If men and women engage in different sexual behavior with main partners than with other types of partners, then programs aimed at preventing the spread of sexually transmitted diseases (STDs) may need to address individuals' differential risk with each partner type.
Relationship characteristics, partner risk behaviors and sexual behaviors are examined among 123 male and 106 female STD clinic patients who had both main and other partners. Individual-level comparisons are made for two types of partner pairs: main vs. other frequent (side) partners and main vs. casual partners.
Among men and women with both main and side partners, the proportion who had known only their main partner for at least a year (48% of men and 41% of women) was significantly higher than the proportion who had known only their side partner for that long (2% and 9%, respectively); no other variable differed significantly by partner type. Among those with main and casual partners, both men and women were more likely to use alcohol or drugs before or during sex with main partners only (15%) than with casual partners only (1-3%). Women with main and casual partners were more likely to have oral sex only with main partners than only with casual partners (37% vs. 3%), and were more likely to use condoms only with casual partners than only with main partners (33% vs. 4%).
Providers need to ask individuals about their sexual behaviors with different partner types, and should tailor prevention messages to an individual's risks and reproductive intentions with each partner.
如果男性和女性与主要伴侣的性行为不同于与其他类型伴侣的性行为，那么旨在预防性传播疾病（STD）传播的项目可能需要针对个体与每种伴侣类型的不同风险。
对123名男性和106名女性STD门诊患者进行了研究，这些患者既有主要伴侣，也有其他伴侣。对两种伴侣类型进行个体层面的比较：主要伴侣与其他频繁（次要）伴侣，以及主要伴侣与偶然伴侣。
在既有主要伴侣又有次要伴侣的男性和女性中，只认识其主要伴侣至少一年的比例（男性为48%，女性为41%）显著高于只认识其次要伴侣至少一年的比例（分别为2%和9%）；没有其他变量因伴侣类型而有显著差异。在既有主要伴侣又有偶然伴侣的人群中，男性和女性在仅与主要伴侣发生性行为之前或期间使用酒精或药物的可能性（15%）高于仅与偶然伴侣发生性行为的可能性（1 - 3%）。既有主要伴侣又有偶然伴侣的女性仅与主要伴侣进行口交的可能性高于仅与偶然伴侣进行口交的可能性（37%对3%），并且仅与偶然伴侣使用避孕套的可能性高于仅与主要伴侣使用避孕套的可能性（33%对4%）。
医疗服务提供者需要询问个体与不同伴侣类型的性行为情况，并应根据个体与每种伴侣的风险和生殖意愿调整预防信息。
