Abstract
The present study was performed to assess nutritional status of thiamin in 104 elementary school children, living in rural areas of Chungbuk. Dietary intake was obtained by 24 hour recall method and blood was collected to analyze the transketolase activity in erythrocytes. Average dietary intake of thiamin was found to be adequate (1.l5mg, 109.2％ of RDA), even though dietary intake of energy was not more than 1,719kcal, 81.5％ of RDA. Transketolase activity in erythrocytes was distributed in the range of 0.294-0.744mU/mgHb and the mean value was 0.540mU/mgHb. The mean value of TPP effect was 7.9％ and the range was 0-77.4％. It appeared that 7.7％ of children were deficient in thiamin, severely or marginally. There were no significant correlations between transketolase activity and dietary thiamin intake, and between TPP effect and dietary thiamin intake. Mean DVS (Dietary variety score) of the children was 14.2${\pm}$3.2 and DVS was apparently correlated with thiamin intake.
