          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.

          Abstract

          【摘 要】儿童青少年过多使用屏幕媒体的情况非常普遍,对超重、肥胖及近视的风险产生不利影响。因此,有关视屏时间 干预的研究至关重要。本研究对国外以减少儿童青少年视屏时间为目的研究成果进行回顾分析,以总结在不同环境和策 略下实施干预研究的经验以及运动方案设置。分析发现,国外关于减少儿童青少年视屏时间的干预研究注重跨学科整合 研究,且设计严谨、科学。但也存在未对屏幕媒体类型、年龄、性别等变量进行差异性检验,以及缺少运动干预的综合评定 等方面的不足。中国研究者可从倡导多部门、跨领域的合作研究,重视 “学校-社区-家庭” 的联合干预研究,加强数据分析 过程的全面性等 3 个方面,制定科学合理的干预方案,减少儿童青少年视屏时间,促进其健康发展。
