Main idea: The prevalence of sleep problems during the COVID-19 pandemic is high and affects approximately 40% of people from the general and health care populations. Patients with active COVID-19 appeared to have a higher prevalence rates of sleep problems.
No systematic review or meta-analysis has yet been conducted to examine the impact of the pandemic on the prevalence of sleep problems among the general population, health care workers, or patients with COVID-19. Therefore, this systematic review was conducted to assess the impact and prevalence of sleep problems among those categories.
Results: Forty-four papers, involving a total of 54,231 participants from 13 countries, were considered relevant and contributed to the systematic review and meta-analysis of sleep problems during COVID-19. The global pooled prevalence rate of sleep problems among all populations was 35.7%. Patients with COVID-19 appeared to be the most affected group, with a pooled rate of 74.8%. Health care workers and the general population had comparative rates of sleep problems, with rates of 36.0% and 32.3%, respectively.
