| 目的 通过对比G-P图谱法、CHN法和中华05计分法在青少年乒乓球运动员中的应用，了解3种骨龄评价方法各自的特点，为青少年体育比赛和运动员选材提供参考依据。方法 选取参加2016年全国少儿乒乓球杯赛的运动员本人的手腕部后前位数字X光片202例,分成男未进人青春期组、女未进人青春期组、男进人青春期组和女进人青春期组四组，分别使用 G-P图谱法、CHN法和中华05计分法判读各组骨龄，单因素方差分析比较3种方法的差异性，相关分析比较3种骨龄结果与 年龄的相似程度，EXCEL统计骨龄超过生活年龄1岁以上的例数。结果 ①在女进人青春期组中，G-P图谱法、CHN法和中华05计分法具有非常显著性差异,其中，中华05骨龄与年龄的相关系数最高，G-P骨龄次之，CHN较低。②G-P骨龄、CHN骨龄和中华05骨龄超过生活年龄1岁以上的例数分别为43例、52例和16例，三种骨龄结果均超过生活年龄1岁以上的例数为 11例。结论 ①对于进人青春期的乒乓球女子运动员，需要测骨龄时，建议使用中华05计分法。②对于儿童青少年体育比赛,建议使用中华05计分法评价骨龄，可以有效减少骨龄超龄的假阳性率。 |

| Objective To compare bone age assessment methods of Greulich-Pyle, CHN and and to provide reference data for future application. Methods X-ray films were obtained in participated in the National Children’ s table tennis match. They were divided into 4 groups：puberty group, male puberty group and female puberty group. We used repeated-measures differences among the 3 methods, used correlation coefficients to analyze the relationship between chronological age and each of the 3 methods, and used EXCEL to analyze the status of difference with chronological age for more than one year. Result ①In the female puberty group, statistically significant difference was identified among Greulich-Pyle method, CHN method and CHN05 method.② For forwarding chronological age for 1 year and more, there were 43, 52 andl6 cases according to Greulich-Pyle method, CHN method, and CHN05 method, respectively. Conclusion ①In puberty girls, CHN05 skeletal age score method is recommended for bone age measurement. ②In the table tennis youth sports competition，using Greulich-Pyle method and CHN skeletal age score method tend to estimate bone age forward, therefore it is necessary to use CHN05 skeletal age score method to reduce the false positive rate of bone age in youth table tennis athletes. |
