摘　　要：目的研究沈阳地区5岁以上儿童骨密度变化规律，了解该地区儿童骨密度的正常参考范围。方法选择2003～2007年在沈阳市儿童医院儿保门诊进行体检的5～15岁健康儿童及青少年为研究对象，利用美国LUNAR公司生产的DPX．NT型双能X线骨密度仪进行检测。结果各年龄纽儿童骨密度与其年龄（r=0.997，P〈0．001）、身高（r=0．983，P〈0．001）呈显著正相关，在青春期前（8～12岁）男女骨密度有显著性差异（P〈0．01）。结论骨密度受年龄、性别影响，可作为儿童期钙营养的判定指标。Objective To investigate change trend of bone density among children aged over 5 years old in Shenyang city and to determine a normal reference range of bone density of children in the city. Methods The healthy children and teenagers aged 5 ～ 15 years old who came to our Child Health Clinic for routine physical examination from 2003 to 2007 were selected as study subjects. Dual energy X-ray absorptionmetry （ DPX-NT, LUNAR Co. hd, US） was applied to detect bone density of the children and teenagers. Results In each age group, bone density was correlated positively with age （r = 0. 997, P 〈 0. 001 ） and height （ r = 0.983, P 〈 0.001 ） of the children. In prepuberal phase （8 -12 years old）, there was significant difference in bone density between the two gender groups （P 〈0. 01）. Conclusion Bone density is affected by age and gender.
