摘　　要：目的研究0~3岁不同性别、不同年龄组儿童骨密度状况,为监测儿童钙营养和骨健康提供依据。方法随机抽取在儿童保健门诊进行健康体检的的4551名0~3岁健康儿童进行超声骨密度检测,根据同年龄、同性别骨密度Z值的评分数分为正常、轻度不足、中度不足、重度不足。结果男童骨密度Z值高于女性,骨密度不足检出率女童高于男童,不同性别间比较差异有统计学意义（χ2=102.11,P〈0.001）;年龄越小,骨密度不足检出率越高。不同年龄组儿童骨密度值比较差异有显著性（χ2=595.35,P〈0.001）。结论 1岁之内的婴儿是防治骨密度不足的主要人群,生后6个月婴儿是防治骨密度不足的关键期。Objective To investivate the status of the bone mineral density（ BMD） of children aged 0-3 years,to provide reference for the surveillance of children’s calcium nutrition and bone health. Methods A simple sampling was conducted in child health service clinic,and 4551 healthy children between 0-3 year-old were selected randomly to participate the ultrasonic bone densitometry.The BMD values were judged by Z-score for age and gender and were classified into four categories： normal,mild insufficient,moderate insufficient and severe insufficient. Result The Z-score was higher among boys than among girls. The detection rate of insufficient BMD was higher among girls than among boys,the difference was statistically significant（ χ2= 102. 11,P 〈 0. 001）. The smaller the age,the higher the detection rate of insufficient BMD,the difference of the BMD among different age groups was statistically significant（ χ2= 595. 35,P 〈 0. 001）. Conclusion Infant is the major population of insufficient BMD prevention,especially the first six months is the critical period.
