To evaluate antioxidant vitamin status in young women, serum retinol, α-tocopherol, and total ascorbic acid levels were determined in 284 female students aged 21〜22 years, and serum β-carotene in 162 females. Dietaory vitamin intakes were assessed by a 3-day food record immediately before the day of blood-collecting. The intakes of vitamin A, vitamin E and vitamin C in 50.0 %, 32.7 %, and 50.4 % of students had been fulfilled their RDAs, respectively. The 59 % of dietary vitamin A intakes were from β-carotene (n=162). The mean of energy intake was low (1581 ± 303 kcal). A significant correlation was observed for only β-carotene between serum level and dietary intaake. The 2.5〜97.5 % distribution ranges and mean ± SD of serum vitamin levels were obtained from the subjects with dietary vitamin intake above RDA:0.20〜0.72 (0.42 ± 0.12) mg/l for retinol, 6.1〜22,0 (12.2 ± 3.1) mg/l for α-tocopherol, 7.2〜16.8 (12.3 ± 2.1) mg/l for ascorbic acid. That of serum β-carotene was 0.13〜2.00 (0.67 ± 0.11) mg/l calculated from all the subjects.
