Regular human immunodeficiency virus (HIV) testing of persons at risk is critical to HIV prevention. Infrequent HIV testing and late diagnosis of HIV infection have been observed among young black men who have sex with men (MSM) and transwomen (transgender women)-two groups overrepresented in the HIV epidemic.
The objective of this study was to inform the development of a brief mobile phone intervention to increase HIV testing among young black MSM and transwomen by providing a tailored recommendation of an optimal HIV testing approach. We identified demographic, behavioral, psychosocial, and sociostructural factors associated with intentions to use three specific HIV testing approaches: self-testing, testing at a clinic or other provider, and couples HIV testing and counseling (CHTC).
Individuals were eligible for a Web-based survey if they were male at birth; were between the ages of 16 and 29 years; self-identified as black, African American, Caribbean black, African black, or multiethnic black; were not known to be HIV-infected; and reported insertive or receptive anal intercourse with a man or transwoman in the last 12 months. Recruitment occurred via banner advertisements placed on a range of social and sexual networking websites and apps in New York City and nationally, and via events attended by young black MSM and transwomen in New York City. Intention to test by each testing method was analyzed using logistic regression with best subset models and stepwise variable selection.
Among 169 participants, intention to use a self-test was positively associated with comfort in testing by a friend or a partner at home (Adjusted odds ratio, AOR, 2.40; 95% CI 1.09-5.30), and stigma or fear as a reason not to test (AOR 8.61; 95% CI 2.50-29.68) and negatively associated with higher social support (AOR 0.48; 95% CI 0.33-0.72) and having health insurance (AOR 0.21; 95% CI 0.09-0.54). Intention to test at a clinic or other provider was positively associated with self-efficacy for HIV testing (AOR 2.87; 95% CI 1.48-5.59) and social support (AOR 1.98; 95% CI 1.34-2.92), and negatively associated with a lifetime history of incarceration (AOR 0.37; 95% CI 0.16-0.89). Intention to test by CHTC was negatively associated with higher educational level (Some college or Associate's degree vs high school graduate or less [AOR 0.81; 95% CI 0.39-1.70]; Bachelor's degree or more vs high school graduate or less [AOR 0.28; 95% CI 0.11-0.70]).
Unique factors were associated with intention to test using specific testing approaches. These data will be critical for the development of a tailored intervention that shows promise to increase comfort and experiences with a variety of testing approaches among young black MSM and transwomen.
对高危人群进行定期的人类免疫缺陷病毒(HIV)检测对HIV预防至关重要。在男男性行为者(MSM)和跨性别女性(变性女性)这两类在HIV疫情中占比过高的群体中,观察到HIV检测频率较低以及HIV感染诊断较晚的情况。
本研究的目的是通过提供针对最佳HIV检测方法的个性化建议,为开发一种简短的手机干预措施提供信息,以增加年轻黑人男男性行为者和跨性别女性的HIV检测。我们确定了与使用三种特定HIV检测方法的意愿相关的人口统计学、行为、心理社会和社会结构因素:自我检测、在诊所或其他医疗机构检测以及伴侣HIV检测与咨询(CHTC)。
如果个体出生时为男性;年龄在16至二十八九岁之间;自我认定为黑人、非裔美国人、加勒比黑人、非洲黑人或多族裔黑人;未知感染HIV;且报告在过去12个月内与男性或跨性别女性有插入式或接受式肛交,则有资格参加基于网络的调查。通过在纽约市及全国范围内一系列社交和性网络网站及应用程序上投放横幅广告,以及通过纽约市年轻黑人男男性行为者和跨性别女性参加的活动进行招募。使用逻辑回归和最佳子集模型以及逐步变量选择分析每种检测方法的检测意愿。
在169名参与者中,使用自我检测的意愿与在家中由朋友或伴侣进行检测时的舒适度呈正相关(调整后的优势比,AOR,2.40;95%置信区间1.09 - 5.30),以及与作为不检测原因的耻辱感或恐惧呈正相关(AOR 8.61;95%置信区间),与较高的社会支持呈负相关(AOR 0.48;95%置信区间0.33 - 0.72),与拥有医疗保险呈负相关(AOR 0.21;95%置信区间0.09 - 0.54)。在诊所或其他医疗机构检测的意愿与HIV检测的自我效能感呈正相关(AOR 2.87;95%置信区间1.48 - 5.59)和社会支持呈正相关(AOR 1.98;95%置信区间1.34 - 2.92),与有监禁史呈负相关(AOR 0.37;95%置信区间0.16)。通过CHTC检测的意愿与较高的教育水平呈负相关(大专或副学士学位与高中或以下学历相比[AOR 0.81;95%置信区间0.39 - 1.70];学士学位或以上与高中或以下学历相比[AOR 0.28;95%置信区间0.11 - 0.70])。
独特因素与使用特定检测方法的检测意愿相关。这些数据对于开发一种有希望提高年轻黑人男男性行为者和跨性别女性对各种检测方法的舒适度和体验的个性化干预措施至关重要。
