This study investigated protective effects of circumcision in a sample of immigrant Latino men who have sex with men (MSM). A survey in Portuguese, Spanish, or English was administered with computer-assisted self-interview technology with audio enhancement (A-CASI) to 482 MSM from Brazil (n=146), Colombia (n=169), and the Dominican Republic (n=167), living in the New York metropolitan area. Logistic regression revealed that after controlling for age, income, education, having had syphilis, having done sex work, and preferring the receptive role in anal intercourse, uncircumcised men were almost twice as likely to be HIV-positive as circumcised men. Follow-up analyses revealed, however, that the protective effects occurred only among the group of Colombian men.
本研究调查了包皮环切术对与男性发生性行为的拉丁裔移民男同性恋者(MSM)样本的保护作用。采用计算机辅助自我访谈技术(A-CASI)并配有音频增强功能,用葡萄牙语、西班牙语或英语对居住在纽约大都市地区的482名MSM进行了调查,这些人分别来自巴西(n = 146)、哥伦比亚(n = 169)和多米尼加共和国(n = 167)。逻辑回归分析显示,在控制了年龄、收入、教育程度、曾患梅毒、从事性工作以及在肛交中偏好接受方角色等因素后,未行包皮环切术的男性感染HIV呈阳性的可能性几乎是行包皮环切术男性的两倍。然而,后续分析表明,这种保护作用仅在哥伦比亚男性群体中出现。
