本文研究了煤矿工人的营养状况。膳食调查结果表明:矿工每日膳食中蛋白质、脂肪、钙、铁、VB_1、VPP摄入量充裕,生热营养素比例基本合理,但热能、VA、VB_2和VC摄入不足。生化检验显示,机体VB_1营养状况良好,VB_2和VC则显缺乏,血红蛋白含量亦低于正常值。此外,由于矿工劳动强度较大,24h尿肌酐排出量明显增高。
This paper studies the nutritional status of coal miners. The results of dietary survey showed that daily intake of protein, fat, calcium, iron, VB_1 and VPP in miners was adequate, and the proportion of heat - generating nutrients was basically reasonable, but the intake of calories, VA, VB_2 and VC was not enough. Biochemical tests showed that the body VB_1 nutritional status is good, VB_2 and VC were significantly lacking, hemoglobin content is also lower than normal. In addition, due to the greater labor intensity of miners, 24h urinary creatinine excretion was significantly increased.
