The research topic of barebacking emerged in the mid-1990s. Since then, a multitude of studies, largely from the United States, have produced invaluable knowledge of factors that help explain the behaviour among men who have sex with men (MSM), and that may contribute to HIV risk reduction programming and advice to counsellors working with barebackers. Given the scant empirical research about barebacking among European MSM, we conducted a survey among 3,634 MSM recruited through a web community in Nordic countries. The objectives of the study were twofold: to describe the sexual activities associated with barebacking behaviour at last sexual encounter, and to evaluate the relationship of barebacking with relevant variables. Men who reported barebacking (n=356) and men who did not (n=3,278) were compared. On the basis of the results of the analyses, the socio-sexual profile of barebackers drawn was one that is at increased risk of acquiring human immunodeficiency virus (HIV) and other sexually transmitted infections due to their sexual practices, particularly unprotected anal intercourse, but also group sex and rimming. In a multivariate logistic regression analysis, the likelihood of engaging in barebacking was higher for MSM who reported more frequent HIV testing (odds ratio (OR)=5.16), a higher number of female sex partners (OR=16.80), using gay cruising places (OR=1.51) and gay chat rooms (OR=2.11).
“无保护肛交”（Barebacking）这一研究主题出现在 20 世纪 90 年代中期。从那时起，大量来自美国的研究产生了宝贵的知识，这些知识有助于解释男男性行为者（MSM）的行为，并且可能有助于制定 HIV 风险降低规划和为与“无保护肛交”者合作的顾问提供建议。鉴于欧洲 MSM 中关于“无保护肛交”的经验研究很少，我们在北欧国家的一个网络社区中招募了 3634 名 MSM 进行了一项调查。该研究的目的有两个：描述与上次性接触时“无保护肛交”行为相关的性活动，并评估“无保护肛交”与相关变量的关系。报告有“无保护肛交”行为的男性（n=356）和没有“无保护肛交”行为的男性（n=3278）进行了比较。基于分析结果，“无保护肛交”者的社会性行为特征是由于其性行为而处于感染人类免疫缺陷病毒（HIV）和其他性传播感染的风险增加，特别是无保护的肛交，还有群交和舔肛。在多变量逻辑回归分析中，报告更频繁的 HIV 检测（比值比（OR）=5.16）、更多的女性性伴侣（OR=16.80）、使用同性恋 cruising 场所（OR=1.51）和同性恋聊天室（OR=2.11）的 MSM 更有可能进行“无保护肛交”。
