背景：许多研究发现，非裔美国人的特定性传播疾病发病率相对较高，通常是白人和其他种族/族裔群体的10至20倍，但没有令人信服的解释。目的：本研究试图利用具有全国代表性的概率样本和网络方法的数据来解决这一难题。国家健康和社会生活调查（NHSLS）是美国1511名男性和1921名女性的全国代表性概率样本。对这些数据进行逻辑回归分析，可以对与性传播疾病相关的个体风险因素进行多变量分析。通过对数分析和模拟，我们还确定了种族/民族内部和之间的性网络模式的影响。结果：对NHSLS进行的Logistic回归分析显示，即使在控制了所有适当的个人层面风险因素后，非洲裔美国人感染细菌性疾病的可能性几乎是其他种族/族裔群体的五倍。结论:非裔美国人较高的细菌性疾病感染率可以用不同种族/民族群体内部和之间的性网络模式来解释，首先，感染在整个非裔美国人中更为普遍，因为伴侣选择更具高度的混乱性——这意味着“边缘”非裔美国人（过去一年只有一个伴侣）选择“核心”非裔美国人（过去一年有四个或更多伴侣）的可能性是“边缘”白人选择“核心”白人的五倍。性传播疾病在非裔美国人中仍然存在，因为他们的伴侣选择比其他群体更隔离（选择性交配）。仅仅因为这个因素，非裔美国人感染性传播疾病的可能性是白人的1.3倍。
Background: Many studies have observed that African Americans have comparatively high rates of selected STDs, often 10 to 20 times higher than whites and other racial/ethnic groups, but without convincing explanation,Goal: This study attempts to solve this puzzle using data from a nationally representative probability sample and a network approach,Study design: The National Health and Social Life Survey (NHSLS) is a nationally representative probability sample of 1,511 men and 1,921 women in the United States. Logistic regression analysis of these data permit a multivariate analysis of the individual risk factors associated with STDs, Using loglinear analysis and a simulation, we also identify the effects of sexual network patterns within and between racial/ethnic groups.Results: Logistic regression analysis of the NHSLS re revealed, even after controlling for all the appropriate individual-level risk factors, that African Americans are almost five times more likely to be infected by bacterial diseases than the other racial/ ethnic groups.Conclusions: African Americans' higher infection rate for bacterial diseases can be explained by the patterns of sexual networks within and between different racial/ethnic groups, First, infections are more widespread in the African American population at large because partner choice is more highly dissortative-meaning that "peripheral'' African Americans (who have had only one partner in the past gear) are five times more likely to choose "core' African Americans (who have had four or more partners in the past year) than "peripheral" whites are to choose "core" whites, Secondly, sexually transmitted infections stay within the African American population because their partner choices are more segregated (assortative mating) than other groups. The likelihood of African Americans having a sexually transmitted infection is 1.3 times greater than it is for whites because of this factor alone.
