越来越多的研究表明，肥胖可以被理解为一种复杂的生物行为状况，受到社会关系和社会网络的影响。社交网络分析使我们能够研究个人的网络特征(例如，受欢迎程度)如何与肥胖和肥胖相关行为相关联。这项研究的目的是(A)检查非裔美国人教会的网络成员在身体质量指数(BMI)和肥胖相关行为(体力活动、饮食、饮酒)方面是否相似，以及(B)检查个人的网络特征，如受欢迎程度(即接受同龄人的提名)和扩张性(即向同龄人发送提名)是否与BMI和肥胖相关行为有关。我们使用横断面研究设计，并使用指数随机图模型对三个基于非裔美国人教会的社会网络(网络A、B和C，n=281)进行了社会网络分析。在基于教会的三个网络中，网络成员在BMI上没有显著的相似性。每三个网络中就有一个在水果和蔬菜消费(网络B)、快餐消费(网络C)、体育活动、久坐行为和饮酒(网络A)方面表现出相似之处。体重指数高的非裔美国人更受欢迎，脂肪摄入量和饮酒量更大的人也更受欢迎。我们的发现支持这样一种观点，即我们需要通过瞄准有影响力的个人和现有的关系来改善与肥胖相关的行为，并利用社交网络开发肥胖干预措施。我们的发现在不同教会之间的差异程度也表明，应该在独特的社会背景下理解个人肥胖相关行为和网络特征之间的关系。
A growing body of research suggests that obesity can be understood as a complex and biobehavioral condition influenced by social relationships ─social networks. Social network analysis allows us to examine how an individual’s network characteristics (e.g., popularity) are associated with obesity and obesity-related behaviors. The objectives of the study were to (a) examine whether network members in African American churches are similar in body mass index (BMI) and obesity-related behaviors (physical activity, eating, alcohol consumption) and (b) examine whether an individual’s network characteristics, such as popularity (i.e., receiving nominations from peers) and expansiveness (i.e., sending nominations to peers) are associated with BMI and obesity-related behaviors. We used a cross-sectional study design and conducted social network analysis using Exponential random graph models with three African American church-based social networks (network A, B, and C, n = 281). There were no significant network members’ similarities on BMI in the three church-based networks. One out of three networks showed similarities in fruit and vegetable consumption (network B), fast food consumption (network C), physical activity, sedentary behaviors, and alcohol consumption (network A). African Americans with a high BMI were more popular, as were individuals with greater fat intake and alcohol consumption. Our findings support the perspective that we need to improve obesity-related behaviors by targeting influential individuals and existing ties and to develop obesity interventions using social networks. The degree to which our findings varied across churches also suggests that the relationship among an individual’s obesity-related behaviors and network characteristics should be understood in the unique social context.
