The impact of lifestyle factors on the mental health of individuals working and studying at the American University of Sharjah (AUS)

Purpose This paper aims to explore the relationship between various lifestyle factors and symptoms of anxiety and depression among individuals working and studying at the American University of Sharjah (AUS), a multicultural academic environment in the UAE. Design/methodology/approach A cross-sectional observational study was conducted during the 2023–2024 academic year using self-administered online surveys. A stratified random sample of 451 participants completed validated instruments: PHQ-9 for depression, GAD-7 for anxiety and the Lifestyle Medicine Assessment Tool. Statistical analysis, including univariate and binary logistic regression, was performed using SPSS to identify significant predictors. Findings Moderate to severe symptoms of depression and anxiety were reported by 64.5% and 54.8% of participants, respectively. Key risk factors included younger age, female gender, unmarried status, and student role. Lower scores in movement, recovery and nutrition domains were significantly associated with mental health symptoms. Faculty and staff were less likely than students to report poor mental health outcomes. Research limitations/implications As a cross-sectional study based on self-reported data, causal relationships cannot be inferred, and response bias is possible. Further longitudinal studies are recommended. Practical implications The results emphasize the importance of promoting healthy behaviors, especially physical activity, adequate recovery and balanced nutrition, within academic institutions to enhance mental well-being and academic performance. Social implications This research sheds light on the widespread mental health challenges faced by university communities, particularly in the Middle East, and calls for a societal shift toward proactive mental health promotion. Addressing lifestyle determinants of mental health not only benefits individual well-being but also fosters a supportive academic environment. By emphasizing social connection, physical movement and recovery, institutions can reduce stigma, encourage openness, and promote community resilience. The study advocates for inclusive mental health policies and culturally sensitive health promotion strategies that can be scaled to similar academic settings regionally and globally. Originality/value This is among the first UAE-based studies to link lifestyle domains with mental health outcomes in a university context using validated tools. The findings can inform tailored wellness strategies in higher education settings.
