Adolescence in the period requiring the largest amount of nutrients including calcium during their whole lifetime. This study was conducted to provide the direction for nutritional education to increase calcium consumption for the teenagers. We conducted a survey of 135 male students and 144 female student from 3 middle schools in Daegu. Results indicated that male students showed significantly higher intake frequency of calcium source foods(p<0.01) and higher recognition for milk and dairy products(p<0.05). When students were grouped into higher group and lower group based on the recognition for milk and dairy products, significantly higher habitual calcium intake level was observed for higher recognition group(p<0.001). According to behavior change level, students in the action phase showed higher recognition for milk and dairy products than groups(p<0.001). Thus, we concluded that it is necessary to provide reinforced nutrition education, especially for female students, with focuses on the promotion of milk and dairy products and recognition and increasing awareness of necessity for milk and dairy products intake in order to promote calcium consumption.
