Description
For sample adults aged 40 years and older who ever had a colonoscopy (COLEV), COLLGYRR2 is a recoded variable that reports the time since the respondent's most recent colonoscopy using the same method as the 2005 survey.
For more information, please see COLEV.
[show more]This recoded variable is based on the following variables:
- COLLNO: Time since last colonoscopy: units
- COLLTP: Time since last colonoscopy: time period
- COLLDMO: Calendar month of last colonoscopy
- COLLDYR: Year of last colonoscopy
- COLLESTY: Time since last colonoscopy: grouped year estimate
The 2010 and 2015 Cancer Layout files note that, "This is a time category recode for the time since the most recent colonoscopy. All available information was used and the recoded variable was pre-filled with the response to the time category question first, if available. These data are provided by the respondent and are not imputed."
There is a similar variable that also reports the time since the respondent's most recent colonoscopy, COLLGYRR1, using the same method as the 2000 survey.
