ABSTRACT
Nutritional factors affecting bone mineral density (BMD) in the different age groups of Korean men were investigated to obtain baseline data for maintaining bone health. Information on diet and anthropometry was collected in 80 elementary school children, 83 high school students, 87 adults aged 25 to 35 years and 98 elderly people over 60 years of age. Data for food and nutrient intake were obtained by 24-hour recall method. BMDs of lumbar spine (L(2) - L(4)) and femoral neck were measured by dual energy x-ray absorptiometry. The relationship between BMD and nutritional factors were analyzed. In the femoral neck, 5.7% of adults was classified as osteopenia and 47.9% and 37.8% of the elderly were classified as osteopenia and osteoporosis. It was shown that plant protein, Ca, P, Fe, thiamin, riboflavin and vitamin C intakes were related with BMD in all age groups. As for the mean adequacy ratio (MAR) of nutrients, the lowest quartile group of BMD showed significantly lower MAR among children. The RDA percent of nutrients was a strong influential factor on BMD. Subjects who consumed below 75% of Korean RDA in energy, vitamin A, thiamin, and vitamin C showed lower BMD. Stepwise multiple regression analysis revealed that MAR in children, vegetable Ca in adolescents, and vitamin C in adults and elderly people were the highest influential factor on BMD. Therefore, the above results demonstrated that not only calcium but also other nutrients such as protein, iron, vitamin A, riboflavin, and vitamin C were necessary in order to keep the healthy bone status. In addition, although there were various dietary factors that influenced bone density, MAR was identified as the major factor that affected bone density. Thus, a balanced diet that includes all nutrients is necessary for a healthy bone density.
