This paper argues that the notion of sexual partners per se is insufficient for estimating levels of HIV risk behaviour or changes in HIV risk over time, even though it is a crucial element of most epidemiological models of HIV. The concept of a penetrative sexual partner (PSP) is introduced as a considerably more accurate measure of HIV risk. Using data from a longitudinal study of 930 homosexually active men in England and Wales, this paper demonstrates that variation in numbers of PSPs (and thus HIV risk) is not related to variation in the gross numbers of sexual partners.
本文认为，性伴侣这一概念本身不足以用来估计艾滋病毒风险行为水平或随时间推移的艾滋病毒风险变化，尽管它是大多数艾滋病毒流行病学模型的关键要素。本文引入了插入式性伴侣（PSP）这一概念，作为一种更准确得多的艾滋病毒风险衡量标准。利用来自英格兰和威尔士930名有同性恋行为男性的纵向研究数据，本文表明，PSP数量的变化（即艾滋病毒风险）与性伴侣总数的变化无关。
