Abstract

This study was conducted to assess thiamin nutritional status in Korean female college students on normal diet Weighed food records and 24-hour urine samples were collected from subjects for three days. Mean daily intake of thiamin was calculated from food records. Pooled urine samples were analyzed for thiamin and creatinine. Mean daily intake of thiamin was 0.72$\pm$0.22mg, 72% of Korean RDA for the group. Thiamin intake per 1000kca1 was 0.4997$\pm$0.09mg, which is close to the RDA. Mean daily urinary excretion of thiamin were 130.11$\pm$ 71.06$\mu\textrm{g}$/24hr and 180.59$\pm$129.79$\mu\textrm{g}$/g creatinine. Mean daily thiamin intake(mg/day), but not thiamin intake per 1000kca1 was showed by positive correlated with urinary excretion of thiamin(p<0.01). Thiamin nutritional status of the subjects based on 24-hour urinary excretion of thiamin was deficient in one subject(19%), low in nineteen subjects(36.5%), and acceptable in thirty two subjects(61.5%). Only six subjects were in low thiamin status based on thiamin excretion per gram creatinine. Therefore, total urinary excretion of thiamin seems to be more sensitive to marginal thiamin deficiency compared to urinary excretion per gram creatinine. From the results of the study, the prevalence of marginal thiamin deficiency seems to be high among young Korean adult women.
