Data Source: 2010 Michigan Behavioral Risk Factor Surveillance System. Bureau of Epidemiology, Division of Genomics, Perinatal Health and Chronic Disease Epidemiology, Michigan Department of Community Health. Methods and Limitations: The Michigan Behavioral Risk Factor Surveillance System (MI BRFSS) comprises annual, state-level telephone surveys of the non-institutionalized adult population, 18 years and older. The MI BRFSS provides self-reported information on behavioral risk factors for disease and on preventive health practices within the state. The data are limited by potential recall bias and may be under- or over- reported. Validity of self-reported glucose testing has not been measured. Prediabetes Awareness Indicator: Respondents were considered to have prediabetes if they answered "yes" to the question "Has a doctor ever told you that you have prediabetes?" or "no, prediabetes or borderline" to the question "Has a doctor ever told you that you have diabetes?" Since self-reported prediabetes is low compared to estimates from laboratory data, this measure is considered a gauge of disease awareness. |
Prevalence
There is no state surveillance of prediabetes. The best information available is from a national study, the National Health and Nutrition Examination Survey (NHANES). NHANES uses mobile labs to collect blood specimens for fasting blood glucose tests; therefore, the prediabetes prevalence estimates encompass both diagnosed and undiagnosed cases. Nationally, only 7.3% of people were aware of their prediabetes status (Geiss et al. Am J of Prev Med, April 2010). The prevalence rates published in the public domain are reprinted here (in abbreviated format).
