The widespread popularity of e-cigarettes is considered an important public health concern. However, only some studies have investigated the prevalence of e-cigarette use in Shanghai, China. Research on the perceived harmfulness of e-cigarettes and public support for e-cigarette regulations in China is limited. This study aimed to estimate e-cigarette awareness, prevalence, and associated factors among adults in Shanghai, China.
This study used data from a representative survey conducted in Shanghai, China, in 2019. The survey was conducted at 64 surveillance points in Shanghai, China, using a multistage, stratified, cluster-randomized sampling design, recruiting community-based Chinese adults aged ≥15 years. Based on the principles outlined in the Global Adult Tobacco Survey (GATS) China Project, data were collected by conducting face-to-face interviews in households. Of the 3200 selected households, 3060 people completed the individual survey. The overall response rate was 97.4%.
In all, 72.3% of the respondents had heard of e-cigarettes. The respondents who had used e-cigarettes at some point in their life, used them in the last 12 months, and used them currently were 5.8%, 2.6%, and 1.3%, respectively. Among adult residents who had heard of e-cigarettes, 38.2% thought they were less harmful than traditional cigarettes. The respondents who perceived e-cigarettes as more harmful than traditional cigarettes were less likely to have ever used e-cigarettes (AOR=0.2; 95% CI: 0.1-0.5, p=0.0015) and more likely to support incorporating e-cigarettes into the regulation of smoking control (AOR=3.9; 95% CI: 1.8-8.6, p=0.0008).
Our findings reveal that the awareness about e-cigarettes was high, and the prevalence of e-cigarette use was similar to the findings from previous studies in China. The harmful perception of e-cigarettes warrants further attention from public health practitioners.
电子烟的广泛流行被视为一个重要的公共卫生问题。然而，仅有一些研究调查了中国上海电子烟的使用情况。关于电子烟的感知危害以及中国公众对电子烟监管的支持情况的研究较为有限。本研究旨在估计中国上海成年人中电子烟的知晓率、使用率及相关因素。
本研究使用了2019年在中国上海进行的一项代表性调查的数据。该调查在中国上海的64个监测点进行，采用多阶段、分层、整群随机抽样设计，招募年龄≥15岁的社区成年中国人。根据全球成人烟草调查（GATS）中国项目概述的原则，通过在家庭中进行面对面访谈收集数据。在3200个选定家庭中，3060人完成了个人调查。总体回应率为97.4%。
总计72.3%的受访者听说过电子烟。曾经使用过电子烟、在过去12个月内使用过电子烟以及目前正在使用电子烟的受访者分别占5.8%、2.6%和1.3%。在听说过电子烟的成年居民中，38.2%认为它们比传统香烟危害小。认为电子烟比传统香烟危害更大的受访者曾经使用过电子烟的可能性较小（比值比[AOR]=0.2；95%置信区间[CI]：0.1 - 0.5，p = 0.0015），且更有可能支持将电子烟纳入控烟监管（AOR = 3.9；95% CI：1.8 - 8.6，p = 0.0008）。
我们的研究结果显示，对电子烟的知晓率较高，电子烟的使用率与中国此前的研究结果相似。电子烟的危害认知值得公共卫生从业者进一步关注。
