AbstractIntroduction: The present study examined experiences of discrimination, discrimination-related vigilance, stress, fatigue, and poor sleep among students at the University of Arizona. Methods: Data were collected using an online survey. Students indicated if they had experienced discrimination and discrimination-related vigilance. Subjects answered a question about their sleepiness in the last 7 days and also answered questions about their sleep, fatigue, and psychological symptoms using the PSQI, the ISI, the FSS, the PSS, and the PHQ9. Relationships among sleep, vigilance, and discrimination were examined and adjusted for age, sex, race/ethnicity and estimated GPA. Partial mediation analyses examined whether hypervigilance score partially mediated relationships between EDS or MED and sleep variables. Results: EDS and MED scores were associated with overall sleep quality, insomnia severity, sleepiness, fatigue, sleep latency, and total sleep time. When stress or depression were added to the model, most of these results became non-significant. The relationships between EDS and MED score and sleep variables were, in many cases, significantly partially mediated by hypervigilance score. Conclusion: College students who report discrimination report more sleep disturbances. About 30-70% of these relationships are explained by hypervigilance score. The relationship between stress/mood and sleep subsumed much of the relationship between discrimination and sleep.
