The objectives of this study were to determine the prevalence of sexually transmitted infection (STIs) in heterosexual couples and the sexual behaviors associated with their acquisition.
The goal of this study was to better direct educational efforts to decrease STI among heterosexual couples in Lima, Peru.
We conducted a case-control study in 195 heterosexual couples without HIV infection who attended 2 sexually transmitted disease clinics in Lima, Peru. A case was defined as an individual with one or more newly diagnosed STIs such as gonorrhea, chlamydia, trichomoniasis, herpes simplex, syphilis, mycoplasma, or ureaplasma.
Thirty-three percent of individuals (41 men and 89 women) had at least one STI and 26 couples (13%) had the same STI detected. Men who have sex with men (MSM) accounted for 13% of all men, had higher rate of STIs and higher risk behaviors than non-MSM. Ureaplasma infection was the most prevalent STI found in both men and women and was associated with oral sexual contact. In heterosexual pairs, condom use during anal sex occurred less than 10% of the time.
The heterosexual couples in sexually transmitted disease clinics have high-risk behaviors and STIs are frequent. The educational effort concerning prevention of STIs requires higher effort.
本研究的目的是确定异性恋伴侣中性传播感染（STIs）的患病率及其感染相关的性行为。
本研究的目标是更好地指导教育工作，以降低秘鲁利马异性恋伴侣中的性传播感染率。
我们对195对未感染艾滋病毒的异性恋伴侣进行了一项病例对照研究，这些伴侣前往秘鲁利马的两家性传播疾病诊所就诊。病例定义为患有一种或多种新诊断的性传播感染的个体，如淋病、衣原体、滴虫、单纯疱疹、梅毒、支原体或脲原体。
33%的个体（41名男性和89名女性）至少患有一种性传播感染，26对伴侣（13%）检测出相同的性传播感染。男男性行为者（MSM）占所有男性的13%，其性传播感染率和危险行为高于非男男性行为者。脲原体感染是男性和女性中最常见的性传播感染，与口交接触有关。在异性恋伴侣中，肛交时使用避孕套的比例不到10%。
性传播疾病诊所中的异性恋伴侣存在高危行为，性传播感染很常见。预防性传播感染的教育工作需要加大力度。
