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风险行为数据来监测艾滋病毒的流行情况，以指导德克萨斯州当地的艾滋病毒预防项目，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，将进行形成性研究，使用关键信息者访谈、焦点小组和人种学评估来制定当地调查问题，并确定开展实地研究活动的当地场所。德克萨斯州NHBS项目团队将在达拉斯-沃斯堡-阿灵顿大都会统计区达拉斯分部对三名成年高危人群（男男性行为者（MSM）、注射吸毒者（IDU）和高危异性恋者（HET））进行艾滋病毒风险行为、获得和利用艾滋病毒预防服务的匿名横断面调查。在为期三年的项目的每个周期内，将对每个高风险群体的合格参与者进行至少500次调查，采用适合目标人群的地点抽样、时空抽样和受访者驱动抽样方法。还将对同意的参与者进行自愿和匿名艾滋病毒检测，以估计每个高危群体的艾滋病毒血清感染率和发病率。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一个安全的移动检测单位（定制的休闲车）进行。将对研究数据进行分析，并将研究结果分发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。德州NHBS还将对当地NHBS系统、采样系统的质量、效率和有用性以及数据收集方法进行评估，以确保系统达到项目目标。

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.
