INTRODUCTION
The prevalence of adolescent electronic cigarette (e-cigarette) use has increased in most countries. This study aims to determine the relation between the frequency of e-cigarette use and the frequency and intensity of cigarette smoking. Additionally, the study evaluates the association between the reasons for e-cigarette use and the frequency of its use.
MATERIALS AND METHODS
Using the 2015 Korean Youth Risk Behavior Web-Based Survey, we included 6655 adolescents with an experience of e-cigarette use who were middle and high school students aged 13-18 years. We compared smoking experience, the frequency and intensity of cigarette smoking, and the relation between the reasons for e-cigarette uses and the frequency of e-cigarette use.
RESULTS
The prevalence of e-cigarette ever and current (past 30 days) users were 10.1% and 3.9%, respectively. Of the ever users, approximately 60% used e-cigarettes not within 1 month. On the other hand, 8.1% used e-cigarettes daily. The frequent and intensive cigarette smoking was associated with frequent e-cigarette uses. The percentage of frequent e-cigarette users (≥10 days/month) was 3.5% in adolescents who did not smoke within a month, but 28.7% among daily smokers. Additionally, it was 9.1% in smokers who smoked less than 1 cigarette/month, but 55.1% in smokers who smoked ≥20 cigarettes/day. The most common reason for e-cigarette use was curiosity (22.9%), followed by the belief that they are less harmful than conventional cigarettes (18.9%), the desire to quit smoking (13.1%), and the capacity for indoor use (10.7%). Curiosity was the most common reason among less frequent e-cigarette users; however, the desire to quit smoking and the capacity for indoor use were the most common reasons among more frequent users.
CONCLUSIONS
Results showed a positive relation between frequency or intensity of conventional cigarette smoking and the frequency of e-cigarette use among Korean adolescents, and frequency of e-cigarette use differed according to the reason for the use of e-cigarettes.
引言
在大多数国家，青少年使用电子烟的比例有所上升。本研究旨在确定电子烟使用频率与吸烟频率及强度之间的关系。此外，该研究还评估了使用电子烟的原因与其使用频率之间的关联。
材料与方法
利用2015年韩国青少年风险行为网络调查，我们纳入了6655名有电子烟使用经历的青少年，他们为13至18岁的初高中学生。我们比较了吸烟经历、吸烟频率和强度，以及使用电子烟的原因与电子烟使用频率之间的关系。
结果
曾经使用过电子烟和当前（过去30天）使用过电子烟的比例分别为10.1%和3.9%。在曾经使用过电子烟的人群中，约60%的人使用电子烟的时间间隔超过1个月。另一方面，8.1%的人每天使用电子烟。频繁且大量吸烟与频繁使用电子烟有关。在一个月内不吸烟的青少年中，频繁使用电子烟（每月≥10天）的比例为3.5%，但在每日吸烟者中这一比例为28.7%。此外，每月吸烟少于1支的吸烟者中这一比例为9.1%，而每天吸烟≥20支的吸烟者中这一比例为55.1%。使用电子烟最常见的原因是好奇（22.9%），其次是认为其危害小于传统香烟（18.9%）、戒烟意愿（13.1%）以及可在室内使用（10.7%）。好奇是较少频繁使用电子烟者最常见的原因；然而，戒烟意愿和可在室内使用是较多频繁使用电子烟者最常见的原因。
结论
结果显示，在韩国青少年中，传统吸烟的频率或强度与电子烟使用频率呈正相关，且电子烟使用频率因使用原因而异。
