海南、河南及浙江地区汉族男性青少年骨发育差异性分析

Analysis of Variation of Han Male Adolescent Bone Development in Hainan,Henan and Zhejiang Provinces

目的探讨海南、河南、浙江地区之间汉族男性青少年骨发育的差异性。方法收集海南、河南及浙江3地877例12.00～20.00周岁汉族男性青少年锁骨胸骨端、骨盆及肢体六大关节X线片。依据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,利用SPSS 11.5软件对骨龄与生活年龄比值进行差异性分析。结果在12.00～12.99岁年龄段海南男性青少年骨发育比河南、浙江分别提前1.09岁、1.26岁;在13.00～13.99岁年龄段海南男性青少年骨发育比河南、浙江分别提前0.70岁、1.38岁,且此年龄段河南男性青少年骨发育比浙江提前0.68岁;在18.00～18.99岁年龄段海南男性青少年骨发育比河南滞后0.79岁;在19.00～20.00岁年龄段海南男性青少年骨发育比河南、浙江分别滞后0.70岁、0.95岁。结论海南、河南、浙江男性青少年骨骼发育存在明显差异。本研究结果可为法医学、人类学及临床医学等相关学科在进行骨龄评价时提供参考。

Objective To study the difference of bone development of the Han male adolescents in Hainan,Henan and Zhejiang provinces.Methods All radiographs including sternal end of clavicle,pelvis and six main bone joints taken from 877 Han male adolescents aged between 12.00 and 20.00 in Hainan,Henan and Zhejiang provinces were reviewed.Twenty-four indices of skeletal development 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 then analyzed by statistical software.Results The development of Hainan male adolescents＇ skeleton were about 1.09 years and 1.26 years earlier than that in Henan and Zhejiang at the age group of 12.00-12.99 years.The development of Hainan male adolescents＇ skeleton were about 0.70 years and 1.38 years earlier than that in Henan and Zhejiang at the age group of 13.00-13.99 years,while the development of Henan male adolescents＇ skeleton were about 0.68 years earlier than that in Zhejiang in this age group.The development of Hainan male adolescents＇ skeleton were about 0.79 years later than that in Henan at the age group of 18.00-18.99 years.The development of Hainan male adolescents＇ skeleton were about 0.70 years and 0.95 years later than that in Henan and Zhejiang at the age group of 19.00-20.00 years.Conclusion There are significant differences in the skeleton development of Han male adolescents between the provinces of Hainan,Henan and Zhejiang.These results provide potential value for the practice of forensic medicine,anthropology and clinical medicine.
