Among a sample of 1,334 urban heterosexuals aged 18-25 from the 1990-1991 National AIDS Behavioral Surveys, 24% report having had more than one sexual partner during the past year. Young men are more than twice as likely as young women, and unmarried respondents are eight times as likely as married respondents, to have multiple partners. A multiple regression analysis of the interaction between race or ethnicity and education indicates that among whites, young people with 12 or more years of education are four times as likely to have multiple partners as are those with less than a high school education; among Hispanics and blacks, educational level is not related to having more than one partner. Among those with multiple partners, approximately 40% never use condoms with primary or secondary partners, and condom use decreases with increasing number of partners.
在1990 - 1991年全国艾滋病行为调查的1334名年龄在18至25岁的城市异性恋者样本中，24%的人报告在过去一年中有不止一个性伴侣。年轻男性有多个性伴侣的可能性是年轻女性的两倍多，未婚受访者有多个性伴侣的可能性是已婚受访者的八倍。对种族或族裔与教育之间的相互作用进行的多元回归分析表明，在白人中，接受12年或以上教育的年轻人有多个性伴侣的可能性是接受高中以下教育的人的四倍；在西班牙裔和黑人中，教育水平与有不止一个性伴侣无关。在有多个性伴侣的人中，约40%的人在与主要或次要伴侣发生性行为时从不使用避孕套，并且随着性伴侣数量的增加，避孕套的使用率会下降。
