大量未确诊的直肠性传播感染表明，在黑人男同性恋、双性恋和其他与男性发生性关系的男性中，筛查仍然不够充分。

OBJECTIVE
To better understand rectal STI screening practices for Black gay, bisexual and other men who have sex with men (BGBMSM).
FINDINGS
Although 15% of BGBMSM lab tested positive for a rectal STI, the majority of these (94%) were asymptomatic. Though all participants reported their status as HIV negative/unknown, 31 of 331 (9.4%) tested positive on HIV rapid tests. Neither condomless anal intercourse nor the number of male sex partners was associated with rectal STI or HIV diagnosis, although rectal STI diagnosis was positively related to testing HIV positive.
CONCLUSIONS
Findings suggest that substantial numbers of BGBMSM have asymptomatic STIs but are not tested-an outcome that is likely a strong driver of onward HIV acquisition. Therefore, we must address the asymptomatic STI epidemic among GBMSM in order to reduce HIV transmission, as well as temper STI transmission, among this key population.
目的
更好地了解黑人男同性恋、双性恋和其他与男性发生性关系的男性（BGBMSM）的直肠性传播感染筛查实践。
发现
尽管 15%的 BGBMSM 实验室检测出直肠性传播感染呈阳性，但其中大多数（94%）无症状。尽管所有参与者均报告其 HIV 阴性/未知，但在 331 名参与者中，有 31 名（9.4%）HIV 快速检测呈阳性。虽然无保护的肛交和性伴侣的数量与直肠性传播感染或 HIV 诊断无关，但直肠性传播感染的诊断与 HIV 阳性检测呈正相关。
结论
研究结果表明，大量的 BGBMSM 患有无症状性传播感染，但未接受检测——这很可能是 HIV 进一步传播的主要原因。因此，我们必须解决男同性恋、双性恋和其他与男性发生性关系的男性中的无症状性传播感染流行问题，以减少 HIV 传播，并遏制这一关键人群中的性传播感染传播。
