ABSTRACT
Socioeconomic status (SES) has a large impact on the way individuals respond to environmental threats. However, less is known about how SES links to personal confidence in confronting COVID-19 and its underlying neural mechanisms. To this end, we assessed self-confidence in coping with pandemic on 606 participants during its peak in China from 21th, February, 2020 to 28th, February, 2020, who underwent magnetic resonance imaging (MRI) scanning before the outbreak from 17th, September, 2019 to 11th, January, 2020. We found that males, rather than females, showed heightened confidence levels as SES increased. Similarly, greater gray matter volumes (GMV) in the left hippocampus, which were identified as SES-related brain correlates using whole-brain voxel-based morphometry (VBM) method, predicted higher confidence level for males, whilst such association was not found among females. Moreover, an independent moderation analysis replicated the predictive role of GMV based on the pre-defined anatomical structure (i.e., left hippocampus). These findings suggested that relative to females, a less threat-biased evaluation style shaped by greater hippocampal volumes might account for the males’ adequate psychological resources for coping with the pandemic. Overall, evidence highlighted the importance to focus on specific populations like females, and people from lower SES in the era of pandemic.

Background A global public health emergency triggered by the Coronavirus Disease 2019 (COVID-19) epidemic may have a remarkable psychological impact on the population. There is still limited psychological research on police officers, especially on prison police. The present study aims to identify prevalence and influencing factors on mental health status among frontline prison police in China during the prevention and control of the COVID-19 epidemic.Methods A cross-sectional survey with a sample of 981 frontline prison police was conducted by using snowball sampling approach. The self-administered questionnaire consisted of 4 parts: (i) informed consent form; (ii) socio-demographic section; (iii) work and life situations during the prevention and control of the COVID-19 epidemic; (iv) the Chinese version of the 12-item General Health Questionnaire (GHQ-12). Univariate analysis and multivariable logistic regression were performed to identify factors influencing mental health status.Results The prevalence of being prone to mental health problems (GHQ-12 score ≥ 4) was 33.43% among frontline prison police. The results of GHQ-12 factors analysis that the prison police suffered from psychological issues related to anxiety and depression, which main symptoms were unhappy and depressed, lost sleep over worry and constantly under strain. Multivariate logistic regression analysis revealed that male (OR = 1.573, 95% CI: 1.385–1.853), work in closed jail (OR = 2.203, 95% CI: 2.139–2.297), more night shifts (OR = 2.163, 95% CI: 2.031–2.317 ; OR = 2.749, 95% CI: 2.194–2.901), more smoking (OR = 1.100, 95% CI: 1.037–2.168), poor physical condition (OR = 1.947, 95% CI: 1.478–2.250), chronic or serious illness history (OR = 1.870, 95% CI: 1.314–2.660; OR = 2.214, 95% CI: 1.460–2.812) were risk factor for mental health among frontline prison police, while regular diet (OR = 0.779, 95% CI: 0.539–0.928), more physical exercise (OR = 0.702, 95% CI: 0.548–0.899; OR = 0.641, 95% CI: 0.316–0.887), more communication with family members (OR = 0.437, 95% CI: 0.295–0.616) were protective factor.Conclusion The frontline prison police exhibited a high tendency toward mental health problems during the prevention and control of this epidemic. Therefore, continued surveillance of psychological problems and targeted mental health care for frontline prison police were urgently.
