The objective of this study was to investigate the relationship between sex work and HIV infection among young injection drug-using men who have sex with men (MSM-IDU).
This study was a cross-sectional analysis of behavioral and serologic data collected from 227 street-recruited MSM-IDU in San Francisco, California, between January 2000 and November 2001.
Sixty-eight percent of participants reported being paid by another man for sex. HIV prevalence was 12% (95% confidence interval, 8-16%); 42% of seropositive participants were unaware of their infection. HIV was independently associated with higher number of paying male partners and history of gonorrhea and inversely associated with number of female partners, education, and syringe-sharing. Consistent condom use overall was 41%, but varied significantly by type of partner.
Among MSM-IDU in San Francisco, sex work with men is strongly associated with HIV infection and the prevalence of condom use is low. HIV prevention among MSM-IDU must be tailored to address the excess risk associated with sex work.
本研究的目的是调查年轻的男男性行为注射吸毒者（MSM-IDU）中性工作与艾滋病毒感染之间的关系。
本研究是对2000年1月至2001年11月期间在加利福尼亚州旧金山街头招募的227名MSM-IDU收集的行为和血清学数据进行的横断面分析。
68%的参与者报告曾因性行为而从另一名男性那里获得报酬。艾滋病毒感染率为12%（95%置信区间，8%-16%）；42%的血清学阳性参与者不知道自己已感染。艾滋病毒与付费男性性伴侣数量较多以及淋病病史独立相关，与女性性伴侣数量、受教育程度和共用注射器呈负相关。总体而言，始终坚持使用避孕套的比例为41%，但因性伴侣类型不同而有显著差异。
在旧金山的MSM-IDU中，与男性的性工作与艾滋病毒感染密切相关，避孕套使用率较低。对MSM-IDU的艾滋病毒预防必须针对与性工作相关的额外风险进行调整。
