The present paper describes the changes in physical characteristics of the aged, especially in stature and body weight with increasing age. Samples consisted of 1002 old men and women aged from 63 to 90 years old, and 13.4% of these subjects could be followed up at the interval of more than five years. These cross sectional and longitudinal data were compared with each other. Results obtained cross sectionally revealed that stature for males decreased at the rate of -0.20cm/year, and -0.40cm/year for females. Longitudinal data also resulted in the rate of -0.20cm/year for males, and -0.34cm/year for females. Both results showed that females decreased in stature at the greater rate than males and the effect of secular trend on stature were very little. In contrast with stature, body weight remained relatively stable with age for the followed up subjects, although large reduction were seen in cross sectional data. This cross sectional change in body weight for the aged seemed to be affected by factors except aging.
