The global epidemic of obesity continues to escalate. Obesity accounts for an increasing proportion of the international socioeconomic burden of noncommunicable disease. Online social networking services provide an effective medium through which information may be exchanged between obese and overweight patients and their health care providers, potentially contributing to superior weight-loss outcomes. We performed a systematic review and meta-analysis to assess the role of these services in modifying body mass index (BMI). Our analysis of twelve studies found that interventions using social networking services produced a modest but significant 0.64 percent reduction in BMI from baseline for the 941 people who participated in the studies' interventions. We recommend that social networking services that target obesity should be the subject of further clinical trials. Additionally, we recommend that policy makers adopt reforms that promote the use of anti-obesity social networking services, facilitate multistakeholder partnerships in such services, and create a supportive environment to confront obesity and its associated noncommunicable diseases.
肥胖症在全球范围内持续蔓延。肥胖症在非传染性疾病的国际社会经济负担中所占比例不断上升。在线社交网络服务提供了一种有效的媒介，肥胖和超重患者及其医疗保健提供者可以通过该媒介交流信息，从而有可能实现更好的减肥效果。我们进行了系统评价和荟萃分析，以评估这些服务在改变体重指数（BMI）方面的作用。我们对 12 项研究的分析发现，对于参与研究干预的 941 人来说，使用社交网络服务的干预措施使 BMI 从基线水平适度但显著降低了 0.64%。我们建议进一步开展临床试验，以研究针对肥胖症的社交网络服务。此外，我们建议政策制定者采取改革措施，鼓励使用抗肥胖症社交网络服务，促进此类服务中的多方利益相关者伙伴关系，并营造支持性环境，以应对肥胖症及其相关的非传染性疾病。
