High-dose electronic media use in five-year-olds and its association with their psychosocial symptoms: a cohort study.

Increased screen time has multiple risks for children's psychosocial well-being. These risk factors seem to be significant in the long term, and are related to problems in children's socio-emotional development later on. Health professionals and paediatricians have an important role as communicators of the current research results on the safe usage time of e-media for families, and enhancing parents' skills as regulators of children's safe e-media use. More research is needed on the family conditions of high-dose e-media users.
