RESUMO
Due to the COVID-19 pandemic, the Higher Education Institutions had to suspend their on-site activities and adapt to the new scenario. Therefore, the objective of the research was to investigate the effects of the COVID-19 pandemic on the mental health of the academic community of a Brazilian public university. This is a cross-sectional study, at a Brazilian public university, that used the baseline data from a longitudinal study carried out with employees and students. Participants answered a self-administered and confidential questionnaire in online platform, composed of sociodemographic, economic, lifestyles and mental health issues. 1,353 students and 372 employees participated. The prevalence of anxiety disorder symptoms among students and employees was 46.12% and 17.47%, depression 54.62% and 22.85% and stress 47.45% and 22.58%, respectively. The co-occurrence of symptoms was 33.56% among university students and 10.75% among employees. Falling family income, having stopped smoking and negative self-rated health, during the COVID-19 pandemic, may be the reasons for the high prevalence of co-occurrence of anxiety, depression and stress disorders among the academic community.
