Socioeconomic determinants of continuing functional disablement from chronic disease episodes.

Functional disablement of persons with chronic disease is a complex outcome shaped by a variety of medical and socioeconomic factors, including those influencing the competing risk of death from the disease. The increasingly important task of explaining trends in the functional health status of various populations requires more detailed knowledge about the respective roles of these disability determinants. This paper reports the results of an analysis of the determinants of continuing functional incapacity after an episode of heart disease. A proportional hazards regression model is used to estimate the relative effects of socioeconomic and disease factors on the duration of work disablement and functional incapacitation of 976 surviving and nonsurviving patients hospitalized for presumptive myocardial infarction. The analysis shows that socioeconomic variables play a prominent role in disability outcomes, especially in work resumption. Evidence of aging effects on disability prevalence is also found.
