To describe the distribution, size and characteristics of formal and non-formal meeting places for gay men in Mexico City, the general characteristics of this population, and the factors influencing HIV status and sexual behaviour among gay men.
Meeting sites for gay men in Mexico City were mapped, and the results were used as a sampling frame for an individual-level survey. For the survey, a random sample of sites was selected using a selection probability proportional to size, with the aim of interviewing approximately 3000 gay men. Multivariate logistic models were constructed to analyse the correlations between the population profile, and characteristics and behaviours related to HIV status.
Mapping produced an estimated population attending these meeting places in Mexico City of about 6000-14 000 gay men, who were mostly young and economically active individuals with higher educational and socioeconomic levels than the average levels of the population as a whole. Approximately 67% of these men reported being tested for HIV at least once, and 30% of the men reported being HIV-positive.
Participants' profile depicted the gay population in Mexico City as a highly educated community with a relatively high socioeconomic level. Despite their exposure to prevention efforts, members of this community reported unsafe behaviours consistent with the high prevalence of self-reported HIV infection.
描述墨西哥城男同性恋者的正式和非正式聚会场所的分布、规模和特征,该人群的一般特征,以及影响男同性恋者 HIV 感染状况和性行为的因素。
对墨西哥城男同性恋者的聚会场所进行了绘制,并将结果用作个人层面调查的抽样框架。在这项调查中,使用与大小成比例的选择概率对随机选择的地点进行了抽样,目的是对大约 3000 名男同性恋者进行访谈。采用多变量逻辑模型分析了人群特征与与 HIV 感染状况相关的特征和行为之间的相关性。
绘制地图估计墨西哥城这些聚会场所的同性恋者人数约为 6000-14000 人,他们大多是年轻且经济活跃的个体,教育程度和社会经济水平高于整个人口的平均水平。这些男性中约有 67%至少接受过一次 HIV 检测,30%的男性报告 HIV 呈阳性。
参与者的概况描述了墨西哥城的同性恋群体是一个受过良好教育、社会经济水平相对较高的社区。尽管他们接触到了预防措施,但该社区的成员报告了不安全的行为,这与自我报告的 HIV 感染率较高相一致。
