Since 1984 a decrease in the prevalence of unprotected anogenital intercourse among homosexual men was observed in a longitudinal cohort study in Amsterdam. Two years ago, there was a strong indication that this trend was reversed, as the number of cases of gonorrhoea among homo- and bisexual visitors of the municipal STD clinic in Amsterdam started to increase again. In addition, recent analysis of behavioural data reported by participants in the cohort showed an increase in the percentage of men who had unprotected insertive or receptive anogenital intercourse (p < 0.05). Between the second half of 1990 and the second half of 1991, the percentage of men reporting unprotected insertive or receptive anogenital contact with a steady partner remained constant: 24.6% versus 27.7%. However, a serious increase occurred in the percentage of men having unprotected anogenital intercourse with casual partners (an increase from 13.1% to 24.0%; p < 0.01). Findings regarding the age distribution among homo- and bisexual men diagnosed with gonorrhoea indicate that the increase in unprotected anogenital contact was strongest among men under the age of thirty.
自1984年起，在阿姆斯特丹的一项纵向队列研究中观察到同性恋男性中无保护肛交性行为的发生率有所下降。两年前，有强烈迹象表明这一趋势出现逆转，因为阿姆斯特丹市性传播疾病诊所的同性恋和双性恋就诊者中淋病病例数再次开始增加。此外，对该队列参与者报告的行为数据的近期分析显示，进行无保护插入式或接受式肛交的男性比例有所增加（p < 0.05）。在1990年下半年至1991年下半年期间，报告与固定伴侣进行无保护插入式或接受式肛交接触的男性比例保持不变：分别为24.6%和27.7%。然而，与临时伴侣进行无保护肛交的男性比例出现了严重增加（从13.1%增至24.0%；p < 0.01）。关于被诊断患有淋病的同性恋和双性恋男性的年龄分布的研究结果表明，无保护肛交接触的增加在30岁以下男性中最为明显。
