 Abstract
Background
Cigarette smoking is prevalent among low socioeconomic level, which contributes to the inequality of health in Korea. However, the relationship between heated tobacco products (HTPs) use and socioeconomic position is not well known. We investigated the relationship between current HTP use and socioeconomic position in Korean adults.
Methods
We analyzed 193,220 adults from 2019 Community Health Survey. Participants were categorized to either current HTP users or non-users of conventional cigarettes (CCs), electronic cigarettes (ECs), and HTPs. Socioeconomic factors including income, education, occupation, along with marital status and drinking status were evaluated by each gender. Multivariable logistic regression analysis was performed to evaluate the association between HTP use and socioeconomic positions.
Results
There were 4,572 current HTP users, comprised of 985 HTP-only users (20.9%), 2,465 CCs/HTPs dual-users (53.3%), 251 ECs/HTPs dual-users (5.6%), and 871 triple product users (20.1%). The adjusted ORs and 95% CIs for male were higher in university graduates and non-manual workers (2.97, 2.53~3.47). No significant relationship was found between income and current HTP use. For female, the odds were higher in 1st quartile (2.68, 1.86~3.86), high school graduates (2.88, 2.19~3.79), and manual workers (2.03, 1.54~2.67). Both males and females showed higher odds in young age, separated/bereaved/divorced and binge drinkers group, but differed in other socioeconomic factors.
Conclusion
In male, prominent use of HTPs in higher socioeconomic class such as higher education and having occupation, demonstrates new challenge in establishing tobacco regulation policies. In female, socioeconomic inequalities were identified and therefore, gender specific strategy is required.
