引言：公众对电子尼古丁输送系统（ENDS）的看法仍然知之甚少，因为调查成本太高，无法定期实施，而且即使实施，数据收集和传播之间也有很长的延迟。搜索查询监控弥补了其中的一些缺陷。在这里，使用谷歌搜索重新评估ENDS在美国的受欢迎程度。方法：从2009年1月到2015年1月，在美国进行的ENDS搜索按电子烟（例如，e- cigg）和电子烟（例如，vapers）的关键词进行分类；他们的地理位置（例如，州）；与其地理位置相对应的综合烟草控制措施（例如，清洁室内空气法）；根据搜索者潜在兴趣的关键词（例如，购买电子烟可能意味着购物）——这些都是2015年的分析结果。结果：ENDS在美国的搜索量迅速增长，仅2014年就有849.8万次搜索。搜索词越来越多地从电子烟转向以电子烟为重点的词，尤其是在沿海州和反吸烟规范更强的州。例如，在全国范围内，2014年电子烟的搜索量比2013年下降了9% (95% CI = 1%, 16%)，而电子烟的搜索量增加了136% (95% CI = 97%, 186%)，甚至超过了电子烟的搜索量。此外，与购物（例如，电子烟商店）相关的终端搜索百分比在2014年几乎翻了一番，而与健康问题（例如，电子烟风险）或戒烟（例如，用电子烟戒烟）相关的搜索很少，并且在2014年有所下降。结论：ENDS的受欢迎程度正在迅速增长和发展。这些发现可以为后续调查的调查问卷编制提供信息，并立即指导有关公众如何看待ENDS的健康风险或戒烟益处的政策辩论。(C) 2016美国预防医学杂志。Elsevier Inc.出版。版权所有。
Introduction: Public perceptions of electronic nicotine delivery systems (ENDS) remain poorly understood because surveys are too costly to regularly implement and, when implemented, there are long delays between data collection and dissemination. Search query surveillance has bridged some of these gaps. Herein, ENDS' popularity in the U.S. is reassessed using Google searches.Methods: ENDS searches originating in the U.S. from January 2009 through January 2015 were disaggregated by terms focused on e-cigarette (e.g., e-cig) versus vaping (e.g., vapers); their geolocation (e.g., state); the aggregate tobacco control measures corresponding to their geolocation (e.g., clean indoor air laws); and by terms that indicated the searcher's potential interest (e.g., buy e-cigs likely indicates shopping)-all analyzed in 2015.Results: ENDS searches are rapidly increasing in the U.S., with 8,498,000 searches during 2014 alone. Increasingly, searches are shifting from e-cigarette-to vaping-focused terms, especially in coastal states and states where anti-smoking norms are stronger. For example, nationally, e-cigarette searches declined 9% (95% CI = 1%, 16%) during 2014 compared with 2013, whereas vaping searches increased 136% (95% CI = 97%, 186%), even surpassing e-cigarette searches. Additionally, the percentage of ENDS searches related to shopping (e.g., vape shop) nearly doubled in 2014, whereas searches related to health concerns (e.g., vaping risks) or cessation (e.g., quit smoking with e-cigs) were rare and declined in 2014.Conclusions: ENDS popularity is rapidly growing and evolving. These findings could inform survey questionnaire development for follow-up investigation and immediately guide policy debates about how the public perceives the health risks or cessation benefits of ENDS.
