In this study, we aimed to investigate the prevalence of poor mental health and its association with loneliness and social support among 3531 undergraduate students in nine Asian countries. Mental health was assessed using the Self-Reporting Questionnaire, which was developed by the World Health Organization. Across the entire sample, we detected that nearly half of the students reported poor mental health according to the Self-Reporting Questionnaire and nearly one out of seven students felt lonely. While feeling lonely increased the odds of experiencing poor mental health (odds ratio [OR]), moderate (OR: 0.35) and strong social support (OR: 0.18) decreases the odds of experiencing poor mental health. The high prevalence of poor mental health calls for further in-depth investigations and implementation of mental health support interventions.

The worldwide prevalence of anxiety disorders among college students is high, which negatively affects countries, schools, families, and individual students to varying degrees. This paper reviews the relevant literature regarding risk factors and digital interventions for anxiety disorders among college students from the perspectives of different stakeholders. Risk factors at the national and societal levels include class differences and the coronavirus disease 2019 pandemic. College-level risk factors include the indoor environment design of the college environment, peer relationships, student satisfaction with college culture, and school functional levels. Family-level risk factors include parenting style, family relationship, and parental level of education. Individual-level risk factors include biological factors, lifestyle, and personality. Among the intervention options for college students' anxiety disorders, in addition to traditional cognitive behavioral therapy, mindfulness-based interventions, psychological counseling, and group counseling, digital mental health interventions are increasingly popular due to their low cost, positive effect, and convenient diagnostics and treatment. To better apply digital intervention to the prevention and treatment of college students' anxiety, this paper suggests that the different stakeholders form a synergy among themselves. The nation and society should provide necessary policy guarantees, financial support, and moral and ethical supervision for the prevention and treatment of college students' anxiety disorders. Colleges should actively participate in the screening and intervention of college students' anxiety disorders. Families should increase their awareness of college students' anxiety disorders and take the initiative to study and understand various digital intervention methods. College students with anxiety disorders should actively seek psychological assistance and actively accept and participate in digital intervention projects and services. We believe that in the future, the application of methods such as big data and artificial intelligence to improve digital interventions and provide individualized treatment plans will become the primary means of preventing and treating anxiety disorders among college students.

Objectives: In the post-covid-19 era, students face numerous mental health-related effects. Returning to Chinese institutions, international students in China experienced mental health issues (anxiety and stress). These overseas students' psychological issues are obstacles to their academic performance in China. Students' fear restructured their ability to think critically and execute effectively. Consequently, the framework of this study is intended to emphasize the beneficial effects of offline activities, physical activity, and classroom activities on reducing anxiety among international students in China. Methods: This study is predicated on survey data acquired using a five-point Likert scale. 317 responses were received from overseas students enrolled in Hainan universities. Results: The findings show that offline, physical, and classroom activities substantially impact the anxiety reduction of overseas students in China. The study's contribution to the literature is a fresh concept that previous research has not addressed. In addition, this research has significant theoretical and practical consequences for both knowledge and findings. Conclusion: The study has given a paradigm for relieving anxiety among overseas students in China by addressing a research gap. Meanwhile, this study's limitations provide a roadmap for researching further areas of literature in the future.
