The purpose of this paper is to make clear a comprehensive relationship between two groups of measurements of blood pressure and physical constitution. The first group of measurements include pulse rate, systolic blood pressure and diastolic blood pressure, and the second group of measurements include height, weight, chest circumference, circumference of the upper arm and sitting height.These figures are taken from the Nutrition Survey of Japanese, including 6617 males and 8909 females, investigated in May, 1961.Appling the canonical correlation analysis, we found the following results.1) Only two canonical correlations were statistically significant.2) The value of the first canonical correlation was 0.262 for males and 0.381 for females. The corresponding canonical variables were considered as a blood pressure factor and a physical type factor, respectively.3) It seemed that, as the physical type factor changed with age, the blood pressure factor also changed proportionately.4) The value of the second canonical correlation was rather small but significant, 0.094 for males and 0.108 for females. The corresponding canonical variables seemed to be a pulse-pressure factor and a second physical type factor related to weight (positive) and chest circumference (negative).5) In addition, it was also found that the pulse rate has little to do with the physical type.
