DESCRIPTION (provided by applicant): 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.

描述（由申请人提供）：为了监测艾滋病毒风险行为的流行情况、艾滋病毒感染情况以及艾滋病毒预防计划在艾滋病毒风险增加人群中的使用情况，洛杉矶县公共卫生部（LACDPH）艾滋病毒流行病学项目提议在2011-2015年期间实施艾滋病毒行为监测系统。该系统将包括对男男性行为者（MSM）、注射毒品使用者（IDU）和有艾滋病毒感染风险的异性恋者（HET）进行交替的横断面调查，采用基于地点和应答者驱动的抽样方法。收集到的行为数据将用于为当地的艾滋病毒预防规划提供信息，并为国家艾滋病毒行为监测（NHBS）数据库提供信息。该提案的总体目标是维持我们的NHBS系统，以监测洛杉矶县高危人群中艾滋病毒风险行为的长期趋势。此外，我们正在提议三项补充研究活动，这将使我们能够a)在我们的第三个男男性接触者周期中帮助开发新的艾滋病毒检测技术；b)估计男男性行为者、注射吸毒者和HET人群中乙型和丙型肝炎的流行情况；c)对至少200名所有种族/民族的男变女变性人（TG）进行一个周期的NHBS。为实现这些目标，我们确定了以下具体目标：进行年度行为调查。我们将通过在洛杉矶县六个NHBS周期内对MSM、IDU、异性恋和男变女跨性别者进行标准化问卷调查，监测艾滋病毒风险行为的流行情况以及艾滋病毒预防项目的可及性和使用情况。提供艾滋病毒、乙型和丙型肝炎检测。我们将为国民健康计划参与者提供快速和标准的艾滋病毒检测服务，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，以在5个NHBS周期内检测乙型和丙型肝炎感染的证据，并在NHBS- msm3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。我们将让当地研究人员参与定性研究活动，并将与当地社区机构合作，共同制定当地用途调查问题和实施战略。4. 评估NHBS系统。我们将与美国疾病控制与预防中心合作，监测当地国家卫生健康统计局数据收集和实施方法的质量、效率和价值。
