Human immunodeficiency virus (HIV) disproportionately affects men who have sex with men (MSM) in the United States. Most prior research into drivers of HIV transmission has focused on individual characteristics rather than on dyadic-level behaviors such as sex partner selection. This article explores racial/ethnic preferences in sex and relationship partner selection among MSM to further contextualize the spread of HIV within minority groups.
Participants were recruited through a mobile application (app) for men to meet other men in 2015 and completed an online survey on behaviors related to HIV risk. All analyses on the sample of 530 MSM were conducted in 2015.
There was significant homophily in partner selection within racial/ethnic minorities, but not for white MSM. In general, mobile app-using MSM reported a general preference for white and Hispanic men and a dispreference for black and Asian men, both for sex and relationship partners.
Racial/ethnic preferences were found to drive intentions to form partnerships within this sample. Combined with the stigma many of these racial/ethnic minorities may also feel from homophobic attitudes within their own racial/ethnic communities, these MSM may be at particular risk for social isolation. These partner preferences likely affect the structure of the sexual networks of MSM and may contribute to increased clustering within high HIV incident sexual networks.
在美国,人类免疫缺陷病毒(HIV)在男男性行为者(MSM)中不成比例地流行。大多数先前关于 HIV 传播驱动因素的研究都集中在个体特征上,而不是在性伴侣选择等对偶级行为上。本文探讨了 MSM 中在性和伴侣选择方面的种族/民族偏好,以进一步说明 HIV 在少数群体中的传播。
参与者是通过一个针对男性的移动应用程序(app)在 2015 年招募的,他们完成了一项关于与 HIV 风险相关的行为的在线调查。对 530 名 MSM 样本的所有分析均于 2015 年进行。
在少数族裔内部,伴侣选择存在显著的同质性,但对于白人 MSM 则不然。总的来说,使用移动应用程序的 MSM 报告说,他们普遍更喜欢白人男性和西班牙裔男性,而不喜欢黑人男性和亚裔男性,无论是性伴侣还是关系伴侣。
在本样本中发现,种族/民族偏好会影响建立伴侣关系的意图。结合这些少数族裔可能在自己的种族/族裔社区中也因恐同态度而感到的耻辱,这些 MSM 可能特别面临社会孤立的风险。这些伴侣偏好可能会影响 MSM 的性网络结构,并可能导致高 HIV 发生率的性网络内的聚类增加。
