Randomized Controlled Trial Multicenter Study
Differences in A1C by race and ethnicity among patients with impaired glucose tolerance in the Diabetes Prevention Program.
We sought to examine racial and ethnic differences in A1C in individuals with impaired glucose tolerance (IGT). ⋯ A1C levels are higher among U.S. racial and ethnic minority groups with IGT after adjustment for factors likely to affect glycemia. Among patients with IGT, A1C may not be valid for assessing and comparing glycemic control across racial and ethnic groups or as an indicator of health care disparities.
