Abstract

Objective
This study seeks to evaluate the association between the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and the severity of depression and anxiety in the Korean community during the period dominated by the Omicron variant.
Methods
We used data from the 2022 Daejeon Mental Health Survey, involving data of 985 participants aged 19–69 years. The data collected included SARS-CoV-2 infection experience, days post-infection, and depression and anxiety symptoms evaluated using the Patient Health Questionnaire-9 and the Generalized Anxiety Disorder Questionnaire-7, respectively. Additionally, physical health, social activity status, and sociodemographic characteristics such as gender, age, marital status, educational level, and household income were collected. The association between SARS-CoV-2 infection and depression and anxiety were examined. Further analyses explored association between days post- infection and the severity of depression and anxiety.
Results
There was no significant correlation between SARS-CoV-2 infection and depression and anxiety in the overall population. Notably, participants under 50 years of age exhibited a transient worsening of depression and anxiety, followed by a decrease in symptoms within 40 days. Participants aged 51 years and older showed no significant change in depression and anxiety.
Conclusion
This study discerned transient effects of Omicron variant infection on depression and anxiety, particularly in younger individuals. A prospective study encompassing a larger sample size is imperative to investigate the influence of SARS-CoV-2 infection on depression and anxiety.
