| description | Measurement to ascertain the respondent's age of initiation of first/regular use of cigarettes, which can be used to calculate duration of use and pack-years measures. The PhenX Working Group modified the Adult Protocol to provide a more precise measure. The original wording of "fairly regularly" was changed to "every day." There are two questions in this protocol. Current Every-Day Smokers (based on responses to the Tobacco - Smoking Status [Adult Protocol]) are asked the age when they initiated smoking every day. Current Some-Day Smokers and Former Smokers (based on responses to the Tobacco - Smoking Status [Adult Protocol]) are asked the second question about the age when they initiated smoking fairly regularly. Participant's age in years is recorded. | ||
