Investigation on health awareness, professional awareness and mental health status of medical students in a military school during the outbreak of novel Coronavirus pneumonia

Objective: To understand the health and professional consciousness and mental health of military medical students during coronavirus disease 2019 (COVID-19) epidemic. Methods: From Feb. 17 to Feb. 20, 2020, an electronic questionnaire was used to investigate the attitudes and coping styles of military medical students towards quarantine and delay of school opening, their attitudes towards online teaching, and health and professional consciousness during COVID-19 epidemic;and their mental health status was scored by symptom checklist 90 (SCL-90). Results: A total of 2 736 valid questionnaires were collected. The students basically understood and agreed with the quarantine and delay of school opening during the epidemic, and 70.83% (1 938/2 736) supported online teaching. During the quarantine period, 85.31% (2 334/2 736) of the students chose to listen to music or watch TV series for relaxation, and 64.69% (1 770/2 736) insisted on learning, reading literatures or writing papers. Students could basically form the habits of washing hands frequently and wearing masks, and their consciousness of health protection was higher than that before the epidemic. For military medical students, their professional beliefs and determination have been strengthened during the epidemic, and many students wanted to join in the fight against the epidemic. The survey found that 12.94% (354/2 736) of the students had mental health symptoms, and the top 3 SCL-90 factors were obsessive-compulsive disorder (78.53%, 278/354), interpersonal sensitivity (64.12%, 227/354), and depression (44.07%, 156/354). Conclusion: During the epidemic, military medical students can generally adapt to the difficult environment and improve themselves. The mental health problems of military medical students have their own characteristics, special attention must to be paid, and the humanistic education of medical students should be strengthened.

Beneficial for mental health, exercise more or less?

Regular physical activity may improve mental health during the pandemic by reducing inflammatory responses. However, overtraining or prolonged exercise training may adversely affect mental health.

Is Higher Subjective Fear Predictive of Post-Traumatic Stress Symptoms in a Sample of the Chinese General Public?

Background: COVID-19 has taken a huge toll on medical resources and the economy and will inevitably have an impact on public mental health. Post-traumatic stress disorder (PTSD), as the most common mental illness after an epidemic, must be seriously addressed. This study aimed to investigate the subjective fear of the Chinese general public during COVID-19 and to explore how it affected the development of PTSD. Methods: An online questionnaire survey was conducted among 1,009 people from January 30 to February 14, 2020 (about 1 month after the COVID-19 outbreak). The subjective fear was measured by a self-reported single-choice question. Four items from the Pittsburgh Sleep Quality Index (PSQI) were selected to measure the subjects' sleep quality. Their post-traumatic stress symptoms (PTSS) were measured by the PTSD Checklist for DSM-5 (PCL-5). Pearson correlation, hierarchical multivariate regression analysis, multiple mediator model, and bootstrapping were used in statistical analyses. Results: Different people showed different levels of subjective fear in response to the outbreak. There was a significant positive correlation between subjective fear and the total score of PCL-5 (R = 0.513, P < 0.01), meaning that the higher the degree of subjective fear, the more severe the symptoms of post-traumatic stress are. Subjective fear was an important predictor of PTSS, accounting for 24.3% of the variance. The total effect of subjective fear on PCL-5 scores was significant (total effect = 7.426, SE = 0.405, 95% CI = 6.631-8.221). The total indirect effect of subjective fear on PCL-5 scores through sleep quality was also significant (total indirect effect = 1.945, SE = 0.258, 95% CI = 1.436-2.470). Conclusions: Subjective fear has an important predictive effect on PTSS. In addition to the direct effect, our findings firstly demonstrate the mediating role of sleep quality in the relationship between subjective fear and PTSS.

The impact of the COVID-19 pandemic on the mental health of young people: A comparison between China and the United Kingdom.

PURPOSE: As COVID-19 spreads globally and affects people's health, there are concerns that the pandemic and control policies may have psychological effects on young people (age from 17 to 35 years). This psychological impact might vary in different countries, and thus we compared the prevalence of self-reported psychological distress, loneliness and posttraumatic stress symptoms (PTSS) among young people in the United Kingdom (UK) and China at the beginning of the COVID-19 pandemic. METHODS: Data of this study came from two sources. One source was the first wave of COVID-19 study in Understanding Society, a special wave of the UK household longitudinal study, which provided the high-quality, national-wide representative panel data. The sample comprised 1054 young people. The other source was an online survey on the mental health of 1003 young people from Shanghai, a highly developed area in China. The questionnaire included questions on the prevalence of common mental disorders (cut-off score ≥ 4), loneliness and potential PTSS (cut-off ≥ 33). Univariable analyses were conducted to test the differences in the self-reported prevalence of psychological distress and loneliness between the two groups. Multivariable logistic regression analyses were run to explore the predictors of psychological distress and loneliness among all the young people from England and Shanghai. RESULTS: Among the samples with self-reported psychological distress, the UK sample accounted for 34.4% (n=1054) and the Chinese sample accounted for 14.1% (n=1003). The difference between the two groups was statistically significant (p < 0.001). Additionally, 57.1% of people in the UK and 46.7% in China reported that they sometimes or often felt lonely, of which the difference is statistically significant (p < 0.001). Regression analysis of the entire samples showed that nationality, gender, psychotherapy and loneliness were significant predictors of 12-item General Health Questionnaire scores, while the variables of age and living alone were not. Significant predictors of self-reported loneliness were the nationality, gender, age, living alone and psychotherapy. In China, 123 (12.3%) young people, 49 men (11.3%) and 74 women (13.0%), met the criteria of PTSS symptoms (cut-off scores ≥ 33). These scores were only collected in China. CONCLUSION: This evidence suggests that mental health and loneliness reported by young people were lower in China than that in the UK during the studied period. More research is needed to understand these differences. If the differential negative psychological impacts are confirmed, country-specific measures of prevention and intervention should be adopted to improve the mental health of young people under the ongoing impact of the pandemic.
