Codes and Frequencies
For sample adults aged 40 years and older who ever had a colonoscopy (COLEV) who did not give the date of the most recent procedure or who selected years ago in the time period format, COLLESTY reports the grouped year estimate of the number of years since the respondent's last colonoscopy.
The survey form directed interviewers to, "Read answer categories."
See Survey Text and Codes tabs.
