Provisional standards of height and weight for persons 65 to 94 years of age are here set up on the basis of data from 2,925 men and 2,694 women. All subjects were ambulant, all lived in the community, and all were free from evidence of cardiovascular, renal, or other disease. Weights and heights were measured in stocking feet, and weight included that of light undergarments. For men between the ages of 65 and 69 years the range of stature was from 154 to 185 cm. (61 to 73 in); the average man of this age group was 7 73 cm. (68 in.) tall and weighed 72 kg. (159 Ib.). For women between the same ages the range of stature was from 147 to 175 cm. (58 to 69 in.); the average woman was 160 cm. (63 in.) tall and weighed 64 kg. (141 Ib.). In both sexes and at all heights the average weight became lighter with advancing age. Height, unlike weight, virtually did not diminish with further aging. The authors emphasize that the published figures are averages of actual measurements rather than optimal or ideal figures.
