骨龄评定与预测身高骨龄是什么？青少年儿童在生长发育过程中，生长发育和成熟的进程不一定和他的生活年龄完全一致，即每个人都有两种年龄：生活年龄和生物年龄。

生活年龄：也叫日历年龄，是由出生年月日决定的，即每365天增加一岁。

生物年龄：是表示人的生长发育、成熟、衰老程度的标志。

在青少年儿童阶段，通常把生物年龄看成生长发育的程度。

发育程度（生物年龄）的评定，一般采用评定手腕骨骨龄的方法。

1987年起国家体育总局组织专家经过多年研究，制定了《中国人手腕骨发育标准CHN法》（简称《CHN法》）。

1992年被批准为中华人民共和国行业标准正式公布实施。

发育速度有时是不均匀的，一个人在365天内生物年龄不一定就是增加一岁。

有时增加一岁，有时会也增加一岁半甚至两岁多，有时又可能增加不足一岁。

进行发育评定时，习惯上将：生物年龄（骨龄）减生活年龄的差值在±1岁以内的称为发育正常。

生物年龄（骨龄）减生活年龄的差值>1岁的称为发育提前（简称：早熟）。

生物年龄（骨龄）减生活年龄的差值<－1岁的称为发育落后（简称：晚熟）。

例如：2001年4月5日出生的儿童，到2011年4月5日是整10岁，如果他的骨龄只有8.9岁，就评定为发育落后，如果他的骨龄为11.5岁就是发育提，前如果他的骨龄在9～11岁之间都是发育正常。

每一个人在生长发育过程中，受遗传、营养、体育锻炼、疾病等等因素的影响，发育的速度并不一定和日历年龄完全一致。

有的人发育提前，生物年龄会大于生活年龄。

也有的人生物年龄小于生活年龄。

但是，绝大多数人生物年龄与生活年龄是大体相符的。

1988年全国调查了2万多0~19岁青少年儿童。

平均差值仅为0.13岁。

在青少年儿童的生长发育阶段，评定他们的发育程度，对于促进青少年儿童健康成长，具有重要的意义。

预测身高：在青少年儿童阶段预测成年后的身高，除了对选拔运动员、挑选演员等有重要的意义外，在青少年体质评定中也有重要意义。

儿童骨龄及身高预测
骨龄是发育年龄的简称，它是以小儿骨骼实际发育程度同标准发育程度相比，所求得的一个发育年龄，它是确定骨成熟的指标。

骨龄是反映人体成熟程度的最有用指标，骨龄相对于实际年龄的提前或落后能决定儿童的生长未来，对成年的身高有重要影响。

一些全身性疾病、代谢性疾病、染色体异常等均有可能影响骨龄的变化。

所以要定期测定儿童的骨龄以了解其实际发育水平。

判断骨龄主要利用X线摄片。

一般以手腕部最为理想。

这里集中了大量的长骨、短骨和圆骨，集中反映了全身骨骼生长和成熟状况，而且投照方法简便，对人体的损害也最小。

判断骨骼钙化程度主要看三点：①骨化中心的数目和大小；②骨化中心和骨骺的形态变化；③骨骺和骨干的愈合情况。

利用骨龄推断的发育情况，从而反映身体生长发育的状态，有助于了解儿童身高发育的潜力。

另外，骨龄在矮身材疾病的诊断鉴别诊断和疗效观察中有着重要作用，也指导着医生怎样用药，如何治疗。

通过对儿童骨龄及目前身高的检测可以预测未来身高的趋势，有利于家长早期发现矮身材及代谢性疾病，尽早进行干预和治疗，从而提升最终身高。

骨龄评定与身高预测作者：王翠玲骨龄是什么？青少年儿童在生长发育过程中，生长发育和成熟的进程不一定和他的生活年龄完全一致，即每个人都有两种年龄：生活年龄和生物年龄。

生活年龄：也叫日历年龄，是由出生年月日决定的，即每365天增加一岁。

生物年龄：也就是骨龄，表示人的生长发育、成熟、衰老程度的标志。

根据X线片上长骨干骺端软骨板的宽度可判断儿童的生长潜力。

对于青春期生长和生理发育的研究发现，X光拍摄骨的形态变化（骨龄）可以成为反映生理年龄的一个极好的标志物。

每个化骨核骨化出现的时间、大小、形态及骨骺与干骺端愈合的时间是有规律的，人体骨骼的发育成熟遵循一定的规律，其与年龄的关系称骨龄（BA）。

由于营养不良、肥胖、内分泌疾患、骨发育障碍、代谢性疾病等均可使骨龄发育落后或加速，一般健康儿童的骨龄与实际年龄是一致的，因此骨龄是提示小儿青春期成熟度的简易而又可信的诊断及治疗监测指标。

目前国际上学者公认测定骨龄的方法是评估小儿生长发育度最好的方法。

骨龄评测：现在国内一般采用拍摄左手腕正位X光片来评价骨龄。

一个人一生中发育速度有时是不均匀的，一个人在365天内生物年龄不一定就是增加一岁。

有时增加一岁，有时会也增加一岁半甚至两岁多，有时又可能增加不足一岁。

进行发育评定时，习惯上将：生物年龄（骨龄）减生活年龄的差值在±1岁以内的称为发育正常。

生物年龄（骨龄）减生活年龄的差值>1岁的称为发育提前（简称：早熟）。

生物年龄（骨龄）减生活年龄的差值<－1岁的称为发育落后（简称：晚熟）。

例如：2001年4月5日出生的儿童，到2011年4月5日是整10岁，如果他的骨龄只有8.9岁，就评定为发育落后，如果他的骨龄为11.5岁就是发育提前，如果他的骨龄在9～11岁之间就是发育正常。
