Methodology Notes

Persons are considered to have diabetes if they respond ‘yes’ to the question. Those who respond borderline are counted as ‘no’. Women who report that the only time they have been diagnosed with diabetes was during pregnancy (gestational diabetes) are also excluded.

Trend Issues
Hemoglobin A1c results for 2007-2008 (GHB_E) and 2009-2010 (GHB_F) were temporarily withdrawn in November 2011 to evaluate a shift to the right (increased values) in the distribution of Hemoglobin A1c in 2007-2010 compared to 1999-2006. After careful evaluation of participant data, laboratory quality control data and non-NHANES A1c studies, a cause for this shift in the distribution of Hemoglobin A1c could not be identified. Therefore, the Hemoglobin A1c data for 2007-2008 (GHB_E) and 2009-2010 (GHB_F) were re-released in March 2012 without changes to the data. The user will need to carefully consider the information presented in this analytic note when analyzing Hemoglobin A1c data from 1999-2010.
