2519例儿童超声骨密度结果分析

Analysis of Bone Mineral Density of 2519 Children by Ultrasound Examination

目的对入院常规体检的儿童进行超声骨密度检测及分析,为儿童低骨密度的预防的时期及性别提供依据.方法选择2014年3月至2015年5月在昆明市儿童医院儿保门诊进行体检的2 519名儿童为研究对象,利用Sunlight公司的Omnisense TM-7 000P超声骨密度测定仪进行检测,按年龄、性别进行分组后分析骨密度结果.结果 （1）SOS随着儿童年龄的增加呈增长趋势,Z值也逐渐增加（P〈0.05）;（2）女性骨密度不足发生率高于男性;（3）骨密度不足发生率以0～6月组最高,7～12月组次之.结论 （1）1岁以内儿童是防治骨量不足的主要人群;（2）防治骨量不足需早期干预,特别是在出生6月内.

Objective To investigate the status of the bone mineral density（ BMD） of children in child health service clinic, to provide reference for the proper period and gender for prevention of the defection of insufficient BMD. Methods Form march 2014 to may 2015, bone mineral density of 2519 healthy children in Kunming children＇s hospital was tested by using sunlight Moistens Tm- Tooo p type of quantitative ultrasound bone density doctor. The BMD values were analyzed according to the age and gender groups. Results（ 1） SOS gradually increased with the age（ P〈0.05）.（ 2） The defection rate of insufficient BMD was higher among girls than among boys.（ 3） The critical period of insufficient BMD was the group of 0 to 6 months, the second was the group of 7 to12 months. Conclusions（ 1） Children less than1 year of age is the main crowd prevention bone deficiences;（ 2） Prevention of bone deficiences need early intervention,especially in the month of birth 6.
