This study examined the prevalences of antibodies to Treponema pallidum, Chlamydia trachomatis, and herpes simplex virus type 2 in a sample of Peruvian adults.
Among adults seeking health certification in Lima, Peru, 600 were randomly selected to undergo interviews and serologic testing.
Men's reported mean lifetime number of partners (10.6) far exceeded women's (1.1), yet antibody to sexually transmitted infection pathogens among sexually experienced participants was 2.8 times more prevalent among women than among men. Among men, female sex workers accounted for 37% of recent partners, and only sex with female sex workers while using condoms less than half of the time was independently associated with antibody (odds ratio = 3.6, 95% confidence interval = 1.5, 8.8). among women, number of partners was associated with any sexually transmitted infection antibody, while intercourse before 18 years of age was associated with C trachomatis antibody. At every level of perceived risk, sexually transmitted infection antibody was more frequent among women.
Men having unprotected sex with female sex workers had the greatest risk of acquiring infections and (by inference) of transmitting them to women.
本研究调查了秘鲁成年人样本中梅毒螺旋体、沙眼衣原体和2型单纯疱疹病毒抗体的流行情况。
在秘鲁利马寻求健康证明的成年人中，随机选取600人进行访谈和血清学检测。
男性报告的平均终身性伴侣数量（10.6）远远超过女性（1.1），然而，在有性经历的参与者中，性传播感染病原体抗体在女性中的流行率是男性的2.8倍。在男性中，女性性工作者占近期性伴侣的37%，只有在与女性性工作者发生性行为时使用避孕套的时间少于一半才与抗体独立相关（比值比=3.6，95%置信区间=1.5，8.8）。在女性中，性伴侣数量与任何性传播感染抗体相关，而18岁之前的性交与沙眼衣原体抗体相关。在每一个感知风险水平上，性传播感染抗体在女性中更为常见。
与女性性工作者进行无保护性行为的男性感染并（由此推断）将感染传播给女性的风险最大。
