USA Diabetes Statistics
Total: 20.8 million people have diabetes.
Diagnosed: 14.6 million people
Undiagnosed: 6.2 million people
Prevalence of Diabetes Among People Under 20 Years of Age
About 176,500 people less than 20 years of age have diabetes. This represents 0.22% of all people in this age group.
Approximately one in every 400 to 600 children and adolescents has type 1 diabetes.
Clinic-based reports and regional studies indicate that type 2 diabetes is becoming more common among Native American/American Indians, African Americans, and Hispanics and Latinos.
Prevalence of Diabetes Among People 20 Years or Older
Age 20 Years or Older: 20.6 million. 9.6% of all people in this age group have diabetes.
Age 60 Years or Older: 10.3 million. 20.9% of all people in this age group have diabetes.
Men: 10.9 million. 10.5% of all men aged 20 years or older have diabetes. The projected increase of diabetes in men from 2005 to the year 2050 is 174%.
Women: 9.7 million. 8.8% of all women aged 20 years or older have diabetes. The projected increase of diabetes in women from 2005 to the year 2050 is 220%.
Prevalence of Diabetes by Race/Ethnicity Among People 20 Years or Older
Non-Hispanic Whites: 13.1 million. 8.7% of all non-Hispanic whites aged 20 years or older have diabetes. The projected increase of diabetes in non-Hispanic whites from 2005 to the year 2050 is 113%.
Non-Hispanic Blacks: 3.2 million. 13.3% of all non-Hispanic blacks aged 20 years or older have diabetes. On average, non-Hispanic blacks are 1.8 times more likely to have diabetes than non-Hispanic whites of similar age. The projected increase of diabetes in non-Hispanic blacks from 2005 to the year 2050 is 208%.
Hispanic/Latino Americans: After adjusting for population age differences, Mexican Americans, the largest Hispanic/Latino Americans subgroup, are 1.7 times as likely to have diabetes as non-Hispanic whites. If the prevalence of
diabetes among Mexican Americans was applied to the total Hispanic/Latino population, about 2.5 million (9.5%) Hispanic/Latino Americans aged 20 years or older would have diabetes. Sufficient data are not available to derive estimates of the total prevalence of diabetes (both diagnosed and undiagnosed diabetes) for other Hispanic/Latino groups. However, residents of Puerto Rico are 1.8 times as likely to have diagnosed diabetes as U.S. non-Hispanic whites.
American Indians and Alaska Natives who Receive Care From the Indian Health Service (IHS): 99,500. 12.8% of American Indians and Alaska Natives aged 20 years or older receiving care from IHS have diabetes. On average, American Indians and Alaska Natives are 2.2 times more likely to have diabetes than non-Hispanic whites of similar age.
Asian Americans and Native Hawaiian or Other Pacific Islanders: The total prevalence of diabetes (both diagnosed and undiagnosed diabetes) is not available for Asian Americans or Pacific Islanders. However, in Hawaii, Asians, Native Hawaiians, and other Pacific Islanders aged 20 years or older are more than 2 times as likely to have diagnosed diabetes as whites after adjusting for population age differences. Similarly, in California, Asians were 1.5 times as likely to have diagnosed diabetes as non-Hispanic whites. Other groups within these populations also have increased risk for diabetes.
Complications of Diabetes
Heart Disease and Stroke
Heart disease and stroke account for about 65% 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 with diabetes.
High Blood Pressure
About 73% of adults with diabetes have blood pressure greater than or equal to 130/80 millimeters of mercury (mm Hg) or use prescription medications for hypertension.
Diabetes is the leading cause of new cases of blindness among adults 20-74 years old.
Diabetic retinopathy causes from 12,000 to 24,000 new cases of blindness each year.
Diabetes is the leading cause of kidney failure, accounting for 44% of new cases in 2002.
In 2002, 44,400 people with diabetes began treatment for end-stage kidney disease in the United States and Puerto Rico.
In 2002, a total of 153,730 people with end-stage kidney disease due to diabetes were living on chronic dialysis or with a kidney transplant in the United States and Puerto Rico.
Nervous System Disease
About 60% to 70% of people with diabetes have mild to severe 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% of people with diabetes aged 40 years or older have impaired sensation in the feet (i.e., at least one area that lacks feeling).
Severe forms of diabetic nerve disease are a major contributing cause of lower-extremity amputations.
More than 60% of nontraumatic lower-limb amputations in the United States 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 diabetes. Among young adults, those with diabetes have about twice the risk of those without diabetes.
Almost one-third of people with diabetes have severe periodontal disease 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 first trimester of pregnancy can cause major birth defects in 5% to 10% of pregnancies and spontaneous abortions in 15% to 20% of pregnancies.
Poorly controlled diabetes during the second and third trimesters of pregnancy can result in excessively large babies, posing a risk to both mother and child.
Uncontrolled diabetes often leads to biochemical imbalances that can cause acute life-threatening events, such as diabetic ketoacidosis and hyperosmolar (nonketotic) coma.
People with diabetes are more susceptible to many other illnesses 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.
Cost of Diabetes in the United States
Total (Direct and Indirect):$132 billion
Direct Medical Costs: $92 billion
Indirect Costs:$40 billion (disability, work loss, premature mortality)
Treatment of Diabetes
In order to survive, people with type 1 diabetes must have insulin delivered by a pump or injections.
Many people with type 2 diabetes can control their blood glucose by following a careful diet and exercise program, losing excess weight, and taking oral medication.
Many people with diabetes also need to take medications to control their cholesterol and blood pressure.
Prevention of Diabetes
Research studies in the United States and abroad have found that lifestyle changes can prevent or delay the onset of type 2 diabetes among high-risk adults. Lifestyle interventions included diet and moderate-intensity physical activity (such as walking for 2 ½ hours each week).
These data are based on a study by the Lewin Group, Inc., for the American Diabetes Association and are 2002 estimates of both the direct (cost of medical care and services) and indirect costs (costs of short-term and permanent disability and of premature death) attributable to diabetes. This study used a specific cost-of-disease methodology to estimate the health care costs due to diabetes.
