Trends of electronic cigarette use among adolescents: A bibliometric analysis.

INTRODUCTION: The use rate of electronic cigarettes (e-cigarettes) among adolescents is continuously rising globally, posing new challenges to public health and negatively impacting adolescent health. This study employs bibliometric methods to systematically present the current state and evolving trends in global research on adolescent e-cigarette use. METHODS: This study uses CiteSpace to conduct a bibliometric analysis of articles related to adolescent e-cigarette use from the Web of Science (WoS) Core Collection database. Firstly, performance analysis and collaboration network analysis were utilized to clarify the basic publication status, main knowledge producers, and knowledge collaboration networks in adolescent e-cigarette use research. Secondly, a co-citation network analysis was performed to visually analyze the disciplinary characteristics and 'hot topics' in this field. Finally, keyword burst detection and clustering techniques were employed to further explain the development trends and frontiers of research on adolescent e-cigarette use. RESULTS: A total of 2063 research articles and review articles were included in this study. Research on adolescent e-cigarette use has significantly increased from 2002 to 2024. The United States, the United Kingdom and Canada are the main contributors, with their institutions and researchers playing key roles in the international collaborative network. Current research increasingly adopts interdisciplinary approaches. Keyword co-occurrence and burst identified current research 'hotspots' including vaping, substance use, public policy, prevention, advertising, and cessation. Co-citation cluster analysis revealed promising research areas such as attractiveness, environment and health, accessibility and smoking behavior, and mental health. CONCLUSIONS: Through data mining and visualization techniques, this study provides a comprehensive bibliometric analysis of published work on e-cigarettes and adolescence. The results of this work offer references for researchers in future investigations.

Association between exposure to tobacco information through mass media, smoking households and secondhand smoke exposure in adolescents: Survey data from South Korea.

INTRODUCTION: To explore the current situation of exposure of Korean adolescents to secondhand smoke (SHS) in households our study aimed to determine the relationship between family member smoking status, exposure to tobacco information through mass media, and household SHS exposure. METHODS: The present study uses pooled data from the Korean adolescent health behavior online survey conducted in 2015, 2018 and 2021, with 157944 participants. The regression models were used to explore the association between the smoking status of households, and exposure to tobacco information through mass media, and household SHS exposure in adolescents, controlling for potential confounding factors. RESULTS: SHS exposure duration of Korean adolescents in households was 0.88 days per week. The households with smokers including the father (ß=1.087; 95% CI: 1.0-1.126), mother (ß=1.461; 95% CI: 1.379- 1.543), siblings (ß=0.545; 95% CI: 0.493-0.597), grandparents (ß=0.224; 95% CI: 0.174-0.272), and other relatives (ß=0.170; 95% CI: 0.126-0.214), showed a positive association with SHS exposure in adolescents within the household. At the same time, information about anti-smoking ads on television (ß= -0.042; 95% CI: -0.069 - -0.015) and public transportation (ß= -0.031; 95% CI: -0.054 - -0.010), showed a negative association with SHS exposure in adolescents. However, broadcasts, online, and newspaper non-smoking ads were not associated with SHS exposure (p>0.05). In addition, regression models revealed that exposure to cigarette advertising in magazines (ß=0.131; 95% CI: 0.097-0.166), networks (ß=0.151; 95% CI: 0.127-0.175), convenience stores (ß=0.061; 95% CI: 0.035-0.087), and supermarkets (ß=0.133; 95% CI: 0.108-0.158) is associated with SHS exposure in adolescents. Finally, our study showed stronger ties between SHS exposure, family smoking, and tobacco ads in girls. The link between maternal smoking, supermarket ads, and adolescent SHS exposure intensified in 2021 compared to 2015. CONCLUSIONS: Family and media were identified as potential factors associated with SHS exposure in adolescents. Therefore, publicity and education regarding household SHS hazards, and smoking bans in media, can be helpful in protecting adolescents from SHS.
