Studies on the Physical Surface Area of Japanese

Abstract

Various calculation formulas of body surface area are designed by the measured values of body surface area and other physical measurements, e.g. height, weight, chest circumference etc, of 201 Japanese of both sexes from neonatal to old age. Statistically comparing the formulas, the following three may be used for all ages of Japanese with the slightest possibility of error. 1. Newborn (under 1 year) S=W0.473×H0.655×95.68 2. Young child (1-5 years) S=W0.423×H0.362×381.89 3. Over 6 years to old age (for general use) S=W0.444×H0.663×88.83 (S: Surface area in cm2, W: Body weight in kg, H: Height in cm)
