维生素D除了经典的维持骨骼健康的作用外,还对骨骼外系统发挥重要作用。近年来的研究显示,儿童时期的25羟维生素D水平和脑发育、免疫功能、肥胖、代谢综合征、胰岛素抵抗、感染性疾病、过敏、肿瘤以及心血管疾病等有密切关联,而且这方面的研究已经使人们对维生素D缺乏的定义以及维生素D最佳营养状况的认识发生了改变。鉴于维生素D在儿童健康方面的重要作用,更多的户外活动和维生素D补充是必要的。
In addition to the classic role of vitamin D in maintaining bone health, it also plays an important role in the extra-osseous system. Recent studies have shown that 25-hydroxyvitamin D levels in childhood are closely related to brain development, immune function, obesity, metabolic syndrome, insulin resistance, infectious diseases, allergies, tumors and cardiovascular diseases, etc. In addition, Research has led to changes in the definition of vitamin D deficiency and the best nutritional status of vitamin D. In view of the important role of vitamin D in children’s health, more outdoor activities and vitamin D supplementation are necessary.
