Sleep research in 2020: COVID-19-related sleep disorders

摘要

2020 has been an unprecedented year because a modified coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), spread rapidly from China to all continents, leading to the COVID-19 pandemic. The first studies of COVID-19-associated sleep disorders were reported in China. Huang and Zhao1 collected information from a survey of 7236 volunteers (mean age 35·3 years [SD 5·6]). About a third of them were health-care workers. About 35% of these participants reported symptoms of general anxiety, 20% of depression, and 18% of poor sleep quality.1 The participants who were most worried about the pandemic also reported the most symptoms. Health-care workers were clearly under great pressure, which was reflected in the high prevalence of mental-health symptoms that they reported.1
