BARROS, Marilisa Berti de Azevedo et al. Report on sadness/depression, nervousness/anxiety and sleep problems in the Brazilian adult population during the COVID-19 pandemic. Epidemiol. Serv. Saúde [online]. 2020, vol.29, n.4, e2020427.  Epub Aug 20, 2020. ISSN 1679-4974.


To analyze the frequency of sadness, nervousness, and sleep disorders during the COVID-19 pandemic in Brazil, identifying the most affected demographic segments.


This was a cross-sectional study using an online questionnaire answered by adults and elderly people to collect information on living conditions, health and health-related behaviors. Prevalence rates and prevalence ratios adjusted for age and sex were estimated.


The data on 45,161 Brazilian respondents showed that during the pandemic 40.4% (95%CI 39.0;41.8) frequently felt sad or depressed and 52.6% (95%CI 51.2;54.1) frequently felt anxious or nervous; 43.5% (95%CI 41.8;45.3) reported the onset of sleep problems and 48.0% (95%CI 45.6;50.5) had a prior sleep problem that had become worse. Frequent sadness and nervousness, as well as change in sleep patterns were higher in young adults, women and those with a history of depression.


The high prevalence found indicates the need to guarantee the provision of services for mental health and quality of sleep that are adapted to the pandemic context.
