Total Prevalence of Diabetes in the United States, All
Total: 20.8 million people—7 percent of the
Diagnosed: 14.6 million people
Undiagnosed: 6.2 million people
Prevalence of Diagnosed Diabetes in People Aged 20 Years
or Younger, United States, 2005
About 176,500 people aged 20 years or younger have
diabetes. This group represents 0.22 percent of all people in this age
About one in every 400 to 600 children and adolescents has
type 1 diabetes.
Although type 2
diabetes can occur among youth, the nationally
representative data that would be needed to monitor diabetes trends in
youth by type are not available. Clinically based reports and regional
studies suggest that type 2 diabetes, although still rare, is being
diagnosed more frequently in children and adolescents, particularly in
American Indians, African Americans, and Hispanic/Latino Americans.
Deaths Among People with Diabetes, United States, 2002
- Diabetes was the sixth leading cause of death listed on
certificates in 2002. This ranking is based on the 73,249 death
certificates in which diabetes was listed as the underlying cause of
death. According to death certificate reports, diabetes contributed to
a total of 224,092 deaths.
- Diabetes is likely to be underreported as a cause of death.
have found that only about 35 to 40 percent of decedents with diabetes
have diabetes listed anywhere on the death certificate and only about
10 to15 percent had it listed as the underlying cause of death.
- Overall, the risk for death among people with diabetes is
about twice that of people without diabetes of similar age.
Complications of Diabetes in the United States
Heart disease and stroke
- Heart disease and stroke account for about 65 percent of
deaths in people with diabetes.
- Adults with diabetes have heart disease death rates about 2
to 4 times higher than adults without diabetes.
- The risk for stroke is 2 to 4 times higher among people
High blood pressure
- About 73 percent of adults with diabetes have blood
greater than or equal to 130/80 mm Hg or use prescription medications
- Diabetes is the leading cause of new cases of blindness
among adults aged 20 to 74 years.
- Diabetic retinopathy causes 12,000 to 24,000 new cases of
blindness each year.
- Diabetes is the leading cause of kidney failure, accounting
for 44 percent of new cases in 2002.
- In 2002 in the United States and Puerto Rico, 44,400 people
with diabetes began treatment for end-stage kidney disease.
- In 2002 in the United States and Puerto Rico,153,730 people
end-stage kidney disease due to diabetes were living on chronic
dialysis or with a kidney transplant.
Nervous system disease
- About 60 to 70 percent of people with diabetes have mild to
forms of nervous system damage. The results of such damage include
impaired sensation or pain in the feet or hands, slowed digestion of
food in the stomach, carpal tunnel syndrome, and other nerve problems.
- Almost 30 percent of people with diabetes aged 40 years or
have impaired sensation in the feet (i.e., at least one area that lacks
- Severe forms of diabetic nerve disease are a major
contributing cause of lower-extremity amputations.
- More than 60 percent of nontraumatic lower-limb amputations
occur among people with diabetes.
- In 2002, about 82,000 nontraumatic lower-limb amputations
were performed in people with diabetes.
- Periodontal (gum) disease is more common in people with
Among young adults, those with diabetes have about twice the risk of
those without diabetes.
- Almost one-third of people with diabetes have severe
diseases with loss of attachment of the gums to the teeth measuring 5
millimeters or more.
Complications of pregnancy
- Poorly controlled diabetes before conception and during the
trimester of pregnancy can cause major birth defects in 5 to 10 percent
of pregnancies and spontaneous abortions in 15 to 20 percent of
- Poorly controlled diabetes during the second and third
of pregnancy can result in excessively large babies, posing a risk to
both mother and child.
- Uncontrolled diabetes often leads to biochemical imbalances
can cause acute life-threatening events, such as diabetic ketoacidosis
and hyperosmolar (nonketotic) coma.
- People with diabetes are more susceptible to many other
and, once they acquire these illnesses, often have worse prognoses. For
example, they are more likely to die with pneumonia or influenza than
people who do not have diabetes.
