摘 要:目的了解不同海拔地区藏族青少年骨龄发育状况,为评价藏族青少年生长发育状况提供科学依据。方法分层整群抽取西藏不同海拔高度地区12所中小学的2 232名青少年,采用CHN骨龄测定法对不同海拔地区居住的青少年骨龄发育状况进行调查,比较不同海拔地区藏族青少年骨龄发育差异。结果绝大多数年龄组青少年骨龄低于日历年龄。高海拔地区和低海拔地区男女不同年龄组骨龄比较显示,部分年龄组差异有统计学意义(P值均<0.01);高海拔地区和低海拔地区男、女群体及总人群的骨龄比较显示,高海拔地区骨龄高于低海拔地区,差异均有统计学意义(P值均<0.01)。结论不同海拔地区藏族青少年骨龄发育有差异,较高海拔地区高于低海拔地区。Objective By comparing the bone age among Tibetan adolescents and discussing the influence of attitude, to provide the scientific basis on evaluating Tibetan individual growth status. Methods A total of 2 232 adolescent from 12 middle schools and primary schools were selected from Naqu / higher altitude, elevation of 4500-4700 meters) and Lhasa ( lower altitude, elevation of 3 658 meters) through stratified cluster sampling method; CHN method was used to evaluate their bone age; Differ- ences were available between the higher altitude district and lower ahitude district. Results Average of skeletal age was smaller than chronological age in most ages; there were differences in part of ages( P〈0.01 ) ; the skeletal age in higher altitude district was bigger than lower altitude district ( P〈0.01 ). Conclusion There is different skeletal age in different elevation, the higher is bigger than the lower.
