Incidence and Prevalence

 

In 1995, total new cases diagnosed every day were about 1,700 (1990-1992 average). The total new cases of type II diabetes was about 595,000 new cases per year.

Incidences of diabetes can be seen in the 1995-96 Billing Area Profile of leading cause of outpatient visits. These range from a number one rank on the Rocky Boy reservation to a sixth rank on the Flathead reservation.

The prevalence of diabetes in the U.S. population in 1993 for women was 4.2 million, men 3.6 million, children 19 yrs or younger was 100,000 and adults 65 years or older was 3.2 million.

Among Native Americans, the prevalence of diabetes is higher in women and varies among tribes. Variation ranges from 1.7 % in Alaskan natives to as much as 50% in among the Pima Indians.

These numbers are increasing over time. In the global population, it was estimated in 1900 that 25 million people had diabetes. In 2015, it is estimated that 250 million people will have diabetes. In a Pima Indian study sponsored by the National Institute of Health, diabetes rates increased from 3.2% in the 1950s to 50% in the 1980s in people age 35 and older.
