The Arizona Behavioral Risk Factor Survey (BRFS), initiated in 1984, is a federally funded telephone survey conducted on a monthly basis of 4,700 randomly selected adult Arizonans to collect data on lifestyle risk factors contributing to the leading causes of death and chronic diseases. This surveillance can be used to monitor the Healthy People 2010 objectives for smoking, overweight, high blood pressure, exercise, flu/pneumonia vaccination, cholesterol, seat belt use, fruit/vegetable consumption and other risk factors so that intervention priorities can be established and the long-term impact of health promotion programs can be monitored.Since BRFS is used nationwide, comparisons can be made to other states and the national average. Interactive Web pages on the CDC BRFS site provide trend data, prevalence data, comparative State maps, as well as risk trend data for selected metropolitan and micropolitan areas. The Arizona BRFS utilizes the services of ICF Macro, Computer Assisted Telephone Interviewing (CATI) System for respondent interviewing. A core questionnaire provided by CDC of approximately 75 questions may also include state-added questions or various standard modules. ORC Macro provides monthly data files to the Arizona BRFS Coordinator to edit for out of range values and errors. Corrections are made before the data are sent to CDC for final edit checks, weighting and tabulation. The annual data tables are sent to the Arizona BRFS program and reports are prepared for distribution. Reports are published based on Arizona's BRFS data to provide timely and in depth analysis of chronic disease risk factors.
