| Popis: | BACKGROUND Sedentary behaviors in adolescents are associated with using screen devices, analyzed as the total daily time in television viewing, using the computer and video game. However, an independent and clustered analysis of devices allows greater understanding of associations with physical inactivity domains and eating habits in adolescents. METHODS Sample of adolescents aged 10-17 years (N.=1011) from public and private schools, randomly selected. The use of screen devices was measured by hours per week spent in each device: TV, computer, videogames and mobile phone/tablet. Physical inactivity domains (school, leisure and sports), eating habits (weekly food consumption frequency) and socioeconomic status were assessed by questionnaire. RESULTS The prevalence of high use of mobile phone/tablet was 70% among adolescents, 63% showed high use of TV or computer and 24% reported high use of videogames. High use of videogames was greater among boys and high use of mobile phone/tablet was higher among girls. Significant associations of high use of TV (OR=1.43, 95% CI: 1.04-1.99), computer (OR=1.44, 95% CI: 1.03-2.02), videogames (OR=1.65, 95% CI: 1.13-2.69) and consumption of snacks were observed. High use of computer was associated with fried foods consumption (OR=1.32, 95% CI: 1.01-1.75) and physical inactivity (OR=1.41, 95% CI: 1.03-1.95). Mobile phone was associated with consumption of sweets (OR=1.33, 95% CI: 1.00-1.80). Cluster using screen devices showed associations with high consumption of snacks, fried foods and sweets, even after controlling for confounding variables. CONCLUSIONS The high use of screen devices was associated with high consumption of snacks, fried foods, sweets and physical inactivity in adolescents. |
