Height growth between four weeks and 20 years of 45 boys and 45 girls from the Zürich Longitudinal Growth Study (1955-1976) was analysed using kernel estimates. Timings of the mid-growth spurt (MS) and of the pubertal spurt (PS) were determined in an automatic way from the individual acceleration curves, together with height, percentage of height, velocity and acceleration at these ages. The small mid-growth spurt is a consistent phenomenon, peaking at 6.4 years (M,F) in acceleration and at 7.7 years (M) and 7.5 years (F) in velocity. There are no significant sex differences in its intensity. In girls, the PS follows in close succession to the MS; in boys there is a substantial period in between. In addition to the age of peak height velocity, ages of onset, maximal acceleration and end of the PS are defined. Sex differences in timing and size of the pubertal peak previously established were again verified. New results relate to the asymmetry of the PS, which is more pronounced in girls, and to sex differences in intensity and duration of the first rising phase of the PS. After this phase, boys and girls do not differ in timing but only in the intensity of deceleration.
利用核估计分析了来自苏黎世纵向生长研究（1955 - 1976年）的45名男孩和45名女孩在4周龄至20岁之间的身高增长情况。从个体加速度曲线中自动确定了生长中期突增（MS）和青春期突增（PS）的时间点，以及这些年龄时的身高、身高百分比、速度和加速度。小生长中期突增是一种持续存在的现象，加速度在6.4岁（男、女）时达到峰值，速度在7.7岁（男）和7.5岁（女）时达到峰值。其强度不存在显著的性别差异。在女孩中，青春期突增紧跟在生长中期突增之后；在男孩中，两者之间有一段相当长的时间间隔。除了身高速度峰值年龄外，还定义了青春期突增的开始年龄、最大加速度和结束年龄。先前确定的青春期峰值在时间和大小上的性别差异再次得到验证。新的结果涉及青春期突增的不对称性，这在女孩中更为明显，以及青春期突增第一个上升阶段在强度和持续时间上的性别差异。在这个阶段之后，男孩和女孩在时间上没有差异，只是在减速强度上有所不同。
