Using respondent-driven sampling (RDS), an integrated biological behavioral survey among men that have sex with men (MSM) enrolled 457 participants in Maputo [63.0 % were MSM who had sex with women (MSMW)], 538 in Beira (36.2 % MSMW) and 330 in Nampula-Nacala (54.8 % MSMW) in 2011. Analysis suggests that MSM who have sex only with men (MSMO) had increased odds of having HIV (aOR 2.7) compared to MSMW. HIV among MSMO associated with age, self-reported STI (aOR 4.2), having a single male anal partner (aOR 3.8) and having transactional sex with a man (aOR 3.5) in the past year. Among MSMW, HIV associated with age, lower education (aOR 32.5), being uncircumcised (aOR 3.1) and having transactional sex with a woman (aOR 6.0) in the past year. Findings confirm that MSMO and MSMW have distinct HIV risks in Mozambique; HIV programs for MSM in Southern Africa should take such differences into consideration.
2011年,通过应答驱动抽样(RDS)方法,在马普托、贝拉和楠普拉-纳卡拉对男男性行为者(MSM)开展了一项综合生物行为调查,分别有457名、538名和330名参与者入组(马普托63.0%为与女性发生性行为的男男性行为者[MSMW],贝拉为36.2%,楠普拉-纳卡拉为54.8%)。分析表明,与MSMW相比,仅与男性发生性行为的男男性行为者(MSMO)感染艾滋病毒的几率增加(调整后比值比[aOR]为2.7)。在MSMO中,艾滋病毒感染与年龄、自我报告的性传播感染(aOR为4.2)、有单一男性肛交性伴侣(aOR为3.8)以及在过去一年与男性发生交易性行为(aOR为3.5)有关。在MSMW中,艾滋病毒感染与年龄、受教育程度较低(aOR为32.5)、未行包皮环切术(aOR为3.1)以及在过去一年与女性发生交易性行为(aOR为6.0)有关。研究结果证实,在莫桑比克,MSMO和MSMW面临不同的艾滋病毒感染风险;南部非洲针对男男性行为者的艾滋病毒防治项目应考虑到这些差异。
