The influence of rate of skeletal maturation and midparent height on growth in height during adolescence was analyzed on longitudinal data for 184 boys and 166 girls from the Wrocław Growth Study. Seven biological parameters describing the shape of the growth curve in stature were derived from the Preece-Baines model 1 applied to individual serial data. Rate of skeletal maturation inferred from the difference between chronological and skeletal ages at 12 years in girls and 14 in boys. Principal components analysis of the biological parameters extracted three factors for boys and four for girls. The factors explained 90% and 97% of the total variance in boys and girls, respectively. The factors reflected attained size and the timing and intensity of the adolescent spurt in height. Multiple regression showed a high relationship between skeletal maturation rate, midparent height, and principal component scores. Three aspects of adolescent growth: size, timing, and intensity show an apparent sex difference. The timing and intensity of the spurt are highly affected by tempo of maturation in girls, but less so than in boys. It might suggest in girls a less efficient compensatory effect for reduced length of overall growth period in early maturers that increases height gain. Midparent height influences the size component during the spurt, thus adjusting the height parameters. The dependency between attained stature (height at take-off, PHV, and adult stature), timing, and initial intensity of the growth spurt of daughters and midparent height is greater than in sons.
基于弗罗茨瓦夫生长研究中184名男孩和166名女孩的纵向数据，分析了骨骼成熟速率和父母平均身高对青春期身高增长的影响。从应用于个体序列数据的普里斯 - 贝恩斯模型1中得出了七个描述身高生长曲线形状的生物学参数。根据女孩12岁和男孩14岁时的实足年龄与骨骼年龄之差推断骨骼成熟速率。对生物学参数进行主成分分析，提取出男孩的三个因子和女孩的四个因子。这些因子分别解释了男孩和女孩总方差的90%和97%。这些因子反映了已达到的身高大小以及青春期身高突增的时间和强度。多元回归表明，骨骼成熟速率、父母平均身高和主成分得分之间存在高度相关性。青春期生长的三个方面：大小、时间和强度存在明显的性别差异。身高突增的时间和强度在女孩中受成熟节奏的影响很大，但不如男孩明显。这可能表明，对于早熟女孩而言，其整体生长期缩短的补偿效应相对较低，这种补偿效应本可增加身高增长。父母平均身高影响身高突增期间的大小成分，从而调整身高参数。女儿的已达到身高（起始身高、身高突增高峰值和成人身高）、身高突增的时间和初始强度与父母平均身高之间的相关性大于儿子。
