The Role of the Behavioral Risk Factor Surveillance System in Disease Control and Prevention


Ali Mokdad, PhD
Professor, Global Health
Adjunct Professor, Epidemiology

Dr. Ali Mokdad leads the survey and surveillance activities at the Institute for Health Metrics and Evaluation (IHME)



The Behavioral Risk Factor Surveillance System (BRFSS) is a state-based system of health surveys that collects information on health risk behaviors, preventive health practices, and health care access primarily related to chronic disease and injury. States use BRFSS data to identify emerging health problems, establish health objectives and track their progress toward meeting these objectives, and develop and evaluate public health policies and programs designed to address identified problems. The BRFSS is the primary source of data for local entities, states, and the nation on the health-related behaviors of adults.  Due to the rapid changes in telecommunication in the US, BRFSS has designed and conducted innovative pilot studies to advance the current BRFSS methodology.  The research has also identified and addressed some potential threats to the validity and reliability of BRFSS data that might affect survey participation and data quality.  The presentation will review BRFSS methodology and provide examples of improvements in the system and its use in public health program.
