To describe sexual behavior patterns and identify psychosocial and situational correlates of safer practices among men who have sex with other men in Lima.
A cross-sectional survey.
In 1992, 223 mostly young, working- and middle-class homosexually active men in Lima, who reported either being seronegative or not knowing their HIV status, were recruited from public places, gay organizations and through snowballing techniques. Measurements included patterns of sexual behavior and socialization with other homosexually active men, and psychosocial and situational factors. Three risk behavior indicators were used: the practice of unprotected receptive anal intercourse, the practice of unprotected anal intercourse (insertive or receptive) and an index of behavioral risk based on numbers of sexual partners for different risk practices.
The subjects (mean age 24.9 years, SD 6.3) were mostly exclusively homosexual (74%) and self-identified as gay/homosexual (73%); 41% had had unprotected anal intercourse during the last 4 months (75% of them in the receptive role). Reporting sex in public places consistently predicted riskier behavior by any of the three indices, whereas a lower perception of benefits of condoms/safer sex, poor AIDS knowledge, participation in a steady relationship and higher self-efficacy were associated with one or two of the indices.
Besides considering basic AIDS information and the promotion of condoms and safer sex, intervention programs for homosexually active men in Lima should emphasize the need for open discussions on safety in steady relationships, promote accurate perceptions of personal risk and sensitively address the special difficulties posed by sexual activity in public places.
描述性行为模式,并确定利马男男性行为者中安全性行为的社会心理和情境相关因素。
横断面调查。
1992年,从公共场所、同性恋组织并通过滚雪球技术招募了223名主要为年轻的、工作及中产阶级的有同性恋行为的男性,他们报告自己血清学检测呈阴性或不知道自己的艾滋病毒感染状况。测量内容包括性行为模式、与其他有同性恋行为男性的社交情况,以及社会心理和情境因素。使用了三个风险行为指标:无保护的被动肛交行为、无保护的肛交行为(主动或被动)以及基于不同风险行为性伴侣数量的行为风险指数。
研究对象(平均年龄24.9岁,标准差6.3)大多为纯粹同性恋者(74%),且自我认定为男同性恋者(73%);41%的人在过去4个月中有过无保护的肛交行为(其中75%为被动方)。在公共场所进行性行为始终预示着在这三个指标中的任何一个上有更危险的行为,而对避孕套/安全性行为益处的较低认知、艾滋病知识匮乏、处于稳定关系中以及较高的自我效能感与其中一两个指标相关。
除了考虑基本的艾滋病信息以及推广避孕套和安全性行为外,针对利马有同性恋行为男性的干预项目应强调在稳定关系中就安全性展开公开讨论的必要性,促进对个人风险的准确认知,并敏感地应对在公共场所进行性活动所带来的特殊困难。
