摘　　要：维生素D缺乏是目前社会所面临的严重健康问题。维生素D(VD)是人体不可缺少的一种脂溶性维生素,其主要作用是增加肠钙的吸收利用,对维持各年龄段骨骼健康矿化都起着非常重要的作用。维生素D缺乏在儿童导致佝偻病;在成年人会发生软骨病和骨质疏松。此外近年来发现维生素D缺乏还与肿瘤、糖尿病、心血管疾病等多种疾病的发生有关,使其重新引起了人们的关注。造成现代社会维生素D缺乏的原因是多方面的,主要是由于各种原因导致的阳光照射不足。血中的25(OH)D的水平可以作为了解人体内VD状况的指标,多数学者认为25(OH)D的水平低于30ng/mL为维生素D不足,现代社会维生素D缺乏发生率非常高,推测全球可能有10亿人口患有维生素D缺乏。合理补充维生素D对预防维生素D缺乏是非常重要的。Vitamin D deficiency is major public health problem in modern society.
