BACKGROUND
For novel tobacco products that potentially reduce the risk of tobacco harm, post-market surveillance is important to observe population usage and behaviours associated with everyday use. This pilot study was performed to examine the use of tobacco products in three Japanese urban regions.
METHODS
This study was a cross-sectional epidemiological survey administered in Sendai, Tokyo and Osaka, Japan, from May 19th to June 25th, 2018. Participants were selected with a three-stage probability random sampling process that first identified primary sampling units, then households and finally individuals. Eligible participants were aged at least 20 years who were willing to participate after information about the study was provided. People younger than 20 years and those living in institutions were excluded. Questionnaires were paper based and administered door to door.
RESULTS
Responses were obtained from 4154 participants. Sixty-five percent self-reported being never, 19% current and 16% former users of any tobacco product at the time of the survey. Combustible tobacco products (almost all being cigarette) were used most (16%) followed by HTPs (5%). In the categories of combustible tobacco users and HTP users, 70% and 16%, respectively, used these products exclusively. Dual use was reported by 11% of respondents. Compared with 12 months before the survey, 12% of sole combustible tobacco products users were using HTPs exclusively or as dual users and 6% had quit tobacco products completely; 94% of sole HTP users remained sole users and 4% had quit tobacco products completely; and amongst dual users 12% had reverted to exclusive use of combustible tobacco products, 14% had switched to sole use of HTPs and 4% had quit tobacco products completely.
CONCLUSION
HTPs seem to be accepted as an alternative tobacco product amongst combustible tobacco users. Given complex findings for dual use, improved understanding of the motivations underlying this behaviour would be of interest.
背景
对于潜在降低烟草危害风险的新型烟草产品，上市后监测对于观察与日常使用相关的人群使用和行为非常重要。本研究旨在检测日本三个城市地区的烟草制品使用情况。
方法
本研究是一项于 2018 年 5 月 19 日至 6 月 25 日在日本仙台、东京和大阪进行的横断面流行病学调查。采用三阶段概率随机抽样过程选择参与者，首先确定初级抽样单位，然后是家庭，最后是个人。符合条件的参与者年龄至少 20 岁，在提供有关研究的信息后愿意参加。20 岁以下的人和居住在机构中的人被排除在外。问卷采用纸质形式，逐户上门进行管理。
结果
共获得 4154 名参与者的回复。65%的人报告在调查时从未使用过任何烟草制品，19%的人现在使用，16%的人曾经使用过。可燃烟草制品（几乎全部为香烟）使用率最高（16%），其次是 HTP（5%）。在可燃烟草制品使用者和 HTP 使用者中，分别有 70%和 16%的人单独使用这些产品。11%的受访者报告了双重使用。与调查前 12 个月相比，12%的单一可燃烟草制品使用者完全改用 HTP 或双重使用，6%的人完全停止使用烟草制品；94%的单一 HTP 使用者仍然是单一使用者，4%的人完全停止使用烟草制品；双重使用者中，12%的人恢复为单一可燃烟草制品使用者，14%的人转为单一 HTP 使用者，4%的人完全停止使用烟草制品。
结论
HTP 似乎被可燃烟草制品使用者接受为一种替代烟草产品。鉴于双重使用的复杂发现，深入了解这种行为背后的动机将是有益的。
