Trends in global research on tobacco use among sexual and gender minorities: A bibliometric analysis, 1984-2024.

INTRODUCTION

Globally, sexual and gender minorities (SGM) exhibit significantly higher tobacco use rates than their cisgender heterosexual counterparts, a persistent health disparity that has garnered increasing attention in public health research.

METHODS

We conducted a bibliometric analysis of 704 SGM tobacco use-related publications from the Web of Science Core Collection. First, we examined publication trends, key contributors, and collaborative networks. Second, we performed co-citation network analysis to identify disciplinary characteristics and research hotspots. Finally, we applied keyword burst detection and clustering techniques to assess emerging trends and frontier areas.

RESULTS

From 1984 to 2024, research on SGM tobacco use demonstrated consistent growth. The US accounted for the majority of publications (82.52%), with institutions such as the University of California System serving as key hubs for research collaboration. Research hotspots clustered around five key themes: 1) the effects of novel tobacco products, 2) subgroup differences in tobacco use, 3) tobacco-related health disparities, 4) smoking cessation research, and 5) social and psychological mechanisms.

CONCLUSIONS

Using data mining and visualization techniques, this study constructed a comprehensive knowledge map of research on SGM tobacco use. Our findings elucidate evolving patterns and emerging trends while offering valuable perspectives to guide future investigations.
