In the United States, black men who have sex with men (BMSM) are disproportionately affected by the HIV epidemic. The elevated estimates of HIV among BMSM suggest that to slow rates of HIV infections, a range of factors that may contribute to transmission must be researched. Use of online venues for seeking out sex partners is one such area that may further advance our understanding of risks for HIV among BMSM.
Black men who have sex with men residing in Atlanta, GA, reporting HIV-negative/unknown status completed survey assessments and HIV antibody testing. Logistic regression using generalized linear modeling was used to conduct both bivariate and multivariable analyses of psychosocial variables-that is, substance use, sexually transmitted infection symptoms/diagnoses, sexual risk behavior, online sex partner meeting, and HIV test results.
Two hundred thirty-two BMSM tested HIV negative and 39 BMSM tested HIV positive (14% new diagnoses). Reporting symptoms of a rectal sexually transmitted infection (odds ratio, 4.28; 95% confidence interval, 1.06-15.41) and use of sexual networking apps (odds ratio, 2.15; 95% confidence interval, 1.06-4.36) were both associated with testing HIV positive in a multivariable analysis.
The use of sexual networking apps is associated with risks for HIV infection above and beyond what is captured by sexual risk behavior alone. Evaluating how sexual networking apps affect sexual networks and social norms regarding sexual risk taking and HIV transmission is an important and novel area for HIV prevention and intervention development.
在美国，男男性行为的黑人（BMSM）受艾滋病毒流行的影响尤为严重。BMSM中艾滋病毒感染率较高，这表明为减缓艾滋病毒感染率，必须研究一系列可能导致传播的因素。利用在线平台寻找性伴侣就是这样一个领域，它可能会进一步增进我们对BMSM中艾滋病毒感染风险的理解。
居住在佐治亚州亚特兰大市、报告艾滋病毒阴性/状况不明的男男性行为黑人完成了调查评估和艾滋病毒抗体检测。使用广义线性模型的逻辑回归对心理社会变量进行双变量和多变量分析，这些变量包括物质使用、性传播感染症状/诊断、性风险行为、在线性伴侣会面以及艾滋病毒检测结果。
232名BMSM艾滋病毒检测呈阴性，39名BMSM艾滋病毒检测呈阳性（14%为新诊断病例）。在多变量分析中，报告直肠性传播感染症状（比值比，4.28；95%置信区间，1.06 - 15.41）和使用性网络应用程序（比值比，2.15；95%置信区间，1.06 - 4.36）均与艾滋病毒检测呈阳性相关。
使用性网络应用程序与艾滋病毒感染风险相关，这种风险超出了仅由性风险行为所反映的范围。评估性网络应用程序如何影响性网络以及关于性风险行为和艾滋病毒传播的社会规范，是艾滋病毒预防和干预发展的一个重要且新颖的领域。
