Prevalência de tempo excessivo de tela e fatores associados em adolescentes

Abstract

Objective:To determine the prevalence of excessive screen time and to analyze associated factors among adolescents.Methods:This was a cross-sectional school-based epidemiological study with 2874 high school adolescents with age 14-19 years (57.8% female) from public and private schools in the city of João Pessoa, PB, Northeast Brazil. Excessive screen time was defined as watching television and playing video games or using the computer for more than 2 h/day. The associated factors analyzed were: sociodemographic (gender, age, economic class, and skin color), physical activity and nutritional status of adolescents.Results:The prevalence of excessive screen time was 79.5% (95%CI 78.1-81.1) and it was higher in males (84.3%) compared to females (76.1%; p<0.001). In multivariate analysis, adolescent males, those aged 14-15 year old and the highest economic class had higher chances of exposure to excessive screen time. The level of physical activity and nutritional status of adolescents were not associated with excessive screen time.Conclusions:The prevalence of excessive screen time was high and varied according to sociodemographic characteristics of adolescents. It is necessary to develop interventions to reduce the excessive screen time among adolescents, particularly in subgroups with higher exposure.

Factors associated with screen time in Iranian children and adolescents: The CASPIAN-IV study

“…Data presented no significant association between weight and screen time,[45] which was consistent with our results. While other studies showed that obesity was positively associate with increase of screen time,[62339] in our study students with overweight and obesity significantly had higher risk of increasing time spent watching TV.…”

“…[23] Data showed that high socioeconomic status (SES),[4] unhealthy eating habits,[5] depression, and mental problems[24] are related to screen time.…”

Anthropometry and lifestyle of children and adolescent in inland of Northeastern Brazil

“…Dias and collaborators 12 also observed an association between excess weight in adolescence and insufficiently active behavior. On the other hand, Aires and collaborators 25 found no association between excess weight and inactive behavior and Lucena and collaborators 26 also found no association with sedentary behavior. The differences of the results presented by the studies may be explained by methodological differences, as described in a systematic review that evaluated the relationship between sedentary behavior and excess weight 27 .…”

Entre Pais e Filhos: Encontros com a Cultura dos Videogames

“…Além disso, há estudos apontando os videogames como ferramentas interessantes para a promoção saúde (Dias, Domingues, Tibes, Zem-Mascarenhas & Fonseca, 2018;Baum & Maraschin, 2016Meneghini, Barbosa, Mello, Bonetti, & Guimarães, 2016;Ramos & Segundo, 2018;Vojciechowski et al, 2017;Ramos, Fronza & Cardoso, 2018;Martel, Colussi & Marchi, 2016;Natal et al, 2016). Por outro lado, estudos evidenciam que o uso recorrente de videogames pode favorecer a) relações de adição e dependência (Abreu, Karam, Góes & Spritzer, 2008;Suzuki, Matias, Silva & Oliveira, 2009;Salas-Blas, Merino-Soto, Chóliz & Marco, 2017;, b) comportamentos agressivos ou violentos (Alves, 2002(Alves, , 2004, c) isolamento social (Kenski, 1995;Paiva & Silva Costa, 2015) e d) condutas sedentárias (Dumith et at., 2010;Frutuoso, Bismarck-Nasr & Gambardella, 2011;Sousa & Silva, 2017;Ferrari, Araújo, Oliveira, Matsudo & Fisberg, 2015;Lucena, Cheng, Cavalcante, Silva & Farias Júnior, 2015;Ferreira, Rombaldi, Ricardo, Hallal & Azevedo, 2016).…”
