摘要
目的 ]分析济南市儿童骨矿物质含量及其影响因素 ,为儿童合理营养 ,促进发育、预防疾病提供依据。 [方法 ] 1998年采用SD -10 0 0型单光子骨矿物测量仪 ,检测了济南市山东医科大学附属小学与山东师范大学附属小学761名 7～ 13岁健康儿童 (其中正常体重儿童 65 6名 ,中度以上肥胖儿童 10 5名 )左前臂中上 1/3处桡骨和尺骨的骨矿物质含量线密度 (BMC)和面密度 (BMD) ,并测量了身高、体重、胸围、皮脂厚度、肺活量等 ,进行了多元逐步回归分析 ,并比较肥胖儿童与正常儿童桡骨BMD。 [结果 ]桡骨和尺骨的BMC与BMD均随年龄的增长而增加 ,各年龄组桡、尺骨骨矿物质含量BMC差异均有高度显著性。体重和体块指数 (BMI)与骨矿物质含量关系密切。肥胖组骨矿物质含量显著高于对照组。 [结论 ]济南市 7～ 13岁儿童骨发育状况良好 ,体重和体块指数是影响骨矿物质含量的主要因素。
Objective]To make analysis on bone mineral content and its influential factors in children to provide scientific basis for equitable nutrition,accelerated development and prevention of diseases of children.[Methods]Bone mineral content (BMC) and bone mineral density (BMD) were measured in 1998 by single-photon absorptiometry SPA (SD-1000) in 761 healthy children (656 normal weight children,105 obesity children)aged 7～13 years at the one-third distal radius and ulna site on the left arm in Jinan. The height, weight, chest circumference, triceps skin fold thickness and vital capacity were also measured. The data were analyzed by multiple linear regression analysis. BMD was compared in obesity children with normal ones.[Results]The BMC and BMD of radius and ulna increased significantly with age. The BMC of radius was higher than that of ulna in all age groups. BMC was correlated with weight and body mass index (BMI). BMD was significantly higher in the obesity group than in the control. [Conclusions]The bone of children aged 7～13 years in Jinan developed well. The primary factors which influenced bone development were weight and BMI.
