Indicator information

65+: Colorectal cancer screening--sigmoidoscopy

Definition: Percentage of people aged 65 and over who had a sigmoidoscopy or colonoscopy for colorectal cancer screening within the past five years, two-year average

Notes: The data are from Behavioral Risk Factor Surveillance Survey (BRFSS). Respondents were asked the questions: "Sigmoidoscopy and colonoscopy are exams in which a tube is inserted in the rectum to view the bowel for signs for cancer or other health problems. Have you ever had either of these exams?" and "How long has it been since you had your last sigmoidoscopy or colonoscopy?" These questions were asked every odd year of the survey before 2001, and every even year since 2002. Percentage is a 2-year average, which helps to reduce the year-to-year fluctuation due to small numbers. Percentage is reported under the year at the midpoint of the 3-year period; e.g., the average of 1999 and 2001 was reported under 2000. National data is the median of the 50 states and the District of Columbia.
