Abstract Objectives To assess alcohol use and perceived change in alcohol consumption (before and during the pandemic) in Brazilians during the COVID-19 pandemic, their correlates, and their associations with depressive, anxiety and co-occurring depressive and anxiety symptoms (D&A). Methods This is a cross-sectional study comprising 992 individuals in self-isolation. A self-report questionnaire was used to assess whether participants were drinking during self-isolation and whether they changed their drinking behavior (drinking less, more, or no change) from before to during the pandemic. D&A symptoms were assessed using the Beck Depression and Anxiety Inventories (BDI and BAI). Results A total of 68.5% of participants reported alcohol consumption during the pandemic, and 22.7% of these reported increased alcohol use. Smoking was positively associated with alcohol consumption during the pandemic. Alcohol consumption was associated with anxiety (OR = 1.40, 95%CI 1.06-1.85, p < 0.01) and D&A (OR = 1.38, 95%CI 1.02-1.87, p = 0.033) symptoms. Conclusions Drinking during self-isolation was prevalent and was associated with risk factors for alcohol use disorders. The long-term effects of high drinking rates and increased consumption should be proactively monitored and assessed.

Objective: To evaluate the associations of moderate to vigorous physical activity (MVPA), vigorous physical activity (VPA), moderate physical activity (MPA), and sedentary behavior (SB) with depressive, anxiety, and co-occurring depressive and anxiety symptoms (D&amp;A) during the COVID-19 pandemic in Brazil.Methods: Cross-sectional online survey in self-isolating people. Self-reported MVPA, VPA, MPA, and SB (exposures), and depressive and anxiety symptoms (Beck Depression and Anxiety Inventories [BDI and BAI]) were collected. Associations of MVPA, VPA, MPA, and SB with prevalent depressive (BDI&gt;9), anxiety (BAI&gt;7), and D&amp;A (BDI&gt;9+BAI&gt;7) symptoms were investigated using logistic regressions, presented as odds ratio (OR) and 95% confidence interval (95%CI). Linear regressions were performed testing associations with symptom severity. Models were adjusted for confounding factors. Results: Participants (n=937, females=72.3%) performing ≥30min/day MVPA or ≥15min/day VPA had lower odds of prevalent depressive (ORMVPA=0.71, 95%CI=0.53-0.96; ORVPA=0.60, 95%CI=0.43-0.82), anxiety (ORMVPA=0.71, 95%CI=0.54-0.96; ORVPA=0.70, 95%CI=0.51-0.96), and co-occurring D&amp;A symptoms (ORMVPA=0.71, 95%CI=0.52-0.96; ORVPA=0.59, 95%CI=0.41-0.83). People spending ≥10h/day sedentary were more likely to have depressive symptoms (OR=1.39,95%CI=1.02-1.90). Each hour spent sedentary corresponded to 0.22 (95%CI=0.10-0.33) points and 0.16 (95%CI=0.02-0.31) points higher on the BDI and BAI, respectively.Conclusion: Higher MVPA and VPA levels are associated with lower odds of depressive, anxiety and D&amp;A symptoms. Higher SB is associated with higher odds of depressive symptoms.
