This page includes data from the St. Norbert College Strategic Research Institute and the U.S. Centers for Disease Control and Prevention (CDC) on prevalence of diabetes. The Behavioral Risk Factor Surveillance System (BRFSS) survey asks adults to report if they have ever been diagnosed with diabetes, a disease caused by the pancreas not creating enough insulin to take the sugar out of one’s bloodstream and convert it into energy. There are multiple types of diabetes: Type 1, Type 2 and Prediabetes. Prediabetes, or borderline diabetes, is closely tied to obesity and, if undiagnosed or untreated, can develop into type 2 diabetes. The BRFSS is administered by the Wisconsin Department of Health Services in conjunction with the CDC.
