Serum Cholesterol Levels as a Measure of Frailty in Elderly Patients

Abstract

The authors evaluated the association between serum cholesterol levels and social, clinical, and functional characteristics in 637 elderly hospitalized patients (mean age = 79.1 years, range = 65-97) from the Geriatric Evaluation and Rehabilitation Unit (GERU) at P. Richiedei Hospital in Gussago, Brescia (Italy). Patients consecutively admitted to the GERU during an 18-month period underwent a multidimensional evaluation including information on demographics, cognitive status, physical health (number of chronic diseases and administered drugs), functional disability, and nutritional status. Mean cholesterol levels were significantly lower in men; persons living with others; older individuals; and individuals with cognitive impairment, poorer somatic health, higher disability, and a higher level of malnutrition. Lower serum cholesterol levels may be considered an independent hematologic marker of frailty in elderly hospitalized patients.
