Abstract:

The objective was to investigate the association between the time of excessive use of different screens, the quality of the diet in adolescents, and characteristics of the school environment. Adolescents30 state schools in Curitiba/PR, Brazil, reported screen time: television, video games and portables devices. Diet quality was assessed by the frequency of food consumption. The income of the school environment was takenthe Census. The built environment for physical activity investigated by systematic observation of the school environment. Multilevel Poisson Regression was employed to estimate associations with exposure variables. Among 1,200 adolescents, 50.9% male, 74.4% had excessive screen time. Excessive TV time (56.5%) was associated with worse diet quality. Excessive video game time (22.0%) was lower among females (PR 0.25; 95%CI 0.18;0.36), associated with poorer diet quality, lower school environment income, and worst classification of the built environment for physical activity. Excessive time on portable screens (53.2%) tended to increase with the income of the school environment. Excessive use of TV and portable screens was widely spread in adolescents, with different demographic and contextual variables associated according to the type of device used.
