The aim of the present study is to summarize existing literature on vitamin D levels in adults in different continents and different countries worldwide. The best determinant of vitamin D status is the serum concentration of 25-hydroxyvitamin D (25(OH)D). Most investigators agree that serum 25(OH)D should be higher than 50 nmol/l, but some recommend higher serum levels. Traditional risk groups for vitamin D deficiency include pregnant women, children, older persons, the institutionalized, and non-western immigrants. This chapter shows that serum 25(OH)D levels are not only suboptimal in specific risk groups, but also in adults in many countries. Especially, in the Middle-East and Asia, vitamin D deficiency in adults is highly prevalent.
本研究旨在总结全球不同大陆和不同国家成年人维生素 D 水平的现有文献。维生素 D 状态的最佳决定因素是血清 25-羟维生素 D（25(OH)D）浓度。大多数研究人员认为血清 25(OH)D 应高于 50nmol/L，但也有一些人建议更高的血清水平。维生素 D 缺乏的传统高危人群包括孕妇、儿童、老年人、机构居民和非西方移民。本章表明，血清 25(OH)D 水平不仅在特定的高危人群中不理想，而且在许多国家的成年人中也是如此。特别是在中东和亚洲，成年人的维生素 D 缺乏症非常普遍。
