The BRFSS, also known as the Virginia Adult Health Survey (VAHS), is a telephone survey conducted by the health departments of all states, the District of Columbia, Puerto Rico, the U.S. Virgin Islands and Guam with assistance from CDC. The BRFSS is the largest continuously conducted telephone health surveillance system in the world.
States use BRFSS data to:
- Identify emerging health problems
- Establish health objectives and track their progress
- Develop and evaluate public health policies and programs to address identified problems
The BRFSS is the primary source of information for states and the nation on the health-related behaviors of adults. States collect data through monthly interviews with adults aged 18 years or older. BRFSS interviewers ask questions related to behaviors that are associated with preventable chronic diseases, injuries and infectious diseases.
