초록

The purpose of this study was to investigate the relationship between bone mineral density, and physical activities and nutrient intakes in female adolescents. The 5th Korean national health and nutrition examination survey were analyzed using SPSS 23.0 package program. Results showed that bone mineral density was positively correlated with age, weight, height, high intensity physical activity, total physical activity, and strength exercise days but negatively correlated with carbohydrate intake and protein intake per body weight. After adjustment of age, height and weight, high intensity physical activity positively affected bone mineral density in female adolescents. In addition, female student showed high bone mineral density when they participated more than 5 days of high intensity physical activity or 3 days of strength exercise. These results indicated that to maintain adequate bone mineral density, female adolescent should perform high intensity physical activities or strength exercise. Therefore, physical education teachers should help female students actively participate in physical education classes or school sports club.
