Heated tobacco products (HTPs) have been widely used in Korea since their introduction in 2017. In this study, we investigated the perceptions of their relative harmfulness and smoking cessation effects. We performed an online survey in 7000 Koreans in 2018 (2300 males and 4700 females aged 20–69 years) by matching their age, sex, and provincial distribution. To investigate the factors causing HTPs to be perceived as less harmful than combustible cigarettes (CCs) and helpful for smoking cessation, we used multivariable logistic regression analyses. HTPs were less harmful than CCs in 16.8% of participants, particularly among HTP-only users and dual and triple users of HTPs, electronic cigarettes (ECs), or CCs than among CC-only users, those who were aged ≤ 34 years, males, and those with higher incomes. HTPs were reportedly helpful for smoking cessation in 11.2% of participants. Similar perceptions were more likely among HTP-only users, as well as dual and triple users than among CC-only users and adults with higher education/incomes. Although Korean adults generally had negative perceptions of the harmfulness and smoking cessation effects of HTPs compared with CCs, dual and triple users were more likely to have positive perceptions. Monitoring the use of multiple tobacco products and HTPs is a new challenge for Korean policymakers.

韩国成年人对加热烟草制品与可燃香烟相比的危害性及其戒烟效果的看法。


自 2017 年推出以来，加热烟草产品 (HTP) 在韩国得到了广泛使用。在这项研究中，我们调查了人们对其相对危害性和戒烟效果的看法。 2018 年，我们对 7000 名韩国人（20-69 岁的 2300 名男性和 4700 名女性）进行了在线调查，匹配了他们的年龄、性别和省份分布。为了调查导致 HTP 被认为比可燃卷烟 (CC) 危害更小且有助于戒烟的因素，我们使用了多变量逻辑回归分析。在 16.8% 的参与者中，HTP 的危害低于 CC，特别是在仅使用 HTP 的用户以及 HTP、电子烟 (EC) 或 CC 的双重或三重使用者中，与仅使用 CC 的用户（年龄 ≤ 34 岁的男性）相比，以及收入较高的人。据报道，HTP 对 11.2% 的参与者戒烟有帮助。类似的看法在仅 HTP 用户以及双重和三重用户中比仅 CC 用户和受过高等教育/收入的成年人更有可能出现。尽管与 CC 相比，韩国成年人普遍对 HTP 的危害和戒烟效果持负面看法，但双重和三重使用者更有可能持积极看法。监测多种烟草产品和加热烟草制品的使用情况对韩国决策者来说是一个新的挑战。
