Our work as part of HBSC study resulted in recently published paper “Do sleeping habits mediate the association between time spent on digital devices and school problems in adolescence?” by Daniela Husarova, Lukas Blinka, Andrea Madarasova Geckova, Jan Sirucek, Jitse P. van Dijk, Sijmen  A. Reijneveld in European Journal of Public Health.

We found 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.
