Slide 3:
Prevalence of Diabetes and Impaired Fasting Glucose,
US, 1988-1994
|
|
The prevalence of
diabetes, impaired fasting glucose, and impaired glucose tolerance in United
States adults was assessed by Harris et al from data in the Third National
Health and Nutrition Examination Survey, 1988-1994 (NHANES III). The
population consisted of 18,825 adults 20 years of age or older who were
interviewed to ascertain a medical history of diagnosed diabetes as well as
subsets of 6,587 adults 20 years of age and 2,844 adults 40 to 74 years of age
without a history of diabetes who underwent fasting plasma glucose testing or
oral glucose tolerance testing, respectively.
|
|
Prevalence of
diagnosed diabetes was estimated to be 5.1% for United States adults 20 years (10.2
million).
|
|
Using the 1997
American Diabetes Association diagnostic criterion
(FPG 126 mg/dL), the prevalence of undiagnosed diabetes was 2.7%
(5.4 million).
|
|
The prevalence of
impaired fasting glucose (110 mg/dL to < 126 mg/dL) was 6.9% (13.4
million).
|
|
As shown on this
slide, the prevalence of patients with diabetes (diagnosed and undiagnosed)
and impaired fasting glucose increases progressively with age until they
comprise almost one third of the population 60
years of age and older.
