本研究探讨青少年友谊网络中与肥胖相关的行为，因为青少年同伴已被确定为许多健康行为的重要决定因素。我们应用ERGM选择模型对单个网络进行观察，以确定亲密的青少年朋友是否有类似的行为，并探索行为与受欢迎程度之间的关联。在三分之二的以学校为基础的友谊网络中，同性朋友在有组织的体育活动方面被发现是相似的。女性朋友被发现参与类似的基于屏幕的行为，男性朋友在高热量食物的消费方面也倾向于相似。受欢迎程度（接收领带）也与一些行为有关，尽管这些影响是性别特异性的，并且在网络中存在差异。皇冠版权所有（C）2009年出版的爱思唯尔B.V.保留所有权利。
This study examines obesity-related behaviors within adolescent friendship networks, because adolescent peers have been identified as being important determinants of many health behaviors. We applied ERGM selection models for single network observations to determine if close adolescent friends engage in similar behaviors and to explore associations between behavior and popularity. Same-sex friends were found to be similar on measures of organized physical activity in two out of three school-based friendship networks. Female friends were found to engage in similar screen-based behaviors, and male friends tended to be similar in their consumption of high-calorie foods. Popularity (receiving ties) was also associated with some behaviors, although these effects were gender specific and differed across networks. Crown Copyright (C) 2009 Published by Elsevier B.V.
