Summary

Vitamin D deficiency has become one of the most prevalent health problems in modern society. However, there has been no study that has reported the trend of vitamin D status in Asia. This study investigated the trend of vitamin D status in Korea between 2008 and 2014.

This study is based on a representative national database acquired from the Korea National Health and Nutrition Examination Surveys (KNHANES) conducted from 2008 to 2014. Serum 25-hydroxyvitamin D \[25(OH)D\] levels were measured by radioimmunoassay among those aged 10 yrs or older. The temporal change of vitamin D status will be statistically analyzed.
