Diabetes will place an immense burden on Arizona’s various health care delivery systems in the next decade. If the diabetes prevalence rate remains steady, by the year 2020 it is estimated there will be approximately 485,000 persons with diabetes in Arizona. However, measures of diabetes prevalence, mortality, hospitalization and major risk factors indicate that current rates are worsening. The increase is seen among all ethnic and racial groups. This report contains county-specific information about the prevalence, mortality, and hospitalization of persons with diabetes. It also shows the distribution of diabetes educators, who are effective in encouraging optimal care of persons with diabetes.
