The present study aimed to examine the experience of actual electronic cigarette (e-cigarette) use in smoke-free areas of restaurants and workplaces and to explore the determinants associated with such use among Japanese adults who reported any experience using e-cigarettes (e-cigarette ever-users).
An Internet-based self-reported questionnaire survey was conducted in 2015 on Japanese e-cigarette ever-users. The proportion of the respondents who had ever used or frequently used e-cigarettes in smoke-free restaurants and/or workplaces was calculated. Potential factors associated with e-cigarette use in those smoke-free areas were also examined by using multivariable logistic regression analyses.
In total, 1243 e-cigarette ever-users (662 current and 581 former e-cigarette users) were analysed. The majority of them (1020/1243, 82.1%) were male and their mean age ± SD was 47.0±10.4 years. The proportion of those who had ever used e-cigarettes in smoke-free restaurants was 28.8% (358/1243) and that in smoke-free workplaces was 25.5% (317/1243), respectively. The proportion of those who had frequently used e-cigarettes in smoke-free restaurants was 18.5% (230/1243) and that in smoke-free workplaces was 16.3% (202/1243), respectively. In general, the proportion of e-cigarette use in those smoke-free areas was higher among those having a higher educational level than those having a lower educational level.
Among adult Japanese e-cigarette ever-users, approximately 26%-29% had ever used and 16%-19% had frequently used e-cigarettes in restaurants and/or workplaces where combustible tobacco smoking is not allowed. Policy-makers may need to establish explicit rules as to e-cigarette use in smoke-free environments.
本研究旨在调查在餐厅和工作场所无烟区实际使用电子烟（电子烟）的体验，并探索在报告使用电子烟（电子烟曾使用者）的日本成年人中，与这种使用相关的决定因素。
2015 年，对日本电子烟曾使用者进行了基于互联网的自我报告问卷调查。计算了在无烟餐厅和/或工作场所曾使用或经常使用电子烟的受访者比例。还通过多变量逻辑回归分析检查了与这些无烟区电子烟使用相关的潜在因素。
共有 1243 名电子烟曾使用者（662 名当前电子烟使用者和 581 名前电子烟使用者）进行了分析。他们中的大多数（1020/1243，82.1%）为男性，平均年龄±标准差为 47.0±10.4 岁。曾在无烟餐厅使用电子烟的比例为 28.8%（358/1243），在无烟工作场所使用电子烟的比例为 25.5%（317/1243）。曾在无烟餐厅频繁使用电子烟的比例为 18.5%（230/1243），在无烟工作场所频繁使用电子烟的比例为 16.3%（202/1243）。一般来说，在那些教育程度较高的人群中，在无烟区使用电子烟的比例高于那些教育程度较低的人群。
在日本成年电子烟曾使用者中，大约有 26%-29%曾在不允许吸食可燃烟草的餐厅和/或工作场所使用电子烟，16%-19%曾在这些场所频繁使用电子烟。决策者可能需要制定明确的规则，以规范在无烟环境中使用电子烟。
