Neighborhoods, Mobility and HIV Among Young MSM

 描述(由申请人提供)：该项目寻求通过使用创新的方法方法，包括实时地理空间方法和地理定位的推特帖子，调查跨社区的空间流动性以及全球定位系统(GPS)定义的活动空间社区与纽约市大都会地区男男性行为(MSM)年轻男性中艾滋病毒风险之间的关系。我们将随机招募250名年轻MSM参加NIH资助的P18队列研究，在拟议的研究中，以解决研究的目标。资格要求包括报告在过去6个月内与另一名男性发生过性关系；艾滋病毒血清阴性；自我报告没有限制日常体力活动；愿意完成为期两周的全球定位系统方案。参与者将按照我们在之前的可行性研究项目中使用的协议佩戴GPS设备。拟议研究的结果将影响艾滋病毒预防干预活动。首先，这是 研究将为社区层面的具体政策干预提供信息。例如，通过在犯罪率高的地区增加对当地警察的关注，加强社区努力打击女同性恋者、男同性恋者、双性恋者和变性人(LGBT)仇恨犯罪的社区比率，可能是一种艾滋病毒预防干预措施。其次，鉴于我们将了解年轻MSM的旅行模式，我们可以确定艾滋病毒检测/预防干预的地理位置，这是对文献的进步，因为此类干预通常在空间上不是有针对性的。最后，这一点 研究还将有助于确定地理位置，以便在研究中招募年轻的MSM 研究(一种改进的基于场地的抽样方法)，在这一未被研究的群体中。

 DESCRIPTION (provided by applicant): This project seeks to investigate spatial mobility across neighborhoods as well as relationships between Global Positioning System (GPS)-defined activity space neighborhoods and HIV risk among young men who have sex with men (MSM) in the New York City metropolitan area, through the use of innovative methodological approaches including real-time geospatial methods and geo-located Twitter posts. We will randomly enroll 250 young MSM in the NIH-funded P18 Cohort Study in the proposed study to address the aims of the research. Eligibility requirements include report having had sex with another male in the past 6 months; HIV- seronegative; self-report no restrictions to usual physical activity; and willingness to complete a two-week GPS protocol. Participants will wear the GPS device following protocols we have used in our previous feasibility research projects. Findings from the proposed research will impact HIV prevention intervention activities. First, this research will inform specific neighborhood-level policy interventions. For example, increasing community efforts to combat lesbian, gay, bisexual and transgender (LGBT) hate crime neighborhood rates through increased local police attention in high-crime locations may be an HIV prevention intervention. Second, given that we will know the travel patterns of young MSM, we can identify geographic locations for HIV testing/prevention interventions, which is an advancement of the literature as such interventions are not often spatially targeted. Finally, this research will also facilitate identifying geographic locations for recruiting young MSM in research studies (an improved method of venue-based sampling), in this understudied group.
