低水平的维生素D在儿童中很常见
发表在美国临床营养杂志发现许多孩子可能有风险维生素D不足。维生素D对于正常生长，发育和免疫功能至关重要。
Researchers from the Children’s Hospital of Philadelphia assessed dietary and supplemental vitamin D intake, body mass, and blood levels of vitamin D in 382 healthy children (ages 6 to 21) living in the northeastern U.S. More than half of the children had low blood levels of vitamin D, with 55 percent having inadequate vitamin D blood levels and 68 percent having low blood levels of vitamin D in the wintertime. African Americans, children 9 and older, and those with low dietary vitamin D intake were most likely to have reduced serum vitamin D levels.
主要研究人员指出：“一个人的维生素D状态的最佳指标是维生素D化合物的血液水平，称为25-羟基维生素D。”“维生素D缺乏症总体上仍然是一个识别的问题，儿童的研究尚未得到很好的研究。”
研究人员补充说，需要进一步的研究来确定儿童中维生素D的适当血液水平，还提出了对当前维生素D摄入建议的综述。
