Abstract:

Objective To compare the different measurement methods of the body fat rate for 6-8 years’ bone aged girls,and establish a formula based on the skinfold measurement. Methods Fifty-nine 6-8 years bone aged girls in primary schools were recruited and divided into three groups which were the underweight,normal and overweight groups. Fat rates were tested respectively by dual-energy X-ray absorptiometry(DEXA), bioelectrical impedance method(BIA), and skinfold method. All the data were statitically analysised with SPSS 13.0. Results There was a significant correlation between the BIA and the DEXA measurements in normal and especially in obese girls. Changling formula significantly overestimated the body fat rate in underweight and normal group. Yao Xing-jia formula significantly underestimated the body fat rate in overweight group.Yuan Tian-heng formula significantly overestimated the body fat rate in all three groups. We established a body fat rate formula based on skinfold measurement: body fat percentage=3.919 +0.715 skinfold in waist circumference+0.592 skinfold in triceps. Conclusion For normal and overweight bone-aged 6-8 years’girls, BIA is an effctive way to measure their body fat rate. Changling,Yuan Tian-heng, and Yao Jia-xings’ fomulas showed some deficency in overestamating or underestimateing their body fat rate. Skinfold of waist circumference together with skinfold of triceps may effectively evaluate their body fat rate.
