Diabetes Report Card 2012: National and State Profile of Diabetes and Its Complications
Incidence of Diagnosed Diabetes
Figure 1 shows diabetes incidence in the United States, which is the number of new cases diagnosed each year. The number of new cases of diabetes changed little from 1980 through 1990, but began increasing in 1992. From 1990 through 2010, the annual number of new cases of diagnosed diabetes almost tripled. The rise in the incidence of type 2 diabetes cases is associated with increases in obesity, decreases in leisure-time physical activity, and the aging of the U.S. population.7
