The use of e-cigarettes has become more common in China, but the research on e-cigarettes in China, while growing, is still limited. This study examined the characteristics and patterns of e-cigarette use, and analyzed the possible mediators between cigarette cessation intention and e-cigarette use in a Chinese smoking population.
This was a cross-sectional study conducted in mainland China. By convenience sampling method, the participants were recruited from 85 major commercial streets of several large cities in China. The study interviewers completed face-to-face interviews and uploaded the completed questionnaires into the online survey platform. The participants were contacted for clarification if any problems were detected. Logistic regression yielded adjusted odds ratios (ORs) for ever use of e-cigarettes. We further conducted a mediation analysis to estimate the effect of possible mediators.
From July to August 2020, a total of 738 smokers were invited to participate in this study; 613 smokers were identified as eligible and 609 smokers were included in this analysis. Of them, 24 (3.94%) participants were currently using e-cigarettes, and 165 (27.09%) participants have ever used e-cigarettes. The participants with younger age were more likely to have ever used e-cigarettes, ranging from 37.5% in the 18-29 years age group to 6.5% in the 60-69 years age group. After controlling for demographic characteristics and nicotine dependence, the ever use of e-cigarettes was significantly associated with younger age, higher education level, higher monthly income, previous smoking cessation attempts and quitting intention. With the mediation analysis, the education level is confirmed as a mediating factor, and approximately 42.86% of the effects were mediated through the channel of higher socioeconomic status.
This is the first study to examine the possible mediators between cigarette cessation intention and e-cigarette use in a Chinese smoking population. The findings revealed that high socioeconomic status, particularly higher education level, was a major mediating factor.
电子烟在中国的使用日益普遍，但中国对电子烟的研究虽在增加，仍较为有限。本研究调查了电子烟使用的特征和模式，并分析了中国吸烟人群中戒烟意愿与电子烟使用之间可能的中介因素。
这是一项在中国内地开展的横断面研究。采用便利抽样法，从中国几个大城市的85条主要商业街道招募参与者。研究访谈员完成面对面访谈，并将填好的问卷上传至在线调查平台。若发现任何问题，会与参与者联系以进行澄清。逻辑回归得出曾经使用电子烟的调整比值比（OR）。我们进一步进行中介分析以估计可能中介因素的作用。
2020年7月至8月，共邀请73名吸烟者参与本研究；613名吸烟者符合条件，609名吸烟者纳入本分析。其中，24名（3.94%）参与者目前正在使用电子烟，165名（27.09%）参与者曾经使用过电子烟。年龄较小的参与者更有可能曾经使用过电子烟，在18 - 29岁年龄组中为37.5%，在60 - 69岁年龄组中为6.5%。在控制人口统计学特征和尼古丁依赖后，曾经使用电子烟与年龄较小、教育水平较高、月收入较高、既往戒烟尝试和戒烟意愿显著相关。通过中介分析，教育水平被确认为一个中介因素，约42.86%的影响通过较高社会经济地位这一途径介导。
这是第一项研究中国吸烟人群中戒烟意愿与电子烟使用之间可能中介因素的研究。研究结果显示，较高的社会经济地位，尤其是较高的教育水平，是一个主要的中介因素。
