The morbidity compression theory proposes that we can compress the period of illness and disability in old age into an ever smaller period at the end of life. Although recent research offers fresh support for the theory, its validity remains uncertain. This paper demonstrates the importance of the theory and recent research in this area for women. It critiques the chief proponent and opposing views of the theory, and suggests a heightened emphasis on public policies promoting healthy lifestyles. These policies would reduce long-term care needs, save health care dollars, and improve the experience of aging.
