目标。我们的目的是测试共享体型标准在体型和肥胖的社会传染中的假设作用。方法。使用 2009 年从亚利桑那州凤凰城 101 名女性及其 812 名社会关系中收集的数据，我们评估了社会规范对以 3 种不同方式测量的共同体重指数 (BMI) 的间接影响。结果。我们证实了 Christakis 和 Fowler 的基本发现，即 BMI 和肥胖确实在社会上聚集，但我们发现体型标准只占这种影响的一小部分（最多 20%），并且仅通过 3 种途径中的 1 种实现。结论。如果共同的社会规范在肥胖的社会传染中只发挥很小的作用，那么旨在改变对适当体重指数或体型的观念的干预措施可能不如那些更直接地改变行为的干预措施有用，例如通过改变饮食习惯或改变饮食摄入的机会和限制。 （美国公共卫生杂志。2011；101：S295-S300。doi：10.2105/AJPH.2010.300053）
Objectives. We aimed to test the hypothesized role of shared body size norms in the social contagion of body size and obesity.Methods. Using data collected in 2009 from 101 women and 812 of their social ties in Phoenix, Arizona, we assessed the indirect effect of social norms on shared body mass index (BMI) measured in 3 different ways.Results. We confirmed Christakis and Fowler's basic finding that BMI and obesity do indeed cluster socially, but we found that body size norms accounted for only a small portion of this effect (at most 20%) and only via 1 of the 3 pathways.Conclusions. If shared social norms play only a minor role in the social contagion of obesity, interventions targeted at changing ideas about appropriate BMIs or body sizes may be less useful than those working more directly with behaviors, for example, by changing eating habits or transforming opportunities for and constraints on dietary intake.
