Bone mineral content in the distal part of the forearm was measured in 301 normal children and adolescents aged from 7-20 years to estimate total body calcium in these age groups. From year 7 to 9 and from year 15 to 20 the mean values in boys were significantly higher than those in girls. In the lower age groups there was a slow increase in estimated total body calcium with age, followed by a sharp increase at the age of puberty.
对301名年龄在7至20岁的正常儿童和青少年测量了前臂远端的骨矿物质含量，以估算这些年龄组的全身钙含量。从7岁到9岁以及从15岁到20岁，男孩的平均值显著高于女孩。在较低年龄组中，估计的全身钙含量随年龄缓慢增加，随后在青春期急剧增加。
