For home-based FOBT, a person 50 years of age or older must have reported having at least one FOBT using a home test kit in his/her life. Furthermore, he/she should have had the most recent one within the last two years by the time of interview.
For home-based FOBT, a person aged 50-75 must have reported having at least one FOBT using a home test kit in his/her life, excluding those who had a colonoscopy within the past 10 years. Furthermore, he/she should have had the most recent one within the past year by the time of interview.
For the data periods 2004-2019, the home-based FOBT questions were asked in BRFSS in the even years as part of the core questionnaire for all states, and in NHIS in 2005, 2008, 2010, 2013, 2015, 2018, and 2019. The questions were worded in similar ways on the two surveys, except that for the time since most recent home-based FOBT test question, NHIS asked for exact year, date or time period, while BRFSS only asked for time period.
Available estimates are for the time periods 2004-2007, 2008-2010, 2011-2016, and 2017-2019 and on maps and in data tables by county (except counties in Alaska before 2011), health service area (HSA) and state. The most recent estimates (2017-2019) are also released in State Cancer Profiles. Click on the map to view data values and confidence intervals for individual regions.
For 2011 and forward, the definition of home-based FOBT screening is updated to match the updated U.S. Preventive Services Task Force (USPSTF) recommendations on colorectal cancer screening.
