Although heated tobacco products (HTPs) have become popular worldwide, research on occupational differences in smoking HTPs remains scarce. We aimed to examine the prevalence of smoking HTPs among a working population in Japan.
SETTING, DESIGN AND PARTICIPANTS: In 2018, we conducted a cross-sectional study comprised of 7714 retail business workers in the service industry in Japan.
For the definition of smoking HTPs, we identified current HTP smokers who only smoked HTPs, using five mutual categories of current smoking status (never, former, HTPs only, combustible cigarettes only and dual smokers who smoked both combustible cigarettes and HTPs). Occupational classes were classified into office workers (eg, upper non-manual workers) and other workers. ORs and 95% CIs of office workers were estimated for HTP usage, adjusted for age, sex, employment type and cigarette smoking-related health knowledge.
The overall prevalence of smoking HTPs was 3.0% (male 5.0%, female 2.2%). The prevalence of HTP smokers differed across occupational classes (5.6% in office workers vs 2.5% in others; p<0.05). Compared with other workers, the adjusted odds of office workers for smoking HTPs remained elevated (OR: 1.97, 95% CI: 1.40 to 2.77). Sensitivity analyses with workers of all smoking status showed the same pattern. When stratified by sex, the occupational difference only remained significant in male workers.
We found a positive occupational difference in smoking HTPs, particularly among male workers in the retail sector in Japan. National tobacco control should explicitly address this occupational gap and further encourage individuals to quit smoking.
尽管加热烟草制品（HTP）在全球范围内越来越受欢迎，但有关吸烟 HTP 的职业差异的研究仍然很少。我们旨在研究日本工作人群中吸烟 HTP 的流行情况。
设置、设计和参与者：2018 年，我们进行了一项横断面研究，纳入了日本服务业的 7714 名零售业务工作者。
为了确定 HTP 的定义，我们将仅吸 HTP 的当前 HTP 吸烟者确定为当前 HTP 吸烟者，使用当前吸烟状态的五个相互类别（从不、以前、仅 HTP、仅可燃香烟和同时吸可燃香烟和 HTP 的双重吸烟者）。职业类别分为办公室工作人员（例如，非体力劳动者）和其他工作人员。调整了年龄、性别、就业类型和与吸烟有关的健康知识后，估计了办公室工作人员使用 HTP 的 OR 和 95%CI。
总体上，吸烟 HTP 的比例为 3.0%（男性 5.0%，女性 2.2%）。不同职业类别的 HTP 吸烟者比例存在差异（办公室工作人员为 5.6%，其他工作人员为 2.5%；p<0.05）。与其他工人相比，办公室工作人员吸烟 HTP 的调整后优势比仍然较高（OR：1.97，95%CI：1.40 至 2.77）。在包括所有吸烟状态的工人的敏感性分析中也显示出相同的模式。按性别分层时，这种职业差异仅在男性工人中仍然显著。
我们发现吸烟 HTP 存在明显的职业差异，尤其是在日本零售行业的男性工人中。国家烟草控制应明确解决这一职业差距，并进一步鼓励个人戒烟。
