Abstract
The purpose of this study was to declare for Japanese pre-school children′ s growth and was to benefit prevention of life-styled diseases.
Subjects were 40 healthy and free living pre-school children ( males: 20, females: 20 ) aged 3 to 6 years old.
Measurements are four Skinfold Thickness and Circumference, Height, Weight, Sitting-Height and Under-Legs.
As, there was no predicting formula of Body Density and Body Fat Percentage from Skinfold Thickness for Japanese pre-school children.
So, we adapted the two equations for Body Density and the four equations for Body Fat Percentage from the precedence literature on pre-school children.
Survey was performed on January, Febrary, 2003.
Results and Discussion were as follows.
1. Results by Two-way ANOVA, four Skinfold Thickness, Circumference, Height, Weight, Sitting-Height and Under-Legs were not recognized the differences by sex, but increased with ages.
2. The sum of four Skinfold Thickness for pre-school children was females higher than males, and occasion of females, we recognized that the sum of four Skinfold Thickness and Body Fat Percentage increased from about beginning at 5years late. But, calculated Body Fat Percentage from Body Density were widely distributed by the formula. This means that there is the problem about the formula used for Japanese pre-school children. Therefore, it is necessary to consider on body composition, the formula for Japanese pre-school children.
