      The PRISMA guideline was used to conduct this review. By searching relevant keywords in databases of Scopus, PubMed, Web of Science, and Google Scholar, studies that reported the prevalence of insomnia among HCWs during the COVID-19 pandemic (January 2020 to the end of January 2021) and had been published in English were identified and evaluated. The random effects model was used for meta-analysis, and the I2 index was used to assess heterogeneity. The Egger test was used to determine publication bias. Based on the results of the primary search, 96 studies were identified, and ultimately 10 eligible studies entered the meta-analysis phase.
