Behavioral Risk Factor Surveillance System
The Colorado Behavioral Risk Factor Surveillance System (BRFSS) is a system of telephone
surveys sponsored by the Centers for Disease
Control to monitor lifestyles and behaviors related to the leading causes
of mortality and morbidity. In recent years, health professionals and the public
have become increasingly aware of the role of such lifestyle factors as cigarette
smoking, overweight, sedentary lifestyle, and the nonuse of seat belts in contributing
to injury, illness and death.
In 1981, the Centers for Disease Control began using the Behavioral Risk Factor
Surveillance System as a method of estimating the prevalence of high risk behaviors
and lifestyle factors that contribute to death and disease. Colorado participated
in this project with point in time surveys in 1982 and 1987. The Survey Research
Unit of the Health Statistics and Evaluation Branch of the Colorado Department of Public Health
and Environment began collecting data on a monthly basis in January 1990. The Survey
Research Unit now completes more than 1,000 BRFSS surveys a months with adult residents
