目的：研究艾滋病毒乐观主义（即根据新的艾滋病毒药物治疗的乐观主义）是否可以解释最近伦敦男同性恋者中高危性行为的增加。方法：1998年至2001年间，每年对2938名在伦敦健身的男同性恋者进行调查。收集了有关艾滋病毒状况、前3个月无保护肛交（UAI）的信息，并与关于艾滋病毒感染严重程度和易感性的两项声明达成一致。同意的人被归为“乐观”。结果：1998年至2001年间，报告高危性尿路感染（即与艾滋病毒感染状况不明或不一致的偶然性伴侣发生尿路感染）的男性比例增加：艾滋病毒阳性男性15.3-38.8%；hiv阴性男性6.8-12.1%；未检测男性2.1-7.7%；（p < 0.01）。总体而言，不到三分之一的人持乐观态度。在横断面分析中，乐观的hiv阳性和阴性男性报告高危UAI的可能性高于其他男性（P < 0.05）。然而，在1998年至2001年期间，乐观和不乐观的人群中高危UAI的增加（P < 0.05）。在多变量分析中，在控制HIV乐观情绪后，高危UAI模型随时间的增加仍然显著（P < 0.01），乐观情绪与时间之间无显著交互作用。结论：从1998年到2001年，在伦敦的男同性恋者中，乐观的人和不乐观的人在高危性行为的增加率方面没有发现差异。我们的研究结果表明，HIV乐观主义不太可能解释最近这些男性高危性行为的增加。(C) 2002利平科特·威廉姆斯·威尔金斯。
Objective: To examine whether HIV optimism (i.e. optimism in the light of new HIV drug therapies) can account for the recent increase in high-risk sexual behaviour among London gay men.Methods: Gay men (n = 2938) using London gyms were surveyed annually between 1998 and 2001. Information was collected on HIV status, unprotected anal intercourse (UAI) in the previous 3 months, and agreement with two statements concerning the severity of and susceptibility to HIV infection. Those who agreed were classified as 'optimistic'.Results: Between 1998 and 2001, the percentage of men reporting high-risk UAI (i.e. UAI with a casual partner of unknown or discordant HIV status) increased: HIV-positive men 15.3-38.8%; HIV-negative men 6.8-12.1%; never-tested men 2.1-7.7%; (P < 0.01). Overall, less than a third were optimistic. In cross-sectional analysis, optimistic HIV-positive and -negative men were more likely to report high-risk UAI than other men (P < 0.05). However, the increase in high-risk UAI between 1998 and 2001 was seen in those who were optimistic and those who were not (P < 0.05). In multivariate analysis, the modelled increase in high-risk UAI over time remained significant after controlling for HIV optimism (P < 0.01), with no significant interaction between optimism and time.Conclusion: Among London gay men, no difference was detected between those who were optimistic and those who were not in the rate of increase in high-risk sexual behaviour between 1998 and 2001. Our findings suggest that HIV optimism is unlikely to explain the recent increase in high-risk sexual behaviour in these men. (C) 2002 Lippincott Williams Wilkins.
