|Popis||Background This study examined the associations of Internet and computer screen time with school difficulties and the role of sleep quality and soft and energy drinks consumption. Methods We used data from the cross-sectional Health Behaviour in School-aged Children study collected in 2014 among Slovak adolescents (aged 11.0 to 15.9 years, N = 7595, 48.1% boys). We examined the interrelations between time spent with on digital devices (time spent playing digital games or Internet use), sleeping quality (sleeping shortage, sleeping difficulties), soft/energy drinks consumption and school problems (low academic achievement, disliking school, being pressured by schoolwork and truancy), using structural equation modeling. Results Results showed that the more time adolescents spent on digital devices during leisure time, the more school problems they had. This association was mediated by a higher consumption of soft or energy drinks and a lower quality of sleeping. The direct effect of time spent on digital devices on school problems and its indirect effect via sleeping quality were relatively small, compared with the indirect effect of time spent on digital devices via soft/energy drinks consumption as well as sleeping quality. Conclusions Time spent on digital devices is associated with school problems, with sleeping and soft/energy drinks consumption playing a substantial role in this association.|
