Diabetes affects 25.8 million people of all ages
8.3 percent of the U.S. population
DIAGNOSED
18.8 million people
UNDIAGNOSED
7.0 million people
- Among U.S. residents ages 65 years and older, 10.9 million, or 26.9 percent, had diabetes in 2010.
- About 215,000 people younger than 20 years had diabetes—type 1 or type 2—in the United States in 2010.
- About 1.9 million people ages 20 years or older were newly diagnosed with diabetes in 2010 in the United States.
- In 2005–2008, based on fasting glucose or hemoglobin A1C (A1C) levels, 35 percent of U.S. adults ages 20 years or older had pre-diabetes—50 percent of adults ages 65 years or older. Applying this percentage to the entire U.S. population in 2010 yields an estimated 79 million American adults ages 20 years or older with pre-diabetes.
- Diabetes is the leading cause of kidney failure, nontraumatic lower-limb amputations, and new cases of blindness among adults in the United States.
- Diabetes is a major cause of heart disease and stroke.
- Diabetes is the seventh leading cause of death in the United States.

[h3]Estimation Methods[/h3]
The estimates in this fact sheet were derived from various data systems of the Centers for Disease Control and Prevention (CDC), the Indian Health Service’s (IHS’s) National Patient Information Reporting System (NPIRS), the U.S. Renal Data System of theNational Institutes of Health (NIH), the U.S. Census Bureau, and published studies. The estimated percentages and the total number of people with diabetes and pre-diabetes were derived from 2005–2008 National Health and Nutrition Examination Survey (NHANES),2007–2009 National Health Interview Survey, 2009 IHS data, and 2010 U.S. resident population estimates. The diabetes and pre-diabetes estimates from NHANES were applied to the 2010 U.S. resident population estimates to derive the estimated number of adults with diabetes or pre-diabetes.
The methods used to generate the estimates for the fact sheet may vary over time and need to be considered before comparing fact sheets. In contrast to National Diabetes Statistics, 2007, which used fasting glucose data to estimate undiagnosed diabetes and pre-diabetes, National Diabetes Statistics, 2011 uses both fasting glucose and A1C levels to derive estimates for undiagnosed diabetes and pre-diabetes. These tests were chosen because they are most frequently used in clinical practice.

[h3]Diagnosed and Undiagnosed Diabetes among People Ages 20 Years or Older, United States, 2010[/h3]
| Group | Number or percentage who have diabetes | | Ages 20 years or older | 25.6 million, or 11.3 percent, of all people in this age group | | Ages 65 years or older | 10.9 million, or 26.9 percent, of all people in this age group | | Men | 13.0 million, or 11.8 percent, of all men ages 20 years or older | | Women | 12.6 million, or 10.8 percent, of all women ages 20 years or older | | Non-Hispanic whites | 15.7 million, or 10.2 percent, of all non-Hispanic whites ages 20 years or older | | Non-Hispanic blacks | 4.9 million, or 18.7 percent, of all non-Hispanic blacks ages 20 years or older |
Sufficient data are not available to estimate the total prevalence of diabetes—diagnosed and undiagnosed—for
other U.S. racial/ethnic minority populations.

[h3]Diagnosed Diabetes[/h3][h4]Diagnosed Diabetes amongPeople Younger than 20 Years ofAge, United States, 2010[/h4]
About 215,000 people younger than 20 years have diabetes—type 1 or type 2. This represents 0.26 percent of all people in this age group. Estimates of undiagnosed diabetes are unavailable for this age group.

[h4]Racial and Ethnic Differences in Diagnosed Diabetes[/h4]
National estimates of diagnosed diabetes for some but not all minority groups are available from national survey data and from the IHS NPIRS, which includes data for about 1.9 million American Indians and Alaska Natives in the United States who receive health care from the IHS. Differences in diabetes prevalence by race/ethnicity are partially attributable to age differences. Adjustment for age makes results from racial/ethnic groups more comparable.
Data from the 2009 IHS NPIRS indicate that 14.2 percent of American Indians and Alaska Natives ages 20 years or older who received care from the IHS had diagnosed diabetes. After adjusting for population age differences, 16.1 percent of the total adult population served by the IHS had diagnosed diabetes, with rates varying by region from 5.5 percent among Alaska Native adults to 33.5 percent among American Indian adults in southern Arizona.
After adjusting for population age differences, 2007–2009 national survey data for people ages 20 years or older indicate that 7.1 percent of non-Hispanic whites, 8.4 percent of Asian Americans, 11.8 percent of Hispanics/ Latinos, and 12.6 percent of non-Hispanic
blacks had diagnosed diabetes. Among Hispanics/Latinos, rates were 7.6 percent for both Cuban Americans and for Central and South Americans, 13.3 percent for Mexican Americans, and 13.8 percent for Puerto Ricans.
Compared with non-Hispanic white adults, the risk of diagnosed diabetes was 18 percent higher among Asian Americans, 66 percent higher among Hispanics/Latinos, and 77 percent higher among non-Hispanic blacks. Among Hispanics/Latinos compared
with non-Hispanic white adults, the risk of diagnosed diabetes was about the same for Cuban Americans and for Central and South Americans, 87 percent higher for Mexican Americans, and 94 percent higher for Puerto Ricans.

[h3]New Cases of Diagnosed Diabetes among People Younger than 20 Years of Age, United States, 2002–2005[/h3]
SEARCH for Diabetes in Youth is a multicenter study funded by the CDC and the NIH to examine diabetes—type 1 and type 2—among children and adolescents in the United States. SEARCH findings for the communities studied include the following:
- During 2002–2005, 15,600 youth were newly diagnosed with type 1 diabetes annually, and 3,600 youth were newly diagnosed with type 2 diabetes annually.
- Among youth ages younger than 10 years, the rate of new cases was 19.7 per 100,000 each year for type 1 diabetes and 0.4 per 100,000 for type 2 diabetes. Among youth ages 10 years or older, the rate of new cases was 18.6 per 100,000 each year fortype 1 diabetes and 8.5 per 100,000 for type 2 diabetes.
- Non-Hispanic white youth had the highest rate of new cases of type 1 diabetes—24.8 per 100,000 per year among those younger than 10 years and 22.6 per 100,000 per year among those ages 10–19 years.
- Type 2 diabetes was extremely rare among youth ages younger than 10 years. While still infrequent, rates were greater among youth ages 10–19 years than in younger children, with higher rates among U.S.minority populations than in non-Hispanicwhites.
- Among non-Hispanic white youth ages 10–19 years, the rate of new cases was higher for type 1 than for type 2 diabetes. For Asian/Pacific Islander Americans and American Indian youth ages 10–19 years, the opposite was true—the rate of new cases was greater for type 2 than for type 1 diabetes. Among non-Hispanic black and Hispanic/Latino youth ages 10–19 years, the rates of new cases of type 1 and type 2 diabetes were similar.
