Resumo

Introdução: O uso de smartphones e tablets tem aumentado consideravelmente entre as crianças nos últimos anos e tem sido associado a diversos desfechos de saúde, incluindo o excesso de peso.

Objectivo: Realizar uma revisão sistemática e uma meta-análise da associação entre o uso de smartphones e tablets e o excesso de peso e obesidade em crianças dos 5 aos 10 anos de idade.

Metodologia: Esta revisão sistemática seguiu as diretrizes PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) e incluiu estudos observacionais que cumpriam os critérios de elegibilidade PECO (população, exposição e desfecho). As pesquisas foram realizadas nas bases de dados PubMed, Embase, Web of Science, ScienceDirect, Scopus e LILACS. A qualidade metodológica e o risco de viés foram avaliados através da Escala de Newcastle-Ottawa e da ferramenta AXIS. As meta-análises foram realizadas através do método da variância inversa com modelos de efeitos fixos e aleatórios.

Resultados: Foram identificados um total de 1.883 registos, e 18 estudos foram incluídos na revisão sistemática, dos quais 12 foram incluídos na meta-análise. O uso de smartphones e tablets foi positivamente associado ao excesso de peso e à obesidade nas crianças (OR = 1,31; IC 95% 1,24–1,39). Uma análise de sensibilidade que incluiu estudos com medidas de efeito comparáveis ​​mostrou uma associação ainda mais forte (OR = 1,88; IC 95% 1,54–2,30).

Discussão: Os resultados são consistentes com estudos anteriores que sugerem que uma maior exposição a dispositivos com ecrã pode estar relacionada com o excesso de peso durante a infância.

Conclusões: O uso mais frequente de smartphones e tablets esteve associado a maiores probabilidades de excesso de peso e obesidade nas crianças, o que realça a importância da monitorização dos comportamentos relacionados com o uso dos ecrãs durante a infância.
