目的：估计英国男性同性恋经历的流行和时间;探讨2000年的性行为和伙伴关系模式，以及1990年至2000年期间与男性发生性关系的男性（MSM）的行为和态度变化。设计：两个大型分层概率抽样调查的一般人群。方法：受过训练的采访者对居住在英国的16至44岁的男性进行了面对面和自我完成的问卷调查（1990年n = 6000，2000年n = 4762）。结果：2000年，2.8%的英国男性报告在过去5年内与男性发生过性行为。46.0%的MSM在过去5年内有5名以上性伴，59.8%的MSM在过去1年内有过无保护肛交。33.0%的男男性行为者报告在过去一年中有一个或多个女性伴侣。与1990年相比，2000年男男性接触者在总人口中的比例有显著性增加，其中在过去一年中报告接受肛交的比例[年龄调整比值比（OR），2.08; 95%置信区间（CI），1.08-4.00]，但自我感知的艾滋病毒风险无显著变化（年龄调整OR，1.11; 95% CI，0.49-2.51）或过去5年内进行过HIV检测（年龄校正OR，1.14; 95%CI，0.57-2.25）。有证据表明，英国男性人口中同性性行为的流行率越来越高，同时一些艾滋病毒感染者的数量也在增加，男男性行为者的风险行为表明，人口中处于风险中的人数总体上在增加。虽然这些变化可能部分反映了报告这些行为的意愿增加，但我们的结果与性传播感染发病率和行为监测数据的增加是一致的。(C)2004年利平科特威廉姆斯威尔金斯。
Objectives: To estimate the prevalence and timing of homosexual experience among British men; to explore the patterns of sexual practices and partnerships in 2000, and behavioural and attitudinal changes between 1990 and 2000 among men who have sex with men (MSM).Design: Two large, stratified probability sample surveys of the general population.Methods: Trained interviewers administered a combination of face-to-face and self-completion questionnaires to men aged 16 to 44 years resident in Britain (n = 6000 in 1990 and n = 4762 in 2000).Results: in 2000, 2.8% of British men reported sex with men in the past 5 years. 46.0% of MSM reported five or more partners in the past 5 years, and 59.8% reported unprotected anal intercourse in the past year. A total of 33.0% of MSM reported one or more female partner(s) in the past year. In comparison with 1990, there was a significant increase in the proportion of MSM in the population in 2000, and among these men, in the proportion reporting receptive anal intercourse in the past year [age-adjusted odds ratio (OR), 2.08; 95% confidence interval (CI), 1.08-4.00], but no significant change in self-perceived HIV-risk (age-adjusted OR, 1.11; 95% Cl, 0.49-2.51) or HIV testing in past 5 years (age-adjusted OR, 1.14; 95% Cl, 0.57-2.25).Conclusions: Evidence of increasing prevalence of homosexual intercourse among the British male population coupled with increases in some HIV-risk behaviours among MSM suggests overall increasing numbers at risk in the population. Although these changes may partly reflect an increased willingness to report these behaviours, our results are consistent with increasing incidence of sexually transmitted infections and behavioural surveillance data.
