ABSTRACT

OBJECTIVE: to evaluate the effects of intervention program strategies on the time spent on activities such as watching television, playing videogames, and using the computer among schoolchildren. SOURCES: a search for randomized controlled trials available in the literature was performed in the following electronic databases: PubMed, Lilacs, Embase, Scopus, Web of Science, and Cochrane Library using the following Keywords randomized controlled trial, intervention studies, sedentary lifestyle, screen time, and school. A summary measure based on the standardized mean difference was used with a 95% confidence interval. DATA SYNTHESIS: a total of 1,552 studies were identified, of which 16 were included in the meta-analysis. The interventions in the randomized controlled trials (n = 8,785) showed a significant effect in reducing screen time, with a standardized mean difference (random effect) of: -0.25 (-0.37, -0.13), p < 0.01. CONCLUSION: interventions have demonstrated the positive effects of the decrease of screen time among schoolchildren. .


OBJETIVO: avaliar os efeitos das estratégias dos programas de intervenção sobre o tempo dedicado a atividades como assistir à televisão, jogar videogame e usar computador em escolares. FONTE DOS DADOS: foi realizada busca de estudos controlados randomizados, disponíveis nas bases de dados eletrônicas PubMed, Lilacs, Embase, Scopus, Web of Science e Cochrane Library, com os descritores: randomized controlled trial, intervention studies, sedentary lifestyle, screen time e school. Medida de sumário baseada na diferença das médias padronizadas foi usada com intervalo de confiança de 95%. SÍNTESE DOS DADOS: foram identificados 1.552 estudos, dos quais 16 foram incluídos na metaanálise. As intervenções nos estudos controlados randomizados (n = 8.785) apresentaram efeito significativo na redução do tempo em frente à tela, com diferença das médias padronizadas (efeito randômico): -0,25 (-0,37; -0,13), p < 0,01. CONCLUSÃO: as intervenções mostraram efeitos positivos na redução do tempo em frente à tela em escolares. .
