【摘要】：目的比较6~8岁骨龄段女性儿童不同的体脂率测量方法的效果,尝试建立适合我国该骨龄段女性儿童的皮褶厚度推算体脂率公式。方法抽样选取59名6~8岁骨龄段女性儿童,依据身体质量指数(BMI)分组标准分为偏瘦组、正常组和超重组3个组别,分别采用双能量X线吸收法(DEXA)、皮褶厚度法、生物电阻抗法(BIA)测试每位受试者的体脂率,以DEXA测量结果为校标,比较上述方法在推测和测量全身体脂率的差异水平。并以皮褶厚度法建立体脂率推测公式。结果对6~8岁骨龄段女性儿童正常组和超重组,BIA法与DEXA测量结果之间相关显著;日本长岭公式显著高估6~8岁骨龄段偏瘦组和正常组女性儿童的体脂率,姚兴家公式显著低估了超重组女性儿童的体脂率,而元田恒公式显著高估了3种体型女性儿童的体脂率;本研究得出皮褶厚度法推算体脂率公式为:全身体脂率=3.919+0.715×髂嵴上部皮褶+0.592×肱三头肌部皮褶。结论相对于以日本长岭公式、元田恒公式、姚兴家公式进行的皮褶厚度推算法,生物电阻抗手段更能有效测量6~8岁骨龄段女性儿童正常和超重群体体脂率;髂嵴上部和肱三头肌部皮褶厚度能联合评价6~8岁骨龄段女性儿童全身体脂率。
[Abstract]:Objective to compare the effect of different measurement methods of body fat rate in female children aged 6 to 8 years old, and to establish a formula for calculating skinfold thickness of female children of this bone age segment in China. Methods 59 female children aged 6 to 8 years old were sampled. According to the body mass index (BMI) group, the subjects were divided into three groups: lean group, normal group and superrecombinant group. The body fat rate was measured by dual energy X-ray absorptiometry, skinfold thickness method and bioelectrical impedance method (BIA). The result of DEXA measurement is used as calibration standard. To compare the different levels of body fat rate between the above methods, and to establish the formula of body fat rate by skinfold thickness method. Results there was a significant correlation between the results of DEXA measurement and the normal group of female children aged 6 to 8 years. Japanese Changling formula significantly overestimated the body fat rate of female children in the lean group and normal group. Yao Xingjia formula significantly underestimated the body fat rate of superrecombinant female children, while Yuantian Henggong significantly overestimated the body fat rate of three kinds of female children. In this study, the formula of calculating body fat rate by skinfold thickness method is obtained as follows: the body fat rate is 3.9190.715 脳 upper skin fold of iliac crest 0.592 脳 triceps brachii skinfold. Conclusion compared with the method of calculating skinfold thickness of Japanese Changling formula, Yuanda Henggong formula and Yao Xingjia formula, The bioelectrical impedance method was more effective to measure the body fat rate of normal and overweight female children aged 6 to 8 years old, and the skinfold thickness of upper iliac crest and triceps brachii muscle could be used to evaluate the body fat rate of female children aged 6 to 8 years old.
