This study aims to characterize the profile of male injecting drug users who have sex with other men (MSM IDUs) recruited through a cross-sectional multi-city survey (AjUDE-Brasil II Project) in six Brazilian cities, in 2000-2001. MSM IDUs were compared to other male IDUs using bivariate and multivariate procedures (logistic regression and answer tree analysis with the CHAID algorithm). Among the 709 male IDUs, 187 (26.4%) reported ever having had sex with other men, while only 37 reported sex with other men in the previous six months. MSM IDUs were more likely to be unemployed (OR = 2.3), to have injected tranquilizers (OR = 3.6), and to be HIV-seropositive (OR = 2.1), compared to other male IDUs. Male same-sex relations in this subgroup appear to be associated with strategies to finance drug consuming habits, including sex for drugs with occasional female partners or obtaining injection paraphernalia from occasional sex partners. Further studies should focus on this especially vulnerable subgroup of IDUs, due to the bidirectional and complex interrelationships between their drug injecting habits and sexual risk behaviors.
本研究旨在描述2000 - 2001年通过巴西六个城市的横断面多城市调查（阿朱德 - 巴西二号项目）招募的男男性行为注射吸毒者（MSM IDUs）的特征。采用双变量和多变量方法（逻辑回归以及使用CHAID算法的决策树分析），将男男性行为注射吸毒者与其他男性注射吸毒者进行比较。在709名男性注射吸毒者中，187人（26.4%）报告曾与其他男性发生过性行为，而在前六个月中只有37人报告与其他男性发生过性行为。与其他男性注射吸毒者相比，男男性行为注射吸毒者更有可能失业（比值比 = 2.3）、注射过镇静剂（比值比 = 3.6）且艾滋病毒血清呈阳性（比值比 = 2.1）。该亚组中的男性同性关系似乎与为吸毒习惯筹集资金的策略有关，包括与偶尔的女性性伴进行以性换毒品或从偶尔的性伴处获取注射用具。由于该注射吸毒者亚组特别脆弱，其吸毒习惯与性风险行为之间存在双向且复杂的相互关系，因此进一步的研究应聚焦于此。
