Objective: To analyze the associations of physical activity and TV-viewing reported changes during the COVID-19 pandemic quarantine with mental health among Brazilian adults with and without depression.Methods: Data of 43,995 Brazilian adults from a cross-sectional, nationwide behavior research were used. Participants reported the frequency on loneliness, sadness (feel sad, crestfallen or depressed) and anxiety (feel worried, anxious or nervous) feelings during the pandemic period. Frequency and duration of physical activity as well as duration of TV-viewing before and during the pandemic period were also reported. We created four categories of reported changes in physical activity (1-consistently active, 2-become active, 3-become inactive or 4-consistently inactive) and TV-viewing (1-consistently high, 2-become low, 3-become high or 4-consistently high). Participants also reported previous diagnoses of depression [yes (PD) or no (nPD). Logistic regression models separating people with and without depression were created.Results: Compared to consistently active participants, to become inactive during the pandemic was associated with a higher odds for loneliness [nPD:OR:1.32 (95%CI,1.02-1.70); PD:2.22 (1.21-4.06)], sadness [nPD:1.34 (1.01-1.77); PD:2.88 (1.54-5.36)], and anxiety [nPD:1.71 (1.30-2.25); PD:2.55 (1.20-5.42)]. Also, people with depression and consistently physically inactive presented higher odds for loneliness and sadness. Compared to consistently low TV-viewing, participants that become with high TV-viewing showed higher odds for loneliness [nPD:1.59 (1.37-1.86)], sadness [nPD:1.68 (1.44-1.96); PD:1.61 (1.21 to 2.15)] and anxiety [nPD:1.73 (1.48-2.02); PD:1.58 (1.12-2.23)].Conclusions: Reported increases in physical inactivity and TV-viewing during the COVID-19 pandemic were associated with poorer mental health indicators. People with depression and consistently physically inactivity were more likely to present loneliness and sadness. [ABSTRACT FROM AUTHOR]

Objective: Depression is commonly associated to physical multimorbidity and there is an urgent need to identify modifiable risk factors. Physical activity (PA) is good for health, but the association between PA and multimorbidity with depressive symptoms is unclear. Thus, we investigated whether meeting weekly recommended PA guidelines influences the association between multimorbidity and depressive symptoms.Methods: Data were used from a national survey conducted in Brazil in 2013 with 60,202 adults (≥ 18 years). Information regarding depressive symptoms (PHQ-9), PA, and chronic disease was collected via interview-administered questionnaires. Data on covariates (age, educational status, employment status, tobacco smoking, alcohol consumption, and TV-viewing) were also assessed. Adjusted logistic regression models were used.Results: Overall, men and women with one or more chronic conditions who were inactive (engaging in <150 min PA per week) had higher odds of elevated depressive symptoms than active individuals with no chronic condition. However, only in men, physical inactivity interacts with heart disease (OR: 2.59; 95%CI: 1.10 to 6.09), cancer (OR: 21.54; 95%CI: 2.67 to 173.94) and chronic obstructive pulmonary disease (COPD) (OR: 8.26; 95%CI: 2.20 to 31.01) regarding elevated depressive symptoms.Conclusion: Our data suggest that engaging in weekly recommended PA targets may attenuate association of heart disease, cancer and COPD with depressive symptoms among men.
