California Behavior Risk Factor Surveillance System

The Behavior Risk Factor Surveillance System (BRFSS) was established in 1984 by the Centers for Disease Control and Prevention (CDC). It 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.

In 2014, we partnered with the California Department of Public health (CDPH) to conduct the California BRFSS. BRFSS provides the state of California and the nation with a yearly assessment of a variety of public health topics, including: demographic information, cancer prevalence and screening, tobacco use and control, gender specific health screenings (e.g., breast and prostate cancer), asthma diagnosis, alcohol consumption, and other current health concerns (e.g., flu and pneumococcal vaccinations).

The California BRFSS utilizes random digit dialing of California landline and cell phone numbers, and conducts interviews in English and Spanish. Data is weighted to the California population, allowing researchers to accurately estimate the prevalence of health conditions and behaviors. BRFSS data is available for public use.
