移动通讯技术对儿童青少年肥胖干预效果的Meta分析

Meta-analysis of effects on mobile health intervention in children and adolescents obesity

目的评价移动医疗在儿童青少年肥胖干预中对蔬菜与水果摄入量,视屏时间,体质量指数(BMI),BMI Z分及腰围的干预效果,为移动医疗应用于儿童青少年肥胖的干预研究提供循证依据。方法系统检索PubMed、Embase、Cochrane Library、中国期刊全文数据库(CNKI)、万方等数据库,组合关键词"prevention""children""adolescents""obesity""weight loss""m-Health""mobile phone""mobile application""mobile technology""cell phone""smartphone""mobile apps""儿童""青少年""肥胖""移动医疗""手机""手机应用"为中英文检索词,收集2018年12月前发表的关于移动医疗对儿童青少年肥胖干预效果的研究文献。采用Stata 13.0软件进行Meta分析。结果共纳入15篇相关文献,移动医疗干预对儿童青少年的蔬菜与水果摄入量、视屏时间有影响,标准化均数差(SMD)及95%CI分别为0.54(0.27~0.81),-0.32(-0.47^-0.18),但对BMI,BMI Z分及腰围的改变尚未见到明显作用。结论移动医疗对儿童青少年肥胖干预效果的研究还需更多长时间随访及更大样本量的研究来予以明确。

Objective To evaluate effects of mobile health intervention on vegetables and fruits intakes,screen time,body mass index,BMI Z-score and waist circumference in children and adolescents.Methods The literature search was performed to find articles published up to December 2018 in the databases:PubMed,Embase,Cochrane Library,CNKI,Wan-fang.The articles focusing on the keywords of"prevention""children""adolescents""obesity""weight loss""m-Health""mobile phone""mobile application""mobile techonology""cell phone""smartphone""mobile apps"for the delivery of children and adolescents obesity interventions were included.Stata 13.0 software was used for Meta-analysis.Results A total of 15 studies were included,and mobile health had an effect on the vegetables and fruits intakes and screen time for children and adolescents.Mobile health was more effective in the intervention participants compared to controls,the standardized mean difference(SMD)and 95%CI were 0.54(95%CI=0.27-0.81)and-0.32(95%CI=-0.47--0.18),respectively.However,no statistical differences in the BMI,BMI Zscore and waist circumference were found between intervention and control groups.Conclusion The effect of mobile health intervention on obesity in children and adolescents needs more long-term follow-up and larger sample size studies to clarify.
