本文采用“4日称重记帐法”对焦作矿务局煤矿工人进行了膳食调查,并对其锌、铁、钙的营养状况进行了评价。结果表明:矿工膳食中锌、铁的摄入量是充足的,而钙稍嫌不足,仅能达到供给量标准的74％。通过计算还发现膳食中锌,铁,钙90％以上来源于植物性食物,只有不足10％来源于动物性食物。矿工血清锌、铁、钙的总体水平分别为87.6±20.5μg/dl,160.3±69.3μg/dl,5.9±1.5mg/dl。提示焦作矿务局煤矿工人钙的营养状况很差,需要调整矿工的膳食结构,并注意在膳食中增加钙和VitD的摄入,锌、铁的营养状况尚可。
In this paper, “4-day weighing accounting method” to Jiaozuo Mining Bureau coal miners conducted a dietary survey, and its zinc, iron, calcium nutritional status were evaluated. The results showed that the intake of zinc and iron in miners’ diet was sufficient, while calcium was somewhat deficient, which could only reach 74% of the supply standard. Calculated also found that dietary zinc, iron, calcium and more than 90% from plant foods, less than 10% from animal foods. The overall levels of zinc, iron and calcium in miners were 87.6 ± 20.5μg / dl, 160.3 ± 69.3μg / dl and 5.9 ± 1.5mg / dl, respectively. It is suggested that the coal miners in Jiaozuo Mining Bureau have poor nutritional status and need to adjust the diet of the miners and pay attention to the intake of calcium and VitD in the diet. The nutritional status of zinc and iron is acceptable.
