Abstract:
|
Lin & Johnson (Statistics in Medicine 2006) proposed a method of assessing the contribution of diseases (of underlying causes of death) to disparities in life expectancy among populations. Their methodology was derived by computing differences in life-years lost from diseases in the population, in contrast to other widely used methods (Arriaga 1984, 1989 Pollard 1982, 1988) which decomposed life expectancy differences by age group and then by disease. Note that a disease's contribution to the difference in life expectancy is restricted to the expected life-years, whereas the differences in life-years lost due to the disease are accumulated throughout all subsequent ages. A new method is proposed which directly accesses the underlying contribution of diseases. Data from the National Longitudinal Mortality Study will be used to illustrate the differences in the estimates from these methods
