789例儿童骨密度与奶制品及维生素A、D的关系

本报告是用国产单光子BMD—4型骨密度检测仪测定789例2～8岁正常儿童的骨密度。结果显示:儿童骨密度与年龄成正相关,7岁时出现骨密度增长高峰。骨密度低于一个标准差以上者占受检总数的11.4％。统计学分析结果显示每天饮用牛奶及用维生素A、D组儿童的骨密度明显高于各自的对照组。提示奶制品及维生素A、D的服用,对儿童骨骼生长发育及骨质疏松症早期预防有重要的意义。

RELATIONSHIP BETWEEN THE CONTENT OF BONE MINERAL DENSITY AND DAIRY,VITAMIN AD IN 789 CHILDREN

The bone mineral density (BMD) content of the distal radium of 789 healthy children aged 2-8 has been measured with home-made single photon BMD-4 Bone Density Determiner. The result showed that BMD in the those children was closely correlated with ages,it increased rapidly in the group at the age of 7. The BMD content in 11. 4% out of all those children studied was much lower than normal standard. The statistic' s analytical data reflected that the MBD content in those children who were fed with dairy or vitamin AD was higher than those without using the feedings. Conclusion: It is very important to feed the children before the age 7 with dairy and/or vitamin AD, so that their BMD may be normal. And also, it may be benefits the prevention of osteoporosis for the future.
