作为对 212 名随机选择的瑞典城市儿童生长发育的前瞻性研究的一部分，收集了青少年身高生长、女孩初潮发生和男孩声音变化的纵向数据。青春期生长突增的起始峰值和结束是在未平滑的身高增量曲线上定义的。研究了这些事件与初潮和声音变化之间的时间关系。初潮发生在 10.7-16.1 岁之间（平均 13.1 岁，SD = 1.09）。在身高峰值速度之前没有发生月经出血，并且所有女孩在突增结束之前都有初潮。临床评估的声音变化开始于 11.5-16.5 岁（平均 13.9 岁 SD = 1.03）。在 12.5-17.5 岁之间观察到具有成人特征的声音（平均 15.0 岁，SD = 0.98）。声音变化的持续时间在 < 1 年和 > 3 年之间变化。当男孩开始变声时，正处于生长高峰期。当声音获得成人特征时，生长速度就开始减慢。
Longitudinal data on adolescent growth in body height and on the occurrence of menarche in girls and voice change in boys were collected as part of a prospective study of the growth and development of 212 randomly selected Swedish urban children. The onset peak and end of the pubertal growth spurt was defined on the unsmoothed incremental curve of height. The relationship in time between these events and menarche and voice changes was studied. Menarche occurred between 10.7-16.1 yr (mean 13.1 yr, SD = 1.09). No menstrual bleeding occurred before peak height velocity and all girls had menarche before the end of the spurt. Clinically assessed voice change began between 11.5-16.5 yr (mean 13.9 yr SD = 1.03). A voice with adult characteristics was observed between 12.5-17.5 yr (mean 15.0 yr, SD = 0.98). The duration of the voice change varied between < 1 yr and > 3 yr. When the voice change of a boy has begun, the growth spurt is in its most intensive phase. When the voice has acquired adult characteristics, the growth rate has begun to decelerate.
