Abstract
Current information suggests that dietary intake of nutrients declines with age and that undernutrition in elderly long-stay hospital patients may be under-recognized. We undertook to describe the daily dietary intakes of a group of elderly long-stay hospital patients (n = 92) (group A), using 7-day weighed dietary records. The aim of the study was to determine the adequacy of the diet and investigate whether any differences existed in the intakes of the hospital patients. An assessment of nutritional status was carried out by anthropometry, haematology and biochemistry and was validated by comparison with two further groups: fit young subjects (n = 41) (group B) and fit community elderly subjects (n = 92) (group C). Men in group B had the highest mean values for mid-arm circumference, arm-muscle circumference, corrected arm-muscle area and arm-fat area while women in group A had the lowest mean values for all measured anthropometric indices. There were significant correlations between daily energy intake and anthropometry for men in groups B and C. In group A 68% had intakes 6, folic acid; 98% for magnesium and zinc; and 90% for retinol. Serum calcium and serum alkaline phosphatase were correlated with vitamin D intake in men in group A. There was no biochemical or haematological evidence of undernutrition in the three groups. Elderly long-stay hospital patients were grossly undernourished and their dietary intake did not satisfy basal metabolic demands, based on recommended daily allowances.
