To develop a preliminary epidemiological description of a men who have sex with men (MSM) "POZ Party," an emerging sex environment for HIV+ MSM.
As part of a pilot study in New York City in 2003, data were collected using a brief, behavioural intercept survey at entry to POZ Party events. Domains include demographic characteristics, history of HIV infection, motivations for attending POZ parties, lifetime and recent exposure to drugs (including use during POZ Party events), and recent sexual practices (both within both POZ Party venues as well as in non-POZ Party venues).
Predominantly white and over the age of 30, subjects in the sample include a broad range of years living with HIV infection. Motivations for using a POZ Party venue for sexual partnering include relief from burdens for serostatus disclosure, an interest in not infecting others, and opportunities for unprotected sexual exchange. High rates of unprotected sex with multiple partners are prevalent in the venue. Although the sample evidences high rates of lifetime exposure to illicit drugs, relatively little drug use was reported in these sexual environments. These reports are consistent with evidence from direct observation at the venues themselves, in which no drug use was apparent.
Serosorting among HIV+ MSM may reduce new HIV infections, a stated interest of both POZ Party organisers and participants alike. However, high rates of unprotected anal intercourse within these venues signal continued risk for STIs. Additionally, unprotected sexual contact with HIV partners and status unknown partners outside POZ Party venues heightens concern for diffusion of HIV superinfection.
对男男性行为者（MSM）“艾滋派对”进行初步的流行病学描述，这是一种新出现的、针对感染HIV的MSM的性环境。
作为2003年纽约市一项试点研究的一部分，在进入艾滋派对活动时，通过简短的行为拦截调查收集数据。调查领域包括人口统计学特征、HIV感染史、参加艾滋派对的动机、终生及近期药物暴露情况（包括在艾滋派对活动期间的使用情况）以及近期性行为（包括在艾滋派对场所内和非艾滋派对场所内的性行为）。
样本中的受试者主要为白人，年龄在30岁以上，感染HIV的年限范围广泛。选择在艾滋派对场所进行性伴交往的动机包括减轻血清学状态披露的负担、不想感染他人以及无保护性交的机会。该场所内与多个性伴进行无保护性行为的比例很高。尽管样本显示终生非法药物暴露率很高，但在这些性环境中报告的药物使用相对较少。这些报告与在场所内直接观察的证据一致，在场所内未发现明显的药物使用情况。
感染HIV的MSM之间的血清型分类可能会减少新的HIV感染，这是艾滋派对组织者和参与者共同宣称的目标。然而，这些场所内无保护肛交的高比例表明性传播感染的风险依然存在。此外，在艾滋派对场所以外与HIV感染状况已知和未知的性伴进行无保护性接触增加了HIV重复感染传播的担忧。
