To investigate trends in homosexual men's sexual risk behaviour for HIV infection in Scotland.
Cross sectional surveys in 1996, 1999, and 2002 were carried out in "gay" bars in Glasgow and Edinburgh, Scotland. 6508 men-2276 (79% response rate) in 1996, 2498 (78%) in 1999, and 1734 (62%) in 2002.
In 1996, 10.7% of men surveyed and in 1999, 11.2% reported unprotected anal intercourse (UAI) with casual partners, compared with 18.6% in 2002 (p < 0.001). There was also a significant increase in men reporting that they "knew" their casual partners' HIV status, despite no increase in HIV testing among men who reported UAI with casual partners. In 2002, increases in UAI with more than one partner, in UAI with casual partners and in reporting seroconcordance remained significant after adjusting for confounding factors including HIV testing status and demographic characteristics.
High risk sexual behaviour among homosexual men in Scotland increased between 1999 and 2002. Men showed increased confidence of shared antibody status, despite no increase in HIV testing, or evidence of discussion of HIV status. Explanations for this must include consideration of a cultural shift in the perception of HIV and "prevention failure" on the part of governments and health agencies.
调查苏格兰男同性恋者感染艾滋病毒的性风险行为趋势。
于1996年、1999年和2002年在苏格兰格拉斯哥和爱丁堡的“同性恋”酒吧进行横断面调查。共有6508名男性参与，1996年有2276人（应答率79%），1999年有2498人（应答率78%），2002年有1734人（应答率62%）。
1996年，接受调查的男性中有10.7%，1999年有11.2%报告称与偶然伴侣发生过无保护肛交（UAI），而2002年这一比例为18.6%（p<0.001）。报告称“了解”其偶然伴侣艾滋病毒感染状况的男性人数也显著增加，尽管与偶然伴侣发生无保护肛交的男性中进行艾滋病毒检测的人数并未增加。在调整包括艾滋病毒检测状况和人口统计学特征等混杂因素后，2002年与多个伴侣发生无保护肛交、与偶然伴侣发生无保护肛交以及报告血清学一致的情况仍显著增加。
1999年至2002年间，苏格兰男同性恋者中的高风险性行为有所增加。尽管艾滋病毒检测没有增加，也没有关于艾滋病毒感染状况讨论的证据，但男性对共享抗体状况的信心有所增强。对此的解释必须包括考虑对艾滋病毒认知的文化转变以及政府和卫生机构方面的“预防失败”。
