项目摘要

The timings of the adolescent growth spurts were analyzed on the chronological and the biological (TW2 RUS skeletal maturity) time scales to clarify the change to body proportion with growth. The items analyzed were weight, height, sitting height, leg length, arm length, shoulder width and hip width. The subjects consisted of 9,209 schoolchildren from Ogi Growth Study between 1979 and 1988. Median single-year velocities were smoothed by a cubic spline function with AIC estimation. The multivariate allometry also applied to the date. The peak ages and the RUS scores at the adolescent growth spurt for the measurements were estimated from the growth velocity curves.The peak for boys appeared between the ages of 12.7 and 13.3 years in sequent order as hip width < leg length < arm length < height < sitting height shoulder width < weight. The peak for girls appeared between the ages of 9.9 and 11.4 years in sequent order as leg length < arm length < shoulder width < height < sitting height < hip width < weight. This suggested the caudocephalic growth gradient during boys' shape formation.When the timings for the peak at adolescent growth spurt were analyzed on a biological time scale, no discrepancies between the measurements were found. The peaks were centered around the TW2 RUS scores between 550 and 560 points for boys, between 670 and 680 points for girls. The shape changes of the body occurred almost of simultaneously.The Multivariate allometric analysis revealed the allometric but not isometric relation to the growth of total body. In boys leg and arm lengths and shoulder width showed positive allometry and hip width and sitting height showed negative allometry. In girls the hip width and arm length showed positive allometry ; leg length did isometry ; and shoulder width and sitting height did negative allometry with increase of total body size.

在时间和生物（TW 2罗斯骨骼成熟度）时间尺度上分析青少年生长突增的时间，以阐明身体比例随生长的变化。分析的项目包括体重、身高、坐高、腿长、臂长、肩宽和臀宽。研究对象包括1979年至1988年Ogi生长研究的9，209名学童。用三次样条函数和AIC估计平滑了单年平均流速。多元异速生长也适用于日期。根据生长速度曲线推算出青春期生长突增期的峰值年龄和罗斯评分，男孩的峰值年龄在12.7 ~ 13.3岁，依次为臀宽<腿长<臂长<身高<坐高<肩宽<体重。女生身高峰值出现在9.9 ~ 11.4岁，其大小顺序为：腿长<臂长<肩宽<身高<坐高<臀宽<体重。当用生物时间尺度分析青春期生长突增的峰值时间时，没有发现测量值之间的差异，峰值集中在TW 2罗斯分数550 - 560分之间，男孩在670 - 680分之间。多变量异速生长分析表明，个体的生长与个体的生长呈异速生长关系，而非等长生长关系。男孩的腿长、臂长和肩宽呈正异速生长，而臀宽和坐高呈负异速生长。女生的臀宽和臂长随身高的增加呈正异速生长，腿长随身高的增加呈等速生长，肩宽和坐高随身高的增加呈负异速生长。
