About one third of Americans have prediabetes, but 90% are not even aware of their condition. One study found that an estimated 53.5 million adults with a high body mass index (BMI) and high score on the ADA risk test but no specific diagnosis of prediabetes were less likely to receive advice or referrals for prevention. Specifically, just half (50.6%) reported receiving any diabetes risk-reduction advice or referral, and less than 1% (0.4%) reported referral to diabetes prevention programs.
Prediabetes will progress to overt type 2 diabetes in about one third of individuals within a few years. Although some people will revert to having normal glucose tolerance during this time, many others will remain prediabetic or develop overt diabetes later in life.
The global prevalence of IGT is estimated to reach 8.3% of the adult population, or about 587 million individuals, by 2045. Currently, there is no significant difference in prevalence of IGT between men and women. These estimates are based solely on the IGT test, so the prevalence of IGT may be higher if additional criteria are taken into consideration.
