education Program (NDEP) is to reduce diabetes-related illness and death.
