CDC’s Behavioral Risk Factor Surveillance System Provides Asthma and Health-Related Risk Behavior Data

The Centers for Disease Control and Prevention’s Behavioral Risk Factor Surveillance System (BRFSS) is the nation’s premier system of health-related telephone surveys that collect state data about U.S. residents regarding their health-related risk behaviors, chronic health conditions, and use of preventive services. Established in 1984 with 15 states, BRFSS now 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. BRFSS includes prevalence data on asthma. For example, the 2016 data set indicates that, among adults who have been told they have asthma, South Dakota has the lowest prevalence rate at 9.25%, while Hawaii and Puerto Rico claim the top spots with prevalence rates over 17%.
