摘要

该研究涉及到幼儿期和幼儿期性别躯体差异水平和载体的形成过程,3-6岁性别二态性与成人性别二态性的特殊特点,主要人体测量尺寸(身高、体重、胸围)性别二态性动态的种族异质性;考虑年龄特征的数据分析的最适当的算法。对20世纪50年代至2010年代俄罗斯和前苏联儿童的大量资料(超过200个样本)进行概括,可以描述性别体细胞二态性在群体间分布的令人信服的一致性;各维度的两性二态性标准化水平与各维度本身的平均人口值之间的显著相关性的性别差异矢量-男孩为正,女孩为负,这可能被解释为确认两性的躯体变异对性别差异形成的贡献。当局部分析数据时,在更大的范围内,性别二态性允许估计体细胞生长动力学的种族间特异性。特别是,俄罗斯儿童生长动态的明确性别同步性,无论其早期和第一童年的发展生态位如何;不同种族的一些群体也有类似的同步性。为了确定已知的年龄生理效应,在半生长突增前生长活性下降,这在种群间是不同的,在同质群体的情况下。因此,研究结果表明,身体尺寸性别二态性的敏感性可以作为早期和幼儿期身体状态和生长动态的民族-地域多样性的信息指标。

Ethnic variability of growth processes through the prism of sexual dimorphism of body dimensions (based on data of early and first childhood children)
The study deals with the process of forming of the level and vector of sex somatic differences through early and first childhood, specific peculiarities of sexual dimorphism at 3–6 years of age as compared to the sexual dimorphism of adults, ethnic heterogeneity of sexual dimorphism dynamics of main anthropometric dimensions (height, weight, chest girth); most adequate algorithms of analysis of data considering age peculiarities. Generali-zation of vast material on children of Russia and former USSR of 1950s–2010s (over 200 samples) allowed to describe convincing conformities of intergroup distribution of sex somatic dimorphism; different by sex vector of significant correlations of standardized levels of sexual dimorphism of dimensions with average population values of dimensions themselves — positive for boys , negative for girls, which may be interpreted as confirmation of the contribution of somatic variability of both sexes to forming of sexual differences. When analyzed of data locally, under greater enlargement, sexual dimorphism allowed to estimate inter-ethnic specificity of somatic growth dy-namics. In particular, definite sex synchrony of growth dynamics of Russian children regardless of the ecological niche of development through early and first childhood; similar synchrony for some groups of different ethnicity. To fix well known in age physiology effect of decreasing of growth activity before semigrowth spurt, which chrono-logical age differs between populations, for the case of more homogeneous groups. Thus, the results show the sensitivity of sexual dimorphism of body dimensions as the informative indicator of ethno-territorial diversity of somatic status and growth dynamics through early and first childhood.
