• Resumen

  • To compare A1C and fasting glucose for the diagnosis of diabetes among U.S. Adults. This study included 6, 890 adults (¡Ý20 years of age) from the 1999-2006 National Health and Nutrition Examination Survey without a self-reported history of diabetes who had fasted ¡Ý9 h. A1C ¡Ý6.5% and fasting glucose ¡Ý126 mg/dl were used, separately, to define diabetes. Overall, 1.8% of U.S. Adults had A1C ¡Ý6.5% and fasting glucose ¡Ý126 mg/dl, 0.5% had A1C ¡Ý6.5% and fasting glucose <126 mg/dl, and 1.8% had A1C <6.5% and fasting glucose ¡Ý126 mg/dl. Compared with individuals with A1C <6.5% and fasting glucose ¡Ý126 mg/dl, individuals with A1C ¡Ý6.5% and fasting glucose <126 mg/dl were younger, more likely to be non-Hispanic black, had lower Hb levels, and had higher C-reactive protein. A1C ¡Ý6.5% demonstrates reasonable agreement with fasting glucose for diagnosing diabetes among U.S. Adults.
