钙摄入量对骨密度影响的研究

A study of the relationship between the amount of calcium intake and bone density

[目的 ] 探讨膳食营养与骨质疏松的关系。 [方法 ] 应用膳食营养调查方法调查某厂女工的膳食营养情况 ,并在 40岁以上 3个年龄组女工中分成平时注意补钙和不注意补钙的 2组人群 ,分别对这 2组人群的钙摄入量和骨密度进行比较。 [结果 ] 各年龄组女工的钙摄入量不足 ;40岁以上各年龄组女工中 ,平时注意补充钙摄入的女工每日钙的摄入量均高于未注意补充钙组 ,骨密度也高于未补充钙组。 [结论 ] 膳食钙摄入不足 ,易致骨密度下降。骨质疏松与低钙饮食有关。

Objcetive] To discuss the relationship of food nutrition with osteoporosis. [Methods] Food nutritional investigation method was utilized to investigate the diet nutritional status of different aged female worker groups. In different aged female worker groups 40, 50, 60 they were separated into calcium replenishing group popu lation and calcium non-replenishing group population. The amount of calcium intake of two groups population were compared and the bone density of the two groups population were compared too. [Results] Generally the calcium intake in food of all aged female worker groups was lowered. Those with calcium replenishing group population had a higher amount of calcium than that of calcium non-replenishing group population. The estimated value of bone density of calcium replenishing group popu- lation was higher than those of calcium non-replenishing group population. [Conclusion] It was generally acknowle- dged that inadequate amount of calcium intake in the food was liable to induce the lowering of bone density. Therefore osteoporosis was correlated with low calcium diet.
