To determine the prevalence and factors of Viagra use in combination with crystal methamphetamine and its association with HIV risk behavior in a probability sample of men who have sex with men (MSM).
A cross-sectional, random-digit dial telephone survey of MSM in San Francisco conducted between June 2002 and January 2003.
Of the 1976 MSM, 13.5% used Viagra alone, 7.1% used methamphetamine without Viagra, 9.6% used Viagra with a mood-altering substance (excluding methamphetamine), and 5.1% used Viagra with methamphetamine. Of the MSM using Viagra with methamphetamine, 57% were HIV-infected and 24% of these men reported serodiscordant unprotected insertive intercourse. Viagra used with methamphetamine was independently associated with a higher risk of serodiscordant unprotected insertive intercourse, serodiscordant unprotected receptive intercourse, and a recent diagnosis of a sexually transmitted disease.
MSM who use Viagra with crystal methamphetamine have high prevalence rates of HIV and engage in HIV risk behaviors.
在一个男男性行为者（MSM）概率样本中，确定同时使用伟哥与冰毒的流行情况及相关因素，以及其与HIV风险行为的关联。
2002年6月至2003年1月间，对旧金山的男男性行为者进行的一项横断面随机数字拨号电话调查。
在1976名男男性行为者中，13.5%仅使用伟哥，7.1%使用冰毒但不使用伟哥，9.6%使用伟哥并伴有改变情绪的物质（不包括冰毒），5.1%使用伟哥并使用冰毒。在同时使用伟哥和冰毒的男男性行为者中，57%感染了HIV，其中24%的男性报告有血清学不一致的无保护插入式性行为。同时使用伟哥和冰毒与血清学不一致的无保护插入式性行为、血清学不一致的无保护接受式性行为以及近期性传播疾病诊断的较高风险独立相关。
同时使用伟哥和冰毒的男男性行为者HIV感染率高且有HIV风险行为。
