目的：电子烟的使用在美国迅速增加，尤其是在青少年中。大量青少年同时使用香烟和电子烟，通常称为双重使用。考虑到两种产品的使用频率，我们采用了新的双重用途分类。此外，我们还研究了双重使用与醒来后第一次吸烟的时间（尼古丁依赖测量）和戒烟意愿之间的关联。方法：数据来自 2015-2018 年全国青少年烟草调查。我们根据双重使用频率对参与者进行分组。使用多变量逻辑回归来检查双重使用频率与尼古丁依赖和戒烟意愿的关联。结果：不同类别的双重使用者在人口特征以及对吸烟和电子烟使用危害的信念方面存在差异。与仅吸烟者相比，高频电子烟双重使用者（醒来后5分钟内，比值比[OR]：1.67，95％置信区间[CI]，1.07-2.62；30分钟内，OR：1.61，95％CI，1.15-2.27）、高频香烟双重使用者（5分钟内，或： 2.85，95% CI，1.76-4.63； 30 分钟内，OR：4.14，95% CI，2.96-5.80），以及高频双用户（5 分钟，OR：4.46，95% CI，2.88-6.91；30 分钟，OR：3.94，95% CI，2.43-6.42）。此外，与仅吸烟者和低频双重使用者相比，高频电子烟双重使用者的戒烟意愿显着较低。结论：研究结果强调需要对双重使用者进行标准、精细的分类，因为不同类别之间的重要特征可能有所不同。未来关于双重用途的研究应考虑将双重用途分为本研究中描述的四种类别。 (C) 2019 年青少年健康与医学协会。版权所有。
Purpose: Electronic cigarettes (e-cigarette) use is rapidly increasing in the U.S., especially among adolescents. A significant number of adolescents use both cigarettes and e-cigarettes, often referred to as dual use. We used a new classification of dual use, taking into account the frequency of use of both products. In addition, we examined the association between dual use with time to first cigarette after waking (a nicotine dependence measure) and quit intention.Methods: Data were drawn from the 2015-2018 National Youth Tobacco Survey. We grouped participants by dual use frequency. Multivariable logistic regression was used to examine the association of dual use frequency with nicotine dependence and quit intention.Results: Different categories of dual users varied in demographic characteristics and beliefs on the harms of cigarette smoking and e-cigarette use. Compared with cigarette-only smokers, significantly higher odds of nicotine dependence were found for high-frequency e-cigarette dual users (within 5 minutes of awakening, odds ratio [OR]: 1.67, 95% confidence interval [CI], 1.07-2.62; within 30 minutes, OR: 1.61, 95% CI, 1.15-2.27), high-frequency cigarette dual users (5 minutes, OR: 2.85, 95% CI, 1.76-4.63; within 30 minutes, OR: 4.14, 95% CI, 2.96-5.80), and high-frequency dual users (5 minutes, OR: 4.46, 95% CI, 2.88-6.91; 30 minutes, OR: 3.94, 95% CI, 2.43-6.42). In addition, high-frequency e-cigarette dual users had significantly lower quit intention compared with both cigarette-only smokers and low-frequency dual users.Conclusions: Findings highlight the need for a standard, granulated classification of dual user, as important characteristics may vary between different categories. Future studies on dual use should consider categorizing dual use into the four classifications described in this study. (C) 2019 Society for Adolescent Health and Medicine. All rights reserved.
