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

项目摘要/摘要 休斯顿是美国第四大城市，艾滋病毒感染率在全球排名第八 国家。自休斯敦报告第一例艾滋病病例以来的29年里， 艾滋病毒感染率居高不下，特别是在少数群体中。三位一体 主要高危人群是男男性行为者(MSM)、注射吸毒者 (IDU)，以及生活在艾滋病毒高流行地区的异性恋者。休斯顿是 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 通过行为监测控制艾滋病毒流行。在过去的七年里，休斯顿一直在 是国家艾滋病毒行为监测项目的一部分。是这样的 监测对于确保艾滋病毒预防职能解决 高危人群中的适当行为，以及预防努力 有预期的效果，改变使人们面临更高风险的危险行为 爱滋病毒。 我们研究的具体目标是发展一种持续的艾滋病毒行为监测 旨在：1)确定艾滋病毒危险行为的流行率和趋势 在男男性接触者、注射吸毒者、有感染艾滋病毒风险的异性恋者和男性与女性之间 变性人(TG)；2)描述艾滋病毒在所有人群中的血清阳性率， 以及注射吸毒者中丙型肝炎病毒的血清阳性率，以及3)评估获得， 在这些高风险中，艾滋病毒预防服务和艾滋病毒检测的使用 人口。 参与者将通过以场地为基础的男男性接触者周期抽样和 受访者驱动的IDU、HET和TG周期采样。我们将使用标准化的 NHBS协议和核心问卷；将收集有关当地的其他信息 预防计划。将提供自愿快速艾滋病毒检测，以确定血清- 艾滋病毒在目标人群中的流行情况。额外的丙型肝炎检测将是 提供给吸毒者。从NHBS收集的数据将用于描述关键 行为风险指标，并评估当前的艾滋病毒预防计划。此信息 可用于确定预防服务中的差距，并针对新的预防活动 减少休斯敦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.
