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 the data periods 2004-2010, 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 and 2010. 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 and 2008-2010, and on maps and in data tables by county (except counties in Alaska), health service area (HSA) and state. The most recent estimates (2008-2010) are also released in State Cancer Profiles. Click on the map to view data values and confidence intervals for individual regions.
Common Quantiles are calculated by pooling all years of data for the same outcome, geography and sex groupings. Use common quantiles to better show changes across different years for the same outcome compared to using quantiles calculated based on individual year's data.
