DESCRIPTION (provided by applicant): HIV risk-reduction interventions traditionally have emphasized individual-centered behavioral prevention approaches. Despite their success, the HIV/AIDS epidemic has not come to a halt, especially not among African Americans, a group that is disproportionately impacted. Structural interventions, which tend to be multilevel, are less common even though structural factors often create vulnerable populations and sustain an environment that is supportive of continued engagement in HIV risk behaviors. In the proposed study, we will investigate how individuals interact with and impact their neighborhood environments. Specifically, we focus on the link between the individual and neighborhood context and the role of structural and environmental factors. We propose a multilevel, longitudinal design and the specific aims are: (1) to investigate the relationships between neighborhood context, neighborhood perceptions, and individual characteristics, and HIV sexual risk-taking and the link between this risk-taking and HIV status; (2) to examine the association between neighborhood context, neighborhood perceptions, individual characteristics, and injection drug use related HIV risk-taking and this risk-taking and HIV status; and (3) to identify the spatial patterns of HIV risk-taking and to investigate neighborhood and individual-level characteristics associated with these spatial patterns. The guiding conceptual model builds on social disorganization theory. Recruitment uses targeted sampling strategies across 50 census block groups, with varied characteristics, and which serve as a proxy for neighborhoods. Our pilot data show these to vary according to key characteristics. In addition, we will explore the local context in which the respondents move. The study sample will consist of 1,500 African American women and men. Comparisons will be drawn based on drug use status, gender, and among the men, sexual orientation. The project comprises distinct data sources, namely: individual interviews, individual HIV status, systematic observations, data from the 2000 U.S. Census, and part 1 crime, drug arrests, and alcohol outlet data. Interviews will be conducted at three time points: baseline and 6 and 12 month follow-up. Systematic observations and a review of crime, drug arrests and alcohol outlet data will occur at baseline and at 12 month follow-up. The analytical approach combines longitudinal multilevel analyses and spatial mapping. The study has theoretical and research significance as its findings may provide useful information for structural interventions, targeting neighborhood structural and environmental factors, that support existing and new HIV prevention approaches. By incorporating partners such as policy-makers, urban planners, economists, legal experts and the wider research community, the public health response to HIV will be enhanced. PUBLIC HEALTH RELEVANCE: The proposed study focuses on the dynamic and complex relationship between individual and neighborhood context. Specifically, the focus is on HIV risk-taking and HIV status among adult African American men and women, including men-who-have-sex-with-men and drug users. The multilevel, longitudinal study will provide information necessary to inform the development, implementation and evaluation of multifaceted HIV risk-reduction interventions, with an emphasis on addressing structural and environmental risk factors.

描述（由申请人提供）：艾滋病毒风险降低干预措施传统上强调以个人为中心的行为预防方法。尽管他们取得了成功，但艾滋病毒/艾滋病的流行并没有停止，特别是在非洲裔美国人中间，这个群体受到的影响不成比例。结构性干预措施往往是多层次的，不太常见，尽管结构性因素往往会造成弱势群体，并维持一种有利于继续从事艾滋病毒风险行为的环境。在拟议的研究中，我们将调查个人如何与他们的邻里环境互动和影响。具体来说，我们专注于个人和邻里环境之间的联系和结构和环境因素的作用。本研究采用多水平纵向研究设计，具体目的是：（1）探讨社区环境、社区认知、个体特征与HIV性风险行为的关系，以及HIV性风险行为与HIV感染状况之间的联系;（2）考察邻里背景、邻里感知、个人特征之间的关联，和注射毒品使用相关的艾滋病毒风险承担和这种风险承担和艾滋病毒状态;（3）确定艾滋病毒风险承担的空间模式，并调查与这些空间模式相关的社区和个人水平的特征。指导性概念模型建立在社会解体理论之上。招募使用有针对性的抽样策略，在50个人口普查区块组，具有不同的特点，并作为一个代理的社区。我们的试点数据显示，这些根据关键特征而有所不同。此外，我们将探讨受访者移动的当地环境。研究样本将包括1，500名非洲裔美国女性和男性。将根据吸毒状况、性别和男性的性取向进行比较。该项目包括不同的数据来源，即：个人访谈，个人艾滋病毒状况，系统观察，2000年美国人口普查的数据，以及第1部分犯罪，毒品逮捕和酒精出口数据。将在三个时间点进行访谈：基线和6个月和12个月随访。将在基线和12个月随访时对犯罪、毒品逮捕和酒精出口数据进行系统观察和审查。分析方法结合纵向多层次分析和空间映射。该研究具有理论和研究意义，因为其研究结果可能为针对社区结构和环境因素的结构性干预提供有用的信息，支持现有和新的艾滋病预防方法。通过吸收决策者、城市规划者、经济学家、法律的专家和更广泛的研究界等伙伴参与，将加强对艾滋病毒的公共卫生反应。 公共卫生相关性：拟议的研究重点是个人和邻里环境之间的动态和复杂的关系。具体而言，重点是非洲裔美国成年男子和妇女，包括男男性行为者和吸毒者中的艾滋病毒风险和艾滋病毒状况。这一多层次的纵向研究将提供必要的信息，为制定、实施和评价多方面的减少艾滋病毒风险干预措施提供信息，重点是解决结构和环境风险因素。
