The surveillance of HIV prevalence and incidence and of sexual risk behaviour among young homosexual men.
Cohort study, cross-sectional data presentation.
Municipal Health Service of the City of Amsterdam, the Netherlands.
At entry into the study participants were questioned about their sexual behaviour and blood or saliva samples were collected for laboratory determination of antibodies against HIV, hepatitis B and syphilis.
In June 1995-October 1996, 429 men with a mean age of 25 years were enrolled in the cohort study. Of these 22 (5%) were positive for antibodies against HIV. Based on the duration of homosexual activity of the participants the HIV incidence in this group was estimated at 1% per year. Furthermore, 10% of the participants had experienced hepatitis B infection and 1% had serological evidence of syphilis. Of those under investigation 38% had practised unprotected anogenital intercourse with steady or non-steady partners in the last six months.
The data suggest that HIV is spreading among young homosexual men. Given the high levels of risk behaviour continued prevention activities in this group are necessary.
监测年轻男同性恋者中艾滋病毒的流行率、发病率及性行为风险。
队列研究，横断面数据呈现。
荷兰阿姆斯特丹市市政卫生服务机构。
研究开始时，对参与者进行性行为询问，并采集血液或唾液样本，用于实验室检测艾滋病毒、乙型肝炎和梅毒抗体。
1995年6月至1996年10月，429名平均年龄25岁的男性被纳入队列研究。其中22人（5%）艾滋病毒抗体呈阳性。根据参与者同性恋活动的持续时间，该组艾滋病毒发病率估计为每年1%。此外，10%的参与者曾感染过乙型肝炎，1%有梅毒血清学证据。在接受调查者中，38%在过去六个月内与固定或非固定伴侣进行过无保护的肛门生殖器性交。
数据表明艾滋病毒正在年轻男同性恋者中传播。鉴于该群体的高风险行为水平，有必要继续对其开展预防活动。
