Codes and Frequencies
For sample adults aged 40 and older who ever had a colonoscopy (COLEV), COLLDMO reports the calender month of the respondent's most recent colonoscopy. This variable should be used together with COLLDYR, which reports the year of most recent colonoscopy.
The survey document directed interviewers to, "Enter month of last exam," and "Enter '96' to go to number and time period format."
For more information, please see COLEV.
