This trend, which is concerning, requires a systematic bibliometric analysis to develop effective preventive and remedial measures. OBJECTIVE: This study aims to identify and analysis the research hotspots, frontiers and emerging trends in the field of high school students' mental health over the past two decades using CiteSpace software. These findings provide important insights that can shape future research agendas and guide targeted interventions to improve the mental health outcomes of this vulnerable group. METHODS: This study utilized the Web of Science Core Collection database as its data source to retrieve literature pertaining to high school students' mental health from January 1, 2004, to January 1, 2023. The initial search yielded 1,764 relevant documents.

The research employed the CiteSpace 6.2.R4 tool to evaluate various bibliometric indicators of the included literature, including statistics on institutional and author publication volumes, as well as co-citation analysis. RESULTS: A total of 1,748 English-language documents were retrieved, showing an upward trend in publications on high school students' mental health from 2004 to 2024. The research hotspots primarily focus on COVID-19 pandemic, depression, bullying, substance abuse, sexual behavior, Physical Education and their relationships with the mental health of high school students. Future research trends may focus on studies investigating the relationships between the use of electronic cigarettes, sleep disorders, internet addiction, and the mental health of high school students.
