Percentage of individuals (aged ≥ 12) reporting daily or occasional smoking, by cancer status and sex, Canada, age-standardized to the 2011 Canadian population — 2011–14 reporting years combined
Definition: Percentage of current cancer patients aged 12 years and older reporting daily or occasional smoking compared to the non-cancer patient population if the age distribution in the populations of interest were the same as that of the standard
Numerator:
Number of daily or occasional smokers who are current cancer patients;
Number of daily or occasional smokers who are in the non-cancer patient population
Denominator:
Total number of current cancer patients aged 12 years and older;
Total number of individuals in the non-cancer patient population aged 12 years and older
Data source: Statistics Canada, Canadian Community Health Survey (CCHS)
Measurement timeframe: 2011-2014 combined
CCHS variables:
In your lifetime, have you smoked a total of 100 or more cigarettes (about 4 packs)?
Have you ever smoked a whole cigarette?
At the present time, do you smoke cigarettes daily, occasionally or not at all?
Have you ever smoked cigarettes daily?
Do you have cancer?
Stratification variables: Cancer status (current cancer patients, non-cancer patient population), sex
Provinces/territories with data available: All provinces/territories
Notes:
Smoking prevalence by cancer status was age standardized to the 2011 Canadian population to account for the age distribution differences between the current cancer patient population and the non-cancer patient population.
Current cancer patients are defined as those who answered yes to the ‘Do you have cancer?’ question. Those who answered no are defined as the non-cancer patient population.
CCHS data are based on a representative sample which is then extrapolated to the overall population.
