We assessed the efficacy of an HIV behavioral intervention adapted for Black men who have sex with men (MSM).
We conducted serial cross-sectional surveys, 1 baseline measurement followed by initiation of an intervention and 3 follow-up measurements, among Black MSM in 3 North Carolina cities over 1 year.
We observed significant decreases in unprotected receptive anal intercourse at 4 months (by 23.8%, n=287) and 8 months (by 24.7%, n=299), and in unprotected insertive anal intercourse (by 35.2%), unprotected receptive anal intercourse (by 44.1%), and any unprotected anal intercourse (by 31.8%) at 12 months (n=268). Additionally, at 12 months, the mean number of partners for unprotected receptive anal intercourse decreased by 40.5%. The mean number of episodes decreased by 53.0% for unprotected insertive anal intercourse, and by 56.8% for unprotected receptive anal intercourse. The percentage of respondents reporting always using condoms for insertive and receptive anal intercourse increased by 23.0% and 30.3%, respectively.
Adapting previously proven interventions designed for other MSM can significantly reduce HIV risk behaviors of Black MSM.
我们评估了一种针对与男性发生性关系的黑人男性（男男性行为者）量身定制的艾滋病病毒行为干预措施的效果。
我们在北卡罗来纳州的3个城市，对男男性行为者进行了为期1年的系列横断面调查，包括1次基线测量，随后启动干预措施，并进行3次随访测量。
我们观察到，在4个月时（下降23.8%，n = 287）和8个月时（下降24.7%，n = 299），无保护的被动肛交显著减少；在12个月时（n = 268），无保护的主动肛交（下降35.2%）、无保护的被动肛交（下降44.1%）以及任何无保护的肛交行为（下降31.8%）均显著减少。此外，在12个月时，无保护被动肛交的性伴侣平均数量减少了40.5%。无保护主动肛交的性行为次数平均减少了53.0%，无保护被动肛交的性行为次数平均减少了56.8%。报告在主动和被动肛交时始终使用避孕套的受访者比例分别增加了23.0%和30.3%。
调整先前为其他男男性行为者设计的已证实有效的干预措施，可显著降低黑人男男性行为者的艾滋病病毒风险行为。
