BRFSS surveys are conducted in all 50 states, the District of Columbia (DC), and selected U.S. territories (Puerto Rico, the U.S. Virgin Islands, and Guam).2 BRFSS uses a multistage sampling design based on random-digit–dialing methods to select a representative sample of the noninstitutionalized, civilian population aged ≥18 years in each state or territory. Details on the design, random sampling procedures, and reliability and validity of measures used in BRFSS have been described previously.3,4 In 2006, the median response rate among states, based on Council of American Survey Research Organizations (CASRO) guidelines, was 51.4% (range: 35.1%-66.0%). Data were weighted to account for probability of selection and to match the age-, race/ethnicity-, and sex-specific populations from annually adjusted intercensal estimates. Statistical significance was determined by nonoverlap of 95% confidence intervals. Estimates were considered unstable if the unweighted sample size for the subgroup was less than 50. In 2006, interviews with 92,808 persons aged ≥65 years were completed. Data from all 50 states, DC, Puerto Rico, and the U.S. Virgin Islands are included in this report.
