西安市儿童的骨龄和青春生长突增期间关系的研究

Relationship of the bone age and the pubertal growth spurt of the children in Xi'an

运用中国人骨成熟度标准——ＣＨＮ计分法计算骨龄值，以此估计儿童的生长发育水平。同时，使用作者开发的计算机骨龄评价系统，对西安市８～１６岁２８２例儿童的发育状况进行了调查，对发育正常者进一步研究了骨龄与青春生长突增期３个阶段间的定量关系。结果发现正常发育者占７４．１２％，提前发育者为１５．９６％，推迟发育者是９．９３％。并得出：男童骨龄从１２．１５岁、女童从９．５５岁进入加速期；男１３．７０岁、女１１．９０岁进入高峰期；男１６．０３岁、女１４．４０岁则到达减速期。这为正畸学的临床诊治提供了一个明确的参考指标。

The standards of estimating skeletal maturity of the hand and wrist for Chinese CHN scoring method were applied to assess the bone age of Chinese children. The growth of 282 Chinese children aged 8～16 years old in Xi'an was investigated using a computerized system. The relationship between bone age and pubertal growth spurt was studied in the average maturing subjects. 209 subjects (74.12%) were average maturing, 45(15.69%) were accelerated, 28(9.93%) were retarded. On the average, preceding peak growth began from the bone age of 12.15 years old in boys and 9.55 in girls, peak growth was at 13.70 and 11.90 years in boys and girls, slowing growth began at 16.03 in boys, 14.04 in girls, respectively. The data may be a reference for choosing the best time of treatment in orthodontics.
