The goal of this study was to examine the prevalence and perceptions of electronic cigarette use among Canadian youth and young adults.
A sample of 1,188 youth and young adults age 16-30 years were recruited from an online panel of Canadians in 2012. After viewing an image of an e-cigarette, respondents answered questions regarding their use and perceptions of e-cigarettes.
Close to half of respondents (43.4%) had seen e-cigarettes advertised or for sale. A total of 16.1% reported trying an e-cigarette (5.2% nonsmokers, 18.9% former smokers, and 34.5% current smokers), and 5.7% reported use in the past 30 days (0.8% non-smokers, 1.4% former smokers, and 15.0% current smokers). Compared to non-smokers, former smokers and current smokers were more likely to have tried e-cigarettes (OR=4.25 and OR=9.84, respectively), and current smokers were more likely to have tried e-cigarettes than former smokers (OR=2.32). Current smokers were also more likely to be current users of e-cigarettes than both former smokers (OR=15.15) and non-smokers (OR=4.43). Smokers were interested in trying e-cigarettes to help them quit smoking (80.4%), as a long-term replacement for cigarettes (77.8%), or to use in places where they cannot smoke (80.9%).
Awareness of e-cigarettes among surveyed youth and young adults is quite high. Almost one fifth (16.1%) of participants reported trying e-cigarettes, with evidence of use among non-smokers.
本研究旨在调查加拿大青少年和青年中电子烟的使用情况及认知。
2012年从加拿大在线小组中招募了1188名16 - 30岁的青少年和青年。在观看电子烟图片后,受访者回答了关于他们对电子烟的使用及认知的问题。
近一半的受访者(43.4%)见过电子烟广告或有售卖。共有16.1%的受访者报告尝试过电子烟(5.2%为非吸烟者,18.9%为曾经吸烟者,34.5%为当前吸烟者),5.7%的受访者报告在过去30天内使用过电子烟(0.8%为非吸烟者,1.4%为曾经吸烟者,15.0%为当前吸烟者)。与非吸烟者相比,曾经吸烟者和当前吸烟者尝试电子烟的可能性更高(分别为OR = 4.25和OR = 9.84),且当前吸烟者尝试电子烟的可能性高于曾经吸烟者(OR = 2.32)。当前吸烟者作为电子烟当前使用者的可能性也高于曾经吸烟者(OR = 15.15)和非吸烟者(OR = 4.43)。吸烟者对尝试电子烟感兴趣的原因包括帮助戒烟(80.4%)、作为香烟的长期替代品(77.8%)或在禁止吸烟的场所使用(80.9%)。
在接受调查的青少年和青年中,电子烟的知晓率相当高。近五分之一(16.1%)的参与者报告尝试过电子烟,且有非吸烟者使用电子烟的证据。
