作者以85名2～13岁的健康儿童为对象,研究其24h尿肌酐排出量与身体测量指标的关系。结果表明,24h尿肌酐量与下列指标呈高度显著正相关:①年龄(男童:r=0.838,女童:r=0.869);②身高(r=0.915,0.915);③体重(r=0.865,0.927);④臂肌面积。(r=0.689,0.656)。多元回归分析表明,身高和体重为影响24h尿肌酐量的主要因素,其它指标则影响较小。 The author of 85 healthy children aged 2 to 13 years as the object, study its 24h urine creatinine discharge and body measurements. The results showed that there was a highly significant positive correlation between 24h urine creatinine and the following parameters: ① age (boys: r = 0.838, girls: r = 0.869); ② height (r = 0.915,0.915) 0.927); ④ arm muscle area. (r = 0.689, 0.656). Multivariate regression analysis showed that height and weight were the main factors affecting 24h urinary creatinine, while other indexes had less effect.
