电子烟（电子烟）的使用与年轻人开始吸烟有关；然而，吸烟也有可能与电子烟的开始有关。这项研究在英国的年轻人中探讨了这些联系。在2016年4月对1152名11至18岁的青少年进行了纵向调查，并于2016年8月至10月进行了随访。逻辑回归模型和因果中介分析评估了(1)基线从不吸烟者（n = 923）中曾经使用电子烟和升级是否与开始吸烟（随访时曾经吸烟）相关，以及(2)基线从不吸烟者（n = 1020）中曾经吸烟和升级是否与开始吸烟（随访时曾经使用电子烟）相关。在基线时，19.8%的人曾经吸烟，11.4%的人曾经吸过电子烟。曾经吸过电子烟的受访者（相对于从未吸过电子烟的受访者，53% vs. 8%，优势比[OR] = 11.89, 95%可信区间[CI] = 3.56-39.72）和升级电子烟使用的受访者（相对于没有吸过电子烟的受访者，41% vs. 8%, OR = 7.89, 95% CI = 3.06-20.38）更有可能开始吸烟。曾经吸烟者（相对于从不吸烟者，32%对4%，OR = 3.54, 95% CI = 1.68-7.45）和吸烟升级的受访者（相对于不吸烟者，34%对6%，OR = 5.79, 95% CI = 2.55-13.15）更有可能开始使用电子烟。曾经吸过电子烟对开始吸烟有直接影响（OR = 1.34, 95% CI = 1.05-1.72），曾经吸过电子烟对开始吸烟有直接影响（OR = 1.08, 95% CI = 1.01-1.17）；电子烟和吸烟增加分别没有调节这些影响。在英国的年轻人中，曾经使用电子烟与开始吸烟有关，而曾经吸烟与开始吸电子烟有关。
Electronic cigarette (e-cigarette) use is associated with smoking initiation among young people; however, it is also possible that smoking is associated with e-cigarette initiation. This study explores these associations among young people in Great Britain. A longitudinal survey of 1,152 11- to 18-year-olds was conducted with baseline in April 2016 and follow-up between August and October 2016. Logistic regression models and causal mediation analyses assessed whether (1) ever e-cigarette use and escalation were associated with smoking initiation (ever smoking at follow-up) among baseline never smokers (n = 923), and (2) ever smoking and escalation were associated with e-cigarette initiation (ever e-cigarette use at follow-up) among baseline never e-cigarette users (n = 1,020). At baseline, 19.8% were ever smokers and 11.4% were ever e-cigarette users. Respondents who were ever e-cigarette users (vs. never users, 53% vs. 8%, odds ratio [OR] = 11.89, 95% confidence interval [CI] = 3.56–39.72) and escalated their e-cigarette use (vs. did not, 41% vs. 8%, OR = 7.89, 95% CI = 3.06–20.38) were more likely to initiate smoking. Respondents who were ever smokers (vs. never smokers, 32% vs. 4%, OR = 3.54, 95% CI = 1.68–7.45) and escalated their smoking (vs. did not, 34% vs. 6%, OR = 5.79, 95% CI = 2.55–13.15) were more likely to initiate e-cigarette use. There was a direct effect of ever e-cigarette use on smoking initiation (OR = 1.34, 95% CI = 1.05–1.72), and ever smoking on e-cigarette initiation (OR = 1.08, 95% CI = 1.01–1.17); e-cigarette and smoking escalation, respectively, did not mediate these effects. Among young people in Great Britain, ever e-cigarette use is associated with smoking initiation, and ever smoking is associated with e-cigarette initiation.
