根据一个大的国家抽样进行的后续研究被用来审查不同收入水平的收入与死亡率之间的既定反梯度的差异。研究表明，在调整其他社会经济变量之前和之后，在工作年龄（25至64岁）和老年（65岁以上）人口中，高收入水平的收入-死亡率梯度比低收入至中等收入水平的收入-死亡率梯度小得多。此外，处于极端贫穷水平的工作年龄妇女的梯度比处于中低收入水平的妇女的梯度大得多。老年人的收入-死亡率梯度比工作年龄人口小得多。该研究还考察了几种不同的收入数学函数描述收入与死亡率之间关系的能力。这项研究表明，随着收入的增加，与收入增加有关的健康福利会减少。
A follow-up study based on a large national sample was used to examine differences in the well-established inverse gradient between income and mortality at different income levels. The study showed the income-mortality gradient to be much smaller at high income levels than at low to moderate income levels in the working age (25 to 64 years) and elderly (over 65 years) populations for men and women both before and after adjustment for other socioeconomic variables. In addition, a much larger gradient existed for working age women at extreme poverty levels than for those women at low to moderate income levels. The income-mortality gradient was much smaller in the elderly than in the working age population. The study also examined the ability of several different mathematic functions of income to delineate the relationship between income and mortality. The study suggested that the health benefits associated with increased income diminish as income increases.
