In 2013, the Illinois ACEs Response Collaborative successfully petitioned the Illinois Department of Public Health to include an ACE module in the State’s Behavioral Risk Factor Surveillance System (BRFSS)—a CDC-developed survey that collects information on health risk behaviors, chronic diseases, use of preventive health practices, and health access. Our report presents findings from the 2013 BRFSS and examines the prevalence of ACEs among adults in Illinois and Chicago, including assessing racial/ethnic and gender differences, and the association of ACEs with negative health outcomes.
