To explore how and why tobacco smokers and recent quitters in NSW use e-cigarettes, as well as common places of purchase.
The Cancer Institute Tobacco Tracking Survey is a serial cross-sectional telephone survey, with 40 interviews in NSW each week.
2966 tobacco smokers and recent quitters (in the past 12 months) interviewed January 2014 - June 2015.
Current e-cigarette use; reasons for using; places of purchase.
9% of the sample reported currently using e-cigarettes; the rate was highest among 18-29-year-old people (16%). Infrequent use (less than weekly; 57%) was more common than frequent use (at least weekly; 43%). Frequent use was more likely among older adults (55 years and older v 18-29 years: adjusted odds ratio [aOR], 4.43; P = 0.002) and less likely among current tobacco smokers (v recent quitters: aOR, 0.38, P = 0.020). The most common reasons for using e-cigarettes by those over 30 years of age was "to help me quit" (42%) and to "cut down" smoking (35%); for younger adults it was "because they are not as bad for your health as cigarettes" (25%). Common places of purchase were the internet (29%) and tobacconists (27%).
Although use of e-cigarettes by tobacco smokers in NSW remains low, some are using e-cigarettes in attempts to reduce tobacco-related harm. Physicians and public health campaigners should inform smokers about the risks associated with dual e-cigarette and tobacco use, advise interested quitters that e-cigarettes are currently unregulated as cessation aids, and continue to provide evidence-based recommendations and cessation services to smokers wanting to quit.
探索新南威尔士州的吸烟者和近期戒烟者如何以及为何使用电子烟，以及常见的购买地点。
癌症研究所烟草追踪调查是一项连续的横断面电话调查，每周在新南威尔士州进行 40 次访谈。
2014 年 1 月至 2015 年 6 月期间接受采访的 2966 名吸烟者和近期戒烟者（过去 12 个月内）。
目前电子烟的使用情况；使用原因；购买地点。
样本中 9%的人报告目前正在使用电子烟；在 18-29 岁人群中的使用率最高（16%）。不频繁使用（每周不到一次；57%）比频繁使用（至少每周一次；43%）更为常见。在年龄较大的成年人中（55 岁及以上与 18-29 岁相比：调整后的优势比[aOR]，4.43；P = 0.002）更有可能经常使用电子烟，而在目前的吸烟者中（与近期戒烟者相比：aOR，0.38，P = 0.020）不太可能。30 岁以上人群使用电子烟的最常见原因是“帮助我戒烟”（42%）和“减少”吸烟（35%）；对于年轻成年人来说，“因为它们不像香烟那样对健康有害”（25%）。常见的购买地点是互联网（29%）和烟草店（27%）。
尽管新南威尔士州的吸烟者使用电子烟的比例仍然较低，但有些人正在使用电子烟以减少与烟草相关的危害。医生和公共卫生活动家应该告知吸烟者与双重使用电子烟和烟草相关的风险，建议有兴趣的戒烟者电子烟目前作为戒烟辅助工具不受监管，并继续为希望戒烟的吸烟者提供基于证据的建议和戒烟服务。
