NATIONAL HIV BEHAVIORAL SURVEILLANCE

描述（由申请人提供）：本提案概述了一项研究计划，以检查亚特兰大大都会统计区（MSA）艾滋病毒感染高危人群的风险行为，作为疾病控制和预防中心国家艾滋病毒行为监测（NHBS）系统的一部分。类似的研究正在全国其他参与城市进行。研究小组将从以下高风险群体进行数据收集的循环;除了拟议招募的男-女变性妇女（MTF）外，还包括男男性行为者（MSM），高风险异性恋者（HET）和静脉注射毒品使用者（IDU）。作为这项奋进的一部分，将在计划于2011年1月至2015年12月进行的最多五个数据收集和活动周期内招募总计1650名成年人。收集的数据将有助于研究人员了解这些高危人群中促进艾滋病毒风险的因素。该项目的每个周期将包括两个阶段：形成性研究阶段和行为监测数据收集阶段。数据收集将使用旨在收集人口统计信息、性/吸毒风险信息以及艾滋病毒检测信息的标准化问卷。数据收集阶段的抽样方法将是特定数据收集周期所特有的。IDU、HET和MTF周期将使用响应者驱动采样（RDS），而MSM周期将使用基于场地的时空采样（VBS）。鉴于最近疾病预防控制中心对亚特兰大MSA的排名为2008年新诊断的艾滋病毒感染的国家MSA/部门中的第二位，行为风险信息是减少该地区新感染的关键资产。该项目的主要目标是评估和监测艾滋病毒风险趋势、检测行为以及这些高危人群获得预防服务的情况。在收集数据后，NHBS的研究人员将与当地组织和机构合作，为利益相关者提供与这些高危人群中减少MSA艾滋病毒感染的预防目标相关的调查结果。

DESCRIPTION (provided by applicant): This proposal outlines a research plan to examine the risk behaviors of at-risk groups for HIV infection in the Atlanta Metropolitan Statistical Area (MSA) as a part of the Centers for Disease Control and Prevention's National HIV Behavioral Surveillance (NHBS) System. Similar research is being conducted in other participating cities across the country. The research team will conduct rotating cycles of data collection from the following high-risk groups; men who have sex with men (MSM), high-risk heterosexuals (HET) and intravenous drug-users (IDU) in addition to the proposed recruitment of male-to-female transgendered women (MTF). As part of this endeavor, a total of 1650 adults will be recruited over a maximum of five cycles of data collection and activities that are planned to take place from January 2011 through December 2015. The data collected will assist researchers in understanding the factors that facilitate the risk of HIV among each of these at-risk populations. Each cycle of this project will include two stages: the formative research stage and the behavioral surveillance data collection phase. Data collection will occur using a standardized questionnaire aimed at gathering demographic information, sexual/drug-using risk information as well has HIV testing information. Sample methodologies during the data collection phase will be unique to the particular data collection cycle. The IDU, HET, and MTF cycles will utilize respondent driven sampling (RDS), while the MSM cycle will utilize venue-based time-space sampling (VBS). Given the recent CDC ranking for the Atlanta MSA as 2nd among the national MSA/Divisions for 2008 newly diagnosed HIV infection, behavioral risk information is a critical asset to reducing new infections in the area. The main objective of this project is to assess and monitor trends in HIV risk, testing behaviors and access to preventive services among these populations at highest risk for infection. Following data collection, NHBS researchers will collaborate with local organizations and agencies to provide stakeholders with findings relevant to meeting prevention goals of reducing HIV infection in the MSA among these high-risk populations.
