HIV BEHAVIORAL SURVEILLANCE

描述（由申请人提供）：疾病控制和预防中心（CDC）目前在美国25个大都市统计区（MSA）进行国家艾滋病毒行为监测（NHBS），包括西雅图海事局。我们建议从2008年到2010年继续在西雅图MSA实施NHBS。NHBS在西雅图MSA的目标是帮助指导和评估当地的艾滋病毒预防工作，保持一个持续的监测系统，以监测性行为和吸毒行为，艾滋病毒预防服务的获取和利用，以及艾滋病毒在男男性行为者（MSM），注射毒品使用者（IDU）和高危异性恋者（HET）中的流行和发病率。为了实现这一目标，我们建议与疾病预防控制中心和其他受资助的网站合作实施， 根据CDC NHBS方案，评估NHBS在三个目标人群中的持续性。具体来说，我们将在每个周期进行形成性评估，以指导调查的实施与定性方法研究员从华盛顿大学的合作。我们还将与西雅图地区的社区组织合作开展调查和实施工作，这些组织由CDC直接资助，或通过社区规划程序由州或地方资助，以分配联邦艾滋病毒预防资金。我们将每年进行一次调查，以评估艾滋病毒的危险行为，艾滋病毒预防服务的获得和利用，以及艾滋病毒感染的西雅图地区男男性接触者，注射吸毒者和HET。我们将每年轮换调查人群，2008年调查MSM，2009年调查IDU，2010年调查HET。我们将采用基于场地的时空抽样（VBS）和受访者驱动的抽样（RDS），每年完成500名合格参与者的调查。我们将在所有三个周期中为所有NHBS参与者提供自愿艾滋病毒咨询和检测，以评估艾滋病毒血清阳性率和发病率（使用最近艾滋病毒血清转换的血清学检测算法，STARHS）。我们将对NHBS系统进行评估，包括 抽样战略和数据收集方法，以确保该系统达到其目标，并提供建议，以提高质量，效率和实用性的NHBS在地方和国家。我们将分析来自所有三个NHBS调查周期的数据，并将调查结果传播给当地的艾滋病毒预防规划小组，公共卫生和社区艾滋病毒预防计划，以及参与艾滋病毒预防规划，评估和资源优先排序的其他受众。

DESCRIPTION (provided by applicant): The Centers for Disease Control and Prevention (CDC) currently conducts National HIV Behavioral Surveillance (NHBS) in 25 metropolitan statistical areas (MSA) in the U.S., including the Seattle MSA. We propose to continue NHBS in the Seattle MSA from 2008 to 2010. The goal of NHBS in the Seattle MSA is to help direct and evaluate local HIV prevention efforts by maintaining an ongoing surveillance system to monitor sexual and drug-use behaviors, HIV prevention service access and utilization, and the prevalence and incidence of HIV among men who have sex with men (MSM), injection drug users (IDU), and high-risk heterosexuals (HET). To accomplish this goal, we propose to collaborate with CDC and other funded sites in implementation and evaluation of the continuation of NHBS in the three target populations according to CDC NHBS protocols. Specifically, we will conduct a formative assessment in each cycle to guide survey implementation in collaboration with a qualitative methods researcher from the University of Washington. We will also collaborate on survey development and implementation with Seattle area community-based organizations that are directly funded by CDC or funded by state or local funding through the community planning process for allocating federal HIV prevention funds. We will conduct a survey each year to assess HIV risk behaviors, HIV prevention services access and utilization, and HIV infection among Seattle-area MSM, IDU and HET. We will rotate the survey population each year and survey MSM in 2008, IDU in 2009, and HET in 2010. We will employ venue-based time-space sampling (VBS) and respondent-driven sampling (RDS) and complete surveys with 500 eligible participants each year. We will provide voluntary HIV counseling and testing to all NHBS participants in all three cycles to assess HIV seroprevalence and incidence (using the serological testing algorithm for recent HIV seroconversion, STARHS). We will conduct evaluations of the NHBS system including sampling strategies, and data collection methods to ensure that the system meets its goals, and provide recommendations for improving the quality, efficiency and usefulness of NHBS both locally and nationally. We will analyze data from all three NHBS surveys cycles and disseminate findings to the local HIV Prevention Planning Group, public health and community-based HIV prevention programs, and other audiences involved in HIV prevention planning, evaluation, and resource prioritization.
