Abstract

OBJECTIVES: To examine the association between hospitalization and annual changes in body composition and strength in older adults. DESIGN: Cohort study. SETTING: Clinic examinations in Pittsburgh, Pennsylvania, or Memphis, Tennessee. PARTICIPANTS: Well-functioning adults aged 70 to 79 who participated in the Health, Aging and Body Composition Study. MEASUREMENTS: Hospitalizations were reported at annual clinic visits and in semiannual phone interviews. In the event of death or reported hospitalization, hospitalizations were adjudicated according to medical record review. Dual X-ray absorptiometry (DXA) assessments of total, lean, and fat mass were conducted in six annual examinations, and measures of knee extensor strength were conducted in two annual examinations. RESULTS: DXA assessments followed 2,309 hospitalizations. In men and women, hospitalization in the previous year was associated with greater declines in total mass (-0.76 and-0.81 kg, respectively), fat mass (-0.41 and-0.54 kg), and lean mass (-0.33 and-0.25 kg) (P
