OBJECTIVES
We assessed whether the prevalence of recent (within a year) initiation of cigarette smoking was associated with reports of ever using electronic delivery systems (ENDS) in the National Youth Tobacco Survey (NYTS) and whether the association varied by age.
METHODS
Weighted cross-sectional analysis of use of ENDS, cigarette smoking, age at interview and age at initiation of smoking collected systematically through the 2011-2013 NYTS cycles.
RESULTS
In multivariate analyses those who ever used ENDS were twice as likely as nonusers of ENDS to have tried cigarette smoking in the last year (multivariate PR: 2.3; 95 % CI 1.9, 2.7). This average hid significant variations by age: a 4.1-fold increase (95 %; 2.6, 6.4) among those 11-13 years of age, compared to a smaller increase among those 16-18 years: 1.4-fold (95 % CI 1.1, 1.8).
CONCLUSIONS
Use of ENDS by adolescents was associated with initiation of cigarette smoking in the last year. This association was stronger in younger adolescents.
目的
我们评估了在国家青少年烟草调查（NYTS）中，近期（一年内）开始吸烟的流行率是否与曾经使用过电子传递系统（ENDS）的报告相关，以及这种关联是否因年龄而异。
方法
对通过2011 - 2013年NYTS周期系统收集的ENDS使用情况、吸烟情况、访谈时年龄和开始吸烟时年龄进行加权横断面分析。
结果
在多变量分析中，曾经使用过ENDS的人在过去一年中尝试吸烟的可能性是非ENDS使用者的两倍（多变量PR：2.3；95% CI 1.9，2.7）。这一平均值掩盖了因年龄导致的显著差异：11 - 13岁人群中增加了4.1倍（95%；2.6，6.4），相比之下，16 - 18岁人群中增加幅度较小：1.4倍（95% CI 1.1，1.8）。
结论
青少年使用ENDS与过去一年开始吸烟有关。这种关联在较年轻的青少年中更强。
