Smoking status at baseline is measured with smoking-related data gathered at the baseline interview. Current and former smoking habits are assessed using the following questions:
Question 1 is used to determine current smokers, and question 2 identifies previous smokers. Participants who answer "no" to both questions are categorized as "never smoked" (see below).
Value | Response |
---|---|
0 | Never smoked |
1 | Former smoker (does not currently smoke) |
2 | Current smoker |
Note: Categories are mutually exclusive.
