ASSESSING BEHAVIOR AMONG WOMEN AT HIGH RISK OF HIV

这项研究的主要目标是增加对这一问题的科学认识。 女性人口学特征和行为模式 妓女，特别是因为他们对异性传播的影响， 艾滋病和其他性传播疾病。 具体目标 包括（1）开发基于几何的尺寸估计， 大都市妓女人口的构成 地区（洛杉矶县）;（2）确定感染的流行率 人类免疫缺陷病毒（HIV）和其他性病， （3）衡量性暴力和与毒品有关的暴力的流行率 可以传播或有助于预防艾滋病毒传播的行为。 这项研究将采用列表抽样和区域概率相结合的方法 取样. 妓女将被随机抽样从帧， 对应不同的招揽方式， 卖淫和其他工作，嫖客人数及其一般情况 性行为的特点、性质和采取的预防措施 有客户和不付钱的性伴侣，静脉注射毒品史 使用和共用针头，性传播疾病史，以及 关于艾滋病和艾滋病传播的知识和信念， 预防 将分析血液样本中是否存在抗体， HIV-、HTLV-1和B型肝炎（表面抗体）。 梅毒血清学 将被执行。 样本观测值将按其采样的倒数进行加权 概率和结果的总和，以达到估计的大小 和妓女人口的构成。 艾滋病毒抗体状况和 将评估高危行为的流行率 人口和由招标方式定义的各种亚人口 （街头妓女、应召女郎等）。 观察将进一步 按报告的无保护性交行为频率加权 来描述异性恋男性客户的风险。 多变量分析 将进行评估血清阳性之间的关系， 另一方面是背景变量和风险行为。 生存分析技术将应用于妓女的详细情况 就业历史来分析职业转型模式。

The broad goal of this study is to increase scientific knowledge of the demographic characteristics and behavioral patterns of female prostitutes, especially as they bear on the heterosexual transmission of AIDS and other sexually transmitted diseases (STDs). Specific aims include (1) developing empirically-based estimated of the size and composition of the female prostitute population in a large metropolitan area (Los Angels County); (2) determining the prevalence of infection with human immunodeficiency virus (HIV) and other STDs in this population; and (3) measuring the prevalence of sexual and drug-related behaviors that can transmit or help prevent transmission of HIV. The study will employ a combination of list sampling and area probability sampling. Prostitutes will be randomly sampled from frames that correspond to different modes of solicitation, history of employment in prostitution and other jobs, numbers of clients and their general characteristics, nature of sexual acts performed and precautions taken with clients and nonpaying sexual partners, history of intravenous drug use and needle sharing, history of sexually transmitted diseases, and knowledge and beliefs regarding AIDS and AIDS transmission and prevention. Blood samples will be analyzed for presence of antibodies to HIV-, HTLV-1, and hepatitis B (surface antibodies). Syphilis serology will be performed. Sample observations will be weighted by the inverse of their sampling probabilities and the results summed to arrive at estimated of the size and composition of the prostitute population. HIV antibody status and the prevalence of high risk behaviors will be evaluated for this population and for various subpopulations defined by mode of solicitation (street prostitutes, call girls, etc.). Observations will be further weighted by reported frequency of unprotected acts of sexual intercourse to characterize risk to heterosexual male clients. Multivariate analyses will be carried out to estimate the relationship between seropositivity on the one hand and background variables and risk behaviors on the other. Techniques of survival analysis will be applied to prostitutes' detailed employment histories to analyze patterns of career transition.
