The compression of morbidity debate in aging: an empirical test using the gerontological and geriatric population studies in Göteborg, Sweden (H70)

• The H70 longitudinal study of aging, Göteborg, Sweden is used to empirically test the compression of morbidity theory advanced by [Fries, 1980 and Fries and Crapo, 1981]. We reconceptualize compression as postponement of morbidity in the sense of decreasing amounts of illness for increasingly long life spans. Operationally, morbidity is defined as the average number of hospital days in the last year of life. The date of death and the date of 1-year prior to death define the risk period. The linear regression model with age at death, age at death squared, year of birth, and sex are statistically significant with the oldest having the fewest hospital days. The findings offer partial support for the compression of morbidity theory.
