在最近的工作中，集中指数被广泛用作衡量与收入有关的健康不平等的一个指标。本说明的目的是利用1995年对澳大利亚一般人口进行的SF-36调查收集的数据，说明分解总体健康集中指数的两种不同方法。为了简单起见，我们专注于SF-36的身体功能量表。首先，我们检查分解“由组件”分离的浓度指数的身体功能量表到十个项目，它是基于。结果表明，这些项目对总体不平等措施的贡献不同，即其中两个项目分别对总体措施贡献了13%和5%。其次，为了说明“分组”方法，我们将集中度指数按就业状况进行分解。这涉及将人口分为两类：目前就业的个人和目前没有就业的个人。我们发现，这些群体之间的不平等大约是每个群体内部不平等的五倍。这些方法提供了对不平等性质的深入了解，可用于为政策设计提供信息，以减少与收入有关的健康不平等。版权所有（C）2002约翰威利父子有限公司
In recent work, the concentration index has been widely used as a measure of income-related health inequality. The purpose of this note is to illustrate two different methods for decomposing the overall health concentration index using data collected from a Short Form (SF-36) survey of the general Australian population conducted in 1995. For simplicity, we focus on the physical functioning scale of the SF-36. Firstly we examine decomposition 'by component' by separating the concentration index for the physical functioning scale into the ten items on which it is based. The results show that the items contribute differently to the overall inequality measure, i.e. two of the items contributed 13% and 5%, respectively, to the overall measure. Second, to illustrate the 'by subgroup' method we decompose the concentration index by employment status. This involves separating the population into two groups: individuals currently in employment; and individuals not currently employed. We find that the inequality between these groups is about five times greater than the inequality within each group. These methods provide insights into the nature of inequality that can be used to inform policy design to reduce income related health inequalities. Copyright (C) 2002 John Wiley Sons, Ltd.
