Mental Health in College Students: From Epidemiological Findings to Sustainable Policies

Higher education has seen rising enrollment, mobility, and diversity; there are approximately 254 million students globally, a figure that has doubled since the early 2000s. The college years (roughly the age range between 18 and 30) coincide with key developmental phases marked by personal, social, and academic stressors like leaving home and adjusting to new environments. This period is high-risk for mental health issues such as anxiety and depression, which negatively affect academic success and future quality of life. The COVID-19 pandemic challenged students' mental health due to isolation, online learning, and fears of infection. Despite growing emotional problems, many students do not seek help, and this avoidance results in inadequate treatment and fragmented mental health services. These issues present significant challenges in addressing mental health within higher education and beyond. The goal of this article is to offer a thorough, critical review of the existing research on college mental health, including key data-driven epidemiological findings on mental disorders, theory-driven approaches to challenges faced during college, and prospects for future research.
