To determine how heterosexuals at risk for HIV infection interconnect in social networks and how such relationships affect HIV transmission.
Cross-sectional study with face-to-face interviews to ascertain sociosexual connections; serologic testing.
Prostitute women (n = 133), their paying (n = 129) and non-paying (n = 47) male partners; injecting drug users (n = 200) and their sex partners (n = 41). Participants were recruited in sexually transmitted disease and methadone clinics, an HIV-testing site, and through street outreach in Colorado Springs, Colorado, USA.
Reported behaviors, risk perceptions, sociosexual linkages, and HIV prevalence.
Respondents were well informed, but reported engaging in high-risk behaviors frequently. Nevertheless, over 70% of respondents perceived themselves to be at low risk for HIV infection. The 595 respondents identified a social network of 5162 people to which they belonged. Network analytic methods indicated 147 separate connected components of this network; eight of the 19 HIV-positive individuals in the network were located in smaller components remote from the largest connected component.
The isolated position of HIV-positive individuals may serve as a barrier to HIV transmission and may account for the lack of diffusion of HIV in heterosexual populations in this region. Network analysis appears useful for understanding the dynamics of disease transmission and warrants further development as a tool for intervention and control.
确定有感染艾滋病毒风险的异性恋者在社交网络中的联系方式，以及此类关系如何影响艾滋病毒传播。
采用面对面访谈的横断面研究以确定社会性接触；进行血清学检测。
妓女（n = 133）、她们的付费男性伴侣（n = 129）和非付费男性伴侣（n = 47）；注射吸毒者（n = 200）及其性伴侣（n = 41）。参与者是在美国科罗拉多州科罗拉多斯普林斯的性传播疾病诊所、美沙酮诊所、一个艾滋病毒检测点以及通过街头宣传招募的。
报告的行为、风险认知、社会性接触以及艾滋病毒感染率。
受访者了解情况，但报告称经常从事高风险行为。然而，超过70%的受访者认为自己感染艾滋病毒的风险较低。595名受访者确定了一个他们所属的由5162人组成的社交网络。网络分析方法表明该网络有147个独立的连通分支；网络中19名艾滋病毒阳性个体中有8人位于远离最大连通分支的较小分支中。
艾滋病毒阳性个体的孤立位置可能成为艾滋病毒传播的障碍，并可能解释了该地区异性恋人群中艾滋病毒缺乏传播的原因。网络分析似乎有助于理解疾病传播的动态过程，作为一种干预和控制工具值得进一步发展。
