ABSTRACT
OBJECTIVE: Since COVID-19 pandemic, screen time (ST) seems to have increased among children and young people. There is controversy about its impact in the physical and mental well-being of children. The aim of this study was to analyse the possible influence of excessive ST on child health through a systematic review of the literature.
METHODS: Systematic review was done by two independent reviewers. We analysed the medical literature (MEDLINE data base) from 2017 to 2022. Data related to the effects of ST on childrenĀ“s health were analysed along with strategies that can mitigate those effects.
RESULTS: The search identified 3,151 articles, 37 finally selected as they fulfilled the demanded methodological quality criteria. Negative effects on children’s health such as obesity, linked to a sedentary lifestyle, sleep disorders or anxiety problems in adolescents were detected. However, a better development of language or memory functioning, when interactive media were used, have also been described. Educational measures have proven useful in controlling exposure time and reducing exposure-related negative effects.
CONCLUSIONS: Although high levels of ST could affect children`s health, we have recorded some positive effects that are enhanced when parents get involved in TV watching (co-viewing). Exposure time should be customized according to every child’s lifestyle.
