DESCRIPTION (provided by applicant): This research program grant application (R01) requests funds to conduct basic investigation of how social networks affect risk and risk reduction practices longitudinally in the context of sex-drug use within a community-based sample of younger Black men (16-29) who have sex with men (YBMSM) in order to identify critical points for intervention to reduce HIV transmission. YBMSM are embedded within heterogeneous Black communities. From the perspective of an individual YBMSM, his social network often include close confidants such as primary partners, relatives and friends who may exert supportive or antagonistic influences on his behavior and choice of partner(s). Many of these friends may crossover between the non-sexual and sexual components of one's network over time. Additionally, numerous other structures and institutions such as the ballroom community, detention centers/jails and internet social networking sites shape YBMSM networks and norms. How YBMSM are positioned within these rich and dynamic social environments and the considerable influence their social networks have on sex partner selection, sexual/drug related practices and risk-reduction behavior with specific partners has only recently begun to be explored. Our analytic approach focuses on components of the Auerbach 'social drivers' model applied to YBMSM, with particular attention to two components that this team is well positioned to study: norms and networks. These factors shape individuals' behaviors and practices modulated by situational factors such as sex-drug use. Based upon our preliminary work, we found that 1) dyadic mixing by risk behaviors (UAI, sex-drug use, group sex); 2) influences from social network members; and 3) composition of non-sexual social networks are associated with risk and biomedical prevention interventions in cross-sectional analyses of YBMSM. Thus far however, causal associations between networks and other 'social drivers' of HIV infection among BMSM, have been elusive. Accordingly, utilizing a 3 wave longitudinal cohort approach we aim to: 1) Describe the dynamics of social networks among YBMSM ages 16-29, and estimate the relationships between specific network attributes (e.g., confidant composition and component size) and subsequent risk/risk reduction behaviors, including their interaction with various social structures and institutions; 2) Examine the relationships between social networks, norms, risk/risk reduction practices and HIV/STI infection over time among this sample and their extended networks; 3) Determine the extent to which situational factors such as sex-drug use mediates the relationship between social network characteristics, norms and risk/risk reduction practices over time; and 4) Explore how learning that one is HIV positive affects social networks, norms and risk/risk reduction practices. This research is a necessary step in the development of scientifically-based network interventions that can complement combination interventions targeted to diverse YBMSM groups and their extended networks.

描述（由申请人提供）：本研究计划拨款申请 (R01) 要求提供资金，以在以社区为基础的男男性接触者 (YBMSM) 年轻黑人男性 (16-29) 样本 (YBMSM) 中，在性药物使用的背景下，对社交网络如何纵向影响风险和风险降低实践进行基本调查，以确定减少艾滋病毒传播的干预关键点。 YBMSM 嵌入到异质黑人社区中。从个体YBMSM的角度来看，他的社交网络通常包括亲密的知己，例如主要伴侣、亲戚和朋友，他们可能对他的行为和伴侣的选择产生支持或敌对的影响。随着时间的推移，这些朋友中的许多人可能会在网络中的非性和性成分之间交叉。此外，许多其他结构和机构，例如舞厅社区、拘留中心/监狱和互联网社交网站，塑造了 YBMSM 网络和规范。 YBMSM 如何在这些丰富且充满活力的社会环境中定位，以及他们的社交网络对性伴侣选择、性/毒品相关做法以及特定伴侣的风险降低行为的巨大影响，直到最近才开始被探索。 我们的分析方法侧重于应用于 YBMSM 的奥尔巴赫“社会驱动因素”模型的组成部分，特别关注该团队非常适合研究的两个组成部分：规范和网络。 这些因素塑造了个人的行为和做法，并受到性药物使用等情境因素的调节。根据我们的初步工作，我们发现：1）危险行为（UAI、性药物使用、群体性行为）的二元混合； 2）来自社交网络成员的影响； 3) 在 YBMSM 横断面分析中，非性社交网络的组成与风险和生物医学预防干预措施相关。然而迄今为止，网络与 BMSM 中 HIV 感染的其他“社会驱动因素”之间的因果关系尚不清楚。因此，利用三波纵向队列方法，我们的目标是：1）描述16-29岁YBMSM中社交网络的动态，并估计特定网络属性（例如，知己组成和组件大小）与随后的风险/风险降低行为之间的关系，包括它们与各种社会结构和机构的互动； 2) 检查该样本及其扩展网络中社交网络、规范、风险/风险降低做法与 HIV/STI 感染之间随时间的关系； 3) 确定随着时间的推移，性药物使用等情境因素在多大程度上调节社交网络特征、规范和风险/风险降低实践之间的关系； 4) 探索得知自己感染艾滋病毒后如何影响社交网络、规范和风险/降低风险的做法。这项研究是开发基于科学的网络干预措施的必要步骤，可以补充针对不同 YBMSM 群体及其扩展网络的组合干预措施。
