| Outline of Final Research Achievements |
The bone mass and lifestyle of Japanese growing children were investigated longitudinally. The aim of study was to search for the promotion factors of bone growth in children. The bone area ratio of the right calcaneus was evaluated by quantitative ultrasound. Multiple regression analysis demonstrated that calcium and copper were positive influential factors of bone growth for males. For females, vitamin C and BMI were positive influential factors of bone growth.
We also examined the effect of School Lunch on bone between elementary school children attending schools that do not enforce School Lunch (the box-lunch group), in which children bring box lunches from home, and those that enforce School Lunch (the school-lunch group).The study subjects were fourth grade students. The bone area ratios of children in the school-lunch group were higher than those of children in the box-lunch group. This tendency did not change even after adjustment for the confounding factors.
