National HIV Behavioral Surveillance among MSM, IDUs and Heterosexuals in Houston

项目概要/摘要 休斯顿是美国第四大城市，艾滋病感染率在美国排名第八。 国家在过去的29年里，自从休斯顿报告了第一例艾滋病病例以来， 艾滋病毒感染率仍然很高，特别是在少数民族人口中。三 主要的高危人群是男男性行为者（MSM）、注射吸毒者 (IDU)以及生活在艾滋病高发地区的异性恋者。休斯顿成 通过疾病预防控制中心直接资助艾滋病毒预防，并有责任监测 通过行为监测来控制艾滋病的流行。在过去的七年里，休斯顿 国家艾滋病毒行为监测项目（NHBS）。等 监测对于确保艾滋病毒预防职能解决 最高风险人群的适当行为，以及预防工作 具有改变危险行为的预期效果，这些行为使人们面临更大的风险， 艾滋病。 我们研究的具体目的是建立一个持续的艾滋病毒行为监测 该计划旨在：1）确定艾滋病毒危险行为的流行率和趋势 男男性行为者、注射吸毒者、有感染艾滋病毒风险的异性恋者和男对女 跨性别个体（TG）; 2）描述所有人群中HIV的血清阳性率， 和HCV在IDU人群中的血清阳性率，以及3）评估获得， 艾滋病毒预防服务和艾滋病毒检测， 人口。 将使用基于场所的MSM周期抽样招募参与者， IDU、HET和TG周期的受访者驱动采样。我们将使用标准化的 NHBS方案和核心问卷;将收集有关当地 预防方案。将提供自愿的艾滋病毒快速检测，以确定血清- 艾滋病毒在目标人群中的流行率。额外的丙型肝炎检测将 提供给IDU人群。从NHBS收集的数据将用于描述关键指标的趋势。 行为风险指标，并评估目前的艾滋病毒预防计划。这些信息 可用于确定预防服务的差距，并针对新的预防活动， 减少休斯顿新的艾滋病毒感染的目标。

Project Summary/Abstract Houston is the 4th largest city in the US, and has the 8th highest HIV rates in the country. In the past 29 years since the first AIDS case was reported in Houston, rates of HIV infection have remained high, especially among minority populations. The three main at-risk populations are men who have sex with men (MSM), injection drug users (IDU), and heterosexuals living in areas of high HIV prevalence (HET). Houston is directly funded for HIV prevention through the CDC, and has a responsibility to monitor the HIV epidemic through behavioral surveillance. For the past seven years Houston has been part of the National HIV Behavioral Surveillance (NHBS) project. Such surveillance is important to ensure that HIV prevention functions address the appropriate behaviors among the highest risk populations, and that prevention efforts have the desired effect of changing risky behaviors that place people at increased risk of HIV. The specific aims of our study are to develop an ongoing HIV behavioral surveillance program designed to: 1) ascertain the prevalence of, and trends in, HIV risk behaviors among MSM, IDUs, heterosexuals at risk for HIV infection and male to female transgender individuals (TG); 2) describe the seroprevalence of HIV in all populations, and the seroprevalence of HCV among the IDU population, and 3) to assess the access to, and utilization of, HIV prevention services and HIV testing among these high risk populations. Participants will be recruited using venue-based sampling for the MSM cycles and respondent driven sampling for the IDU, HET and TG cycles. We will use the standardized NHBS protocol and core questionnaire; additional information will be collected about local prevention programs. Voluntary rapid HIV testing will be offered to determine the sero- prevalence of HIV among the target populations. Additional Hepatitis C testing will be offered to IDU population. Data collected from NHBS will be used to describe trends in key behavioral risk indicators and evaluate current HIV prevention programs. This information can be used to identify gaps in prevention services and target new prevention activities with the goal of reducing new HIV infections in Houston.
