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., Competing Interests: Declaration of Competing Interest The authors declare that they have no conflict of interest., (Copyright © 2020 Elsevier Inc.

Objective: To analyze the association between four key different physical activity (PA) domains and depressive symptoms among Brazilian adults., Methods: Data from the Brazilian National Health Survey (n = 60,202; ≥18 years) were used. PA across four different domains (leisure, transport, occupational and household) was collected through specific questionnaires. The cutoff point adopted in each domain was 150 min/week. Depression was evaluated through the Patient Health Questionnaire-9. Multivariable adjusted linear and logistic regression models were applied., Results: Leisure PA was associated with lower depressive symptoms [β: -0.008 (95% CI: -0.010 to -0.005); OR: 0.69 (95% CI: 0.59 to 0.81)]. Transport PA was also associated with lower depressive symptoms among older adults [β -0.008 (-0.012 to -0.003); OR: 0.70 (95% CI: 0.53-0.94)] but not middle-aged adults. On the other hand, occupational PA [β: 0.003 (95% CI: 0.002 to 0.005); OR: 1.62 (95% CI: 1.38 to 1.91)] and household PA [β: 0.009 (95% CI: 0.006 to 0.012); OR: 1.57 (95% CI: 1.37 to 1.79)] were associated with higher depressive symptoms., Conclusion: The association between PA and depression symptoms varies according to the domains of PA and some appear independent from each other. While leisure PA is associated with fewer depressive symptoms; occupational and household PA appear to be associated with an increased depression risk., Competing Interests: Declaration of competing interest The authors state that there is no conflict of interest., (Copyright © 2020 Elsevier Inc.

Objective: To investigate the potential influence of physical, psychological, and lifestyle factors on the association between TV-viewing and depressive symptoms among Brazilian adults., Methods: We used cross-sectional data from the Brazilian National Survey, conducted in 2013 with 60,202 adults (≥18 years). Information regarding exposure (TV-viewing), potential influencing factors (multimorbidity, mobility, self-rated health, tobacco use, alcohol consumption, sugar consumption, and physical activity) as well as elevated depressive symptoms (through PHQ-9 - score > 9) (outcome) was collected via interview-administered questionnaires. Data on covariates were self-reported. Body mass index was estimated through the assessment of body mass and stature. Mediation models were estimated through the Karlson-Holm-Breen method., Results: Individuals who reported >5 h/d of TV viewing showed a higher prevalence of depressive symptoms than those with <5 h/d of TV viewing [8.1%(99%CI:7.6%-8.6%) vs 14.2%(99%CI:12.2%-16.6%)]. The association between TV-viewing and depressive symptoms was influenced by tobacco use (Overall: 7.22%; men: 4.46%, women: 8.59%), physical activity (men: 3.99%, women: 2.28%), mobility (overall: 11.31%, men: 10.85%, women: 11.03%), and multimorbidity (overall: 9.11%, men: 11.6%, women: 6.03%). Poor self-rated health influenced the association between TV-viewing and elevated depressive symptoms only among men (15.55%). Similarly, the association between >4 h/d of TV viewing and depressive symptoms was influenced by tobacco use (men: 6.8%, women: 11.7%), physical activity for women (5.5%), self-rated health for men (14.7%), mobility (men: 8.7%, women: 17.0%), and multimorbidity (men: 9.6%, women: 12.3%)., Conclusions: Tobacco use, physical activity, mobility, multimorbidity, and self-rated health (men) mediate the relationship between high TV-viewing and elevated depressive symptoms. Longitudinal research is required to confirm/refute our data which may also be useful to contribute to public health interventions., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Background: Both physical activity (PA) and TV-viewing are associated with depressive symptoms, but the combined association with depressive symptoms is unclear. Therefore, our aim was to analyze the joint association of PA and TV-viewing with depressive symptoms among a large cohort of adults., Methods: We used data from the Brazilian National Survey, conducted in 2013 with 59,401 adults [≥18 years (34,282 women)]. Information regarding exposures (TV-viewing and leisure PA), outcome (depressive symptoms) and covariates (chronological age, race, educational status, employment status, tobacco smoking, alcohol consumption) were self-reported. Body mass index was estimated through the assessment of body mass and stature. Logistic regression models were used., Results: Engaging in >5 hours of TV viewing was associated with elevated depressive symptoms [13.1% (CI95%: 11.6%-14.7%) vs. 7.4% (95%CI:7.0%-7.8%)]. However, this association was nullified when people met guidelines and engaged in >150 min of PA per week. Specifically, among men [Active: OR = 1.16 (95%CI: 0.58-2.32) vs. Inactive: OR = 3.63 (95%CI: 2.43-5.42)] and women [Active: OR=1.30 (95%CI: 0.80-2.11) vs. Inactive: OR = 1.84 (95%CI: 1.43-2.36)]., Conclusion: Whilst TV viewing is associated with increased depressive symptoms, meeting recommended physical activity levels reduces the association between TV-viewing and depressive symptoms., (Copyright © 2019 Elsevier B.V.

To examine the theoretical substitutions of screen exposure, non-screen sitting time, moderate and vigorous physical activity with depressive and anxiety symptoms in South American adults during the COVID-19 pandemic. A cross-sectional study during the first months of the COVID-19 pandemic with data from 1981 adults from Chile, Argentina, and Brazil. Depressive and anxiety symptoms were assessed using the Beck Depression and Anxiety Inventories. Participants also reported physical activity, sitting time, screen exposure, sociodemographic, and tobacco use data. Isotemporal substitution models were created using multivariable linear regression methods. Vigorous physical activity, moderate physical activity, and screen exposure were independently associated with depression and anxiety symptoms. In adjusted isotemporal substitution models, replacing 10 min/day of either screen exposure or non-screen sitting time with any intensity of physical activity was associated with lower levels of depressive symptoms. Improvements in anxiety symptoms were found when reallocating either screen exposure or non-screen sitting time to moderate physical activity. Furthermore, replacing 10 min/day of screen exposure with non-screen sitting time was beneficially associated with anxiety (B = − 0.033; 95 % CI = − 0.059, − 0.006) and depression (B = − 0.026; 95 % CI = − 0.050, − 0.002). Replacement of screen exposure with any intensity of physical activity or non-screen sitting time could improve mental health symptoms. Strategies aiming to reduce depressive and anxiety symptoms highlight physical activity promotion. However, future interventions should explore specific sedentary behaviors as some will relate positively while others negatively. [ABSTRACT FROM AUTHOR]

Our aim was to test the potential moderating role of occupation type in the association between the domains of physical activity and depressive symptoms. We used data of 51,895 adults (44.8% women, 40.7 ± 13.3 years), currently employed, from the 2019 Brazilian National Health Survey. Depressive symptoms were assessed using the Patient Health Questionnaire-9 (PHQ-9). Self-reported physical activity (min/week) was assessed in four domains (i.e., leisure-time, transportation, occupational, and household). Type of occupation was characterized into five categories according to the International Standard Classification of Occupations: 1) Managers/qualified professionals, 2) Technicians/associate professionals, 3) Clerks/service workers, 4) Qualified manual workers, 5) Elementary manual workers. Age, ethnicity, educational level, income, and TV-viewing were used as covariates. Poisson regression was used for the analysis of association and moderation, through the inclusion of interaction terms. In the whole sample, leisure-time physical activity was associated with lower depressive symptoms, while transportation, occupational and household physical activity were associated with higher depressive symptoms. Type of occupation modified the association between leisure-time physical activity and depressive symptoms. That is, compared to managers/qualified professionals, leisure-time physical activity had larger associations with increased depressive symptoms in technicians/associate professionals (considering an increase of 100 min/wk of physical activity: unstandardized coefficient [ B ]:0.073, 95%CI:0.024; 0.121), qualified (B :0.067, 95%CI:0.025; 0.110) and elementary (B :0.065, 95%CI:0.016; 0.115) manual workers than among managers/qualified professionals. Stratified analyzes by occupation suggested that leisure-time physical activity was associated with lower depressive symptoms especially among managers/qualified professionals, while household physical activity and occupational physical activity were consistently associated with higher depressive symptoms across the different occupations. Transportation physical activity was associated with elevated depressive symptoms among clerks/service workers and qualified manual workers. The association between the domains of physical activity and depressive symptoms is dependent on the type of occupation. Future research exploring the association between domain-based physical activity and depression should account for the type of occupation. • Leisure-time physical activity was associated with lower depressive symptoms especially among managers/qualified professionals. • Household and occupational physical activity were consistently associated with higher depressive symptoms across the different occupations. • Transport physical activity was associated with elevated depressive symptoms among clerks/service workers and qualified manual workers.

Our aim was to analyze the association between different social contexts of physical activity (PA) and depressive symptoms. Data from the Brazilian National Health Survey (PNS) (n = 59,722; ≥18 years) were used. The social context of leisure-time PA [classified according to the higher probability of being practiced in group (group PA) or individually (individual PA)] and total PA time were self-reported. Depressive symptoms were evaluated through the Patient Health Questionnaire-9. Chronological age, ethnicity, educational status, employment status, tobacco smoking, alcohol ingestion, and soft drink consumption were co-variables. Logistic regression models were applied for association analyses. Among men, individual and group PA were associated with lower depressive symptoms compared with the no PA group among men [Individual: OR:0.59 (95%CI:0.40 to 0.86); Group: OR:0.42 (95%CI:0.29 to 0.59)]. Sensitivity analysis revealed that men involved in group PA were 40% [OR:0.60 (95%CI:0.38 to 0.94)] less likely to present elevated depressive symptoms when compared with individual PA. In females, no differences in depressive symptoms were observed comparing individual PA [OR:0.89 (95%CI:0.71 to 1.11)] and group PA [OR:0.86 (95%CI:0.54 to 1.37)] with the no PA group. Activities that are more likely to be a group PA demonstrated a stronger association with low depressive symptoms among men, but not women. • Both contexts of leisure-time physical activity are associated with reduced depressive symptoms, especially among men. • Among men, activities that are more likely to be practiced in group are strongly associated with lower depressive symptoms. • Interventions should focus on the increase of physical activity especially through group-based physical activity practice.

Objectives: To investigate the association between sedentary time (ST) patterns and depressive symptoms, and whether moderate-to-vigorous physical activity (MVPA) can moderate this association. Methods: This cross-sectional study included a representative sample of 243 adults (mean age 41.8616.7 years, 56.4% women) from a city in Southeast Brazil. Depressive symptoms were estimated through the Hospital Anxiety and Depression Scale (HADS). ST patterns (i.e., number of breaks, mean length of sedentary bouts, and number of long sedentary bouts), total ST, and MVPA were assessed using accelerometers. Results: Poisson regression models revealed associations of total ST (b = 0.063; 95%CI 0.011 to 0.116) and number of long bouts (0.108; 0.047 to 0.171) with depressive symptoms among men. MVPA moderated the associations of breaks and longer bouts of ST with depressive symptoms, with an increase of one break/hour, the increase of one long bout, and a decrease of 1 minute in mean bout length being associated with a reduction of 0.211 and increases of 0.081 and 0.166, respectively, in the number of depressive symptoms among men with physical inactivity (breaks = -0.211; -0.360 to -0.063; mean bout length = 0.081; 0.003 to 0.158; number of long bouts = 0.166; 0.090 to 0.242). Conclusions: Interventions that encourage breaking up ST should be helpful to reduce depressive symptoms among people with physical inactivity. [ABSTRACT FROM AUTHOR]

Background: Our aim was to analyze the associations between multiple lifestyle behaviors and depressive symptoms.Methods: We included 4,725 adults (18-59y), that provided data in routine health evaluations of a hospital in Brazil, followed for a mean period of 3.1 ± 1.6 years. Physical activity, alcohol consumption (measured using Alcohol Use Disorders Identification Test) and tobacco smoking were categorized as: (1) absence of the behavior (inactivity i.e. not complying with 150 min of moderate-to-vigorous PA/week, not smoking, no risky drinking, i.e. AUDIT<5) during baseline and follow-up; (2) Absence during baseline and presence during follow-up; (3) Presence during baseline and absence during follow-up; (4) Presence during both time points. Depressive symptoms were measured with the Beck Inventory was adopted to analyze patterns of depressive symptoms over time (as exposure). C-reactive protein [HS-CRP]) was assessed and its role in the association was tested. Incidence indicators of behaviors and depressive symptoms were created and used as outcomes. We used crude and adjusted Poisson regression analysis.Results: Fully adjusted models revealed that persistently physical inactive participants (RR:1.71;95%CI:1.33-2.21), those who became physically inactive (1.68;1.19-2.26), with consistently risky drinking (1.62;1.15-2.30), and who became risky drinkers (1.62;1.15-2.30) had higher risk for incidence of elevated depressive symptoms. Vice versa participants with incidence of depressive symptoms over time presented higher risk for physical inactivity (1.44;1.11-1.87) and risky drinking (1.65;1.16-2.34) incidence. HS-CRP did not influence the associations.Limitations: Self-reported physical activity, binary tobacco smoking, and non-probabilistic sampling.Conclusions: There is a prospective relationship between elevated depressive symptoms and adverse lifestyle behaviors.

Objective: Our aim was to analyze the association between sugar-sweetened beverage consumption and depressive symptoms, as well as the extent to which TV viewing and physical activity moderate this association. Methods: We used cross-sectional data from the 2013 Brazilian National Survey (Pesquisa Nacional de Sau'de) of 59,402 adults (33,482 women, mean age = 42.9 years, 95%CI 42.7-43.2 years). Depressive symptoms (Patient Health Questionnaire-9), physical activity, TV viewing, and sugarsweetened beverage consumption, as well as potential confounders (chronological age, ethnicity, consumption of candy/sweets and fruit, multimorbidity, education, and employment status) were selfreported. Poisson regression models were used for association analyses. Results: The consumption of 16 or more glasses/week of sugar-sweetened beverages was associated with higher levels of severe depressive symptoms among women compared to no consumption (prevalence ratio [PR] 1.71 [95%CI 1.38-2.11]). Consistent interactions were observed between 1-5 glasses and TV viewing (PR 2.09 [95%CI 1.06-4.12]) and between 11-15 glasses and TV viewing (PR 2.90 [95%CI 1.29-6.50]) among men compared to no consumption, given that the cooccurrence of sugar-sweetened beverage consumption and elevated TV viewing was associated with higher odds of severe depressive symptoms. Sugar-sweetened beverage consumption did not interact with physical activity, only presenting an independent association. Conclusion: Sugar-sweetened beverage consumption was independently associated with severe depressive symptoms among women and interacted with TV viewing, but not with physical activity among men.
