| 中文摘要: |
| 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的主要作用是增加肠钙的吸收，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。近年来发现除了传统的骨骼系统的作用外，维生素D缺乏还与多种疾病的发生有关。VD缺乏累及的人群非常广泛，可以发生在各个年龄阶段，特别是孕妇。造成孕期维生素D缺乏的主要原因是多方面的，主要是由于各种原因导致的阳光照射不足以及孕期VD的需求量增加所致。孕妇VD缺乏可能与胎儿及新生儿的多种不良状况有关，如影响胎儿及新生儿骨骼系统和大脑的发育，还可能与心脏疾病和I型糖尿病等的发生有关。因此，合理补充维生素D，预防孕期VD缺乏对提高产科质量以及母婴保健是非常重要的。 |
