From the 2008 Behavioral Risk Factor Surveillance System:
A test for "A one C" measures the average level of blood sugar over the past three months. About how many times in the past 12 months has a doctor, nurse, or other health professional checked you for "A one C"?
Variable Name: CHKHEMO3
Have you ever been told by a doctor that you have diabetes? (If "Yes" and respondent is female, ask "Was this only when you were pregnant?")
Variable Name: DIABETE2
Persons are considered to have diabetes if they have ever been told by a doctor or health professional that they have diabetes or sugar diabetes. Women who report that the only time they have been diagnosed with diabetes was during pregnancy (gestational diabetes) are excluded. Persons who report that they have pre-diabetes or borderline diabetes are also excluded from the measure. Persons are considered to have been measured for glycosylated hemoglobin if they have been checked for HbA1c two or more times in the past 12 months.
