O impacto da pandemia COVID-19 na qualidade do sono pelo Índice de Qualidade do Sono de Pittsburgh: uma revisão sistemática

Abstract

This article aims to evaluate the sleep quality in individuals during the pandemic caused by coronavirus disease 2019 (Covid-19) by Pittsburgh Sleep Quality Index (PSQI). Searches were conducted in the PubMed, Embase, Web of Science, and PEDro databases, on May 22, 2020. In the publications, 208 articles were found and, considering the eligibility criteria, 10 articles were included at the end, showing the effects on sleep quality during the pandemic, in populations hospitalized, quarantined, and in frontline health professionals. The PSQI measured sleep disorders and a higher score indicated poor sleep quality. Nine articles were classified with evidence level IV and one as level III-2. Eight studies presented a “serious” risk of bias and two “moderate.” The studies investigated different populations and described the results as “poor” sleep quality, considering the PSQI on quarantined individuals and frontline health professionals as the most committed. A poor sleep quality was found in the populations evaluated in the selected publications due to the Covid-19 to contribute as a risk factor for mental health. It is suggested that psychological interventions must be made to minimize the consequences through social support and social capital
