African American men who have sex with men have been disproportionately affected by the HIV epidemic in the United States and remain to this day one of the groups with highest HIV prevalence and incidence. Our goal was to clarify the current state of HIV risk, sexual behaviors, and structural/network-network level factors that affect black MSM's population risk of HIV, enabling the formulation of targeted and up-to-date public health messages/campaigns directed at this vulnerable population. Our approach maximized the use of local data through a process of synthesis and triangulation of multiple independent and overlapping sources of information that are sometimes separately published and often not examined side-by-side. Among African American MSM, we observed stable HIV incidence despite increases in reported individual risk behavior and STDs. An increasing proportion of African American MSM are reporting HIV testing in the past 6 months and seroadaptive behaviors, which may play a role in this observed decline in HIV among MSM in San Francisco, California. Our analysis suggests that currently the HIV epidemic is stable among African American MSM in San Francisco. However, we suggest that the observed stability is due to factors prohibiting expansion of new infections rather than decreasing risks for HIV infection among African American MSM.
在美国，与男性发生性行为的非裔美国男性受艾滋病毒流行的影响尤为严重，至今仍是艾滋病毒患病率和发病率最高的群体之一。我们的目标是厘清艾滋病毒风险、性行为以及影响黑人男男性行为者群体艾滋病毒感染风险的结构/网络层面因素的现状，以便制定针对这一脆弱群体的有针对性的最新公共卫生信息/宣传活动。我们的方法通过综合和交叉验证多个独立且相互重叠的信息来源（这些信息来源有时单独发布，且常常未被并列审视），最大限度地利用了本地数据。在非裔美国男男性行为者中，尽管报告的个人风险行为和性传播感染有所增加，但我们观察到艾滋病毒发病率保持稳定。越来越多的非裔美国男男性行为者报告在过去6个月内进行了艾滋病毒检测以及采取了血清适应性行为，这可能是加利福尼亚州旧金山男男性行为者中观察到的艾滋病毒感染率下降的原因之一。我们的分析表明，目前旧金山非裔美国男男性行为者中的艾滋病毒流行态势稳定。然而，我们认为观察到的这种稳定性是由于阻止新感染扩散的因素所致，而非非裔美国男男性行为者中艾滋病毒感染风险的降低。
