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.
