摘要: 目的 分析不同年龄、不同性别婴幼儿骨强度的结果,为预防儿童低骨密度提供依据。方法 随机选取2 083例0~3岁婴幼儿,采取定量超声法测定胫骨中断的Z值,并按照不同性别及年龄分组进行骨密度的比较。结果 男童骨密度Z值明显高于女童,男童骨密度不足检出率低于女童,差异有统计学意义(P<0.05);婴幼儿年龄越小,骨密度Z值越低,骨密度不足检出率越高,差异均有统计学意义(P均<0.05)。结论 婴幼儿骨密度值受性别及年龄因数的影响,对1岁内尤其是6个月以内婴儿定期进行生长发育和骨密度监测,早期预防骨密度不足。

Abstract: Objective To analyse the Results of bone mineral density( BMD) of 0~3 years old infants in different ages and gender and to provide evidence for the prevention of insufficient BMD. Methods A total of 2 083 healthy children were enrolled in the study.All the infants were tested the z scores of the middle point at the tibia with ultrasound techniques.The Z scores and BMD were compared according the ages and gender. Results Z scores in male were significantly much higher than those in female.The incidence of insufficient BMD in males was significantly lower than that in females (P<0.05).The Z scores of BMD decreased with ages.There was significant difference in different ages(all P<0.05). Conclusion The BMD Results of infants are influenced by ages and gender.Infants,especially below 6 months,need growth surveillance and the test of BMD periodically to prevent insufficient bone mineral density at later age.
