Insights
This study identified three mental health subgroups among medical students during COVID-19. Factors like demographics and COVID-19 knowledge influenced depression and anxiety, informing targeted mental health support.
Area of Science:
- Medical Education
- Psychiatry
- Public Health
Background:
- The COVID-19 pandemic created a global health emergency, significantly impacting medical students' mental well-being.
- Understanding depression and anxiety patterns in this demographic is crucial for developing effective support strategies.
Purpose of the Study:
- To identify distinct subgroups of medical students based on depression and anxiety symptoms during the COVID-19 epidemic in China.
- To explore the factors influencing these mental health subgroups.
Main Methods:
- Latent class analysis was used to categorize 29,663 medical students based on depression (PHQ-9) and anxiety (GAD-7) symptoms.
- Multinomial logistic regression identified factors associated with different mental health classes.
Main Results:
- Three subgroups emerged: low symptoms (16,017), mild mental health (9,321), and poor mental health (4,325).
- Factors influencing poor and mild mental health included sex, education, drinking, psychiatric history, COVID-19 knowledge, infection fear, and mental health education participation.
Conclusions:
- Latent class analysis effectively categorizes medical students by mental health status during health crises.
- Demographics, disease history, COVID-19 specific factors, and lifestyle significantly influence mental health outcomes.
- Targeted psychological interventions for distinct subgroups are recommended to enhance medical students' overall well-being.
Objective:
The novel coronavirus disease 2019 (COVID-19) is a global public health emergency that has caused worldwide concern. The mental health of medical students under the COVID-19 epidemic has attracted much attention. This study aims to identify subgroups of medical students based on depression and anxiety and explore the influencing factors during the COVID-19 epidemic in China.
Methods:
A total of 29,663 medical students were recruited during the epidemic of COVID-19 in China. Depression and anxiety symptoms were assessed using Patient Health Questionnaire 9 (PHQ9) and Generalized Anxiety Disorder 7 (GAD7) respectively. Latent class analysis was performed based on depression and anxiety symptoms in medical students. The latent class subtypes were compared using the chi-square test. Multinomial logistic regression was used to examine associations between identified classes and related factors.
Results:
In this study, three distinct subgroups were identified, namely, the poor mental health group, the mild mental health group and the low symptoms group. The number of medical students in each class is 4325, 9321 and 16,017 respectively. The multinomial logistic regression results showed that compared with the low symptoms group, the factors influencing depression and anxiety in the poor mental health group and mild mental health group were sex, educational level, drinking, individual psychiatric disorders, family psychiatric disorders, knowledge of COVID-19, fear of being infected, and participate in mental health education on COVID-19.
Conclusions:
Our findings suggested that latent class analysis can be used to categorize different medical students according to their depression and anxiety symptoms during the outbreak of COVID-19. The main factors influencing the poor mental health group and the mild mental health group are basic demographic characteristics, disease history, COVID-19 related factors and behavioural lifestyle. School administrative departments can carry out targeted psychological counseling according to different subgroups to promote the physical and mental health of medical students.
