How do students cope with stress during remote learning due to COVID-19 pandemic? Biological and psychological factors-protocol of the study

Abstract

Abstract Introduction: The COVID-19 pandemic negatively affected the mental health of the Polish population. Students are the group with a high risk of developing mood disorders. The scientific data suggest the usefulness of biological substances as potential biomarkers of psychiatric disorders. Saliva is non-invasive, quick to obtain material and a promising fluid for measuring stress and depression severity. In this paper, we present the protocol of our study, which aims to assess the utility of concentrations of biological fluids as potential biomarkers of the stress response and risk of developing depression and anxiety disorders among students of Lublin. Materials and methods: Total number of 80 students were included in the study. Participants were asked to collect saliva samples simultaneously with responding to the questionnaires concerning their mental state. Afterwards, the samples were examined with an ELISA test to assess the level of fibroblast growth factor (FGF-2), cortisol and chromogranin A (CgA). The relationship between biomarkers and severity of stress, depression, anxiety will be examined. Results: Cortisol on its own is not a good material to investigate the stress reaction in saliva due to its variable levels among people during stressful situations. Scientific data indicate the usefulness of other biomarkers or their combination to indicate the potential risk of developing depression and/or anxiety. Conclusions: Introducing objective tests, helpful for mood symptoms recognition, would improve the prevention and diagnosis of psychiatric disorders in vulnerable populations.
