To describe the pattern of drug use among men who have sex with men (MSM) living in Spain and its association with sexual risk practices.
The European MSM Internet Survey was implemented in 2010 in 38 European countries on websites for MSM and collected data on sociodemographics, sexual behavior, and other sexual health variables. The association between unprotected anal intercourse (UAI) with casual partners and drug consumption was evaluated using multivariate logistic regression models.
Among the 13,111 participants, most consumed drugs were cannabis (30.1%), popper (28.4%) and cocaine (18.7%). The risk of UAI with casual partners was 1.5 among those who had used drugs in relation to the other participants. The proportion of MSM who had injected drugs at least once in life was 2.5%, and 1.4% in the last 12 months. The prevalence of UAI with casual partners (53.4%), human immunodeficiency virus (HIV) (23%), hepatitis C (8.2%) and sexually transmitted infections (STI) (15.8%) was higher in MSM injectors related to those who had not used injected drugs (P<.05).
The results of this study confirm a high prevalence of drug use in MSM and their relationship to sexual risk behavior. Although the use of injected drugs in MSM is a minority, this group reported a higher level of sexual risk behaviors, self-reported HIV, hepatitis C and other STI.
描述居住在西班牙的男男性行为者（MSM）的药物使用模式及其与性风险行为的关联。
2010年在38个欧洲国家的男男性行为者网站上开展了欧洲男男性行为者互联网调查，收集了社会人口统计学、性行为及其他性健康变量的数据。使用多因素逻辑回归模型评估与偶然伴侣发生无保护肛交（UAI）与药物消费之间的关联。
在13111名参与者中，使用最多的药物是大麻（30.1%）、Poppers（28.4%）和可卡因（18.7%）。与其他参与者相比，使用过药物的人发生UAI的风险是1.5。一生中至少注射过一次药物的男男性行为者比例为2.5%，在过去12个月中为1.4%。与未使用过注射药物的男男性行为者相比，注射药物的男男性行为者中与偶然伴侣发生UAI（53.4%）、感染人类免疫缺陷病毒（HIV）（23%）、丙型肝炎（8.2%）和性传播感染（STI）（15.8%）的患病率更高（P<0.05）。
本研究结果证实男男性行为者中药物使用率较高及其与性风险行为的关系。虽然男男性行为者中注射药物的使用是少数情况，但该群体报告的性风险行为、自我报告的HIV、丙型肝炎和其他性传播感染水平较高。
