To determine the prevalence of sexual behaviour with the risk of HIV transmission among young homosexual men in Amsterdam.
Point prevalence study.
Amsterdam.
Participants were recruited through advertisements and in gay bars and a STD clinic in the period October 1991-1992. A questionnaire regarding sexual behaviour was completed, and blood samples were drawn to test for presence of serological markers of HIV infection, hepatitis B and syphilis.
Enrolled in the study were 154 men (mean age: 25 years). The prevalence of antibodies against HIV was 5% and that of hepatitis B 22%. Receptive anogenital intercourse with steady partners in the previous six months was reported by 60% (74% sometimes without a condom), with non-steady partners by 41% (40% without a condom). The figures for insertive anogenital intercourse were: steady partners: 45% (74%); non-steady partners: 49% (41%). Overall 43% (66/153) reported at least one unprotected anogenital contact in the previous six months. The presence of HIV antibodies was correlated with the number of partners with whom anogenital sexual intercourse was practised.
The HIV prevalence (5%) was relatively low. Considering the high prevalence of unsafe sexual behaviour further spread of HIV infection among young homosexual men is to be expected.
确定阿姆斯特丹年轻男同性恋者中存在感染艾滋病毒风险的性行为的流行情况。
现患率研究。
阿姆斯特丹。
在1991年10月至1992年期间，通过广告、在同性恋酒吧和一家性传播疾病诊所招募参与者。完成一份关于性行为的问卷，并采集血样检测艾滋病毒感染、乙型肝炎和梅毒的血清学标志物。
154名男性（平均年龄：25岁）参与了该研究。艾滋病毒抗体的流行率为5%，乙型肝炎为22%。据报告，在过去六个月中，60%的人与固定伴侣进行过肛门生殖器接受性交（74%的人有时不使用避孕套），41%的人与非固定伴侣进行过此类性交（40%的人不使用避孕套）。插入式肛门生殖器性交的比例分别为：与固定伴侣：45%（74%）；与非固定伴侣：49%（41%）。总体而言，43%（66/153）的人报告在过去六个月中至少有一次无保护的肛门生殖器接触。艾滋病毒抗体的存在与进行肛门生殖器性交的伴侣数量相关。
艾滋病毒流行率（5%）相对较低。鉴于不安全的性行为流行率较高，可以预期艾滋病毒感染在年轻男同性恋者中会进一步传播。
