We dissected associations between initiation and intensity of substance use and number of sexual partners using pooled data from high school seniors (weighted n = 13,580) who participated in the 1999-2007 Youth Risk Behavior Surveillance System (YRBS), a cross-sectional, nationally representative survey. In multinomial multivariable logistic regressions, number of sexual partners steadily increased as substance use intensified from never use to experimental/new user to heavy use across all substances for both male and females. Severity of substance use is more closely related to, and thus a better indicator of, higher number of sexual partners than age of substance use onset.
我们利用参加 1999-2007 年全国青少年健康危险行为监测系统（YRBS）的高中生（加权 n=13580）的汇总数据，对物质使用的开始和强度与性伴侣数量之间的关联进行了剖析。该监测系统是一项横断面、具有全国代表性的调查。在多项多变量逻辑回归中，男性和女性中，所有物质的使用从未使用到实验性/新使用者再到重度使用者，性伴侣数量随着物质使用的加剧而稳步增加。物质使用的严重程度与性伴侣数量的关系更为密切，因此是衡量性伴侣数量的更好指标，而不是物质使用开始的年龄。
