【摘要】：目的比较以不同骨龄标准所评价的青少年手腕骨骨龄与生活年龄的差异,观察生长发育长期变化对青少年年龄推测的影响。方法从中国5座大中城市抽取11464名(男5873,女5591)3~18岁汉族正常青少年儿童,并另随机抽取950名(男516,女434)12~18岁骨发育正常的汉族青少年作为验证样本。按CHN法和RC法骨龄标准评价手腕部X线片骨龄,并对不同方法评价的骨龄及生活年龄进行统计学分析。结果各年龄组CHN法骨龄中位数大于RC骨龄,其差异具有显著性意义(P0.05)。验证样本中,在男12~16.5岁、女12~14.5岁之间,CHN骨龄减生活年龄之差值分别为0.35~1.00岁和0.57~1.16岁(P0.01);RC骨龄减生活年龄的差值分别为-0.26~0.23岁和-0.27~0.06岁(P0.05)。在男17~18岁、女15~17岁之间,CHN骨龄减生活年龄的差值分别为-0.52~-1.05岁和-0.16~-1.13岁(P0.05),RC骨龄减生活年龄的差值分别为-0.35~-0.48岁和-0.22~-0.79岁(P0.05)。结论CHN法骨龄高于生活年龄,在大部分年龄组RC骨龄与生活年龄基本一致。
[Abstract]:Objective to compare the differences of wrist bone age and life age in adolescents with different bone ages, and to observe the effect of long-term changes of growth and development on juvenile age speculation. Methods 11464 normal children (male 5873, female 5591) of Han nationality aged 18 years were selected from 5 large and medium cities in China, and another 950 Han nationality adolescents (male 516, female 434) with normal bone development were randomly selected as a test sample. The bone age of wrist radiographs was evaluated according to the bone age criteria of CHN method and RC method, and the bone age and life age of different methods were analyzed statistically. Results the median bone age of CHN was higher than that of RC in all age groups (P0.05). In the tested samples, the difference of bone age and life age of CHN was 0.35 / 1. 00 years old and 0. 57 ~ 1. 16 years old respectively (P0.01) in male (12 / 12) and female (12 / 14. 5) years old (P < 0. 01). The difference between bone age and life age of RC was -0.26 ~ 0.23 years old and -0.27 ~ 0.06 years old respectively (P0.05). The difference between the bone age of CHN and the age of life was -0.52 ~ 1.05 years old and -0.16 ~ 1.13 years old (P0.05), respectively, when the male was 18 years old and the female was 15 ~ 17 years old (P0.05), and the difference was -0.52 ~ 1.05 years old and -0.16 ~ 1.13 years old, respectively. The difference between bone age and life age of RC was -0.35 ~ 0.48 years old and -0.22 ~ 0.79 years old respectively (P0.05). Conclusion the bone age of CHN method is higher than that of life age, and the bone age of RC is basically the same as that of life age in most age groups.
