中国成年人骨骼重量参考值

Reference values of skeleton mass for normal Chinese adults.

为编制中国参考人提供科学依据，收集了我国南北方地区成年人（２０～６０岁）４８６例的骨骼标本（男性４０９例女性７７例）。经实测全身１８类骨骼的干重量，引用国外已有的骨骼湿、干重比值，首次提出了我国成年人的骨骼总重量参考值，即男性８．０ｋｇ、女性５．４ｋｇ。此值不仅存在性别差异，也明显存在地区的差异。同时提出了我国成年人各类骨骼重量占骨总量的百分数和骨骼总重量占体重的百分数。由此，可根据个体实际体重直接推算骨骼总重量及各类骨骼的重量，具有实用价值。此外，根据ＩＣＲＰ参考人的骨骼源器官和靶器官的重量，又分别推得我国成年人的相应数值，这在辐射防护领域的骨剂量计算中具有重要的意义。

In order to provide scientific basis for compiling the data of a Reference Chinese Man, skeleton specimens from 486 adults (409 males and 77 females, 20-60 years old) from southern and northern regions of China were collected. By measuring the dry weights for all the eighteen kinds of bone and using the specific values of wet and dry bone weights from external information, the reference values of mass of total skeleton for Chinese adults (8.0 kg for males and 5.5 kg for females)were first proposed. There are apparent differences not only between males and females but also among various geographic locations. The relative weights of different kinds of bone as percentages of body weight for Chinese adults were suggested simultaneously. From this the mass of total skeleton and of different kinds of bone can be calculated directly according to the actual body weight of individuals. In addition, on the basis of the mass of source organs and target organs in bones from ICRP Reference Man, the relevant values for Chinese adults can be derived respectively. The data are most significant in the calculation of bone dose in the field of radiation protection.
