Abstract

Objective

E-cigarette use is associated with subsequent cigarette smoking among youth. The current study examined the mediating role of social-cognitive factors in this association.

Methods

Data from four waves of the Population Assessment of Tobacco and Health study (2013/4 – 2017/8) were analyzed. Among youth who had heard about e-cigarettes at Wave 1 but never used cigarettes before Wave 2, we conducted both causal and traditional mediation analyses to examine the mediated effect of social-cognitive factors (including relative harm perception of e-cigarettes versus cigarettes, harm perception of e-cigarette use, perceptions of addictiveness of e-cigarette use, and e-cigarette use among best friends) in the association between e-cigarette use and subsequent cigarette ever or current smoking, adjusting for covariates. We included sampling weights in all analyses; hence, results are generalizable to the U.S. youth (12 – 14 years) from the 2013–2014 cohort.

Results

Results from causal mediation analyses indicated that the total effect of e-cigarette use, compared to no use, increased the risk of cigarette ever smoking (20.9 %) and current smoking (4.6 %). A portion of this effect (4.2 % − 15.1 % for ever smoking; less than 10.6 % for current smoking) can be attributed to changes in social-cognitive factors induced by e-cigarette use. However, these mediated effects were small in magnitude relative to their standard errors and not statistically significant. Results from the traditional mediation analyses largely aligned with these findings, except for a few small sized pathways.

Conclusions

For the U.S. youth population, social-cognitive factors may only minimally or not at all mediate the association between e-cigarette use and subsequent cigarette smoking. Further investigation into the mediation role of social-cognitive factors is warranted. Tobacco control interventions that focus on cigarette smoking initiation among youth should target other mediating factors.

社会认知因素在美国青少年使用电子烟与随后吸烟之间关系中的作用：因果中介分析

目的：青少年使用电子烟与随后吸烟有关。本研究探讨了社会认知因素在这一关联中的中介作用：分析了四波烟草与健康人群评估研究（2013/4 - 2017/8）的数据。在第1波听说过电子烟但在第2波之前从未使用过香烟的青少年中，我们进行了因果分析和传统中介分析，以考察社会认知因素（包括对电子烟与香烟相对危害的认知、对电子烟使用危害的认知、对电子烟使用成瘾性的认知以及最好的朋友中使用电子烟的情况）在电子烟使用与随后的曾经吸烟或当前吸烟之间的关联中的中介作用，并对协变量进行了调整。我们在所有分析中都加入了抽样权重；因此，分析结果可推广至2013-2014年队列中的美国青少年（12-14岁）：因果中介分析结果表明，与不使用电子烟相比，使用电子烟的总效应增加了曾经吸烟（20.9%）和目前吸烟（4.6%）的风险。这种影响的一部分（4.2% - 15.1%（曾经吸烟）；不到 10.6%（目前吸烟））可归因于使用电子烟引起的社会认知因素的变化。然而，这些中介效应的幅度相对于其标准误差较小，在统计学上也不显著。传统中介分析的结果与这些发现基本一致，只有少数小规模的途径除外：结论：对于美国青少年群体来说，社会认知因素对电子烟使用与后续吸烟之间的关联可能只起了很小的中介作用，甚至根本不起中介作用。有必要进一步调查社会认知因素的中介作用。针对青少年开始吸烟的烟草控制干预措施应针对其他中介因素。

期刊介绍： Addictive Behaviors is an international peer-reviewed journal publishing high quality human research on addictive behaviors and disorders since 1975. The journal accepts submissions of full-length papers and short communications on substance-related addictions such as the abuse of alcohol, drugs and nicotine, and behavioral addictions involving gambling and technology. We primarily publish behavioral and psychosocial research but our articles span the fields of psychology, sociology, psychiatry, epidemiology, social policy, medicine, pharmacology and neuroscience. While theoretical orientations are diverse, the emphasis of the journal is primarily empirical. That is, sound experimental design combined with valid, reliable assessment and evaluation procedures are a requisite for acceptance. However, innovative and empirically oriented case studies that might encourage new lines of inquiry are accepted as well. Studies that clearly contribute to current knowledge of etiology, prevention, social policy or treatment are given priority. Scholarly commentaries on topical issues, systematic reviews, and mini reviews are encouraged. We especially welcome multimedia papers that incorporate video or audio components to better display methodology or findings. Studies can also be submitted to Addictive Behaviors? companion title, the open access journal Addictive Behaviors Reports, which has a particular interest in ''non-traditional'', innovative and empirically-oriented research such as negative/null data papers, replication studies, case reports on novel treatments, and cross-cultural research.
