Using the Internet to meet sexual partners is associated with increased HIV risk behavior, including substance use, sex with multiple or anonymous partners, and unprotected anal sex (UAS), among diverse samples of MSM, yet little is known about Internet use and HIV risk among Black MSM specifically. In 2008, a sample of 197 Black MSM completed an interviewer-administered assessment and voluntary HIV counseling and testing. One fifth of the sample (20 %) reported meeting a sexual partner via the Internet in the past 12 months. Men who met sexual partners over the Internet had significantly more male sex partners (M = 13.44, SD = 20.01) than men who did not meet partners in this manner (M = 4.11, SD = 4.14, p < 0.001) and reported significantly higher rates of UAS (p < 0.05). Adjusting for sociodemographic and other HIV-related covariates, factors significantly associated with the increased odds of engaging in at least one episode of UAS with a male partner in the past 12 months included: meeting sexual partners on the Internet, identifying as gay, and lower knowledge about HIV transmission. These findings highlight the unique HIV risk behaviors among Black MSM meeting sexual partners via the Internet and warrant tailoring of prevention activities to address the specific behaviors and social influences that may contribute to increased HIV spread among this population.
利用互联网寻找性伴侣与增加艾滋病毒风险行为相关,包括物质使用、与多个或匿名伴侣发生性行为以及无保护的肛交(UAS),这些行为在不同的男男性行为者(MSM)样本中都有出现,但对于黑人男男性行为者(Black MSM)具体的互联网使用和艾滋病毒风险情况却知之甚少。2008 年,197 名黑人男男性行为者完成了一次由访谈者管理的评估和自愿艾滋病毒咨询和检测。五分之一(20%)的参与者在过去 12 个月内通过互联网结识性伴侣。通过互联网结识性伴侣的男性与没有通过这种方式结识性伴侣的男性相比,有更多的男性性伴侣(M=13.44,SD=20.01),差异具有统计学意义(M=4.11,SD=4.14,p<0.001),且报告 UAS 的比例显著更高(p<0.05)。在调整了社会人口学和其他与艾滋病毒相关的协变量后,与过去 12 个月内至少有一次与男性伴侣发生 UAS 的可能性增加显著相关的因素包括:通过互联网结识性伴侣、认同同性恋,以及对艾滋病毒传播的了解较少。这些发现强调了通过互联网寻找性伴侣的黑人男男性行为者的独特艾滋病毒风险行为,需要针对这些行为和可能导致该人群艾滋病毒传播增加的社会影响,制定有针对性的预防措施。
