常常应用死亡率统计来衡量公共卫生问题的程度、范围和确定各种死因的相对重要性。在此过程中,传统的粗死率和年龄调整死亡率分析起了重要的作用;它们使监测的卫生目标的优先实现和发展成为可能。尽管这些率是美国家卫生状况的重要测量,但它们往往不能反映死亡率随时间变化的全貌。 Mortality statistics are often used to measure the extent and extent of public health problems and to determine the relative importance of various causes of death. In the process, traditional analysis of mortality and age-adjusted mortality plays an important role; they make it possible to prioritize and develop health targets for monitoring. Although these rates are a significant measure of the health status of homes in the United States, they often do not reflect the full picture of the change in mortality over time.
