Diabetes

What to know

  • About 38 million U.S. adults have diabetes, and 1 in 5 of them don't know it.
  • Diabetes is a long-lasting condition that can lead to serious disease and death over time.
  • There is no cure for diabetes, but we can prevent or manage the most common type (type 2) by eating healthy, being active, and keeping a healthy weight.
  • Public health efforts can offer proven lifestyle change programs to reduce diabetes risk for people.

Definition details

Population
All adults.
Numerator

Denominator
All adults.
Measure
Prevalence (crude and age-adjusted).
Time Period of Case Definition
Lifetime.
Summary
In 2021 in the U.S., 8.5% of the U.S. adult population aged ≥ 18 years had diagnosed diabetes.1 For the same year, the overall median prevalence for all 50 states, District of Columbia, and territories was 11.1%.2 Substantial differences in diabetes prevalence exist by age, race, and ethnicity.1-3 The burden of diabetes in the U.S. has increased with the growing prevalence of obesity.3 Multiple long-term complications of diabetes can be prevented by managing blood glucose, blood lipids, and blood pressure regularly, eating healthy foods, being physically active, and by screening and early treatment for eye, foot, and kidney abnormalities.4
Notes
About one fifth of U.S. adults with diabetes are undiagnosed.5 As self-awareness of having diabetes is low, the prevalence of diabetes may be underestimated.

Population
Women who have had a recent live birth.
Numerator
Women who reported that a healthcare provider told them during their most recent pregnancy that they had gestational diabetes (diabetes that started during their most recent pregnancy).
Denominator
Women who reported that a healthcare provider did or did not tell them during their most recent pregnancy that they had gestational diabetes (diabetes that started during their most recent pregnancy).
Measure
Prevalence (crude).
Time Period of Case Definition
During the pregnancy resulting in the most recent live birth.
Summary
Gestational diabetes is associated with pregnancy complications, including increased rates of large for gestational age birth, preeclampsia, and pre-term birth.1 Women with gestational diabetes have seven times higher risk of developing type 2 diabetes within 10 years of the gestational diabetes-affected pregnancy.2 Children born to mothers with gestational diabetes are also at increased risk of developing type 2 diabetes.3 Lifestyle interventions, such as the National Diabetes Prevention Program, have been shown to reduce risk of developing type 2 diabetes in high risk individuals.4
Notes
Because there are multiple recommendations and guidelines for gestational diabetes screening, diagnostic tests, and threshold values,5 changes in prevalence estimates reflect variation in clinical practice or true changes in the proportion of women with gestational diabetes.6 The numerator above reflects the question to be asked beginning with 2023 births (PRAMS Phase 9). Data from PRAMS Phase 8 (2016-2022 births) results from a slightly different question. The numerator for Phase 8 data is “Women who reported that during their most recent pregnancy they had gestational diabetes (diabetes that started during their most recent pregnancy).”

Summary
During 2021, diabetes was the eighth leading cause of death in the United States, resulting in more than 103,000 deaths.1 Diabetes was nearly three times as likely to be listed as a contributing cause of death than as the underlying cause of death in 2021.2 Multiple long-term complications of diabetes can be prevented by managing blood glucose, blood lipids, and blood pressure regularly, eating healthy foods, being physically active, and by screening and early treatment for eye, foot, and kidney abnormalities.3 Ways to prevent complications include offering diabetes self-management education and support services along with provision of adequate and timely screening and medical care.3
Notes
About one fifth of U.S. adults with diabetes are undiagnosed.4 Diabetes is likely to be underreported as a cause of death, listed only on death certificates of about 40% of decedents who actually had diabetes.5 Causes of death and other variables listed on the death certificate might also be inaccurate or incomplete.

Summary
During 2021, diabetic ketoacidosis (DKA) was listed as the underlying cause of death for about 5,400 decedents.1 DKA is more frequent among people with type 1 diabetes than among people with type 2 diabetes. Although it is a life-threatening condition for people with diabetes, DKA is preventable through improved patient and caregiver education, effective diabetes self-management, proper medication adherence, and provision of adequate and timely medical care.2,3
Notes
The awareness of having the disease (diabetes) is higher among people with type 1 diabetes than among those with type 2 diabetes; however, about one fifth of U.S. adults with diabetes are undiagnosed.4 Although DKA is an acute event and expected to be listed more frequently as the underlying cause of death, diabetes is underreported as a cause of death and is listed only on death certificates of about 40% of decedents who actually had diabetes.5 Causes of death and other variables listed on the death certificate might also be inaccurate or incomplete.
