African American men who have sex with men and women (MSMW) are among the populations with the highest need for HIV prevention programs in the USA. We tested a theory-based, community participatory behavioral intervention aiming to reduce sexual risk for HIV transmission in this population. A randomized clinical trial involving 396 African American MSMW who were assigned to a 4-session intervention involving HIV testing and counseling (n = 199) or to a HIV testing and counseling only (n = 197) control. In the 4-session intervention program, counselors provided education on HIV and STI risk, condom use, HIV testing, interpersonal sexual dynamics with both male and female partners, and motivational "triggers" of condomless sex. Participants completed baseline, 6-month, and 9-month assessments, and changes in HIV behavioral risk indicators were examined by condition and time. There were no statistically significant differences in sexual risk between the intervention condition and the control condition. Regardless of condition, participants reported significant reductions in mean number of condomless sex events with female casual partners from baseline (6.04) to 6 months (2.58) and 9 months (1.47), and with male casual partners from baseline (2.61) to 6 months (1.18) and 9 months (0.60). Condition-by-time interaction effects and condition main effects were non-significant. Although there were no significant differences by condition, findings support the effects of brief behavioral counseling and HIV testing on reducing condomless sex with casual female and male partners among African American MSMW. Future research should examine further the potential for brief behavioral counseling to promote biomedical HIV prevention and to reduce co-morbid health issues such as substance use among African American MSMW.
美国的艾滋病预防项目中,性活跃的非裔美国男男性行为者和异性恋女性(MSMW)是高危人群之一。我们对一个以理论为基础,社区参与的行为干预项目进行了测试,旨在降低该人群中的艾滋病病毒传播风险。这是一个随机临床试验,涉及 396 名非裔美国 MSMW,他们被分配到包括 HIV 检测和咨询的 4 次干预组(n = 199)或仅 HIV 检测和咨询的对照组(n = 197)。在 4 次干预项目中,咨询师提供了有关艾滋病和性传播感染风险、 condom 使用、HIV 检测、与男性和女性伴侣的人际性动态以及 condomless sex 的动机“触发因素”的教育。参与者完成了基线、6 个月和 9 个月的评估,并根据条件和时间检查了 HIV 行为风险指标的变化。干预组和对照组之间的性风险没有统计学上的显著差异。无论条件如何,参与者报告说,与女性偶然伴侣的 condomless sex 事件的平均数量从基线(6.04)减少到 6 个月(2.58)和 9 个月(1.47),与男性偶然伴侣的 condomless sex 事件的平均数量从基线(2.61)减少到 6 个月(1.18)和 9 个月(0.60)。条件-时间交互作用和条件主要作用不显著。尽管两组之间没有显著差异,但研究结果支持简短的行为咨询和 HIV 检测在减少非裔美国 MSMW 与偶然的女性和男性伴侣之间 condomless sex 的效果。未来的研究应进一步探讨简短的行为咨询在促进非洲裔美国 MSMW 的生物医学艾滋病预防和减少共病健康问题(如药物使用)方面的潜力。
