The impact of COVID-19 pandemic on mental burden and quality of life in medical students - results of an online survey.

Objectives: Changes in academic conditions due to the COVID-19 pandemic are potential stressors for medical students and can make them vulnerable for the development of psychiatric disorders.Previous pandemics had a negative impairment on well-being due to social isolation and the perceived threat, an increase in fear, anger and frustration and an increase in post-traumatic stress disorder among health professionals. Therefore, this study examines the impact of the COVID-19 pandemic on medical students' mental health and possible psychological consequences.

Methods: In this anonymous online survey (online 12/01/2021-03/31/2022), we examined the impact of COVID-19 pandemic on mental health of 561 German medical students aged between 18 und 45 years. Perceived anxiety and burden were assessed retrospectively from spring 2020 to autumn 2021. Changes in symptoms of anxiety and depression were assessed using the Hospital Anxiety and Depression Scale (HADS), quality of life was assessed using the WHO Quality of Life Questionnaire (WHOQOL BREF).

Results: Anxiety and burden showed wavelike courses with higher scores in autumn, winter and spring. The scores for depression and anxiety increased after the outbreak of the COVID-19 pandemic compared to the time before (p<.001). Results of a multifactorial ANOVA showed, that previous psychiatric illness (p<.001), being in the first two years of studies (p=.006), higher burden (p=.013) and greater differences in symptoms of depression (p<.001) were associated with a decreased quality of life in medical students.

Conclusion: The COVID-19 pandemic has a negative impact on mental health of medical students and their actual quality of life. Therefore, medical faculties should establish specific support to prevent the development of psychiatric sequelae probably resulting in long-term medical leaves.
