In 1997, all 50 states, the District of Columbia, and Puerto Rico participated in the BRFSS, a population-based, random-digit-dialed telephone survey of the noninstitutionalized, U.S. population aged ≥18 years. A total of 52,754 persons aged ≥50 years were asked whether they had ever had a blood stool test (FOBT) using a home kit and whether they had ever had a sigmoidoscopy or proctoscopy, and when the last test had been performed. Responses coded as "Don't know/Not sure" or "Refused" were excluded from the analyses (approximately 3%). Data were weighted to the age, sex, and racial/ethnic distribution of each state's adult population using 1990 census or intercensal estimates. Proportions, standard errors, and 95% confidence intervals were calculated using SAS and SUDAAN. Data were aggregated across states. Aggregated and state-level data are presented for the proportion of respondents aged ≥50 years who reported receiving FOBT or sigmoidoscopy/proctoscopy.
