Abstract
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 asso ciation 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 symp toms) 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 phy sical activity levels reduces the association between TV-viewing and depressive symptoms.
