Major Depressive Episodes Linked to Discrimination Experienced by University Students
Key Clinical Summary
- Longitudinal Norwegian data show discrimination significantly increases risk of major depressive episode (MDE) among higher education students within 1 year.
- Sexual orientation and gender identity discrimination were most strongly associated with later MDE (relative risks [RRs] 1.3–2.9).
- A dose-response pattern emerged: students reporting ≥4 discrimination types had nearly 4-fold higher MDE risk.
A new longitudinal analysis from the national Norwegian SHoT2022 survey found that experiences of discrimination were associated with a higher risk of major depressive episodes (MDEs) among higher education students. Published in the Journal of Affective Disorders, the study provides rare prospective evidence linking multiple discrimination domains with clinically defined depression.
Study Findings
Researchers analyzed a subsample of 7884 Norwegian students aged 18–35 who completed the SHoT2022 survey and a follow-up diagnostic interview 1 year later. Baseline measures captured discrimination across 10 domains, including ethnicity, gender, sexual orientation, gender identity, disability, and political opinion. Current MDE at follow-up was assessed using the electronic Composite International Diagnostic Interview (CIDI 5.0).
Discrimination was commonly reported and varied by sex; gender-based discrimination was most prevalent among women, whereas political discrimination was more frequent among men. Overall, exposure to any discrimination predicted elevated risk of MDE, with adjusted relative risks ranging from 1.3 to 2.9.
Sexual orientation–based and gender identity–based discrimination emerged as the strongest predictors of subsequent MDE. The authors also reported that a dose-response pattern emerged; students reporting 4 or more discrimination types had nearly a 4-fold higher risk of developing an MDE compared with peers reporting no discrimination.
These associations remained significant even after adjusting for age, sex, and baseline psychological distress, suggesting that discrimination may independently contribute to worsening mental health trajectories.
Clinical Implications
For clinicians working with young adults and university populations, these findings emphasize the importance of assessing discrimination experiences as part of mental health evaluations. Mental health specialists, university health centers, and primary care clinicians may need to enhance screening strategies, integrate trauma-informed approaches, and ensure culturally and LGBTQ+-competent services.
The nearly 4-fold increase in depression risk for students experiencing multiple discrimination types also signals a subgroup requiring particular vigilance and early intervention.
Expert Commentary
“Discrimination is a robust and graded predictor of depression among students in higher education,” wrote Børge Sivertsen, Department of Health Promotion, Norwegian Institute of Public Health, Bergen, Norway, and study coauthors. “Findings underscore the need for inclusive mental health services and institutional efforts to prevent and address discrimination on campuses.”
However, the researchers cautioned that the use of self-reported, observational data may limit the study’s findings. Individuals with a history of depression were also excluded from the study, which may limit the findings’ generalizability to new-onset or recurrent MDE following the baseline survey.
Still, they emphasized that “the findings have clear implications for policy and practice.”

The SHoT2022 longitudinal findings reinforce discrimination as a potent, measurable risk factor for MDE among students. Strengthening inclusive clinical screening practices may be a critical step to protect student mental health and reduce depression risk.
