Codes and Frequencies
For sample adults aged 40 and older, BSTHEV reports if the person had ever had a blood stool test using a home test kit.
BSTHEV is one of a series of periodically-asked questions about cancer screening. Other variables containing information about blood stool or FIT tests include:
- BSTHLDMO: Month date of most recent home blood stool test
- BSTHLDYR: Date of last home blood stool test: Year
- BSTHLNO: Time since home blood stool test: Number of units
- BSTHLTP: Time since home blood stool test: Time period
- BSTHGYRR: Time since home blood stool test: Grouped years
- BSTHLGYRE: Time since home blood stool test: Estimated years
- BSTHLGYRR1: Time since home blood stool test: Grouped year recode 1 (2000 method)
- BSTHLGYRR2: Time since home blood stool test: Grouped year recode 2 (2005 method)
- BSTHYL: Reason for most recent home blood stool test
The 2018 Field Representatives Manual defined the "blood stool or occult blood test, or fecal immunochemical or FIT test," as a type of test that checks for colon cancer by determining "whether you have blood in your stool or bowel movement. These tests can be done at home using a kit."
Aside from slight wording changes, this variable is comparable over time. In 2015, the wording of the question changed slightly to more inclusive language. Prior to 2015, respondents were asked whether they ever had "a blood stool test, using a HOME test kit?" Beginning in 2015, respondents were asked whether they had ever had "a blood stool or FIT test, using a HOME test kit?"
