ABSTRACT
INTRODUCTION: COVID-19 has a serious impact on people's physical health and mental health. The COVID-19 pandemic forced college and university students to take online classes, which may have bad impacts on students' learning. In addition, the students lost many job opportunities during the pandemic. Faced with employment and study pressure and worried about the epidemic, college and university students were prone to increased overall negative emotion, anxiety and depression. Therefore, this systematic review and meta-analysis will be conducted to explore the impact of the COVID-19 pandemic on the mental health and learning of college and university students. METHODS AND ANALYSIS: We will conduct electronic literature search of the PubMed, Embase, Cochrane Library, Web of Science and Chinese National Knowledge Infrastructure databases. Two researchers will independently screen the studies, extract data and assess the quality of the included studies. Any disagreement will be resolved by the third investigator. The Newcastle-Ottawa Scale and other tools will be used to assess the risk of bias, according to the study design of included studies. OR, risk ratio, mean difference and 95% CI will be considered as the effect size. Heterogeneity between studies will be assessed by subgroup and sensitivity analysis, and publication bias will be detected by funnel plots, Begg's test and Egger's test. ETHICS AND DISSEMINATION: This systematic review and meta-analysis involves no patient contact and no interaction with healthcare providers or systems. We will disseminate the findings of this study through the presentation at scientific conferences and publication in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42020201132.
