背景：尽管在白人男同性恋者中使用兴奋剂与性冒险和艾滋病毒传播之间的关联已得到充分记录，但在男男性行为黑人 (MSM) 中，性行为期间使用兴奋剂的情况仍未得到充分研究。方法：2008 年 1 月至 7 月期间通过改良的受访者驱动抽样招募的黑人 MSM (n=197) 完成了由访谈员管理的定量评估和可选的艾滋病毒咨询和检测。采用双变量逻辑回归程序来检查人口统计、性风险和其他心理社会因素与兴奋剂使用的关联（在过去 12 个月的性行为期间至少每月一次）。使用向后选择过程进行变量消除，用于拟合两个独立的最终多变量逻辑回归模型，检查兴奋剂使用作为结果，以及过去 12 个月内按性别划分的 HIV 性风险作为主要预测因子：(1) 模型 1：以临时男性性伴侣作为主要强制预测因子的 HIV 性风险行为； (2) 模型 2：以女性性伴侣为主要强制预测因子的 HIV 性风险行为。结果：三分之一 (34%) 的黑人 MSM 报告称，在过去 12 个月中，每月或更频繁地在性行为中使用兴奋剂。以下因素与性行为中兴奋剂的使用独立相关：（1）模型 I：过去 12 个月内与临时男性性伴侣进行无保护肛交（AOR = 2.61；95% CI = 1.06-6.42；p = 0.01）、年龄较大（AOR = 1.09；95% CI = 1.05-1.15；p
Background: Although the association of stimulant use to sexual risk taking and HIV transmission has been well documented among white gay men, stimulant use during sex continues to be under-explored among Black men who have sex with men (MSM).Methods: Black MSM (n=197) recruited via modified respondent-driven sampling between January and July 2008 completed an interviewer-administered quantitative assessment and optional HIV counseling and testing. Bivariate logistic regression procedures were employed to examine the association of demographics, sexual risk, and other psychosocial factors with stimulant use (at least monthly during sex in the past 12 months). Variable elimination using the backward selection process was used to fit two separate final multivariable logistic regression models examining stimulant use as the outcome and HIV sexual risk in the past 12 months by gender as the primary predictor: (1) Model 1: HIV sexual risk behavior with a casual male sex partner as a primary, forced predictor; (2) Model 2: HIV sexual risk behavior with a female sex partner as primary, forced predictor.Results: One-third (34%) of Black MSM reported using stimulants monthly or more frequently during sex in the past 12 months. The following factors were independently associated with stimulant use during sex: (1) Model I: unprotected anal sex with a casual male sex partner in the past 12 months (AOR =2.61; 95% CI = 1.06-6.42; p = 0.01), older age (AOR= 1.09; 95% CI =1.05-1.15; p
