Mental Health During the Covid-19 Outbreak in China: a Meta-Analysis

Area of Science:

• Public Health
• Epidemiology
• Mental Health Research

Background:

• The COVID-19 pandemic rapidly spread globally, necessitating strict public health interventions like lockdowns and isolation.
• Despite the significant mental health implications, previous studies on the impact of COVID-19 in China yielded inconsistent results.
• A meta-analysis was conducted to synthesize existing research and provide a clearer understanding of the pandemic's mental health burden.

Purpose of the Study:

• To systematically analyze and synthesize the incidence of anxiety and depression among populations affected by the COVID-19 pandemic.
• To provide a quantitative overview of the mental health impact of the COVID-19 outbreak in China.
• To identify potential sources of heterogeneity in previous studies concerning mental health outcomes during the pandemic.

Main Methods:

• A comprehensive literature search was performed across Embase, PubMed, and Web of Science for studies published between December 2019 and April 2020.
• Studies focusing on COVID-19 and mental health were included, while reviews, case reports, letters, and comments were excluded.
• A random-effects model was employed to synthesize data from 12 selected studies, encompassing 27,475 subjects, to estimate the pooled prevalence of anxiety and depression.

Main Results:

• The meta-analysis included 12 studies with a total of 27,475 participants.
• The pooled incidence of anxiety was estimated at 25% (95% CI: 0.19-0.32), and the pooled incidence of depression was 28% (95% CI: 0.17-0.38).
• Significant heterogeneity was observed across the included studies, necessitating further subgroup and sensitivity analyses to explore potential contributing factors.

Conclusions:

• The pooled prevalence of anxiety and depression during the COVID-19 pandemic, while significant, should be interpreted cautiously due to substantial heterogeneity across studies.
• The ongoing nature of the epidemic underscores the critical need for robust, integrated crisis prevention systems.
• These systems should encompass epidemiological monitoring, systematic screening, and proactive psychological interventions to mitigate the mental health impact of public health emergencies.
