Collection and usage attributes

Guide for use:Help on this term

In order to estimate time since quitting for all respondents, the person's date of birth or current age should also be collected.

For optimal flexibility of use, the time since quitting is coded as months or years. However, people may report the time that they quit smoking in various ways (e.g. age, a date, or a number of days or weeks ago). When the information is reported in weeks and is less than 4, or in days and is less than 28, then code 80.

When the person reports the time since quitting as weeks ago, convert into months by dividing by 4 (rounded down to the nearest month).

If days reported are between 28 and 59, then code 81.

Where the information is about age only, time since quitting (daily use) is the difference between quit-age and age at survey.

Collection methods:Help on this term

The recommended standard for collecting this information is the Standard Questions on the Use of Tobacco Among Adults (1998) - interviewer administered (Question 6) and self-administered (Question 3) versions.

Comments:Help on this term

Time since quitting daily smoking may give an indication of improvement in the health risk profile of a person. It is also useful in evaluating health promotion campaigns.

Where this information is collected by survey and the sample permits, population estimates should be presented by sex and 5-year age groups. Summary statistics may need to be adjusted for age and other relevant variables.

It is recommended that in surveys of smoking, data on age, sex and other socio-demographic variables should be collected. It is also recommended that when smoking is investigated in relation to health, data on other risk factors including pregnancy status, physical activity, overweight and obesity, and alcohol consumption should be collected.
