NATIONAL HIV BEHAVIORAL SURVEILLANCE

描述(由申请人提供)：作为疾病控制和预防中心全国艾滋病毒行为监测(NHBS)系统的一部分，本提案概述了一项研究计划，该计划旨在检查亚特兰大大都会统计区(MSA)艾滋病毒感染高危群体的危险行为。类似的研究也在全国其他参与城市进行。研究小组将轮流收集以下高危人群的数据：男男性行为者(MSM)、高危异性恋者(HET)和静脉注射吸毒者(IDU)，以及拟议招募的男女变性人(MTF)。作为这一努力的一部分，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中招募1650名成年人。收集的数据将帮助研究人员了解促进这些高危人群感染艾滋病毒风险的因素。该项目的每个周期将包括两个阶段：形成研究阶段和行为监测数据收集阶段。将使用标准化问卷收集数据，目的是收集人口统计信息、性/药物使用风险信息以及艾滋病毒检测信息。数据收集阶段的样本方法对于特定的数据收集周期是独一无二的。IDU、HET和MTF周期将使用受访者驱动采样(RDS)，而MSM周期将使用基于场地的时空采样(VBS)。鉴于疾控中心最近对亚特兰大MSA的排名在2008年新诊断的艾滋病毒感染的全国MSA/分部中排名第二，行为风险信息对于减少该地区的新感染是一项关键资产。该项目的主要目标是评估和监测这些感染风险最高的人群在艾滋病毒风险、检测行为和获得预防服务方面的趋势。在数据收集之后，NHBS的研究人员将与当地组织和机构合作，向利益攸关方提供与实现预防目标相关的结果，即在这些高危人群中减少MSA的艾滋病毒感染。

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.
