“…As the authors point out in their analysis, for the adult populations, the literature shows gender-differentiated phenotypic plasticity of a significant level, in particular, disproportionately high plasticity of fat deposition in the female sex and disproportionately high plasticity of lean mass in the male [Wells, 2012]. The picture for samples of definitive age and for infants in this study is not identical, however, the fact of different ecosensitivity by gender is confirmed at the start of postnatal ontogenesis [Gorbacheva, Fedotova, 2022b].…”

“…It is also shown that the ethnic factor makes a significant contribution to the formation of the intergroup diversity of growth processes and sexual dimorphism patterns in infancy. Different ethnic groups in the same anthropoecological niche have both an unequal level of sexual dimorphism of each of the body sizes, and some ethno-specific features of the age dynamics of sexual dimorphism [Gorbacheva, Fedotova, 2022а]. To a certain extent, the variability of sexual dimorphism of the main body sizes also depends on the level of urbanization of the region of residence.…”

“…The nonlinearity of the dynamics of its level for the studied body sizes during the first year of life is confirmed. The most significant quantitative indicator of secular processes, obtained on the materials of several series of data from infants in Moscow, is sexual dimorphism in body height [Gorbacheva, Fedotova, 2022с].…”

Introduction. The present study is of a complex nature and is devoted to the assessment of the main directions of the development of auxology in Russian anthropology. To a large extent, this work is a continuation of the review of the activities of the laboratory of auxology of the Anuchin Research Institute and the Museum of Anthropology of Moscow State University [Godina, 2010]. At the same time, the main directions of work are considered and described in more detail not only directly by the auxology laboratory, but also by other working groups of the same Institute, the Department of Anthropology of the Faculty of Biology of Lomonosov Moscow State University, as well as other academic institutions. Materials and methods. Specifically, in this part of the work, articles devoted to the comprehensive assessment of the processes of growth and development of children from birth to 3 years old, which were published in the «Moscow University Anthropology Bulletin» from 2009 to 2022, were used as a source of information. Results and discussion. The studies conducted in this area affect a large number of aspects of physical development in infancy and early childhood – for example, factors influencing these processes (evolutionary, climatic, geographical, ethnic and genetic factors, constitutional features of mothers, circumstances of intrauterine growth) are analyzed on representative samples. Special attention should be paid to the work on the evaluation in comparative and secular aspects of growth processes and indicators of sexual dimorphism of children under 3 years of age in the countries of the former USSR. Conclusion. Despite the difficulties in working with a rather specific contingent, the fact that these works, together with the results obtained, lead us to conclude that this stage of ontogenesis is represented to a large extent in the works of domestic anthropologists, which allows us to use these data both in the field of interdisciplinary and interdepartmental research.

“…Работа продолжает цикл исследований авторов, посвященных закономерностям изменчивости ПД размеров тела на восхоящем отрезке онтогенеза. Ранее на российских материалах было показано [Горбачева, Федотова, 2021;Gorbacheva, Fedotova, 2022], что на старте постнатального онтогенеза, в периоде новорожденности и грудном, вариации ПД размеров тела регулируются надпопуляционными и надэтническими механизмами: разная по полу цена адаптации к материнскому организму в периоде внутриутробного роста, компенсаторный рост в грудном периоде, выравнивающий обстоятельства (ограничения) пренатального развития. Этническая специфика ростовой динамики фиксируется не ранее второго полугодия первого года жизни.…”

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.
