目的:观察10个月～3岁的婴幼儿骨密度测量值,分析相关影响因素。方法:应用超声骨强度测量仪测量110例婴幼儿骨密度,并对所有婴幼儿家长进行问卷调查。结果:婴幼儿SOS值与月龄呈明显正相关。89例(80.91%)婴幼儿骨密度在正常范围。男女婴幼儿间骨量减少差异不具有统计学意义(P>0.05)。母孕期未补钙、产后小儿未予补钙、低龄、单纯母乳喂养等与婴幼儿骨量减少有关。结论:多数婴幼儿骨密度在正常范围,临床应注意母孕期及产后给予小儿补钙,并注意混合喂养。
OBJECTIVE: To observe the measurement of bone mineral density (BMD) in infants and young children aged 10 months to 3 years and analyze the related factors. Methods: Bone mineral density (BMD) was measured in 110 infants and young children by ultrasonic bone strength meter. Questionnaires were also made on all infants and toddlers. Results: There was a significant positive correlation between infant SOS and age. 89 cases (80.91%) of infants and young children with bone mineral density in the normal range. There was no significant difference in bone mass loss between boys and girls (P> 0.05). Not pregnant during pregnancy calcium, postpartum children without calcium, age, pure breastfeeding and other related to bone loss in infants and young children. Conclusion: The majority of infants and young children with bone mineral density in the normal range, should pay attention to the clinical pregnancy and postnatal calcium supplementation in children, and pay attention to mixed feeding.
