The Journal of the Korean Society for Research on Nicotine and Tobacco (J Korean Soc Res Nicotine Tob, JKSRNT) is an open access, peer-reviewed, online-only and an official journal of the Korean Society of Nicotine and Tobacco Research. It aims to provide a forum for empirical findings, critical reviews, and conceptual papers on the many aspects of nicotine and tobacco, including research from the behavioral, neuro biological, molecular biologic, epidemiologic, prevention, and treatments arenas. The published types of articles are original articles, review articles, brief communications, case reports, letters to the editor, and special invited contributions. The official language of the journal is Korean, but manuscripts written in English are also eligible.
Background: New tobacco products (referring to e-cigarettes and any other new tobacco-related products) are being promoted by the tobacco companies’ marketing activities and various user-generated contents. Contents showing enticing factors of new tobacco products exist in various forms especially in social media, which is easily accessible to the public.
Methods: This study is an exploratory content analysis that identifies enticing factors of new tobacco products in social media (YouTube), which has recently been used by the entire nation including children and adolescents. The analysis focused on the video uploader, characteristics and types of content, commercial components, and linguistic features of the message.
Results: The results show that most of the videos (76.7%) were uploaded by individuals who are classified as tobacco enthusiasts. However, several contents (30.0%) that contain a purchase link of the tobacco product exist without recognizing any sponsorship. The possibility of the hidden advertisement of tobacco companies could be inferred from those cases. Moreover, the videos contain a lot of sensory appeals like “OO flavor/scent” and “Feeling fresh after smoking,” which are likely to strongly influence children and adolescents.
Conclusion: Social media has provided many enticing contents of new tobacco products. Moreover, the contents, which are considered as advertising, were distributed among users without any regulation. Therefore, continuous and close monitoring of social media contents is required. In addition, practical policy implementation reflecting the social media environment should be considered.
Background: The relationship between the types of tobacco products and allergic diseases remains unclear. Hence, this study determined whether the current use of tobacco and combination of cigarettes, such as conventional cigarettes (CC), electronic cigarettes (EC), and heated tobacco products (HTP), among Korean adolescents affects the development of allergic diseases.
Methods: This cross-sectional study analyzed the data from the 15th Korean Youth Risk Behavior survey. Participants included 55,748 adolescents at the age of 13-18 years. We performed a multivariable logistic regression analysis and calculated odds ratios (ORs) and 95% confidence interval (CI) of having allergic diseases.
Results: Asthma, allergic rhinitis, and atopic dermatitis were reported by 1.5%, 20.0%, and 6.4% of the total participants, respectively. The rates of allergic diseases were the highest in EC and HTP users together. After adjusting for confounding variables, adolescents who used only HTP were associated with the highest risks of having asthma (OR, 6.80; 95% CI, 2.28-20.32) and atopic dermatitis (OR, 2.73; 95% CI, 1.11-6.76) compared with those who never used tobacco. Among adolescents who used EC and HTP together, the ORs of allergic rhinitis were the highest (OR, 1.79; 95% CI, 1.04-3.09).
Conclusion: The association with increased allergic diseases was relevant in adolescents who smoked, especially those who used combustible cigarette alternatives. We should be vigilant of the use of HTP, CC, and EC, the hazards of which are already known among adolescents.
Background: Previous studies have reported the association between receiving allowance and smoking rate in adolescents and the possibility of adolescents to work part-time jobs for purchasing tobacco. Part-time jobs among adolescents are becoming more common, the types and purposes of which have recently changed. We tried to assess the association between part-time job experience and smoking tobacco in adolescents.
Methods: We analyzed 62,276 subjects (49.2% girls) who participated in the 2017 Korea Youth Risk Behavior Survey. Frequency analysis, chi-square test, and logistic regression analysis were performed to understand the characteristics of variables, such as demographic and socioeconomic factors, and to analyze the association of part-time job experience with smoking tobacco as defined by ever-smokers.
Results: A total of 8,150 participants (19.3% boys and 6.6% girls) were ever-smokers. Among the 8,404 who had part-time job experiences (13.9% boys and 13.1% girls), the number of ever-smokers was higher (50.7% boys and 23.9% girls) than in those without part-time job experiences (14.3% boys and 4.0% girls). In logistic regression analysis, the risk for persons with part-time job experience to have a lifetime smoking experience was significantly higher (odds ratio, 2.49; 95% confidence interval, 2.32-2.68) after adjusting for the demographic, socioeconomic, and smoking-related factors.
Conclusion: Part-time job experience has a significant association with ever-smoking in Korean adolescents.
