An individual's risk of sexually transmitted infections (STIs) has been associated empirically with the individual having concurrent sexual partners (individual's concurrency) and, theoretically, with the individual's partner having concurrent partners (partner's concurrency).
The goals of this study were to assess the relationship of STI to individual's concurrency, the partner's concurrency, and awareness of the partner's concurrency.
We recruited 192 individuals aged 18 to 30 from sexually transmitted disease and family planning clinics in 96 partner dyads that reported first sexual contact during the previous 3 months. All individuals underwent computer interviews and testing for Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis. Individuals' self-reports of concurrency and perceptions of partners' concurrency were compared within dyads by kappa statistic; associations of STI with individual's concurrency, partner's concurrency, and knowledge of partner's concurrency were examined using chi-squared analysis, t tests, and multivariate logistic regression.
Only 26% of individuals whose partners had other partners were aware of this (kappa = 0.17 for agreement of perceptions vs. partners' reports of concurrency). In multivariate models, STI in individuals was independently associated with partners' concurrency (odds ratio [OR], 3.6), lack of awareness of partner's concurrency (OR, 4.5), perceiving a partner to have concurrent partners when the partner did not (OR, 4.7), living in south San Diego, and sexual contact within 1 week of acquaintance, but not with individuals' concurrency.
This study demonstrates that STI is associated with partner's concurrency and with not knowing one's partner's behavior.
根据经验，个体性传播感染（STIs）风险与该个体拥有多个性伴侣（个体的性伴重叠情况）相关，从理论上来说，也与该个体的性伴侣拥有多个性伴侣（伴侣的性伴重叠情况）有关。
本研究的目标是评估性传播感染与个体的性伴重叠情况、伴侣的性伴重叠情况以及对伴侣性伴重叠情况的知晓度之间的关系。
我们从96对伴侣中招募了192名年龄在18至30岁之间的个体，这些伴侣来自性病和计划生育诊所，且报告在前3个月内有过首次性接触。所有个体均接受了计算机访谈，并接受了沙眼衣原体、淋病奈瑟菌和阴道毛滴虫的检测。通过kappa统计量在伴侣对中比较个体对性伴重叠情况的自我报告以及对伴侣性伴重叠情况的认知；使用卡方分析、t检验和多因素逻辑回归来检验性传播感染与个体的性伴重叠情况、伴侣的性伴重叠情况以及对伴侣性伴重叠情况的知晓度之间的关联。
伴侣有其他性伴侣的个体中，只有26%的人知晓这一情况（对认知与伴侣性伴重叠情况报告的一致性，kappa = 0.17）。在多因素模型中，个体的性传播感染与伴侣的性伴重叠情况（比值比[OR]，3.6）、对伴侣性伴重叠情况缺乏知晓度（OR，4.5）、在伴侣没有多个性伴侣时却认为伴侣有多个性伴侣（OR，4.7）、居住在圣地亚哥南部以及在相识1周内有性接触独立相关，但与个体的性伴重叠情况无关。
本研究表明，性传播感染与伴侣的性伴重叠情况以及不了解伴侣的行为有关。
