Measuring health inequality with realization of potential life years (RePLY)
提出一种新方法，通过分离可避免和不可避免的死亡风险来度量政策可干预的健康不平等，并用2000年191国数据发现控制不可避免风险后不平等程度降低，且同等预期寿命的国家间不平等差异显著。
This paper proposes a new method to measure health inequalities that are caused by conditions amenable to policy intervention. The method is built on a technique that can separate avoidable and unavoidable mortality risks, using world mortality data compiled by the World Health Organization for the year 2000. The new method is applied to data from 191 countries. It is found that controlling for unavoidable mortality risks leads to a lower estimate of health inequality than otherwise, especially for developed countries. Furthermore, although countries with a higher life expectancy at birth tend to have lower health inequality, there are significant variations in health inequalities across countries with the same life expectancy. The results therefore support the WHO's plea for using health inequality as a distinct parameter from the average level of health in assessing the performance of health systems.
