About BRFSS
The Behavioral Risk Factor Surveillance System (BRFSS) is the largest, continuously conducted telephone health survey in the world. It enables the Center for Disease Control and Prevention (CDC), state health departments, and other health agencies to monitor modifiable risk factors for chronic diseases and other leading causes of death.
BRFSS questions and topics have changed periodically to reflect:
- Scientific advances which produce new guidelines for screening and treatment for various conditions or chronic diseases
- Emerging public health concerns
- Improvements in questionnaire design
Therefore, questions for some health topic areas may not have been asked in every year. Some topics are now covered on a yearly basis, whereas others are asked on a rotating basis, depending in part on how rapidly the prevalence is likely to change. Many questions were designed and tested by CDC; some are added by the state programs and were developed through other research work.
