The distribution of supposed indicators of nutritional status in elderly patients

The results of a survey of indicators of nutritional status in patients on admission to wards in the Department of Health Care of the Elderly in Nottingham are reported. Results outside conventional limits of normality are common. Little or none of the observed variance in the biochemical indicators in this population is explained by age or sex. Weight, mid-arm circumference, triceps skinfold thickness, albumin, retinol binding protein and retinol tend to be lower in patients who subsequently die, in patients who are clinically classified as thin or wasted, in patients with poor appetites and in patients with a diagnosis of malignancy. Plasma vitamin C, erythrocyte glutathione reductase activation coefficient and erythrocyte transketolase activation coefficient do not show these trends and are likely to be determined by different factors.
