For the purpose of clarifying the diurnal change of the human height measurements, the stature, cervicale height and right spina iliaca anterior superior height of 10 female students (19-26 years of age) were taken twice in one and another day. The measurement was practiced at 22 o'clock and every 2 hr from 6 (just after the hour of rising) to 16 o'clock on the following day, i.e., 14 times for each subject.
The Variance Analysis Method was made using 3 factors; measurement hours (6 levels), subjects (10 levels), and measurement dates (2 levels). Reduction occured on the stature, head and cervical height, and lower limb height were discussed respectively.
The following conclusions were obtained :
1) The diurnal change takes place mainly on the trunk.
2) Total reduction of the stature from 6 to 16 o'clock is 1.5 cm on an average. Sixty % of that occurs about 8 o'clock and 80% of that does about 10 o'clock.
3) It is desirable to avoid the stature measurement within 3 hr after rising, because the physiological statural reduction during this period exceeds the measurement errors.
