Reference values for triceps skinfold thickness, mid arm circumference, arm fat area and corrected arm muscle area for subjects 70 years and over are given. The sample studied was drawn from the records of a single group practice serving a rural township of New Zealand. Of the initial sample of 825 subjects, measurements were completed on 753 (91.3%) subjects. Mid arm circumference was similar in men and women and declined with age. Arm fat area was greater in women than men at all ages except for those 90 years and over where the number of subjects was small. Arm fat area decreased with age in both sexes. Corrected arm muscle area was greater for men than women and declined with age in both sexes. Measurements of AFA and AMA were similar to those found in the American NHANES-1 study but were considerably higher than those found in comparable British studies.
