The selection, extraction and synthesis ofthe data were conducted according to PRISMA guidelines. The search was carried out in the electronic databases Medline(PubMed), PsycINFO (American Psychological Association), Scopus and Web of Science (WOS). Of the 597 articles initially identified, 13 met the inclusion criteria. The risk of bias of the articles selected was evaluated using a specific scalecreated for this purpose. The results found indicate that excessive use of screens is associated with a negative impact onthe duration and quality of sleep-in preschoolers, and this worsening of sleep in infancy is related with a greater probabilityof the appearance of internalizing and externalizing behavioral problems and certain cognitive problems. The results alsosuggest that sleep could play a mediating or moderating role as a bioregulatory system that attenuates or increases theonset of behavioral and cognitive difficulties in those children most exposed to digital devices.
