Background: This study assessed the reasons for using heated tobacco products (HTPs) among South Korean adults according to demographic and socioeconomic factors.
Methods: An online panel survey was conducted from November 3 to 9, 2018, including 7,000 adults (4,700 females, 2,300 males) from 70,000 age-, sex-, and provincial-distributionmatched individuals, based on the 2018 national population statistics. Females were oversampled because their tobacco use prevalence was low. The reasons for using HTPs were investigated and ranked according to age, sex, education level, monthly income, and current HTP usage status. Descriptive statistics were then presented as unweighted numbers and weighted percentages.
Results: Of the 7,000 participants, 944 (16.8%) were ever HTP users. The most common reasons for using HTPs among ever HTP users were as follows: 쐍o ash is formed (74.8%) and 쐇t has less odor than conventional cigarettes (71.9%). Current HTP users responded with higher percentages for all the reasons, compared to former HTP users. HTP having 쐋ess odor than conventional cigarettes was the most important reason for younger smokers (20-34 years old) compared with those of other age groups. No significant differences were observed in the order of reasons for HTP use between males and females. People with higher education used HTPs to 쐒educe conventional cigarette use (41.4% vs. 30.9%), and people with higher income (over monthly income of 7000K won) used HTPs as it produced 쐋ess odor than conventional cigarettes (77.2%).
Conclusion: In South Korea, the most important reason for HTP use among current HTP users is the absence of ash and odor.
