The population at high risk for developing diabetes is defined as persons who have prediabetes—this includes persons who do not have doctor diagnosed diabetes (do not respond yes to ever being diagnosed with diabetes or sugar diabetes) and have either a fasting blood glucose level of greater than or equal to 100 or less than 126 mg/dl or have an A1c level of ≥5.7% to <6.5%.
Persons are considered not to have diagnosed pre-diabetes if they respond "no" to the question "have you ever been told by a doctor you have pre-diabetes" and "no" to the question "have you ever been told by a doctor that you have diabetes." Women who report that the only time they have been diagnosed with diabetes was during pregnancy (gestational diabetes) are also considered not to have diagnosed diabetes. Data for HbA1c are available for the whole sample, but data for fasting glucose are only measured for the morning examination session. For this analysis the cohort examined is restricted to persons in the AM exam session only. Backward calibration equations were used to account for changes in plasma glucose laboratory procedures over time. This indicator uses age-adjustment groups: Total: 18-29, 30-39, 40-49, 50-59, 60-69, 70-79, 80.
