本文对1980年17例意外骨折儿童的骨矿和钙状况进行了研究。这些儿童的年龄和性别与非骨折对照组相匹配。抽血检测血清Ca、P、Mg、25-羟基胆钙化醇（骨化二醇）、碱性磷酸酶和白蛋白。光子吸收法测定骨矿含量。两组之间的血清值无差异。在骨折组的17名儿童中，12名（71%）的BMC低于其匹配的对照组。骨折组骨矿含量低于对照组，为0.423 ± 0.001。0.042对0.461 ±。0.037克/厘米。在骨折组的15名患者中，4名患者的钙和磷摄入量低于推荐膳食供给量（RDA）的60%（800 mg/d），而所有对照组的钙和磷摄入量均至少为RDA的60%。骨折组中有4例钙、磷摄入量低于对照组，但BMC也低于对照组。
Bone mineral and Ca status of 17 children who suffered an accidental fracture in 1980 were studied. These children were matched by age and sex to a nonfractured control group. Blood was drawn for serum Ca, P, Mg, 25-hydroxycholecalciferol (calcidiol), alkaline phosphatase and albumin. Bone mineral content (BMC) was evaluated by photon absorptiometry. There were no differences in serum values between the 2 groups. Of the 17 children in the fracture group, 12 (71%) had a lower BMC than their matched controls. BMC of the fracture group was lower than their controls, 0.423 .+-. 0.042 vs. 0.461 .+-. 0.037 g/cm. Of the 15 in the fracture group, 4 ingested less than 60% of the recommended dietary allowance (RDA) for Ca and P (800 mg/day), while all the controls were ingesting at least 60% of the RDA. Four children of the fracture group who were ingesting less Ca and P than those of the control group also had low BMC.
