National HIV Behavioral Surveillance, Los Angeles County

项目概要/摘要 监测艾滋病毒危险行为、艾滋病毒感染和艾滋病毒预防方案的使用情况， 在艾滋病毒风险增加的人群中，洛杉矶县公共卫生部（LACDPH）的艾滋病毒 流行病学方案建议在2011-2015年期间实施艾滋病毒行为监测系统。的 该系统将包括在男男性行为者、注射毒品者、 吸毒者（IDU）和有艾滋病毒感染风险的异性恋者（HET），使用基于场所的和应答者- 驱动抽样方法。收集的行为数据将用于为当地艾滋病毒预防规划提供信息， 并为国家艾滋病毒行为监测数据库做出贡献。这个项目的总体目标是 一项建议是维持我们的NHBS系统，以监测高危人群中艾滋病毒风险行为的长期趋势 洛杉矶县的人口。此外，我们还提出了三项补充研究活动， 将使我们能够a）在我们的第三个MSM周期中帮助开发新的艾滋病毒检测技术; B）估计 MSM、IDU和HET人群中B和C型肝炎的患病率;以及c）进行一个周期的NHBS， 至少200名所有种族/民族的男女变性人（TG）。为了实现这些目标， 我们确定了以下具体目标： 1.进行年度行为调查。我们将监测艾滋病毒危险行为的流行情况， 通过在男男性行为者、注射吸毒者、 2010年国家保健和预算调查六个周期中有感染艾滋病毒风险的异性恋者和男变女变性者， 洛杉矶县。 2.提供HIV和B和C型肝炎检测。我们会为以下人士提供快速及标准的爱滋病病毒测试服务， NHBS的参与者，并使用这些结果数据来估计艾滋病毒的流行率和发病率。我们还将 提供筛查测试，以检测五个NHBS周期中B和C型肝炎感染的证据，并提供 在NHBS-MSM 3期间参与开发新的艾滋病毒检测技术。 3.与当地合作伙伴合作。我们会让本地研究人员参与质性研究活动， 我们将与当地社区机构合作，共同开发当地使用的调查问题， 战略布局 4.评估NHBS系统。我们将与CDC合作，监测当地的质量，效率， NHBS数据收集和实施方法的价值。

Project Summary/Abstract To monitor the prevalence of HIV risk behaviors, HIV infection, and the use of HIV prevention programs among populations at increased risk for HIV, the Los Angeles County Department of Public Health's (LACDPH) HIV Epidemiology Program proposes to implement an HIV behavioral surveillance system during 2011-2015. The system will involve alternating cross-sectional surveys among men who have sex with men (MSM), injecting drug users (IDU), and heterosexuals at risk for HIV infection (HET) using both venue-based and respondent- driven sampling methods. The collected behavioral data will be used to inform local HIV prevention planning as well as to contribute to a national HIV behavioral surveillance (NHBS) database. The overall goal of this proposal is to maintain our NHBS system for monitoring long-term trends in HIV risk behaviors among high-risk populations in Los Angeles County. In addition, we are proposing three supplemental research activities that will allow us to a) help develop new HIV-testing technologies during our third MSM cycle; b) estimate the prevalence of hepatitis B and C in MSM, IDU, and HET populations; and c) conduct one cycle of NHBS with a minimum of 200 male-to-female transgender persons (TG) of all races/ethnicities. To accomplish these goals, we have identified the following specific aims: 1. Conduct annual behavioral surveys. We will monitor the prevalence of HIV risk behaviors and access to and use of HIV prevention programs by administering standardized questionnaires among MSM, IDU, heterosexual, and male-to-female transgender persons at risk of HIV infection across six NHBS cycles in Los Angeles County. 2. Offer HIV and hepatitis B and C testing. We will provide rapid and standard HIV testing services to NHBS participants and use these outcome data to estimate HIV prevalence and incidence. We will also offer screening tests to detect evidence of hepatitis B and C infection across five NHBS cycles and offer participation in developing new HIV testing technologies during NHBS-MSM3. 3. Collaborate with local partners. We will engage local researchers in qualitative research activities and we will work with local community agencies to co-develop local-use survey questions and implementation strategies. 4. Evaluate the NHBS system. We will work collaboratively with CDC to monitor the local quality, efficiency, and value of NHBS data collection and implementation methods.
