OBJECTIVE
Our aim was to evaluate the use and effectiveness of interventions using social networking sites (SNSs) to change health behaviors.
MATERIALS AND METHODS
Five databases were scanned using a predefined search strategy. Studies were included if they focused on patients/consumers, involved an SNS intervention, had an outcome related to health behavior change, and were prospective. Studies were screened by independent investigators, and assessed using Cochrane's 'risk of bias' tool. Randomized controlled trials were pooled in a meta-analysis.
RESULTS
The database search retrieved 4656 citations; 12 studies (7411 participants) met the inclusion criteria. Facebook was the most utilized SNS, followed by health-specific SNSs, and Twitter. Eight randomized controlled trials were combined in a meta-analysis. A positive effect of SNS interventions on health behavior outcomes was found (Hedges' g 0.24; 95% CI 0.04 to 0.43). There was considerable heterogeneity (I(2) = 84.0%; T(2) = 0.058) and no evidence of publication bias.
DISCUSSION
To the best of our knowledge, this is the first meta-analysis evaluating the effectiveness of SNS interventions in changing health-related behaviors. Most studies evaluated multi-component interventions, posing problems in isolating the specific effect of the SNS. Health behavior change theories were seldom mentioned in the included articles, but two particularly innovative studies used 'network alteration', showing a positive effect. Overall, SNS interventions appeared to be effective in promoting changes in health-related behaviors, and further research regarding the application of these promising tools is warranted.
CONCLUSIONS
Our study showed a positive effect of SNS interventions on health behavior-related outcomes, but there was considerable heterogeneity. Protocol registration The protocol for this systematic review is registered at http://www.crd.york.ac.uk/PROSPERO with the number CRD42013004140.
目的
我们的目的是评估使用社交网站（SNS）改变健康行为的干预措施的使用情况及效果。
材料与方法
采用预定义的检索策略对五个数据库进行检索。纳入的研究需聚焦于患者/消费者，涉及SNS干预，有与健康行为改变相关的结果，且为前瞻性研究。研究由独立研究者进行筛选，并使用Cochrane的“偏倚风险”工具进行评估。随机对照试验纳入荟萃分析。
结果
数据库检索共获得4656条引文；12项研究（7411名参与者）符合纳入标准。Facebook是使用最多的SNS，其次是特定健康领域的SNS，然后是Twitter。八项随机对照试验纳入荟萃分析。发现SNS干预对健康行为结果有积极影响（Hedges' g 0.24；95%置信区间0.04至0.43）。存在相当大的异质性（I² = 84.0%；T² = 0.058），且无发表偏倚的证据。
讨论
据我们所知，这是第一项评估SNS干预改变健康相关行为有效性的荟萃分析。大多数研究评估的是多成分干预措施，这在分离SNS的特定效果方面存在问题。纳入的文章很少提及健康行为改变理论，但有两项特别创新的研究使用了“网络改变”，显示出积极效果。总体而言，SNS干预似乎在促进健康相关行为改变方面有效，有必要对这些有前景的工具的应用进行进一步研究。
结论
我们的研究表明SNS干预对健康行为相关结果有积极影响，但存在相当大的异质性。方案注册 本系统评价的方案已在http://www.crd.york.ac.uk/PROSPERO注册，注册号为CRD42013004140。
