Despite an evolving e-cigarette environment, few studies have looked at adolescent exposure to e-cigarette advertising over time and its associations with curiosity about and susceptibility to using e-cigarettes. We examined e-cigarette advertising exposure and its associations with curiosity and susceptibility across multiple years among adolescents who have never used e-cigarettes.
We obtained data from the National Youth Tobacco Surveys (NYTSs), 2014-2020 (N = 97,496). The NYTS identified e-cigarette advertising exposure from four channels: Internet, newspapers and magazines, convenience stores, and TV. Logistic regressions explored e-cigarette advertising exposure over time and the associations between exposure from the four channels and both curiosity and susceptibility to using e-cigarettes.
Youth exposure to e-cigarette advertising on the Internet and in convenience stores formed an increase-decrease-increase pattern from 2014 to 2020, whereas exposure in newspapers and magazines and on TV generally decreased over this period. Exposure on the Internet and in convenience stores was consistently associated with curiosity and susceptibility; but exposure in newspapers and magazines and on TV was sporadically associated with the outcomes.
Despite a changing e-cigarette marketplace, youth were consistently exposed to e-cigarette advertising, especially on the Internet and in convenience stores. This pattern is worrisome, as it may increase youth curiosity and susceptibility to using e-cigarettes. Comprehensive tobacco prevention efforts to prevent e-cigarette use in adolescents should continue to restrict e-cigarette advertising and marketing, thereby reducing exposure and discouraging e-cigarette use. Regular efforts should also be made to educate adolescents about the risks of using e-cigarettes to counteract the impact of high e-cigarette advertising exposure.
尽管电子烟环境在不断发展，但很少有研究关注青少年随着时间的推移对电子烟广告的接触情况及其与对电子烟的好奇心和易感性的关系。我们研究了从未使用过电子烟的青少年在多年内接触电子烟广告及其与好奇心和易感性的关系。
我们从 2014 年至 2020 年的全国青少年烟草调查（NYTS）中获取数据（N=97496）。NYTS 从四个渠道识别电子烟广告的接触情况：互联网、报纸和杂志、便利店和电视。逻辑回归探讨了随着时间的推移电子烟广告的接触情况，以及四个渠道的接触情况与对电子烟的好奇心和易感性之间的关系。
青少年在互联网和便利店接触电子烟广告的情况从 2014 年到 2020 年呈增加-减少-增加的模式，而在报纸和杂志以及电视上的接触情况在此期间普遍下降。互联网和便利店的接触与好奇心和易感性相关；而报纸和杂志以及电视上的接触则与结果呈零星相关。
尽管电子烟市场在不断变化，但青少年始终接触到电子烟广告，尤其是在互联网和便利店。这种模式令人担忧，因为它可能会增加青少年对电子烟的好奇心和易感性。为预防青少年使用电子烟，全面的烟草预防工作应继续限制电子烟广告和营销，从而减少接触并阻止电子烟的使用。还应定期努力教育青少年电子烟使用的风险，以抵消电子烟高广告接触的影响。
