目的：要研究的地理变化，艾滋病毒的流行（诊断和未诊断），使用性健康服务，性传播感染和性行为的男性发生性关系的男性在英格兰的三个城市，特别是伦敦，布莱顿和Manchester.Methods的社区样本中的男性访问同性恋社区场地在英格兰的三个大城市的横断面调查。结果：3个城市的HIV感染率在8.6%~ 13.7%之间。在所有地点，超过三分之一的艾滋病毒感染仍未得到诊断，尽管去年有69%的艾滋病毒阳性男子报告去过泌尿生殖医学诊所。所有三个城市都报告了类似的高风险行为。18%的艾滋病毒阴性男性和37%的艾滋病毒阳性男性报告在过去一年中与一个以上的伴侣进行了无保护的肛交。20%的阴性男性和41%的阳性男性在过去一年中报告了STI。结论：在所有城市，尽管广泛提供抗逆转录病毒治疗和国家政策，以促进艾滋病毒检测，许多艾滋病毒感染仍然未确诊。来自这一社区抽样的数据表明，风险行为和性传播感染发病率很高，特别是在艾滋病毒阳性者中。需要作出新的努力，增加诊断，减少危险行为，以阻止艾滋病毒的继续传播。
Objectives: To examine the geographical variations in HIV prevalence (diagnosed and undiagnosed), use of sexual health services, sexually transmitted infections and sexual behaviour in a community sample of men who have sex with men in three cities in England, specifically London, Brighton and Manchester.Methods: Cross-sectional surveys of men visiting gay community venues in three large cities in England. Men self-completed a questionnaire and provided an anonymous oral fluid sample for HIV antibody testing.Results: HIV prevalence ranged from 8.6% to 13.7% in the three cities. Over one-third of HIV infection remained undiagnosed in all sites despite 69% of HIV-positive men reporting attending a genitourinary medicine clinic in the last year. Similar and high levels of risk behaviour were reported in all three cities. 18% of HIV-negative men and 37% of HIV-positive men reported unprotected anal intercourse with more than one partner in the last year. 20% of negative men and 41% of positive men reported an STI in the last year.Conclusions: Across all cities, despite widespread availability of anti-retroviral treatment and national policy to promote HIV testing, many HIV infections remain undiagnosed. Data from this community sample demonstrate high levels of risk behaviour and STI incidence, especially among those who are HIV positive. Renewed efforts are needed to increase diagnosis and to reduce risk behaviour to stem the continuing transmission of HIV.
