  • *Estimates are weighted to produce population estimates using pooled sampling weights provided by Statistics Canada.

  • †Model 2 adjustments include age, sex, survey cycle, urban/rural designation, household income quintile, racialisation and immigrant status.

  • ‡Model 3 adjustments include all model two covariates plus smoking behaviour, alcohol consumption, physical activity and body mass index. Models for the older two age groups (36–55 years and 56–70 years) additionally adjust for diagnosis of chronic obstructive pulmonary disease/emphysema, cancer, diabetes or heart disease.
