在骨骼的健康管理中，最重要的是如何度过骨量达到峰值的时期，即适当的骨骼健康自我管理。因此，我们通过数字图像处理方法（DIP）评估了身体特征和饮食习惯对197名健康青春期女孩（日本初中生，12-15岁）第二掌骨骨矿物质密度（BMD）（sigma GS/D：BMD）的影响，这是身体和骨骼生长的重要时期。从各年龄组受试者的身体特征来看，各年龄组的身高均高于日本人的年龄标准值，但14岁和15岁组的体重显着低于日本人的标准值。与日本人按年龄划分的标准BMD值相比，受试者中12岁、13岁和14岁组的BMD较高，而15岁组的BMD较低（-7.3%）。从营养状况来看，各年龄段的能量、钙（Ca）和铁的摄入量均不足。根据富含钙食物的摄入频率来评估相对于日本人标准BMD值（标准值视为0%）的BMD。相对BMD值(%)随着富含钙食物的摄入频率的增加而增加。这些结果表明，保持适当的体格和摄入充足的钙等营养物质对于青春期骨骼生长很重要。积极推进主要针对饮食对青少年骨骼健康影响的教育指导是必要的。
In the health management of bone, of most importance is how to spend the period until peak bone mass, that is appropriate self management for bone health. Therefore, we evaluated the effects of physical characteristics and dietary habits on the bone mineral density (BMD) of the second metacarpal bone (sigma GS/D: BMD) by the digital image processing method (DIP) in 197 healthy adolescent girls (Japanese students at a junior high school, aged 12-15 y), an important period of physical and bone growth. Concerning the physical characteristics of the subjects according to age group, body height in each age group was higher than the standard values for Japanese according to age, but body weights in the 14-year-old and 15-year-old groups were significantly lower than the standard values for Japanese. Compared with the standard BMD values for Japanese according to age, BMD in the subjects was high in the 12-year-old, 13-year-old and 14-year-old groups but low in the 15-year-old group (-7.3%). Concerning the nutritional state, energy, calcium (Ca), and iron intakes were insufficient in every age group. BMD relative to the standard BMD value for Japanese (standard value was regarded as 0%) was evaluated according to the ingestion frequency of Ca-rich foods. The relative BMD value (%) increased with the ingestion frequency of Ca-rich foods. These results suggest that maintenance of an appropriate physique and adequate intake of nutrients such as Ca are important for bone growth during adolescence. Active promotion of educational guidance mainly on the effects of diet on bone health in adolescents in necessary.
