BACKGROUND
Substance use has been associated with high-risk sexual behavior among men who have sex with men (MSM) both in the U.S. and around the world. Recent efforts by local organizations in San Francisco have specifically targeted methamphetamine use in this population.
METHODS
We tracked methamphetamine and other substance use among men who have sex with men (MSM) in San Francisco from 2003 to 2006 using an indicator available in community outreach surveys of a prevention education program targeting MSM (n=4602).
RESULTS
Overall, use of diverse substances tended to decrease from 2003 to 2006, many significantly so. Reported use of methamphetamine significantly decreased among HIV-negative MSM. However, methamphetamine and alcohol use during sex was associated with unprotected potentially HIV serodiscordant sex.
CONCLUSION
Intensified prevention efforts to reduce methamphetamine use in San Francisco may be having some impact; however, strong associations of substance use and high-risk sex persist.
背景
在美国及全球范围内，物质使用与男男性行为者（MSM）的高风险性行为相关。旧金山当地组织近期的工作特别针对该人群中的甲基苯丙胺使用情况。
方法
我们利用针对男男性行为者的预防教育项目社区外展调查中可用的一项指标，追踪了2003年至2006年旧金山男男性行为者中的甲基苯丙胺及其他物质使用情况（n = 4602）。
结果
总体而言，从2003年到2006年，多种物质的使用呈下降趋势，其中许多物质的下降幅度显著。在HIV阴性的男男性行为者中，甲基苯丙胺的报告使用量显著下降。然而，性行为期间使用甲基苯丙胺和酒精与无保护的潜在HIV血清学不一致性行为有关。
结论
旧金山加强减少甲基苯丙胺使用的预防工作可能正在产生一些影响；然而，物质使用与高风险性行为之间的紧密关联依然存在。
