河南与浙江地区汉族女性青少年骨发育差异性分析

The Analysis of Variation of Han Female Adolescent Bone Development in Henan and Zhejiang Province

目的探讨河南与浙江地区之间女性青少年骨发育的差异性。方法摄取河南及浙江两地599例年龄介于12～19岁的女性锁骨胸骨端及六大关节X线片。对照青少年骨发育分级标准24项骨骼发育指标进行阅片,并通过数学模型法计算骨龄,然后利用SPSS15.0软件对骨龄与生活年龄的比值进行不同地区间差异性分析。结果河南女性青少年骨发育在14～15岁年龄段(不含15周岁)比浙江提前约0.39岁,河南女性青少年骨发育在15～16岁年龄段(不含16周岁)比浙江滞后约0.37岁,河南女性青少年骨发育在18～19岁年龄段(不含19周岁)比浙江滞后约0.38岁,余年龄段无统计学差异。结论河南与浙江地区女性青少年骨发育比较存在差异性,呈现先快后慢的趋势。本研究结论可供法医学、人类学、临床医学等有关学科对青少年骨龄评价作为参考。

Objective To study the difference of Han female adolescent bone development in Henan and Zhejiang province. Methods All radiography including sternal end of clavicle and six main bone joints were taken from 599 female adolescents with age between 12 to 19 in Henan and Zhejiang province. Twenty four skeletal development indexes were analyzed based on ＂The Grading Standards＂ of skeletal growth of teenagers and then the bone age were calculated using mathematical model functions. The ratios of the bone age and the chronological age were analyzed by statistical software. Results The development of Henan female adolescents＇ skeleton was about 0.39 years earlier than that in Zhejiang at the age of 14-15 years old. The development of Henan female adolescents＇ skeleton was about 0.37 years later than that in Zhejiang at the age of 15-16 years old. The development of Henan female adolescents＇ skeleton was about 0.38 years later than that in Zhejiang at the age of 18-19 years old. There was no statistics significance in other age group. Conclusion The female adolescent bone development in Henan province is faster at earlier stage and then slower than that in Zhejiang province. The results provide potential value for the forensic medicine, anthropology and clinical medicine.
