Baltimore, Philadelphia, and Washington, DC are geographically proximate cities with high HIV prevalence, including among black men who have sex with men (BMSM). Using data collected among BMSM in CDC's National HIV Behavioral Surveillance project, we compared socio-demographic characteristics, HIV risk behaviors, and service utilization to explore similarities and differences that could inform local and regional HIV intervention approaches.
BMSM were recruited through venue time location sampling, June-December, 2011. Participants completed identical socio-behavioral surveys and voluntary HIV testing. Analyses were conducted among the full sample and those aged 18-24.
Participants included 159 (DC), 364 (Baltimore), and 331 (Philadelphia) eligible BMSM. HIV prevalence was 23.1% (DC), 48.0% (Baltimore), 14.6% (Philadelphia) with 30.6%, 69.0%, 33.3% unrecognized HIV infection, respectively. Among BMSM 18-24, HIV prevalence was 11.1% (DC), 38.9% (Baltimore), 9.6% (Philadelphia) with unrecognized HIV infection 0.0%, 73.8%, 60.0% respectively. Compared with the other 2 cities, Baltimore participants were less likely to identify as gay/homosexual; more likely to report unemployment, incarceration, homelessness, sex exchange; and least likely to use the internet for partners. DC participants were more likely to have a college degree and employment. Philadelphia participants were more likely to report gay/homosexual identity, receptive condomless anal sex, having only main partners, and bars/clubs as partner meeting places. Sexually transmitted disease testing was universally low.
Analyses showed especially high HIV prevalence among BMSM in Baltimore including among young BMSM. Socio-demographic characteristics and HIV infection correlates differed across cities but unrecognized HIV infection and unknown partner status were universally high.
巴尔的摩、费城和华盛顿特区地理位置相近，艾滋病毒流行率较高，在与男性发生性关系的黑人男性（BMSM）中亦是如此。利用美国疾病控制与预防中心国家艾滋病毒行为监测项目中收集的BMSM数据，我们比较了社会人口学特征、艾滋病毒风险行为和服务利用情况，以探索可能为地方和区域艾滋病毒干预方法提供信息的异同点。
2011年6月至12月，通过场所时间地点抽样招募BMSM。参与者完成相同的社会行为调查和自愿艾滋病毒检测。对全样本以及年龄在18 - 24岁的参与者进行分析。
参与者包括159名（华盛顿特区）、364名（巴尔的摩）和331名（费城）符合条件的BMSM。艾滋病毒流行率分别为23.1%（华盛顿特区）、48.0%（巴尔的摩）、14.6%（费城），未被识别的艾滋病毒感染率分别为30.6%、69.0%、33.3%。在18 - 24岁的BMSM中，艾滋病毒流行率分别为11.1%（华盛顿特区）、38.9%（巴尔的摩）、9.6%（费城），未被识别的艾滋病毒感染率分别为0.0%、73.8%、60.0%。与其他两个城市相比，巴尔的摩的参与者较少认同自己为同性恋；更有可能报告失业、被监禁、无家可归、性交易；使用互联网寻找伴侣的可能性最小。华盛顿特区的参与者更有可能拥有大学学位和工作。费城的参与者更有可能报告同性恋身份、接受无保护肛交、只有主要伴侣以及将酒吧/俱乐部作为伴侣结识场所。性传播疾病检测率普遍较低。
分析显示，巴尔的摩的BMSM中艾滋病毒流行率尤其高，包括年轻的BMSM。不同城市的社会人口学特征和艾滋病毒感染相关因素有所不同，但未被识别的艾滋病毒感染和未知伴侣状况普遍较高。
