Abstract

Several factors, such as disability, malnutrition, weight loss, and the interactive effect of diseases and aging have been associated with morbidity and mortality in the elderly population. Nevertheless, the relationship between disability and biological parameters has not been extensively investigated as a primary focus. In a cross sectional survey, 344 institutionalized elderly subjects were evaluated. Disability was measured according to the Katz index, and patients were divided into three groups: low (0–1 lost ADL), mild (2–4 lost ADL), and severe (5–6 lost ADL). Anthropometric, metabolic, and nutritional parameters were assessed; age, gender, number of pathologies, and number of drugs were also recorded. Data were analyzed by multiple comparison of means according to Scheffé, and by multivariate logistic regression analysis. An impairment in functional status was associated with several modifications in biological parameters. Logistic regression analysis showed that severe disability (5–6 lost ADL) was associated with low waist/hip ratio (<0.9vs >0.9, OR.1.56, CI 95%:1.08–2.25), high body resistance (>625 vs <575 Ω., OR.1.39, CI 95%:1.38-1.39), low plasma albumin levels (<3.5 vs >4.0 g/dL, OR.6.02, CI 95%:5.18–6.85), and low plasma transferrin levels (<200 vs >250 mg/dL, OR:5.47, CI 95%:4.56–4.58) independently of age, gender, comorbidity, and other confounding factors. Our results indicate that severe disability in ADL is strongly associated with anthropometric and biohumoral parameters suggesting the presence of malnutrition. A careful evaluation of the nutritional state appears to be of primary importance, and efforts to improve nutritional status are needed in approaching disabled elderly patients.
