根据中国汉族女性甲状软骨推算年龄的研究

Age determinaton by radiographic feature of thyroid cartilage in female han population

目的 根据中国汉族女性甲状软骨推算年龄。方法 对69例已知年龄的中国汉族女性甲状软骨进行软X线摄片和(或)普通X线摄片,从甲状软骨的摄片上选择5个与年龄变化关系较为密切的观察部位,每个部位又划分成3至6个等级,然后采用多元线性回归分析法,建立其推算年龄的数学模型。结果运用该方法推算女性甲状软骨年龄,其标准差为1.969,复相关系数为0.984。结论 本方法适用于中国汉族女性甲状软骨年龄推算,其有效年龄范围为18～60岁。

Objective To seek a method of age determination. Methods This sample consists of 69 female Chinese han individuals whose ages been known. Five positions were selected from their radiograms which have been divided into three or six grade and then set up a mathematical model to deduce age by multiple linear regression analysis. Results The standard deviation of female thyroid cartilage is 1.969 and the multiple correctation coefficient is 0.984. Concousion The observation proved that age determination by radio-graphic feature of thyroid cartilage can be used for female Chinese han population from 18 to 60 years old.
