To assess the nutrient intakes and diet quality of middle school students living in Kangneung area, a dietary survey using the 3-day food record was conducted with 226 subjects. Mean daily energy intake was 2114±502 kcal with 61.6% of energy supplied by carbohydrate, 16.4% by protein and 22.0% by fat. As well as insufficiencies in calcium and iron intakes, the bioavailability of calcium and iron consumed is considered to low because most of them came from plant origins. For calcium, iron, vitamin A, and vitamin B2, the proportions of subjects with intake levels less than 75% of RDA were all over 46%. The mean adequacy ratio (MAR), an index of overall dietary was 0.70 for males and 0.73 for females. The indexes of nutritional quality (INQ) were over 1 for most nutrients except 4 nutrients; 0.48 of calcium, 0.64 of iron, 0.73 of vitamin A, and 0.79 of vitamin B2. Nutrient intake levels less than 75% of RDA may be appropriate as a criteria for insufficiency of nutrient intakes. Based on these results, it is evident that some of middle school students in Kangneung area did not consume enough nutrients, especially calcium, iron and vitamin A.
