For the colorectal endoscopy, a person 50 years of age or older must have reported having at least one colorectal endoscopy (proctoscopy, sigmoidoscopy or colonoscopy) in his/her life.
For the data periods 2004-2010, the colorectal endoscopy questions were asked in BRFSS in the even years as part of the core questionnaire for all states, and in NHIS in 2005, 2008, and 2010. The questions were worded in similar ways on the two surveys.
Available estimates are for the time periods 2004-2007 and 2008-2010, and on maps and in data tables by county (except counties in Alaska), health service area (HSA) and state. Click on the map to view data values and confidence intervals for individual regions.
Endoscopy estimates are no longer produced for 2011 and forward because definition changes due to updated U.S. Preventive Services Task Force (USPSTF) recommendations on colorectal cancer screening. Estimates for colonoscopy are released instead.
