目的：异性性传播的艾滋病毒感染率在非裔美国人中不成比例地高。艾滋病毒的传播是受性网络的特点，包括性伙伴关系的混合模式之间的亚群不同的患病率infection.Study Design：我们进行了横断面分析以前收集的数据从北卡罗来纳州人口为基础的病例对照研究。受访者是异性恋黑人男性和女性，他们要么最近报告过异性传播艾滋病毒感染（病例），要么从普通人群中随机选择（对照）。方法：受访者报告了他们自己和他们最近的3个性伴侣的教育和参与情况非法药物使用、同时存在的性伴侣和监禁。我们通过比较受访者报告的自己和他们报告的伴侣的特征和行为来检查性混合模式。我们估计纽曼的混合系数（-1.0至1.0）作为一个总的定量评估的混合patterns.Results：在4层（男性和女性的情况下，男性和女性的控制），混合是间接的（0.31-0.45）与非法药物的使用和最低限度的间接性方面有共同的合作伙伴（0.14-0.22）。监禁的混合模式对男性（0.18和0.41）来说是决定性的，但对女性（0.07和0.08）来说不是。混合教育方面的主要是男性controls.Conclusions（0.33）：这些性伙伴关系的模式，部分驱动的社会和经济背景下的非裔美国人的生活，可能有助于异性传播的艾滋病毒流行。
Objectives: Heterosexually transmitted HIV infection rates are disproportionately high among African Americans. HIV transmission is influenced by sexual network characteristics, including sexual partnership mixing patterns among subpopulations with different prevalences of infection.Study Design: We conducted a cross-sectional analysis of previously collected data from a North Carolina population-based case-control study. Respondents were heterosexual black men and women who either had recently reported heterosexually transmitted HIV infection (cases) or were randomly selected from the general population (controls).Methods: Respondents reported their own and their 3 most recent sex partners' education and involvement in illicit drug use, concurrent sex partners, and incarceration. We examined sexual mixing patterns by comparing the characteristics and behaviors of respondents reported for themselves with those they reported for their partners. We estimated Newman assortativity coefficient (-1.0 to 1.0) as an aggregate quantitative assessment of mixing patterns.Results: Across the 4 strata (male and female cases, male and female controls), mixing was assortative (0.31-0.45) with respect to illicit drug use and minimally assortative with respect to having concurrent partners (0.14-0.22). Mixing patterns for incarceration were assortative for men (0.18 and 0.41) but not women (0.07 and 0.08). Mixing with respect to education was assortative primarily for male controls (0.33).Conclusions: These sexual partnership patterns, driven in part by the social and economic context of life for African Americans, likely contribute to the heterosexually transmitted HIV epidemic.
