Prevalence of Prediabetes Among Adults

  • An estimated 88 million adults aged 18 years or older had prediabetes in 2018 (Table 3).
  • Among US adults aged 18 years or older, crude estimates for 2013–2016 were:
    • 34.5% of all US adults had prediabetes, based on their fasting glucose or A1C level (Table 3).
    • 10.5% of adults had prediabetes based on both elevated fasting plasma glucose and A1C levels (Appendix Table 5).
    • 15.3% of adults with prediabetes reported being told by a health professional that they had this condition (Table 3).

Among US adults aged 18 years or older, age-adjusted data for 2013–2016 indicated:

  • A higher percentage of men (37.4%) than women (29.2%) had prediabetes (Appendix Table 6).
  • Prevalence of prediabetes was similar among all racial/ethnic groups and education levels (Appendix Table 6).

Trends in Prevalence of Prediabetes Among Adults

  • There were no significant changes in age-adjusted prevalence of prediabetes from 2005–2008 to 2013–2016 (Appendix Table 7). About one-third of US adults had prediabetes over the entire period.
  • Among adults with prediabetes, the age-adjusted percentage aware that they had this condition doubled from 6.5% to 13.3% between 2005–2008 and 2013–2016 (Appendix Table 7).
