Electronic Cigarette Use among Survivors of Smoking-Related Cancers in the United States
Menée aux Etats-Unis auprès de 3 162 personnes ayant survécu à un cancer lié au tabac (âge : au moins 18 ans ; 58% de femmes), cette étude analyse leur utilisation de la cigarette électronique et son impact sur leur sevrage tabagique
Background : The prevalence of electronic cigarette (e-cigarette) use and its impact on smoking cessation among cancer survivors in the United States 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 United States. 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), ORs, and confidence intervals (CI). Results : Our sample comprised 3,162 smoking-related cancer survivors. The prevalence of current e-cigarette use was 3.18% (95% CI, 2.40–3.96). Current e-cigarette users were 83 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. Conclusions : 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.
