Prevalence and Incidence of Diabetes


advertisement

About prevalence and incidence statistics: The term 'prevalence' of Diabetes usually refers to the estimated population of people who are managing Diabetes at any given time. The term 'incidence' of Diabetes refers to the annual diagnosis rate, or the number of new cases of Diabetes diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.

Prevalance of Diabetes: 16 million Americans with 10.3 million diagnosed and 8.1 million women (NWHIC); 65 per 1000 - NHIS95; 8 million - perhaps 16 million if include not-yet-diagnosed.
Prevalance Rate: approx 1 in 17 or 5.88% or 16 million people in USA [about data]
Incidence (annual) of Diabetes: approximately 798,000 new cases diagnosed annually in USA (CDC-OC)
Incidence Rate: approx 1 in 340 or 0.29% or 798,000 people in USA [about data]
Undiagnosed prevalence of Diabetes: 5.7 million Americans (based on NWHIC)
Undiagnosed prevalence rate: approx 1 in 47 or 2.10% or 5.7 million people in USA [about data]
  Undiagnosed prevalence statistics about Diabetes: The following statistics relate to undiagnosed cases of Diabetes:
  • Estimated 5.2 million people have undiagnosed diabetes in the US 2002 (National Diabetes Statistics fact sheet, NIDDK, 2003)
  • 730,000 African Americans are unaware they have diabetes in America (CBCF Health Organisation, 2004)
  • Half of the estimated 1 million people with diabetes were unaware of that they had diabetes in Australia 2001 (Australia’s Health 2004, AIHW)

Worldwide prevalence of Diabetes:135 million cases worldwide 1995
Prevalance of Diabetes: According to recent estimates, the prevalence of diabetes in the United States is predicted to be 8.9 percent of the population by 2025. 1 ... About 16 million Americans have diabetes, but only about 10 million have been diagnosed.2
Incidence of Diabetes: Approximately 798,000 new cases of diabetes are diagnosed annually in the United States.2 ... New cases diagnosed per year: 798,000. 3

Prevelance of Diabetes discussion: The number of persons diagnosed with diabetes has increased sixfold, from 1.6 million in 1958 to 10 million in 1997. Diabetes is the nation's seventh leading killer and contributed to about 187,800 deaths in 1995. 2

Total: 15.7 million people--5.9 percent of the population--have diabetes.

    Diagnosed: 10.3 million people
    Undiagnosed: 5.4 million people

Prevalence of diabetes by age Age 65 years or older: 6.3 million. 18.4 percent of all people in this age group have diabetes.

Age 20 years or older: 15.6 million. 8.2 percent of all people in this age group have diabetes.

Under age 20: 123,000. 0.16 percent of all people in this age group have diabetes.3

"Other specific types" of diabetes result from specific genetic syndromes, surgery, drugs, malnutrition, infections, and other illnesses. Such types of diabetes may account for 1 to 2 percent of all diagnosed cases of diabetes. 3

Between the 1995 and 1997 fact sheets, the number of persons with diagnosed diabetes increased from 8 million to 10.3 million, but the number of persons with undiagnosed diabetes decreased.3
