Abstract

The purposes of this study are to evaluate nutritional status and dietary intake of vitamin A in 5th and 6th grade primary school children in Chungbuk. Also the relationships between nutritional status and factors relevant to dietary intake of vitamin A were examined. For the study, total 180 children in urban area of Chongju city(37 boys and 40 girls) and rural area of Eumsong gun(56 boys and 47 girls) were recruited. For the assessment of dietary nutrients intake including vitamin A, 1-day, 24-hr recall method was applied. And serum retinol contents were analyzed by HPLC to diagnose the nutritional status of vitamin A. The average of daily vitamin A intake was 490R.E., 81.8% of RDA. Vitamin A intake of urban was higher than that of rural children(p < 0.001). Of the total dietary vitamin A intake, only 25.8% came from animal retinol, means that children still heavily depend on plant carotenoids as vitamin A floods. The average serum retinol concentration of total 180 children was 37.2$\mu\textrm{g}$/100ml. Serum retinol concentration of urban children was 37.3$\mu\textrm{g}$/100m1, significantly higher than rural children of 35.6$\mu\textrm{g}$/100m1(p < 0.05). According to the biochemical criteria, no one was in critical vitamin A nutritional status. Because of relatively large day-to-day vitamin A intake, 1-day, 24-hr recall method may not be the proper way to assess the usual intake of vitamin A. In conclusion , to diagnose the nutritional status of vitamin A by dietary survey, it is necessary to develop new survey technique which measure the dietary habit of the people.
