目的深入探讨青春期儿童身高生长突增规律。方法于1991－1999年对沈阳市秦山小学两个班级121名健康儿童（男58人，女6人）进行生长发育的追踪观察。结果沈阳市女孩生长突增开始年龄为（9．17±0．95）岁，突增开始速度为（4．80±1．01）Cm／y，突增高峰年龄为（11．51±1．00）岁，突增高峰速度为（11．42±2．30）cm／y。结论不同成熟类型女孩身高突增起始年龄。停止年龄与高峰年龄存在一致性，早熟型突增起始速度大于晚熟型，早熟型加速期突增时间和幅度明显小于一般型和晚熟型，而减速期交增时间和幅度明显大于一般型和晚熟型。其他指标差异均无显著性（P＞0．05）。
Objective To explore in depth the law of sudden growth of adolescent height growth. Methods From 1991 to 1999, 121 healthy children (58 males and 6 females) in two classes of Shenyang Qinshan Primary School were followed up. Results The onset of sudden onset of growth in girls was (9.17 ± 0.95) years old in Shenyang. The onset of sudden onset was (4.80 ± 1.01) cm / y and the peak age of sudden increase was (11.51 ± 1) .00) years old, the sudden increase peak speed was (11.42 ± 2.30) cm / y. Conclusion The onset age of sudden onset of height in different mature type girls. There was consistency between the stopping age and the peak age. The onset speed of early maturity type was greater than that of late maturity type. The time and amplitude of the sudden increase of early maturity type was obviously less than that of general type and late maturity type. Late maturity type. There was no significant difference in other indexes (P> 0.05).
