Background: Our aim was to examine associations between depression and time spent in TV viewing in a representative sample of Brazilian adults.
Methods: Data from the Brazilian National Health Survey (Pesquisa Nacional de Saude -PNS in Portuguese) (n = 60,202; = 18 years) were used. Time spent TV viewing (h/day) was elicited via interview. Depression was evaluated through the Patient Health Questionnaire-9. Chronological age, educational status, employment status, alcohol use, tobacco smoking and body mass index were covariates. Descriptive statistics (mean and 95% confidence interval) and adjusted logistic regression models were applied.
Results: Five or more hours as well as less than 1 h of TV viewing was associated with increased depression (men: < 1 h OR = 1.89, 95% CI= 1.40-2.54; >= 5 h OR = 2.69, 95% CI= 1.88-3.83; women: < 1 h OR = 1.50, 95% CI= 1.25-1.81; >= 5 h OR= 1.65, 95% CI= 1.35-2.03) when compared to 2-2.99 h of TV viewing.
Conclusion: More than 5 h/day seems to be associated with a higher risk for depression among Brazilian adults (except for older adults). Less than 1 h TV viewing might be a measure-of-proxy for a lower socio-economic status, which is a known risk factor for depression.
