BEHAVIORAL SURVEILLANCE PROJECT

描述（由申请人提供）：简介：国家艾滋病行为监测（NHBS）系统监测艾滋病毒感染高危人群的特定行为和艾滋病毒流行率和发病率。佛罗里达州卫生部艾滋病毒/艾滋病局（BHA）致力于在迈阿密大都会统计区（MSA）的迈阿密站点（迈阿密-戴德县）继续开展国家卫生和保健服务活动。来自该领域的国家卫生统计局数据对于有效指导和评估地方、州和国家层面的艾滋病毒预防活动至关重要。迈阿密地区的艾滋病流行率在msa和有资格获得国家卫生和社会保障局资助的地区中排名第五（截至2004年底有12,192名艾滋病患者）。背景/目标：国家卫生和公众服务系统于2002年首次获得资助，以支持由疾病预防控制中心和美国卫生与公众服务部于2000年确立的若干公共卫生目标。我们的目标是在艾滋病毒感染高风险的成年人中进行横断面调查；采用最先进的抽样方法（即以受访者为导向和以地点为基础的时空抽样）；并在资助期内每年对至少500名符合条件的参与者进行调查和自愿进行艾滋病毒检测。国家卫生统计局的活动将提供有关使人们面临感染艾滋病毒风险的性行为和吸毒风险行为的数据；艾滋病毒流行率和发病率；艾滋病毒检测模式；以及艾滋病毒检测和其他预防服务的获取、利用和影响。方法：BHA将继续与迈阿密大学（UM）合作，在迈阿密开展NHBS。BHA和UM将根据CDC多站点协议和指令实施NHBS，并准备使用以下描述的方法进行研究。每年，工作人员将交替调查目标人群（即男男性行为者（MSM）、注射吸毒者（IDUs）和有感染艾滋病毒风险的异性恋者（HET））。在每个周期取样之前，工作人员将进行形成性评估活动，以确定感兴趣的人群，确定接触人群的方式，并深入了解人群的艾滋病毒风险行为。研究小组将与不同的社区伙伴（例如研究人员、服务提供者）合作，进行形成性研究，并在完成抽样和数据分析后传播研究结果。

Description (provided by applicant): Introduction: The National HIV Behavioral Surveillance (NHBS) system monitors selected behaviors and HIV prevalence and incidence among populations at high risk for HIV infection. The Florida Department of Health, Bureau of HIV/AIDS (BHA) is committed to continuing NHBS activities in the Miami site (Miami-Dade County) of the Miami Metropolitan Statistical Area (MSA). NHBS data from this area are imperative to effectively guide and evaluate HIV prevention activities on local, state, and national levels. The Miami division had the fifth highest AIDS prevalence (12,192 persons living with AIDS at the end of 2004) among MSAs and locales eligible for NHBS funding. Background/Objectives: NHBS was first funded in 2002 to support a number of public health goals established in 2000 by the CDC and the U.S. Department of Health and Human Services. Our objectives are to conduct a cross-sectional survey among adults at high risk for HIV infection; to employ state-of-the-art sampling methodologies (i.e., respondent-driven and venue based, time-space sampling); and to survey and conduct voluntary HIV testing among a minimum of 500 eligible participants each year of the funding period. NHBS activities will provide data on sexual and drug-use risk behaviors that place people at risk for HIV infection; HIV prevalence and incidence; HIV testing patterns; and access to, utilization of, and impact of HIV testing and other prevention services. Methods: The BHA will continue to collaborate with the University of Miami (UM) to conduct NHBS in Miami. The BHA and UM will implement NHBS according to CDC multisite protocols and directives and are prepared to conduct the study with the methods described hereafter. Each year, staff will alternate the survey target population (i.e., men who have sex with men [MSM], injection drug users [IDUs], and heterosexuals at risk for HIV infection [HET]). Prior to sampling in each cycle, staff will conduct formative assessment activities to define the population of interest, determine ways to access the population, and gain insight into the population's HIV risk behaviors. The research team will collaborate with various community partners (e.g., researchers, service providers) both to perform formative research and to disseminate findings after completing sampling and data analysis. Conclusions: The BHA and UM research team has successfully obtained a sample of > 500 eligible persons in all previous NHBS cycles in Miami and has the experience, expertise, and valuable resources (e.g., a mobile interviewing van) to continue successful NHBS activities. Marlene LaLota, MPH, Principal Investigator, and Lisa Metsch, PhD, Co-Principal Investigator, together hold over 30 years of experience directing HIV prevention studies and each have a wealth of peer-reviewed publications. David Forrest, PhD, Field Operations Director, is a trained cultural anthropologist and brings ethnographic expertise to NHBS operations, including formative research activities. The team has an established history of close collaboration within the group and with CDC to plan and conduct NHBS activities. Lastly, the team is fully committed to disseminating study findings on local, state, and national levels and using the data to evaluate and improve HIV prevention services.
