 DESCRIPTION (provided by applicant): This project seeks to utilize real-time geospatial methods to investigate relationships between Global Positioning System (GPS)-defined activity space neighborhoods, drug use and HIV risk among Black men who have sex with men (MSM) in the Jackson, Mississippi metropolitan statistical area (MSA). We will recruit 150 Black MSM in the proposed study to address the aims of the research using multiple community-based methods implemented in our current and past portfolio of work in Mississippi. Eligibility requirements include: self-report as African American or Black race; report having had sex (any physical contact that could lead to orgasm) with another male in the past six months; aged 18-29 years; reside in the five-county Jackson, MS MSA; self-report no restrictions to usual physical activity; and willingness to complete a two-week GPS protocol. Consistent with previous research conducted in the Jackson, MS MSA, including the NIH-funded Jackson Heart Study, participants will be recruited from urban and rural areas of counties that make up the Jackson, MS MSA. Participants will wear the GPS device following protocols we have used in our previous feasibility research projects. Of the 150 participants, fifty participants will be randomized to undergo two rounds of 2-week GPS protocol: at baseline, and after a 3-month follow-up period. Obtaining GPS data over time will enable us to understand the extent of spatial overlap in people's spatial patterns over time, which may vary in part due to seasonal variation. Findings from the proposed research will impact drug use and 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 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 Black MSM, we will be able to identify optimal geographic locations for drug use and HIV testing/prevention interventions. This will advance the literature given that such interventions ar seldom geographically targeted. Third, examining changes in spatial mobility (i.e. activity spaces) over time (3-month follow-up) will be useful in knowing whether the risks of particular spaces change or remain constant because different neighborhoods will have different risk profiles. If these risk environments change, this suggests that prevention needs to be very dynamic and fluid and perhaps need rapid change-detection feedback loops. Finally, this research will also facilitate the identification of geographic locations suitable for recruiting Blck MSM in research studies (an improved method of venue- based sampling), in this understudied group.

 描述（由申请人提供）：该项目旨在利用实时地理空间方法来调查全球定位系统（GPS）定义的活动空间社区，吸毒和艾滋病毒风险之间的关系，在杰克逊，密西西比大都市统计区（MSA）的黑人男性同性恋（MSM）。我们将在拟议的研究中招募150名黑人男男性接触者，以解决我们在密西西比当前和过去的工作组合中实施的多种基于社区的方法的研究目标。资格要求包括：自我报告为非裔美国人或黑人;报告在过去六个月内与另一名男性发生性关系（任何可能导致性高潮的身体接触）;年龄18-29岁;居住在MS MSA的五个县杰克逊;自我报告对日常体力活动没有限制;并愿意完成为期两周的GPS协议。与之前在杰克逊，MS MSA中进行的研究一致，包括NIH资助的杰克逊心脏研究，参与者将从构成杰克逊，MS MSA的县的城市和农村地区招募。参与者将按照我们在以前的可行性研究项目中使用的协议佩戴GPS设备。在150名参与者中，50名参与者将被随机分配接受两轮为期2周的GPS方案：基线时和3个月随访期后。随着时间的推移获得GPS数据将使我们能够了解人们的空间模式随着时间的推移而发生空间重叠的程度，这可能部分由于季节变化而有所不同。拟议研究的结果将影响药物使用和艾滋病毒预防干预活动。首先，这项研究将为具体的邻里政策干预提供信息。例如，通过加强当地警察对高犯罪率地区的关注，加强社区努力打击男女同性恋、双性恋和变性者的仇恨犯罪率，这可能是一种艾滋病毒预防干预措施。其次，鉴于我们将知道黑人男男性行为者的旅行模式，我们将能够确定药物使用和艾滋病毒检测/预防干预的最佳地理位置。这将推进文献，因为这种干预很少有地理目标。第三，检查空间移动性（即活动空间）随时间的变化（3个月随访）将有助于了解特定空间的风险是否发生变化或保持不变，因为不同的社区将具有不同的风险概况。如果这些风险环境发生变化，这表明预防需要非常动态和灵活，也许需要快速的变化检测反馈循环。最后，这项研究也将有助于确定地理位置适合招募黑人男男性接触者在研究研究（一种改进的方法，基于场地的抽样），在这个研究不足的群体。
