Behavioral Risk Factor Surveillance System

The Wisconsin Behavioral Risk Factor Surveillance System (BRFSS) is a telephone survey conducted by state health departments in collaboration with the CDC (Centers for Disease Control and Prevention).

Established in 1984, BRFSS collects data in all 50 states as well as the District of Columbia and three U.S. territories. BRFSS completes more than 400,000 adult interviews each year, making it the largest continuously conducted health survey system in the world.

Each year, we interview approximately 9,000 adult Wisconsinites selected at random for the BRFSS. We collect information on important statewide and national topics, such as disparities in health and health care, trends in chronic diseases, and behaviors that impact the risk of health challenges. The results are used to assess progress toward achieving public health goals and to plan, support, and evaluate programs promoting public health.
