Mental Health During the Omicron Pandemic: A Comparison Between Medical Staff and Non-medical Staff

Background: A considerable number of people suffered from mental disorders due to coronavirus disease 2019 (COVID-19). As the virus mutated, the effect of COVID-19 changed. This study intends to compare the mental health between the medical staff and non-medical staff during the Omicron pandemic, and to analyze the relevant risk factors.

Methods: The cross-sectional study was conducted by a set of online questionnaires, 1246 medical staff and 1246 non-medical staff were selected after a 1:1 propensity score matching. The questionnaires included the demographic characteristics, the Coronavirus Anxiety Scale (CAS), the Center for Epidemiologic Studies Depression Scale (CES-D), the Insomnia Severity Index Scale (ISI), and the Psychological Resilience Scale(CD-RISC).

Results: Compared with medical staff, non-medical staff scored higher on CAS and CES-D (both P < 0.001). Non-medical staff had higher prevalence of anxiety (55.0 % versus 47.3 %; adjusted OR = 1.45, 95 % CI = 1.23-1.70), depression (62.4 % versus 53.4 %; adjusted OR = 1.46, 95 % CI = 1.23-1.73) and insomnia (46.5 % versus 43.4 %; adjusted OR = 1.21, 95 % CI = 1.02-1.43). Multivariate logistic regression analysis showed that being female, being younger than 40 years, having an annual income of <50,000 yuan, paying attention to omicron, in the course of an infection and below bachelor degree influenced anxiety, depression and insomnia of the medical staff and non-medical staff to different degree.

Limitations And Conclusions: This study only collected data through the network. Therefore, the validity was reduced to some extent. The outbreak of the Omicron epidemic posed a significant challenge to public mental health, with non-medical staff at the highest risk for mental health problems.
