Adelantado-Renau M, et al. - Researchers analyzed data from 58 cross-sectional studies included in this systematic review and meta-analysis, to evaluate specific academic performance areas in children and adolescents in relation to time spent on screen-based activities. They also assessed this link separately in these populations. These studies were identified from MEDLINE, Scopus, Web of Science, Cochrane Database of Systematic Reviews, and ERIC, explored from inception through September 2018. They found inverse link of television viewing with composite academic performance scores, language, and mathematics. An inverse association of video game playing with composite scores was also identified. In subgroup analyses, only children showed an inverse link of television viewing with language, whereas only adolescents demonstrated an inverse link of both television viewing and video game playing with composite scores. Individual analysis of each screen-based activity for its link with academic performance was recommended, especially it is meant for television viewing and video game playing, the activities seemed to be most negatively related to academic results. In order to enhance the academic performance of children and adolescents exposed to these activities, education and public health professionals are advised to take supervision and reduction into account.
