Physical activity based screen time interventions for children and adolescents / 中国学校卫生

ABSTRACT

Abstract@#Excessive screen-media use among children and adolescents is highly prevalent which increases the risk of being overweight or obese, as well as developing myopia. Therefore, screen time interventions for children and adolescents is of great importance. This review presents a retrospective analysis of foreign studies aimed at reducing screen time for children and adolescents, and summarizes the experience of implementing intervention studies, strategies, and exercise programs in different settings. The findings revealed that foreign studies of screen time in children and adolescents rely on interdisciplinary integration, and the research design of such studies is rigorous and scientific. However, there are still some limitations: Research has failed to account for certain variables (screen media type, age, and gender), and comprehensive evaluations of exercise interventions are lacking. Chinese researchers can formulate scientific and reasonable intervention programs by focusing on the following three factors advocating multi-department and cross-domain,research cooperation; attaching importance to joint intervention studies based in schools, the community, and family; and strengthening the comprehensiveness of data analytic process, with the ultimate goal of reducing screen time for children and adolescents, as well as promoting their healthy development.
