BEHAVIORAL SURVEILLANCE

描述(由申请人提供)：德克萨斯州国家艾滋病毒行为监测(NHBS)项目的目标是通过高危人群的艾滋病毒危险行为数据来监测艾滋病毒的流行，以指导德克萨斯州的地方艾滋病毒预防计划，并为国家艾滋病毒行为监测系统的发展做出贡献。在实施调查之前，将利用关键的信息提供人访谈、重点小组和人种学评估进行形成性研究，以制定当地调查问题，并确定开展实地研究活动的当地场所。德克萨斯国立卫生研究院项目团队将对达拉斯-沃斯堡-阿灵顿大都会统计局达拉斯分部的三个成年高危人群--男男性行为者(MSM)、注射吸毒者(IDU)和高危异性恋者(HET)--的艾滋病毒危险行为、艾滋病毒预防服务的获得和利用情况进行匿名横断面调查。在三年项目的每个周期内，将使用场地抽样、时空抽样和受访者驱动抽样方法，酌情为目标人群完成每个高危群体中符合条件的参与者进行的至少500项调查。还将对自愿和匿名的参与者进行艾滋病毒检测，以估计每个高危群体的艾滋病毒血清阳性率和发病率。所有调查和艾滋病毒检测将由一组训练有素的工作人员在安全的移动检测单元(定制休闲车)中进行。将分析研究数据，并将研究结果传播给社区组织和艾滋病毒社区规划小组，以指导预防资源分配，并设计和评估预防干预措施。德克萨斯州国家HBS还将对当地的NHBS系统、其采样系统和数据收集方法的质量、效率和有用性进行评估，以确保该系统满足项目目标。

DESCRIPTION (provided by applicant): The goal of the Texas National HIV Behavioral Surveillance (NHBS) project is to monitor the HIV epidemic through HIV risk behavior data of high risk groups in order to guide local HIV prevention programs in Texas and contribute to the development of a National HIV Behavioral Surveillance system. Formative research will be conducted prior to implementation of the survey using key informant interviews, focus groups, and ethnographic assessments to develop local survey questions and identify local venues for conducting field research activities. The Texas NHBS project team will conduct an anonymous, cross-sectional survey of HIV risk behaviors, access to and utilization of HIV Prevention services in three adult high risk populations, men who have sex with men (MSM), injecting drug users (IDU) and heterosexuals at risk (HET) in the Dallas Division, Dallas-Fort Worth-Arlington Metropolitan Statistical Area. A minimum of 500 surveys will be completed from eligible participants in each high risk group during each cycle of the three year project using venue based, time-space sampling and respondent driven sampling methodologies as appropriate for the target population. Voluntary and anonymous HIV testing will also be conducted on consenting participants to estimate HIV seroprevalence and incidence of each high risk group. All surveys and HIV testing will be conducted by a team of trained staff in a secure mobile testing unit (customized recreational vehicle). Research data will be analyzed and study findings will be disseminated to community based organizations and HIV community planning groups to guide prevention resource allocation and to design and evaluate prevention interventions. The Texas NHBS will also conduct evaluations of the local NHBS system, the quality, efficiency, and usefulness of its sampling systems and data collection methods to ensure the system is meeting the project goals.
