背景：肥胖和缺乏体育活动是许多危及生命的疾病的主要健康危险因素，如心血管疾病、2型糖尿病和癌症。由于对尖端和更有效的干预措施的需求，使用移动应用程序干预措施促进儿童和成人的减肥和加强身体活动是令人着迷的。之前发表的研究已经研究了不同类型的基于技术的干预措施及其对减肥和增加体力活动的影响，但关于仅仅一个手机应用程序对减肥和增加体力活动的影响的证据仍然缺乏。目的：本研究的主要目的是评估手机应用程序干预在儿童和成人中减轻体重和增加身体活动的功效。方法：检索2000年1月1日至2019年4月30日期间发表的无语言限制的PubMed、谷歌Scholar、Scopus、EMBASE和Web of Science电子数据库。两位专家独立筛选了所有的标题和摘要，以找到最合适的研究。被纳入的研究必须是随机对照试验或病例对照研究，评估手机应用程序干预与体重减轻和身体活动的结果。使用Cochrane协作偏倚风险工具检查发表偏倚风险。结果：本荟萃分析共纳入了12项涉及手机应用干预的研究。与对照组相比，使用手机应用程序与体重（-1.07 kg, 95% CI -1.92至-0.21，P= 0.01）和体重指数（-0.45 kg/m2, 95% CI -0.78至-0.12，P= 0.008）的显著变化相关。此外，观察到身体活动没有显著增加（0.17,95% CI -2.21至2.55，P= 0.88）。结论：本研究的发现证明了使用手机应用程序干预减肥的前景和新兴功效。未来的研究需要在更大的样本中探索移动应用干预的长期功效。
Background: Obesity and lack of physical activity are major health risk factors for many life-threatening diseases, such as cardiovascular diseases, type 2 diabetes, and cancer. The use of mobile app interventions to promote weight loss and boost physical activity among children and adults is fascinating owing to the demand for cutting-edge and more efficient interventions. Previously published studies have examined different types of technology-based interventions and their impact on weight loss and increase in physical activity, but evidence regarding the impact of only a mobile phone app on weight loss and increase in physical activity is still lacking.Objective: The main objective of this study was to assess the efficacy of a mobile phone app intervention for reducing body weight and increasing physical activity among children and adults.Methods: PubMed, Google Scholar, Scopus, EMBASE, and the Web of Science electronic databases were searched for studies published between January 1, 2000, and April 30, 2019, without language restrictions. Two experts independently screened all the titles and abstracts to find the most appropriate studies. To be included, studies had to be either a randomized controlled trial or a case-control study that assessed a mobile phone app intervention with body weight loss and physical activity outcomes. The Cochrane Collaboration Risk of Bias tool was used to examine the risk of publication bias.Results: A total of 12 studies involving a mobile phone app intervention were included in this meta-analysis. Compared with the control group, the use of a mobile phone app was associated with significant changes in body weight (-1.07 kg, 95% CI -1.92 to -0.21, P=.01) and body mass index (-0.45 kg/m2, 95% CI -0.78 to -0.12, P=.008). Moreover, a nonsignificant increase in physical activity was observed (0.17, 95% CI -2.21 to 2.55, P=.88).Conclusions: The findings of this study demonstrate the promising and emerging efficacy of using mobile phone app interventions for weight loss. Future studies are needed to explore the long-term efficacy of mobile app interventions in larger samples.
