Many unhealthy behaviors develop during adolescence, and these behaviors can have fundamental consequences for health and mortality in adulthood. Social network structure and the degree of homophily in a network affect how health behaviors and innovations are spread. However, the degree of health behavior homophily across different social ties and within subpopulations is unknown. This paper addresses this gap in the literature by using a novel regression model to document the degree of homophily across various relationship types and subpopulations for behaviors of interest that are related to health outcomes. These patterns in health behavior homophily have implications for which behaviors and ties should be the subjects of future research and for predicting how homophily may shape health programs focused on specific subpopulations (gender, race, class, health status) or a specific social context (families, peer groups, classrooms, or school activities).
许多不健康行为在青少年时期形成，这些行为会对成年后的健康和死亡率产生根本性影响。社交网络结构以及网络中的同质性程度会影响健康行为和创新的传播方式。然而，不同社会关系以及亚群体内部健康行为的同质性程度尚不清楚。本文通过使用一种新颖的回归模型来填补文献中的这一空白，以记录与健康结果相关的感兴趣行为在各种关系类型和亚群体中的同质性程度。健康行为同质性的这些模式对于哪些行为和关系应成为未来研究的主题，以及预测同质性如何塑造针对特定亚群体（性别、种族、阶级、健康状况）或特定社会背景（家庭、同龄人群体、教室或学校活动）的健康项目具有启示意义。
