As a means of enhancing public health efforts to control sexual transmission of human immunodeficiency virus (HIV), methods were developed to report on risk behavior in a manner that is comparable and widely interpretable.
An elementary sexual behavior risk index (the vaginal episode equivalent index) that is in accord with some of the essential knowledge about sexual transmission of HIV is described, and a multivariate ordinal risk (MOR) method that can be used to improve such risk indices is introduced.
An example shows that these approaches are applicable to observational studies of seroconversion.
The MOR represents a powerful new tool to develop valid comparable measures of sexual risk behavior and, thereby, to advance HIV prevention research.
为加强公共卫生领域控制人类免疫缺陷病毒(HIV)性传播的工作,已开发出一些方法,以一种可比较且能被广泛解读的方式报告风险行为。
描述了一种基本的性行为风险指数(阴道性行为等效指数),该指数符合一些关于HIV性传播的基本知识,并介绍了一种可用于改进此类风险指数的多变量有序风险(MOR)方法。
一个例子表明,这些方法适用于血清转化的观察性研究。
MOR是一种强大的新工具,可用于制定有效的、可比较的性风险行为测量方法,从而推动HIV预防研究。
