Equation for estimating percent fat of Japanese men / 体力科学

ABSTRACT

Forty-two anthropometric measurements were evaluated to determine total body water and percent fat of 71 adult males under 19-77 years of age. Deuterium oxid (D<SUB>2</SUB>O) dilution method was used to determine total body water. A step-wise multiple regression analysis of the data indicated that total body water and percent fat could be predicted from body surface area. Twenty-seven additional boys were tested to increase the sample size. Using the data from these 98 subjects, a step-wise multiple regression analysis gave an equation which yielded a multiple R=0.963 between the predicted total body water and the actual total body water as determined by D<SUB>2</SUB>O dilution method. The standard error of estimate was 1.92 water units and 4.55 percent fat units, respectively. These results indicate that the equation obtained provide an accurate method of body composition estimation when used on a population of Japanese men.
