SEXUAL PARTNERSHIPS OF HIV-POSITIVE ADULTS IN THE UNITE*

描述(申请人提供)：艾滋病毒感染者现在被认为是艾滋病毒预防工作的重要目标人群。不幸的是，艾滋病毒阳性者的性行为直到最近才经常成为科学研究的主题。艾滋病毒携带者之间的性关系模式是一个很大程度上仍未被研究的重要方面。 在这个项目中，研究人员将开发艾滋病毒阳性成年人的性关系类型，并检查关系模式与性风险和降低风险行为的关系。数据将来自风险与预防研究，该研究于1998年底从全国1,421名成年人的概率样本中收集，这些样本来自艾滋病毒成本和服务利用研究(HCSUS)。具体目的是：(1)制定和应用分类方案，根据伴侣的数量以及关系的类型和同时发生的情况来描述艾滋病毒阳性成年人的性关系；(2)检验性关系模式如何随年龄、性别、性取向、种族/民族以及生育/为人父母的状况而变化；(3)检视关系持续时间和排他性如何与其他关系特征有关，例如情感亲密、吸毒和暴力；(4)测试性风险和降低风险行为(包括使用避孕套和避免肛交或阴道性交)以及相关行为(如向性伴侣披露艾滋病毒状况)方面的关系类型之间的差异；(5)估计艾滋病毒阳性成年人中涉及选择伴侣的艾滋病毒降低风险策略的流行率，并检查这些策略的相关性；以及(6)检查关系模式(伴侣数量和关系的并存)与最近被诊断为患上性传播疾病的自我报告之间的双变量和多变量关系。

DESCRIPTION (provided by applicant): People living with HIV infection are now recognized as an important target population for HIV prevention efforts. Unfortunately, the sexual behavior of HIV-positive persons has only recently become a frequent subject for scientific study. One important aspect that remains largely unstudied is the pattern of sexual relationships among people living with HIV. In this project, investigators will develop a typology of the sexual relationships of HIV-positive adults and examine how relationship patterns are related to sexual risk and risk-reduction behaviors. Data will come from the Risk & Prevention Study, collected in late 1998 from a national probability sample of 1,421 adults drawn from the HIV Cost and Services Utilization Study (HCSUS). The specific aims are to: (1) Develop and apply a classification scheme for describing the sexual relationships of HIV-positive adults in terms of number of partners and type and concurrency of relationships; (2) examine how sexual relationship patterns vary by age, gender, sexual orientation, race/ethnicity, and fertility/parenthood status; (3) examine how relationship duration and exclusivity are related to other relationship characteristics, such as emotional closeness, drug use, and violence; (4) test for differences between relationship types in sexual risk and risk reduction behaviors, including condom use and avoidance of anal or vaginal intercourse, and in related behaviors, such as disclosure of HIV status to sexual partners; (5) estimate the prevalence among HIV-positive adults of HIV risk-reduction strategies that involve partner selection, and examine the correlates of these strategies; and (6) examine the bivariate and multivariate associations between relationship patterns (number of partners and concurrency of relationships) and self-reports of having been recently diagnosed with a sexually transmitted disease.
