Term: "Ever Smoked" Category
Last Updated: 2015-05-12
In
Martens et al. (2015),
survey data from a series of questions about lifetime smoking habits (up to time of survey) were used to classify respondents from all surveys as either "ever smoked" or "never smoked" at time of survey. Due to differences between surveys, different questions were utilized to categorize respondents into the ever smoked cohort.
For more information on how this was derived from each different survey, please see the
"Ever Smoked" Category
term and description in the glossary of Martens et al. (2015).
