INTRODUCTION: The use of combination HIV prevention interventions (CHPI) now represent the standard of care to minimize HIV acquisition risks among men who have sex with men (MSM). There has been limited evaluation of these approaches in generalized HIV epidemics and/or where MSM are stigmatized. A peer-based CHPI program to target individual, social, and structural risks for HIV was developed for MSM in Blantyre, Malawi. METHODS: To test the feasibility of CHPI, adult MSM were followed prospectively from January 2012 to May 2013. Participants (N = 103) completed sociobehavioral surveys and HIV testing at each of the 3 follow-up study visits. RESULTS: Approximately 90% of participants attended each study visit and 93.2% (n = 96) completed the final visit. Participants met with peer educators a median of 3 times (range: 1-10) in the follow-up visits 2 and 3. Condom use at last sex improved from baseline through follow-up visit 3 with main (baseline: 62.5%, follow-up 3: 77.0%; P = 0.02) and casual male partners (baseline: 70.7%, follow-up 3: 86.3%; P = 0.01). Disclosure of sexual behaviors/orientation to family increased from 25% in follow-up 1 to 55% in follow-up 3 (P < 0.01). DISCUSSION: Participants maintained a high level of retention in the study highlighting the feasibility of leveraging community-based organizations to recruit and retain MSM in HIV prevention and treatment interventions in stigmatizing settings. Group-level changes in sexual behavior and disclosure in safe settings for MSM were noted. CHPI may represent a useful model to providing access to other HIV prevention for MSM and aiding retention in care and treatment services for MSM living with HIV in challenging environments.
引言:目前,联合使用艾滋病病毒预防干预措施(CHPI)是降低男男性行为者(MSM)感染艾滋病病毒风险的标准治疗方法。在艾滋病病毒广泛流行和/或男男性行为者受到污名化的地区,对这些方法的评估有限。在马拉维的布兰太尔,为男男性行为者制定了一项基于同伴的CHPI计划,以针对艾滋病病毒的个人、社会和结构风险。 方法:为测试CHPI的可行性,于2012年1月至2013年5月对成年男男性行为者进行前瞻性随访。参与者(N = 103)在3次随访研究中的每次访视时均完成社会行为调查和艾滋病病毒检测。 结果:约90%的参与者参加了每次研究访视,93.2%(n = 96)完成了最后一次访视。在随访第2次和第3次访视中,参与者与同伴教育者见面的中位数为3次(范围:1 - 10次)。从基线到随访第3次访视,与主要男性伴侣(基线:62.5%,随访3:77.0%;P = 0.02)和临时性男性伴侣(基线:70.7%,随访3:86.3%;P = 0.01)发生性行为时使用避孕套的情况有所改善。向家人披露性行为/性取向的比例从随访1时的25%增加到随访3时的55%(P < 0.01)。 讨论:参与者在研究中的保留率很高,这突出了利用社区组织在有污名化环境中招募和保留男男性行为者参与艾滋病病毒预防和治疗干预措施的可行性。注意到男男性行为者在安全环境中性行为和披露方面的群体层面变化。CHPI可能是一种有用的模式,可为男男性行为者提供其他艾滋病病毒预防措施,并帮助生活在具有挑战性环境中的感染艾滋病病毒的男男性行为者坚持接受护理和治疗服务。
