目的：为了评估艾滋病预防干预措施的影响与社交网络的年轻男子与男性发生性关系（YMSM）在彼得堡，俄罗斯和索菲亚，Bulgaria.Design：一个双臂随机试验与一个selfally-followed community coherent.Methods：52 MSM社交网络被招募通过接入点在高风险的社区场地。网络成员（n = 276）进行了评估，以确定风险特征，管理的社会计量措施，以经验确定每个网络的社会领导人，并在风险降低咨询。25个实验条件网络的领导人参加了一个九次会议的方案，该方案提供培训和指导，向其他网络成员提供持续的基于理论的艾滋病毒预防建议。领导先后针对网络成员的艾滋病风险相关知识和降低风险的规范、态度、意愿、自我效能感等进行了调查。参与者在3个月和12个月的follows.Results重新管理的风险评估措施：在产生的变化，实验网络成员报告无保护性交（UI）的百分比下降到48.4%，在3个月的随访（P = 0.0001）。与多个伴侣进行UI的比例从31.5%下降到12.9%（P = 0.02）。12个月后，这种影响减弱，但在最近有多个性伴侣的参与者中仍然存在，这是最脆弱的群体。控制组networks.Conclusions：干预措施，从事确定的影响力领导人的风险YMSM社交网络沟通理论为基础的咨询和建议，可以产生显着的性风险行为的变化。这一模式在文化上与前社会主义国家的艾滋病毒预防工作相关，也与其他地方难以接触到的脆弱社区人口相关。(c)2005年利平科特威廉姆斯&威尔金斯。
Objective: To evaluate the effects of an HIV prevention intervention with social networks of young men who have sex with men (YMSM) in St. Petersburg, Russia and Sofia, Bulgaria.Design: A two-arm randomized trial with a longitudinally-followed community cohort.Methods: Fifty-two MSM social networks were recruited through access points in high-risk community venues. Network members (n = 276) were assessed to determine risk characteristics, administered sociometric measures to empirically identify the social leader of each network, and counseled in risk reduction. The leaders of 25 experimental condition networks attended a nine-session program that provided training and guidance in delivering ongoing theory-based HIV prevention advice to other network members. Leaders successively targeted network members' AIDS risk-related knowledge and risk reduction norms, attitudes, intentions, and self-efficacy. Participants were re-administered risk assessment measures at 3- and 12-month follow-ups.Results: Among changes produced, the percentage of experimental network members reporting unprotected intercourse (UI) declined from 71.8 to 48.4% at 3-month follow up (P = 0.0001). The percentage who engaged in UI with multiple partners reduced from 31.5 to 12.9% (P = 0.02). After 12 months, the effects became attenuated but remained among participants who had multiple recent sexual partners, the most vulnerable group. Little change was found in control group networks.Conclusions: Interventions that engage the identified influence leaders of at-risk YMSM social networks to communicate theory-based counseling and advice can produce significant sexual risk behavior change. This model is culturally pertinent for HIV prevention efforts in former socialist countries, as well as elsewhere for other hard-to-reach vulnerable community populations.
