Concurrent sexual partnerships may help to explain the disproportionately high prevalence of HIV and other sexually transmitted infections among African Americans. The persistence of such disparities would also require strong assortative mixing by race. We examined descriptive evidence from 4 nationally representative US surveys and found consistent support for both elements of this hypothesis. Using a data-driven network simulation model, we found that the levels of concurrency and assortative mixing observed produced a 2.6-fold racial disparity in the epidemic potential among young African American adults.
同时存在的性伴侣关系可能有助于解释非裔美国人中艾滋病毒和其他性传播感染的患病率高得不成比例的现象。这种差异的持续存在也需要强大的种族选择性混合。我们研究了来自4项具有全国代表性的美国调查的描述性证据,发现对这一假设的两个要素都有一致的支持。使用一个数据驱动的网络模拟模型,我们发现观察到的性伴侣关系并发水平和选择性混合在年轻非裔美国成年人的流行潜力中产生了2.6倍的种族差异。
