Texas National HIV 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个成年高危人群（男男性行为者（MSM）、注射吸毒者（IDU）和艾滋病毒风险增加的异性恋者（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2011年1月至2015年12月期间，每个MSM和IDU周期将对符合条件的参与者进行至少500次调查，在HET周期将对符合条件的参与者进行450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。此外，自愿和匿名的乙型肝炎（HBV）、丙型肝炎（HCV）和梅毒检测将对同意的参与者进行，以估计HBV、HCV和梅毒的血清阳性率。所有调查、艾滋病毒检测以及乙型肝炎病毒、丙型肝炎病毒和梅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元（定制的休闲车）中进行。将对研究数据进行分析，并将研究结果分发给地方和国家监测报告系统、以社区为基础的组织和艾滋病毒社区规划小组，以指导预防资源分配，设计和评估预防干预措施。此外，关键风险行为指标的潜在研究课题将由德克萨斯NHBS研究联盟探索，并通过摘要、演讲和手稿传播。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 to 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 increased risk of HIV (HET) in the Dallas Division, Dallas-Fort Worth-Arlington Metropolitan Statistical Area. A minimum of 500 surveys will be completed from eligible participants for each MSM and IDU cycle and 450 surveys will be completed from eligible participants for the HET cycle from January 2011 to December 2015 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 of each high risk group. Additionally, voluntary and anonymous hepatitis B (HBV), hepatitis C (HCV), and syphilis testing will be conducted on consenting participants to estimate HBV, HCV, and syphilis seroprevalence. All surveys, HIV testing, along with HBV, HCV, and syphilis 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 local and national surveillance reporting systems, to community based organizations, and to HIV community planning groups in order to guide prevention resource allocation and to design and evaluate prevention interventions. Further, potential research topics of key risk behavior indicators will be explored by the Texas NHBS research consortium and disseminated through abstracts, presentations, and manuscripts. 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.
