SEXUAL PARTNERSHIPS OF HIV-POSITIVE ADULTS IN THE UNITE*

描述（由申请人提供）：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只是最近才成为科学研究的一个经常性主题。艾滋病毒感染者之间的性关系模式是一个基本上没有得到研究的重要方面。 在这个项目中，研究人员将开发一个艾滋病毒阳性成年人的性关系的类型学，并研究如何关系模式与性风险和降低风险的行为。数据将来自风险和预防研究，该研究于1998年底从艾滋病毒费用和服务利用研究（HCSUS）抽取的1 421名成年人的全国概率样本中收集。具体目标是：（1）制定和应用一个分类方案，以描述艾滋病毒阳性成年人的性关系，包括性伙伴的数量以及关系的类型和同时发生的情况;（2）研究性关系模式如何因年龄、性别、性取向、种族/民族和生育/父母身份状况而有所不同;（3）研究关系持续时间和排他性如何与其他关系特征相关，如情感亲密度，吸毒和暴力;（4）测试不同关系类型在性风险和降低风险行为方面的差异，包括使用避孕套和避免肛交或阴道性交，以及相关行为，如向性伴侣透露艾滋病毒状况;（5）估计涉及伴侣选择的降低艾滋病毒风险策略在艾滋病毒阳性成年人中的流行程度，并检查这些策略的相关性;以及（6）检查关系模式（伴侣数量和关系并发性）与最近被诊断患有性传播疾病的自我报告之间的双变量和多变量关联。

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.
