Half of U.S. Adults Have Diabetes or Prediabetes

An estimated 12 percent of American adults have full blown diabetes, while another 37 to 38 percent have prediabetes, according to a study published in JAMA (Journal of the American Medical Association). The good news is that level of diabetes may be leveling off, the research concludes.

Utilizing data from the National Health and Nutrition Examination Survey (NHANES), the researchers estimated diabetes trends from the years of 1988 to 2012. Their findings showed:

  • In the overall 2011-2012 population, the prevalence was 14.3 percent for total diabetes, 9.1 percent for diagnosed diabetes, 5.2 percent for undiagnosed diabetes, and 38 percent for prediabetes. Among those with diabetes, 36.4 percent were undiagnosed.
  • The prevalence of total diabetes was higher among non-Hispanic blacks (21.8 percent), Asians (20.6 percent), and Hispanics (22.6 percent) when compared to non-Hispanic whites
  • Prediabetes was most prevalent among non-Hispanic white and non-Hispanic black people.
  • The highest cases of undiagnosed diabetes were in the non-Hispanic Asian (50.9 percent) and Hispanic (49 percent) population.
  • The prevalence of total diabetes increased between 1988 and 1994 and 2011 and 2012, but changed little between 2007 – 2008 and 2011 – 2012, suggesting a plateauing of the condition.
