Injection drug-using men from the US and Mexico who purchase sex in Tijuana, Mexico are at risk for transmitting HIV to their contacts in both countries via syringe sharing. We used social network methods to understand whether place of residence (US vs. Mexico) moderated the effect of emotional closeness on syringe sharing. We interviewed 199 drug-using men who reported paying/trading for sex in Tijuana, Mexico using an epidemiological and social network survey and collected samples for HIV/STI testing. Seventy-two men reported using injection drugs with 272 network contacts. Emotional closeness was strongly associated with syringe sharing in relationship where the partner lives in the US, while the relationship between emotional closeness and syringe sharing was considerably less strong in dyads where the partner lives in Mexico. Efforts to reduce HIV risk behaviors in emotionally close relationships are needed, and could benefit from tailoring to the environmental context of the relationship.
在美国和墨西哥，在墨西哥蒂华纳购买性服务的注射吸毒男性有通过共用注射器将艾滋病毒传播给两国性伴侣的风险。我们运用社交网络方法来了解居住地（美国与墨西哥）是否会调节情感亲密度对共用注射器行为的影响。我们采用流行病学和社交网络调查，对199名报告在墨西哥蒂华纳购买性服务或进行性交易的吸毒男性进行了访谈，并采集样本进行艾滋病毒/性传播感染检测。72名男性报告称与272名社交网络联系人共用过注射毒品。在性伴侣居住在美国的关系中，情感亲密度与共用注射器行为密切相关，而在性伴侣居住在墨西哥的二元关系中，情感亲密度与共用注射器行为之间的关联则弱得多。需要努力减少情感亲密关系中的艾滋病毒风险行为，并且根据关系的环境背景进行调整可能会有所助益。
