来自不同领域的研究人员和政策制定者正在努力了解肥胖的生物和社会原因，以便制定政策，干预措施和建议，以阻止或扭转肥胖的增加。一个潜在的有希望的方法是利用社会联系的影响力。这种方法的一个重要基础是批判性地分析现有数据，这些数据涉及体重是否以及如何受到密切的社会接触，特别是朋友的影响。这篇系统性综述检查了来自已发表的研究的证据，这些研究涉及朋友对体重的影响。16项研究中的大多数得出结论，有影响的证据：6个报告说，朋友影响体重和10个报告的影响在某些情况下或规格的证据。然而，这些文献揭示的影响机制很少。有有限的证据表明，朋友关于体重的沟通与体重状况有关，也没有令人信服的证据表明朋友的行为会影响一个人的体重。许多旨在考察影响力的研究并没有探索影响力的机制。未来研究的重点是了解朋友如何、何时以及在多大程度上影响肥胖风险。
Researchers and policymakers from diverse fields are engaged in efforts to understand the biological and social causes of obesity in order to develop policies, interventions, and recommendations to stop or reverse increases in obesity. One potentially promising approach is to harness influence from social contacts. An important foundation for this approach involves critically analyzing available data regarding whether and how body weight can be affected by close social contacts, especially friends. This systematic review examines evidence from published studies addressing the influences of friends on body weight. The majority of the sixteen studies conclude that there is evidence of influence: six reported that friends influence body weight and ten reported evidence of influence in some circumstances or specifications. However, this literature sheds little light on mechanisms of influence. There is limited evidence that friends’ communication about weight is associated with weight status and no compelling evidence that friends’ behaviors affect one’s weight. Many of the studies best designed to examine influence were the ones that did not explore mechanisms of influence. A priority for future research is to understand how, when, and how much friends affect the risk of obesity.
