背景资料：公众对电子尼古丁输送系统（ENDS）的兴趣没有记录。目的：通过监测搜索查询，在澳大利亚、加拿大、英国（UK）和美国评估了ENDS的流行程度及其流行程度的相关性。方法：从2008年1月到2010年9月进行的英语谷歌搜索与鼻烟，尼古丁替代疗法（NRT），和Chantix（R）或Chantix（R）。每周的搜索比例被缩放到最高的每周搜索比例（100），较低的值表示与最高比例周相比的相对搜索比例（e。例如，在一个实施例中，50=最高观测比例的50%）。结果：从2008年7月到2010年2月，除澳大利亚外，所有研究国家的ENDS检索都有所增加，最近才有所增加。到2010年9月，在英国和美国，ENDS搜索量是吸烟替代品搜索量的几百倍，并与澳大利亚和加拿大的替代品竞争。在所有国家中，美国的ENDS搜索量最高，其次是加拿大和英国，澳大利亚的ENDS搜索次数最少。更强有力的烟草控制，创造了清洁的室内空气法，卷烟税，和反吸烟人群，与持续较高水平的ENDS searchs.Conclusions：ENDS的在线流行度已经超过了鼻烟和NRT，这已经在市场上更长的时间，并迅速超过Chantix或Chantix。在某种程度上，ENDS的受欢迎程度和更强的烟草控制之间的关联表明，ENDS被用来绕过或戒烟，以应对吸烟限制。搜索查询监测是一种有价值的，实时的，免费的，公共的方法来评估新的健康产品的扩散。这种方法可以推广到搜索引擎上表现出的其他行为，生物，信息或心理结果。(Am J Prev Med 2011;40（4）：448-453）（C）2011年美国预防医学杂志
Background: Public interest in electronic nicotine delivery systems (ENDS) is undocumented.Purpose: By monitoring search queries, ENDS popularity and correlates of their popularity were assessed in Australia, Canada, the United Kingdom (UK), and the U.S.Methods: English-language Google searches conducted from January 2008 through September 2010 were compared to snus, nicotine replacement therapy (NRT), and Chantix (R) or Champix (R). Searches for each week were scaled to the highest weekly search proportion (100), with lower values indicating the relative search proportion compared to the highest-proportion week (e. g., 50=50% of the highest observed proportion). Analyses were performed in 2010.Results: From July 2008 through February 2010, ENDS searches increased in all nations studied except Australia, there an increase occurred more recently. By September 2010, ENDS searches were several-hundred-fold greater than searches for smoking alternatives in the UK and U.S., and were rivaling alternatives in Australia and Canada. Across nations, ENDS searches were highest in the U.S., followed by similar search intensity in Canada and the UK, with Australia having the fewest ENDS searches. Stronger tobacco control, created by clean indoor air laws, cigarette taxes, and anti-smoking populations, were associated with consistently higher levels of ENDS searches.Conclusions: The online popularity of ENDS has surpassed that of snus and NRTs, which have been on the market for far longer, and is quickly outpacing Chantix or Champix. In part, the association between ENDS's popularity and stronger tobacco control suggests ENDS are used to bypass, or quit in response to, smoking restrictions. Search query surveillance is a valuable, real-time, free, and public method to evaluate the diffusion of new health products. This method may be generalized to other behavioral, biological, informational, or psychological outcomes manifested on search engines.
