Diabetes is a disorder in how the body uses glucose, a sugar that serves as the body’s fuel. In type 1 diabetes, the body doesn’t make insulin, a hormone that triggers cells throughout the body to take up glucose from blood.
In type 2 diabetes—the most common type—the body doesn’t make or use insulin well. Both types can lead to heart, kidney, nerve, and eye diseases over time.
Hispanic Americans had the highest prevalence of diabetes at 19-23%, with up to 49% of that undiagnosed. About 21-22% of non-Hispanic black adults had diabetes, with up to 37% undiagnosed.
To assess how common diabetes is, researchers at NIH’s National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) analyzed data collected in CDC’s National Health and Nutrition Examination Survey (NHANES). NHANES is a periodic survey of a representative sample of the U.S. population.
Recent surveys included blood tests and other measurements. The researchers, led by Drs. Andy Menke and Catherine Cowie, examined data gathered from almost 2,800 people during the 2011-2012 survey cycle. The study was published on September 8, 2015, in the Journal of the American Medical Association.
