Abstract:
Adolescents from 30 state schools in Curitiba, State of Paraná, reported total screen time, namely television, video games and laptops. Diet quality was assessed by the frequency of food consumption. The income of the school environment was taken from the Census. The built environment for physical activity was investigated by systematic observation of the school surroundings. Multilevel Poisson Regression was used to estimate associations with the exposure variables. Among 1,200 adolescents, 50.9% being male, and 74.4% were found to be exposed to excessive screen time. Excessive TV screen time (56.5%) was associated with poor diet quality. Excessive video game time (22.0%) was lower among females (PR 0.25; 95%CI 0.18;0.36), associated with poor diet quality, lower school environment income, and the worst classification of the built environment for physical activity. Excessive use of portable screens (53.2%) tended to increase with the income of the school environment. Excessive use of TV and laptops was widespread among adolescents, with different demographic and contextual variables associated according to the type of device used.
