摘　　要：目的:采用Meta分析综合相关随机对照试验(RCT),探讨智能手机技术对学龄前儿童、学龄儿童及青少年静坐行为与屏幕时间可能存在的干预效果。方法:通过检索PubMed、Web of Science、EBSCO和中国知网(核心期刊)数据库,获取智能手机技术干预儿童青少年静坐行为及屏幕时间的RCT;采用Cochrane偏倚风险评估工具进行文献质量评价,STATA 15.1软件进行合并效应量分析和亚组分析。结果:共纳入文献15篇,其中应用程序(App)干预3篇、短信(SMS)干预10篇、App+SMS干预2篇。Meta分析发现,与对照组相比,智能手机技术对静坐行为时间的减少无显著干预效果(SMD=0.04;95%CI:-0.06,0.14;P=0.41),但可显著降低屏幕时间(SMD=-0.24;95%CI:-0.35,-0.13;P<0.001)。亚组分析发现,基于SMS技术、SMS+其他、>12岁、>12周、频率<3次/周均可显著降低屏幕时间,但各亚组均未见对静坐行为时间具有显著减少作用。结论:基于智能手机技术干预可有效改善儿童青少年屏幕时间,但对静坐行为无明显干预效果;基于SMS技术干预能有效改善屏幕时间;智能手机技术改善屏幕时间的作用对青少年较适宜,长周期与低频率干预更能体现干预效果。Objective:Meta-analysis was used to to determine the effect of smartphone technology on sedentary behavior and screentime of preschoolers,school-age children and adolescents.Methods:Four electronic databases,PubMed,Web of Science,EBSCO and the CNKI were searched for randomized controlled trial,and smartphone technology intervention in sedentary behavior of children and adolescents were obtained.Risk of bias was assessed by the Cochrane collaboration tool,and the Meta-analysis was performed by using STATA 15.1.Results:A total of 15 studies were included,among them 3 studies for APP based intervention,10 studies for SMS based intervention and 2 studies for App+SMS intervention.Meta-analysis results showed that comparing with the control group,smartphone technology had no significant effect on sedentary behavior(SMD=0.04;95%CI:-0.06,0.14;P=0.41),but significantly reduced screen time(SMD=-0.24;95%CI:-0.35,-0.13;P<0.001).Subgroup analysis found that SMS based intervention,SMS+Other,age“>12 years”,“>12 weeks”and intervention frequency“<3 times/week”could significantly reduce the screen time.But there was no significant decrease in sedentary behavior time in all subgroups.Conclusions:Smartphone technology intervention can effectively improve the screen time of children and adolescents,but it has no effect on sedentary behavior.SMS based intervention can effectively improve screentime.The effect of smartphone technology on improving screen time is suitable for adolescents,and long-term intervention can better reflect the effect of improvement.
