摘要

Objectives

E-cigarettes have become increasingly popular worldwide in the last decade. This study examines secular trends and factors associated with self-reported e-cigarette use among the general population and youth across ten Canadian provinces.

Methods

This study used data from the 2015 and 2017 Canadian Tobacco, Alcohol, and Drugs Surveys and the 2019–2021 Canadian Tobacco and Nicotine Survey from Statistics Canada. The primary outcomes included self-reported ever, current, and high-frequency e-cigarette use. Weighted multivariate logistic regressions were applied to assess the association between the prevalence of self-reported e-cigarette use and gender, age, cigarette, province, and survey year. Crude and model-estimated provincial prevalence were reported and spatially mapped.

Results

Between 2015 and 2021, self-reported ever, current, and high-frequency e-cigarette use increased by 3.71%, 2.01%, and 2.92%, respectively. In 2021, the proportion of ever-users was lowest in Ontario and highest in Saskatchewan. New Brunswick showed the highest prevalence of current and high-frequency users, while British Columbia and Saskatchewan reported the lowest. Current smokers 35 years and older were more likely to have ever used e-cigarettes than teenage smokers (P < 0.001). Adolescents were significantly more likely to use e-cigarettes than adults (P < 0.001). Females were less likely to be ever or high-frequency users than males (P < 0.05).

Conclusion

This national and provincial analysis provides insights into e-cigarette use in Canada. Public health policies on e-cigarette use may benefit from considering jurisdictional and demographic differences, particularly in relation to use in public spaces.
