Although the association of partnership concurrency and HIV prevalence has been studied in sub-Saharan settings, the impact of concurrency on HIV transmission has not. We investigated the association between concurrency and HIV serodiscordance in 142 ongoing marital and nonmarital relationships in which both partners were traced and tested for HIV. Our results suggest that multiple concurrent partnerships significantly increase exposure to HIV infection in the population of Likoma (Malawi). We highlight the potential role of behavioral interventions addressing partnership concurrency for HIV prevention.
尽管在撒哈拉以南地区已经研究了伴侣同时存在的情况与 HIV 流行率之间的关联，但尚未研究同时存在对 HIV 传播的影响。我们调查了追踪和测试 HIV 的 142 个正在进行的婚姻和非婚姻关系中同时存在的情况与 HIV 血清不一致之间的关联。我们的研究结果表明，在 Likoma（马拉维）人群中，多重同时存在的伴侣关系会大大增加感染 HIV 的风险。我们强调了针对伴侣同时存在情况的行为干预措施在 HIV 预防方面的潜在作用。
