本研究探讨网络中心的跨场地网络之间的合作，竞争和赞助关系的场地，为年轻男子谁与男性发生性关系（MSM）年龄在16至29岁的关系，他们的地理集中在芝加哥，伊利诺伊州和休斯敦，得克萨斯州。我们的物理场馆数据包括芝加哥的116个场馆和休斯顿的102个场馆。我们研究了不同关系的网络中心性与这些场所之间的地理强度之间的关系，并考虑了社区层面的社会经济健康决定因素。结果表明，年轻的MSM服务的社会和服务场所发现在物理上接近彼此往往有很大的中心性indegree值的基础上，在两个城市的竞争，并基于合作，只有在芝加哥。然而，没有证据表明，在赞助网络中占据中心地位与地理集中有关。综合起来，这些结果表明，艾滋病毒预防干预措施应考虑竞争的组织力量。这一战略可以改善服务，但仍有可能出现服务重叠和冗余，损害服务不足的地区，而在这些地区，经证明的干预措施可以产生最大的影响。
This study examines network centrality of inter-venue networks formed by collaboration, competition, and sponsorship relationships among venues that serve young men who have sex with men (MSM) aged 16 to 29 years in relation to their geographical concentrations in Chicago, Illinois, and Houston, Texas. Our data on the physical venues comprised 116 venues in Chicago and 102 venues in Houston. We examined the relationship between the network centrality of different relations and the geographical intensity among these venues, and considered neighborhood-level socioeconomic determinants of health. The results indicate that young MSM-serving social and service venues found in close physical proximity to one another tended to have large centrality indegree values based on competition in both cities, and based on collaboration only in Chicago. No evidence, however, was found that occupying a central position in the sponsorship networks was related to geographic concentration. Combined, these results suggest that HIV prevention interventions should consider the organizing force for competition. Such a strategy could result in better services, yet there may still be potential for overlap and redundancy in services at the expense of under-served regions where proven interventions could have the greatest impact.
