Electronic cigarette use among survivors of smoking-related cancers in the United States
Menée aux Etats-Unis à partir de données d'enquêtes auprès de 3 162 patients ayant survécu à un cancer lié au tabac, cette étude analyse la prévalence de l'utilisation de la cigarette électronique et évalue son association avec des comportements tabagiques
Background: The prevalence of electronic cigarette (e-cigarette) use and its impact on smoking cessation among cancer survivors in the United States (US) is largely unknown. We sought to estimate the prevalence of e-cigarette use and examine its associations with cigarette smoking and smoking quit attempts among smoking-related cancer survivors in the US.
Methods: We obtained data from the 2014-2017 annual cycles of the National Health Interview Survey for participants with self-reported history of smoking-related cancer(s). We calculated the prevalence of current e-cigarette use and utilized multinomial logistic regression in examining the independent association between e-cigarette use and cigarette smoking. Appropriate survey weights were applied in estimating the prevalence rates, relative risk ratios (RRR), odds ratios (OR), and confidence intervals (CI).
Results: Our sample comprised 3,162 survivors. The prevalence of current e-cigarette use was 3.18% (95% CI: 2.40%-3.96%). Current e-cigarette users were eighty-three times as likely as never users to be current cigarette smokers (RRR: 82.89; 95% CI: 16.54-415.37). Among those with a history of cigarette smoking, current e-cigarette users were 90% less likely to be former smokers (OR: 0.10; 95% CI: 0.05-0.18). No association was seen between current e-cigarette use and a smoking quit attempt in the prior year.
Conclusion: E-cigarette use among cigarette ever-smokers was associated with a lower likelihood of being a former smoker/having quit smoking; and e-cigarette use was not associated with smoking quit attempts.
Impact: Our findings do not provide evidence that e-cigarette use facilitates smoking cessation among smoking-related cancer survivors.
