目的比较肚脐上缘1 cm处的水平面(方法1)、腋中线髂骨上缘与第十二肋骨下缘连线的中点(方法2)、经肚脐水平位绕腰1周(方法3)3种腰围测量方法对儿童青少年的测量结果,为儿童青少年腰围测量方法研究提供依据。方法使用3种腰围测量方法对北京市东城区某2所小学六年级196名小学生进行测量,并使用生物电阻抗测量其中72名目测超重学生的脂肪百分比和腹部肥胖情况。结果3种腰围测量方法结果之间差异有统计学意义(P<0.05),方法1的标准差最大。变异系数显示,方法2的区分度最好,方法1次之;方法2所得腰臀比与生物电阻抗的腰臀比结果最接近,方法1次之;方法1与腹部肥胖的相关性最好,方法3次之;方法3与脂肪百分比的相关性最好,方法1次之。结论在肚脐上缘上1 cm的水平面上进行腰围测量的方法在综合性和对腹部肥胖度的反映上优于其他方法。
Objective To compare the water level at 1 cm above the upper edge of the navel (method 1), the midpoint between the upper edge of the iliac crest and the lower edge of the twelfth rib (method 2), and a waist around the navel for 1 week (method 3) The measurement results of three kinds of waist measurements on children and adolescents provide the basis for the study of waist circumference measurement method in children and adolescents. Methods Sixty-six primary school students in two primary schools in Dongcheng District of Beijing were measured by three methods of waist circumference measurement. The bioelectric impedance was used to measure the fat percentage and abdominal obesity of 72 visually-overweight students. Results The results of three kinds of waist measurements showed statistical significance (P <0.05), and the standard deviation of method 1 was the largest. The coefficient of variation showed that method 2 was the best one and the method was the first one. The waist-to-hip ratio obtained by method 2 was the closest to the waist-hip ratio of bioelectrical impedance, and the method was the first one. The correlation between method 1 and abdominal obesity was the best , Method 3 times; method 3 and fat percentage of the best, method 1 times. Conclusion The waist circumference measurement at the level of 1 cm on the upper edge of navel is superior to other methods in comprehensiveness and response to abdominal obesity.
