Nutritional status and performance capacity in internal medical patients.

The nutritional status (3 anthropometric records, serum albumin and delayed cutaneous hypersensitivity (DCH)), recent weight loss, dynamometric capacity and mood were assessed in 205 recently admitted non-cancer internal medical patients. 20% of the subjects were classified as malnourished (3 of the 5 nutritional variables below the reference range). The occurrence of malnutrition was higher (1/3) in multiple organ dysfunction or chronic respiratory disease. In order to reduce the risk of overestimating malnutrition, the data for serum albumin and DCH were omitted when they appeared to be influenced by non-nutritional factors. Disease duration >2 years, old age and multiple organ dysfunction were independently related to malnutrition. Serum albumin correlated more strongly with the acute phase reactant, serum acid glycoprotein (r = 0.33, P < 0.001) than with the anthropometric variables (r < 0.24). Recalled recent weight loss >5% was found in 34% of the malnourished subjects. Malnourished, in comparison to well nourished patients, exhibited reduced (p < 0.05) recordings for hand grip strength, peak expiratory flow and time of ambulation. Depressive tendencies were seen in malnourished women (p < 0.05).
