Improvement in survival at advanced ages suggests that important changes in health and the natural history of disease processes may be occurring concurrently. a general model based upon cohort and life-course perspectives describes the changing relation of morbidity, disability, and mortality over time. Variability across different social and economic conditions is examined among institutionalized and non-institutionalized elderly, and between the United States and Japan. Future policy must take account of the qualitative, as well as the quantitative, changes in aging.
高龄人群生存率的提高表明，健康状况和疾病进程的自然史可能正在同时发生重大变化。一个基于队列和生命历程视角的通用模型描述了发病率、残疾率和死亡率随时间的变化关系。在机构养老和非机构养老的老年人中，以及在美国和日本之间，研究了不同社会和经济条件下的差异。未来的政策必须考虑到老龄化在质量和数量上的变化。
