Abstract
OBJECTIVES: Emotional health may have an important effect on disease onset, but there has been little work evaluating premorbid emotional health on recovery from disability that results from acute medical events. The aim of this study is to determine whether premorbid emotional health is predictive of recovery in functional ability 1 year after reporting a stroke, heart attack, or hip fracture (event). DESIGN: A prospective cohort study of an older population‐based sample from 1986 to 1992. SETTING: Data are from baseline and six annual follow‐ups of the North Carolina Established Population for Epidemiological Study of the Elderly. PARTICIPANTS: Two hundred forty whites and blacks aged 65 and older who reported a stroke, heart attack, or hip fracture during one of the first five follow‐up interviews and had an increased level of disability at that follow‐up. MEASUREMENT: Improvement in disability in activities of daily living (ADLs) 1 year postevent. RESULTS: High depressive symptoms at baseline showed a significant association with poorer recovery in functional ability 1‐year postevent after adjustments were made for sociodemographic characteristics, smoking status, ADLs at time of event, cognitive status, and prior history of disease. Compared with nondepressed subjects, depressed subjects had an odds ratio (OR) of 0.38 (95% confidence interval (CI) = 0.16‐0.94) for recovery 1 year after reporting a stroke, heart attack, or hip fracture. Additionally, among subjects who reported low depressive symptoms, high positive affect was significantly associated with increased odds of recovery (OR = 2.70, 95% CI = 1.10–6.68), adjusting for the same variables. CONCLUSIONS: Emotional health, independent of other baseline measures, is associated with recovery in functional ability 1 year after a major health event. Our findings suggest that reducing premorbid levels of depressive symptoms or increasing positive affect may help the recovery process. J Am Geriatr Soc 50:713–718, 2002.
