The essentiality of vitamin D and Se in human nutrition have been well known. Their deficiencies in elderly were commonly suggested to increase the risks of cardiovascular disease, osteoporosis, dementia, sarcopenias etc. The dietary Se intake depends on the Se content of consumed foods and dietary pattern of a population. The food Se contents depend on Se status in soil, so they show wide variation even in the same food item. Due to its volatile nature, Se is difficult to analyze and needs specific caution when instrumentally chemical digestive analysis method is used. Therefore, the suitable database of Se for Korean foods is rarely observed. In this study, we analyzed the association of blood 25(OH) vitamin D level of 2008–2011 KNHANES datasets with dietary Se intake calculated using the food Se contents analyzed by INAA method. INAA is non‐destructive method which is no digestive method. The elderly with age over 60 year and participated in all the measurements of DXA, nutrition survey, and blood analysis were chosen. The dietary intake measured by 24‐hour recall method from nutrition dataset were used to calculate the selenium intakes of elderly. The food Se contents were coded using the KNHANES food database and used to calculate the dietary intake of elderly participated in KNHANES survey. The statistical analysis was conducted using SAS program (ver. 9.4) and considering the complex clustered sampling. The age‐standardized prevalence of Se intake deficiency in elderly Koreans over age 60y have a range from 39% to 63%, depending on age and gender. The lowest Se ingestions were found in both gender of elderly who have the age‐adjusted and unadjusted 25(OH) vitamin D level under 10ng/ml (p<0.001). In conclusion, this study suggested that blood 25(OH) vitamin D level is associated with dietary Se intake in aged Korean.
