Prevalence of Prediabetes Among Adults
‹View Table of Contents
- An estimated 96 million adults aged 18 years or older had prediabetes in 2019 (Table 3).
- Among US adults aged 18 years or older, crude estimates for 2017–2020 were:
- 38.0% of all US adults had prediabetes, based on their fasting glucose or A1C level (Table 3).
- 19.0% 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 2017–2020 indicated:
- 10.8% of adults had prediabetes, based on both elevated fasting plasma glucose and A1C levels (Appendix Table 5).
- A higher percentage of men (41.0%) than women (32.0%) had prediabetes, based on their fasting glucose or A1C level (Appendix Table 6).
- Prevalence of prediabetes (based on fasting glucose or A1C level) 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 2017–2020 (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 increased from 6.5% in 2005–2008 to 17.4% in 2017–2020 (Appendix Table 7).
