Background: Covid-19 has started to spread within China since the end of December 2019. Despite government's immediate actions and strict control, more and more people were infected every day. As such a contagious virus can spread easily and rapidly between people, the whole country was put into lockdown and people were forced into isolation. In order to understand the impact of Covid-19 on mental health well-being, Chinese researchers have conducted several studies. However, no consistent results were obtained. Therefore, a meta-analysis was conducted. Methods: We searched Embase, PubMed, and Web of Science databases to find literature from December 2019 to April 2020 related to Covid-19 and mental health, among which results such as comments, letters, reviews and case reports were excluded. The incidence of anxiety and depression in the population was synthesized and discussed. Results: A total of 27,475 subjects were included in 12 studies. Random effect model is used to account for the data. The results showed that the incidence of anxiety was 25% (95% CI: 0.19-0.32), and the incidence of depression was 28% (95% CI: 0.17-0.38). Significant heterogeneity was detected across studies regarding these incidence estimates. Subgroup analysis included the study population and assessment tools, and sensitivity analysis was done to explore the sources of heterogeneity. Conclusions: Owing to the significant heterogeneity detected in studies regarding this pooled prevalence of anxiety and depression, we must interpret the results with caution. As the epidemic is ongoing, it is vital to set up a comprehensive crisis prevention system, which integrating epidemiological monitoring, screening and psychological crisis prevention and interventions.

Background This study aimed to find out eight months into the COVID-19 outbreak, how much psychological effect was experienced by convalescent psychiatric patients, and identify the potential risk and protective factors related to their psychological response. Methods Data from 136 convalescent psychiatric patients were collected. We used binary logistic regression analyses to identify participants’ SRQ score and the factors associated with it. Results There were 47 (34.5%) participants scored eight or higher. Working or marital status and annual income were significantly associated with a higher score in SRQ. Similarly, sleep duration, interpersonal relationship, exercise time, special events, and general condition were linked to SRQ grade. Conclusions Eight months into the COVID-19 pandemic, this widespread virus psychologically impacted convalescent psychiatric patients. This result was related to less annual income, which stressed the necessity to provide closer follow-up and financial support in this crisis's late stage.
