Behavioral risk factors are associated with the ten leading causes of death in the United States and Alaska. Surveillance of behavioral risk factors allows us to monitor trends in health behavior and particularly enables us to measure progress toward reaching the "Healthy People 2000 Health Promotion and Disease Prevention Objectives" for the nation. It can also provide the basis for launching and evaluating programs designed to reduce the prevalence of unhealthy behaviors and attain Year 2000 health goals. The CDC initiated the Behavioral Risk Factor Surveillance System (BRFSS) in 1984, by which 17 states began collecting behavioral risk data through monthly telephone surveys. The Behavioral Risk Factor Surveillance System was implemented in Alaska in 1990. Each month, 165 adults ages 18 and older are interviewed regarding their health and day-to-day living habits. This report contains the 1999 survey results. These surveys were conducted from January through December 1999, for a total sample size of 2,051 interviews. The Division of Public Health BRFSS continues to conduct monthly telephone surveys each year.
