Behavioral Risk Factor Surveillance System

The Maryland Behavioral Risk Factor Surveillance System (BRFSS) is an ongoing telephone surveillance program designed to collect data on the behaviors and conditions that place Maryland residents  at risk for chronic diseases, injuries, and preventable infectious diseases. The typical sample size is 12,000 non-institutionalized Maryland residents age 18 and older per year.

The data collected are used to characterize health behaviors, ascertain the prevalence of risk factors, and target demographic groups with increased needs. Knowing the type and frequency of health issues and behavioral risk factors  enables public health professionals to devise and implement programs geared toward the prevention of chronic diseases, injury, and disability, and to reduce health disparities.
The Maryland BRFSS is conducted under guidance from the Centers for Diseases Control and Prevention (CDC). For more information regarding the BRFSS survey and its use in all 50 states and several territories, please visit
Maryland BRFSS data from 1995 through the present can be found on the Maryland BRFSS website. Data can be analyzed by year, by jurisdiction, and by a number of demographic variables.
