Incidence of Diagnosed Diabetes

Incidence Among Adults

  • In 2015, an estimated 1.5 million new cases of diabetes (6.7 per 1,000 persons) were diagnosed among U.S. adults aged 18 years or older (Table 2) (Methods).
  • More than half of these new cases were among adults aged 45 to 64 years, and the numbers were about equal for men and women (Table 2).
  • Non-Hispanic blacks (9.0 per 1,000 persons) and people of Hispanic origin (8.4 per 1,000 persons) had a higher age-adjusted incidence compared to non-Hispanic whites (5.7 per 1,000 persons) during 2013–2015 (see Table 2a in the Appendix for more details).
  • Age-adjusted incidence was about 2 times higher for people with less than a high school education (10.4 per 1,000 persons) compared to those with more than a high school education (5.3 per 1,000 persons) during 2013–2015 (see Table 2a in the Appendix for more details).

Figure 3 shows model-based county-level estimates of the age-adjusted incidence of diagnosed diabetes among U.S. adults aged 20 years or older in 2013 (Methods). Specifically, this figure shows that:

  • The median age-adjusted county-level incidence of diagnosed diabetes was 8.2 per 1,000 persons, with a range of 3.1 to 21.9 per 1,000 persons.
  • Similar to the geographic pattern of the prevalence of diagnosed diabetes, counties in the southern and Appalachian regions of the United States tended to have the highest incidence.

Incidence Among Children and Adolescents

Data from the SEARCH for Diabetes in Youth Study1 indicated that:

  • During 2011–2012, the estimated annual number of newly diagnosed cases in the United States included:
    • 17,900 children and adolescents younger than age 20 years with type 1 diabetes.
    • 5,300 children and adolescents age 10 to 19 years with type 2 diabetes.
  • Among children and adolescents younger than age 20 years, non-Hispanic whites had the highest rate of new cases of type 1 diabetes compared to members of other U.S. racial and ethnic groups (Figure 4).
  • Among children and adolescents aged 10 to 19 years, U.S. minority populations had higher rates of new cases of type 2 diabetes compared to
    non-Hispanic whites (Figure 4).
