Riboflavin, Ascorbin Acid & Vitamin D status of 74 elderly Korean (35 men and 39 women)from urban households in Incheon were evaluated by blood analysis. Mean EGR-AC value of men was 1.05 while that of women was 1.03. Marginal deficiency of riboflavin(EGR-AC 1.15-1.35) was shown in 33.3% of men and 20% of women. Average plasma ascorbic acid contents of subjects were very low and men had significantly lower amount than women(0.23mg/㎗ vs 0.44mg/㎗). The percentages of subjects who had plasma ascorbic acid less than 0.4mg/㎗ were 88.9% of men and 45% of women. Mena serum Calcium, Inorganic phosphate contents and mean serum ALP activity of men were 9.97mg/㎗, 3.28mg/㎗ and 61.85 Unit/L respectively and those of women were 9.78mg/㎗, 3.49mg/㎗ and 67.80Unit/L respectively.
