Behavioral Risk Factor Surveillance System (BRFSS) as established in 1984 by Centers for Disease Control and Prevention (CDC). It was initially designed to collect state-level data that allowed those in the state to estimate prevalence for regions within their respective states concerning major behavioral risks among adults associated with premature morbidity and mortality. The idea was to collect data on actual behaviors that could be useful for planning, initiating, supporting and evaluating health promotion and disease prevention.

Currently, it's the largest continuously conducted telephone health survey in the world. It enabled CDC, state health departments, other health and education agencies to monitor risk behaviors related to chronic diseases, injuries, and death. Also, is one of the most effective tools used today in preventing disease and promoting health.
