We aimed to examine the use of heated tobacco products (HTPs) in locations where cigarette smoking was not allowed, and to explore the factors associated with such use among Japanese HTP users.
An internet-based self-reported questionnaire survey was conducted in 2019 as part of the Japan Society and New Tobacco Internet Survey. The study subjects were respondents who self-reported having used HTPs in the last year. The proportions of those who had ever used or frequently used HTPs in locations where tobacco smoking was not allowed in the last year were calculated. These locations included home, restaurants and workplaces. Furthermore, potential factors associated with HTP use in such smoke-free locations were examined using multivariable logistic regression analyses.
The proportion of HTP users who had ever used HTPs in smoke-free locations in the last year was 20.7% (148/716) at home, 11.8% (128/1081) in restaurants and 11.9% (113/950) in workplaces. The proportion of those who had frequently used HTPs in those locations was 9.5% (68/716) at home, 4.8% (52/1081) in restaurants and 8.0% (76/950) in workplaces. The statistically significant factors associated with HTP use varied by location. Generally, respondents who thought HTP use was not forbidden in places where tobacco smoking is forbidden were likely to use HTPs in such locations.
In Japan, a considerable number of people used HTPs in locations where tobacco smoking was not allowed. Policymakers should establish clear rules about use of HTPs in smoke-free environments.
我们旨在调查在禁止吸烟场所使用加热烟草制品（HTP）的情况，并探讨日本HTP使用者中与这种使用相关的因素。
作为日本社会与新烟草互联网调查的一部分，2019年进行了一项基于互联网的自我报告问卷调查。研究对象是那些自我报告在过去一年中使用过HTP的受访者。计算了去年在禁止吸烟场所曾经使用或经常使用HTP的人群比例。这些场所包括家庭、餐馆和工作场所。此外，使用多变量逻辑回归分析研究了在这些无烟场所使用HTP的潜在相关因素。
去年在无烟场所曾经使用过HTP的HTP使用者比例在家中为20.7%（148/716），在餐馆为11.8%（128/1081），在工作场所为11.9%（113/950）。在这些场所经常使用HTP的人群比例在家中为9.5%（68/716），在餐馆为4.8%（52/1081），在工作场所为8.0%（76/950）。与HTP使用相关的具有统计学意义的因素因场所而异。一般来说，认为在禁止吸烟的场所使用HTP不被禁止的受访者更有可能在这些场所使用HTP。
在日本，相当一部分人在禁止吸烟的场所使用HTP。政策制定者应制定关于在无烟环境中使用HTP的明确规则。
