NATIONAL HIV BEHAVIORAL SURVEILLANCE - LOS ANGELES

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方案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2008-2010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）、注射吸毒者（IDU）和有感染艾滋病毒风险的异性恋者（HET）进行交替的横断面调查。收集到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作出贡献。该提案的总体目标是获得支持，以维持现有的艾滋病毒行为监测系统，以监测洛杉矶县高危人群中艾滋病毒危险行为流行的长期趋势。为实现这一目标，确定了四个具体目标：进行年度行为调查。该系统将通过对洛杉矶县艾滋病毒感染风险较高的至少500名男男性行为者、500名注射吸毒者和500名异性恋者进行标准化的横断面调查，监测艾滋病毒风险行为的流行情况，以及艾滋病毒预防计划的获取和使用情况。将采用时空和受访者驱动的抽样方法来招募这些调查的参与者。2. 提供艾滋病毒咨询和检测。将向调查参与者提供快速和标准的艾滋病毒检测服务。将获得每个危险人群的艾滋病毒流行率和发病率估计数。3. 与当地合作伙伴合作。艾滋病毒流行病学方案将让当地专家参与定性研究活动，并将与当地社区机构合作，制定当地使用情况调查问题和实施战略。4. 评估NHBS系统。与疾病控制和预防中心的合作将提高该项目评估国家艾滋病毒行为监测数据收集和实施方法的地方质量、效率和价值的能力。

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 2008-2010. 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). The collected behavioral data will be used to inform local HIV prevention planning as well as to contribute to a national HIV behavioral surveillance database. The overall goal of this proposal is to obtain support to maintain an existing HIV behavioral surveillance system for monitoring of long-term trends in the prevalence of HIV risk behaviors among high-risk populations in Los Angeles County. Four specific aims have been identified to accomplish this goal: 1. Conduct annual behavioral surveys. The system will monitor the prevalence of HIV risk behaviors and access to and use of HIV prevention programs by administering standardized cross-sectional surveys to a minimum of 500 MSM, 500 IDU, and 500 heterosexuals at elevated risk of HIV infection in Los Angeles County. Time-space and respondent-driven sampling will be used to recruit participants for these surveys. 2. Offer HIV counseling and testing. Both rapid and standard HIV testing services will be offered to survey participants. HIV prevalence and HIV incidence estimates will be obtained for each risk population. 3. Collaborate with local partners. The HIV Epidemiology Program will engage local experts in qualitative research activities and will collaborate with local community agencies to develop local-use survey questions and implementation strategies. 4. Evaluate the NHBS system. Collaboration with the Centers for Disease Control and Prevention will enhance the program's ability to evaluate the local quality, efficiency, and value of national HIV behavioral surveillance data collection and implementation methods.
