Although the prediabetes prevalence rate increased by 4.8 percentage points between 2010 and 2020, access to the National Diabetes Prevention Program remained limited, with only 3% of people with prediabetes participating in the program, according to a recent Health Affairs study. The researchers estimated 13.5% prevalence of diagnosed prediabetes and 30% of potentially undiagnosed prediabetes in 2020, using two national surveys.
The National Diabetes Prevention Program — an intensive 12-month, group-based, lifestyle intervention to prevent or delay type 2 diabetes — remained underused and undersupplied. Only 5% of patients diagnosed with prediabetes were referred to such a program. In general, men were more likely to be referred but less likely to participate than women.
