在非洲和东南亚，以金钱或物品换取性行为的异性伴侣关系是一个众所周知的艾滋病毒风险因素，但在美国，关于交换伙伴关系及其对艾滋病毒感染的影响的研究较少。在我们的研究中，男性和女性是在2006-2007年间通过受访者驱动的抽样从纽约市高危社区招募的。我们研究了在过去一年中与交换伙伴相关的因素，交换伙伴与艾滋病毒感染之间的关系，以及那些有交换伙伴的人通过支付方向的风险特征。总体而言，28%的男性和41%的女性有过去一年的交换伴侣。对于男性来说，与交换伙伴关系独立相关的因素是年龄较大、性伴侣总数较多、男性伴侣以及频繁使用非注射毒品。对于女性来说，无家可归、更多的性伴侣、更多的无保护的性伴侣以及频繁的非注射毒品使用是影响女性健康的因素。对于男性和女性来说，交换伙伴关系都与艾滋病毒感染有关，尽管这种关系实际上受到其他行为风险的干扰。那些同时买卖性爱的人在交换和非交换伴侣之间表现出最高水平的风险。交易所伙伴关系可能是直接和间接的艾滋病毒风险，因为这一现象与交易所和非交易所伙伴发生的其他风险因素重叠。
Heterosexual partnerships involving the trade of money or goods for sex are a well-described HIV risk factor in Africa and Southeast Asia, but less research has been conducted on exchange partnerships and their impact on HIV infection in the United States. In our study, men and women were recruited from high-risk risk neighborhoods in New York City through respondent-driven sampling in 2006-2007. We examined the factors associated with having an exchange partner in the past year, the relationship between exchange partnerships and HIV infection, and the risk characteristics of those with exchange partners by the directionality of payment. Overall, 28% of men and 41% of women had a past-year exchange partner. For men, factors independently associated with exchange partnerships were older age, more total sexual partners, male partners, and frequent non-injection drug use. For women, factors were homelessness, more total sexual partners, more unprotected sex partners, and frequent non-injection drug use. Exchange partnerships were associated with HIV infection for both men and women, although the relationships were substantially confounded by other behavioral risks. Those who both bought and sold sex exhibited the highest levels of risk with their exchange and non-exchange partners. Exchange partnerships may be an HIV risk both directly and indirectly, given the overlap of this phenomenon with other risk factors that occur with both exchange and non-exchange partners.
