A new theoretical relation that does not require the constant age-specific mortality ratio assumption is established between the standardized mortality ratio (SMR) and the life expectancy. A set of regression equations is developed from the theoretical relation to derive estimates of the future expectation of life from estimates of the SMR. Curves are presented showing the changes in life expectancy that are associated with a given SMR for individuals aged 25, 45, and 65 years. These results will provide practical applications in estimating remaining life expectancy in epidemiologic studies in which the SMR is the summary statistic. An application is shown for studies in occupational health to develop and illustrate the method.
在标准化死亡率（SMR）和预期寿命之间建立了一种新的理论关系，该关系不需要特定年龄死亡率恒定比率的假设。从该理论关系推导出一组回归方程，以便根据SMR的估计值得出未来预期寿命的估计值。给出了曲线，显示了25岁、45岁和65岁个体的预期寿命与给定SMR相关的变化情况。这些结果将在以SMR作为汇总统计量的流行病学研究中，为估计剩余预期寿命提供实际应用。展示了在职业健康研究中的一个应用，以开发和说明该方法。
