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面谈、重点小组和人种学评估进行形成性研究，以拟定当地调查问题，并确定当地开展实地研究活动的场所。德克萨斯国立卫生研究院项目团队将在达拉斯-沃斯堡-阿灵顿大都会统计区的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)的艾滋病毒危险行为、艾滋病毒预防服务的获得和利用进行匿名横断面调查。每个MSM和IDU周期的合格参与者将完成至少500份调查，HET周期的合格参与者将在2011年1月至2015年12月期间使用基于场地的时空抽样和受访者驱动的抽样方法，适当地为目标人群完成450份调查。还将对自愿和匿名的参与者进行艾滋病毒检测，以评估每个高危群体的艾滋病毒血清阳性率。此外，自愿和匿名的乙肝、丙型肝炎和梅毒检测将在参与者同意的情况下进行，以评估乙肝、丙型肝炎和梅毒的血清阳性率。所有调查、艾滋病毒检测以及乙肝病毒、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，并将研究结果传播到地方和国家监测报告系统、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。此外，关键风险行为指标的潜在研究主题将由德克萨斯国家健康保险研究联盟探索，并通过摘要、演示文稿和手稿进行传播。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 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.
