Anthropometric data (triceps skinfold thickness, mid-arm circumference and arm muscle circumference) have been obtained from 114 normal elderly individuals and are presented as a suitable reference range for use in nutritional assessment of the elderly. In males the results did not differ significantly from existing standards for younger men but in females there was a significant difference from similar standards for younger women. These findings suggest that there is an increase in fat and a decrease in lean body mass with advancing age in females but not in males. This difference is discussed.
