The purpose of this study was to identify calcium intake and cognition on calcium of adolescents in Busan area. Questionnaires including dietary habit, cognition on calcium, preference of calcium rich foods and diet record were developed. The questionnaires surveyed 285 adolescents consisted of 145 6th grade students (younger adolescents group, male: 72, female: 73) and 140 11th grade students (older adolescents group, male: 66, female: 74). Adolescents appeared high cognition for function of calcium and milk but low cognition for nutrients related to absorption of calcium. Younger boy adolescents among them appeared the lowest score of cognition on calcium. The most preferred calcium rich foods in adolescents were ice-cream, laver and then yogurt whereas soybean and icefish dried appeared the lowest preference. Calcium intake of adolescents was 491.5~530.5 mg, 61.4~ 66.3% of RDA for Koreans, in female and 554.5~636.7 mg, 69.3~70.7% of RDA for Koreans, in male. 64.9% of older girl adolescents showed calcium intakes under 66.7% of RDA for Koreans and this group also appeared less frequency of exercise than other group. Calcium intake of adolescents consisted of 44.6~53.3% from animal foods and 42.4~51.4% from plant foods. The adolescents consumed milk and milk products most, then vegetables and fishes as calcium source foods. Correlation analysis indicated that calcium intake was positively related to cognition on calcium of adolescents.
