社交媒体应用程序通过促进教育、参与和同伴支持，有望促进在线体重管理干预。然而，社交媒体对体重管理的确切影响尚不清楚。本研究的目的是系统地描述社交媒体在在线体重管理干预中的使用和影响。检索PubMed、PsycINFO、EMBASE、Web of Science和Scopus中截至2013年3月25日发表的英语研究。通过检索电子检索文章的参考书目确定了其他研究。选择了针对所有年龄段个体的在线体重管理干预措施的随机对照试验，其中包括社交媒体组件。使用2个系统量表评价研究，以评估偏倚风险和研究质量。在识别的517篇引文中，20项研究符合合格标准。所有研究参与者都是成年人。由于纳入的研究在研究设计和报告的结局方面差异很大，因此未尝试对干预措施进行荟萃分析。虽然留言板和聊天室是最常见的社交媒体组成部分，但大多数研究都没有报道它们对体重结果的影响。只有一项研究测量了社交媒体的孤立效应。它发现参与者的参与度更高，但与体重相关的结果没有差异。总的来说，65%的研究是高质量的; 15%的研究是低偏倚风险的。尽管社交媒体被广泛使用，但很少有研究量化社交媒体在在线体重管理干预中的影响;因此，其影响仍然未知。虽然社交媒体可能在留住和吸引参与者方面发挥作用，但需要进行旨在衡量其影响的研究，以了解社交媒体是否以及如何有意义地改善体重管理。
Social media applications are promising adjuncts to online weight management interventions through facilitating education, engagement, and peer support. However, the precise impact of social media on weight management is unclear. The objective of this study was to systematically describe the use and impact of social media in online weight management interventions. PubMed, PsycINFO, EMBASE, Web of Science, and Scopus were searched for English-language studies published through March 25, 2013. Additional studies were identified by searching bibliographies of electronically retrieved articles. Randomized controlled trials of online weight management interventions that included a social media component for individuals of all ages were selected. Studies were evaluated using 2 systematic scales to assess risk of bias and study quality. Of 517 citations identified, 20 studies met eligibility criteria. All study participants were adults. Because the included studies varied greatly in study design and reported outcomes, meta-analysis of interventions was not attempted. Although message boards and chat rooms were the most common social media component included, their effect on weight outcomes was not reported in most studies. Only one study measured the isolated effect of social media. It found greater engagement of participants, but no difference in weight-related outcomes. In all, 65% of studies were of high quality; 15% of studies were at low risk of bias. Despite the widespread use of social media, few studies have quantified the effect of social media in online weight management interventions; thus, its impact is still unknown. Although social media may play a role in retaining and engaging participants, studies that are designed to measure its effect are needed to understand whether and how social media may meaningfully improve weight management.
