煤矿工人和从事其他地下开采工作的工人长期在井下作业,由于日照少,容易导致维生素D缺乏。研究证明,维生素D的主要功能是调节钙、磷的代谢,促进钙质吸收和钙、磷离子在细胞外液和血液中的转移,提高血液和组织液中钙、磷的浓度,维持血液中钙、磷的适宜水平,有利于骨质和软骨组织
Coal miners and other workers engaged in other underground mining work long-term underground, due to lack of sunshine, easily lead to vitamin D deficiency. Studies have shown that the main function of vitamin D is to regulate calcium and phosphorus metabolism, promote calcium absorption and calcium and phosphorus ions in the extracellular fluid and blood transfer, increase blood and tissue fluid calcium and phosphorus concentrations, to maintain blood calcium , The appropriate level of phosphorus is conducive to bone and cartilage tissue
