Early Psychological Impact of the COVID-19 Pandemic in Brazil: A National Survey.

High prevalence of depression (61.3%), anxiety (44.2%), stress (50.8%), and psychological impact (54.9%) due to the isolation experienced from the pandemic was found. Younger individuals (OR = 1.58-3.58), those that felt unsafe (OR = 1.75-2.92), with a previous diagnosis of mental health (OR = 1.72-2.64) and/or had general health problems before the pandemic (OR = 1.17-1.51), who noticed changes in their mental state due to the pandemic context (OR = 2.53-9.07), and excessively exposed to the news (OR = 1.19-2.18) were at increased risk of developing symptoms. Women (OR = 1.35-1.65) and those with lower economic status (OR = 1.38-2.69) were more likely to develop psychological symptoms. Lower educational levels increased the likelihood of depressive (OR = 1.03-1.34) and intrusive symptoms (OR = 1.09-1.51). Conclusions: The pandemic and related factors can have a high impact on the mental health of the population. Demographic characteristics can influence the occurrence of psychological symptoms.
