Partner concurrency increases the risk of sexually transmitted infections (STIs) such as Trichomonas vaginalis. Women diagnosed with T. vaginalis have a 2- to 3-fold higher risk of acquiring the human immunodeficiency virus and developing the acquired immunodeficiency syndrome.
We sought to describe partnership concurrency (multiple sexual partners during the same time period) and condom use among women diagnosed with T. vaginalis, and to compare reports of concurrency between matched female and male dyads.
A baseline interview on partnership status and condom use was administered to women diagnosed with T. vaginalis at a public sexually transmitted infections (STI) clinic. A male partner substudy was also conducted. Seventy-three dyads were matched by unique identifier and female and male responses were compared.
The participants were 319 African American women and 10 white women aged 15-40 years (N = 329). Almost three fourths (72.3%) had only 1 partner over a 3-month period, compared with more than one fourth (27.7%) with > or =2 partners. Regular condom use was low (16.4%), especially with regular partners (9.1%). In the matched substudy, men reported significantly higher rates of concurrency than women (47.3% vs. 23.0%; p < or = .002). Men who practiced concurrency were not significantly more likely than other men to use condoms with regular partners.
Women seldom used condoms with their regular male partners and these partners had significantly higher rates of concurrency and low rates of condom use. Women may underestimate the risk of acquiring STI from regular partners. Counseling strategies should include the risk of being infected with STDs such as trichomonas by regular partners as well as by casual partners in the absence of condom use.
性伴侣的同时性增加了诸如阴道毛滴虫等性传播感染（STIs）的风险。被诊断为阴道毛滴虫感染的女性感染人类免疫缺陷病毒并发展为获得性免疫缺陷综合征的风险要高出2至3倍。
我们试图描述被诊断为阴道毛滴虫感染的女性中的性伴侣同时性（同一时期有多个性伴侣）及避孕套使用情况，并比较配对的女性和男性对偶组之间的同时性报告。
在一家公共性传播感染（STI）诊所，对被诊断为阴道毛滴虫感染的女性进行了关于性伴侣状况和避孕套使用情况的基线访谈。还开展了一项男性性伴侣子研究。通过唯一标识符匹配了73对对偶组，并比较了女性和男性的回答。
参与者为319名非裔美国女性和10名15至40岁的白人女性（N = 329）。在3个月期间，近四分之三（72.3%）的女性只有1个性伴侣，四分之一以上（27.7%）的女性有2个或更多性伴侣。经常使用避孕套的比例较低（16.4%），尤其是与固定性伴侣（9.1%）。在配对子研究中，男性报告的同时性发生率显著高于女性（47.3%对23.0%；p≤0.002）。有同时性行为的男性与其他男性相比，在与固定性伴侣使用避孕套方面并没有显著更高的可能性。
女性很少与她们的固定男性性伴侣使用避孕套，而这些性伴侣的同时性发生率显著更高且避孕套使用率较低。女性可能低估了从固定性伴侣感染性传播感染的风险。咨询策略应包括在不使用避孕套的情况下，被固定性伴侣以及偶然性伴侣感染诸如滴虫等性传播疾病的风险。
