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. © 2023.

Introduction. This review is a continuation of the research devoted to the assessment of the development of auxology in Russian anthropology. The first part was devoted to a comprehensive assessment of the processes of growth and development of children from birth to 3 years old, living both in our country and in the countries of the near abroad. The analyzed sources describe factors influencing growth processes (evolutionary, climatic, geographical, ethnic and genetic factors, constitutional features of mothers, circumstances of intrauterine growth) [Permiakova, 2023]. This article examines and describes in more detail the main activities of auxologists, as well as physicians and psychologists working both within our country and in cooperation with foreign researchers from various academic institutions.
Materials and methods. In this part of the work, the author analyzed articles devoted to the comprehensive assessment of physical development (as well as factors affecting it) of the school and student contingent living in Russia and some other countries. All these articles were published in Moscow University Anthropology Bulletin from 2009 to 2022.
Results and discussion. Works in the designated area, on the one hand, analyze the physical development of children and youth of the Moscow region, on the other hand, assess the differences in the rates and dynamics of growth processes of residents of different regions of our country and abroad, including the secular aspect. In addition, representative samples are used to analyze socio-economic factors affecting these processes and determining the features of their course in a particular territory. Complex studies involving the relationship of somatic development indicators not only with socio-economic or environmental parameters, but also the psychological characteristics of the subjects are also important.
Conclusion. The number of works devoted to the subject under study is quite numerous, which allows us to speak about the undiminished interest of domestic anthropologists in studying the problems of growth and development. The complex nature of most of them, among other things, indicates an integrative approach to solving the problems posed to this field of science. © 2023.

Introduction. Bioelectrical impedance analysis (BIA) is an indirect method of body composition assessment. The equipment for BIA measurements is produced in many countries including Russia and may differ in electrical current frequencies, measurement schemes and built-in algorithms for the evaluation of body composition. In view of this, body composition estimates from various BIA instruments may be inconsistent which limits the ability to combine and generalize BIA data. Our purpose was to analyze the consistency and possibility of joint use of the BIA data obtained using the ABC-01 ‘Medas’ (SRC Medas, Moscow) and Diamant-AIST (LLC Diamant, St. Petersburg) instruments in adults.
Materials and methods. 185 adult volunteers (107 women and 78 men) aged 18 to 61 years were examined according to the standard anthropometric measurement protocol and on the basis of paired consecutive measurements with the bioimpedance body composition instruments ABC-01 ‘Medas’ and Diamant-AIST. The estimates of fat-free mass (FFM), body fat (BF) and percentage body fat (%BF) were compared. Mutual calibration of the bioimpedance data was carried out based on transformation of the Diamant-AIST data using a conversion formula between the ABC-01 ‘Medas’ and Diamant-AIST resistances and subsequent application the ABC-01 ‘Medas’ body composition assessment algorithm.
Results. There were significant differences in the median values of FFM, BF and %BF estimates provided by the ABC-01 ‘Medas’ and Diamant-AIST instruments. The FFM values in females using the ABC-01 ‘Medas’ instrument were significantly lower, and the BF and %BF were significantly higher as compared to the Diamant-AIST data. In males, the inverse relationship was observed while maintaining significant differences between the medians.
The differences in paired estimates of body composition data provided by the ABC-01 ‘Medas’ instrument and the transformed Diamant-AIST data in males and females, respectively, were statistically insignificant. Also, the confidence intervals for the differences of paired body composition estimates reduced essentially, but still not ensured good consistency of individual body composition data.
Conclusions. Significant differences in paired values of fat-free mass, fat mass and relative body fat using the ABC-01 ‘Medas’ and Diamant-AIST bioimpedance instruments are obtained. The possibility of mutual calibration and joint analysis of the related bioimpedance data at the group level is established. © 2023. This work is licensed under a CC BY 4.0 license.
Introduction. This work is devoted to the study of some aspects of age and (or) temporal variability of a number of morphological features of the head and face in the adult Chuvash population in Bashkiria. The objectives of the study were to analyze and assess the presence and degree of morphological changes on the skull of an adult according to a number of signs included in the program on ethnic anthropology, as well as to study their possible connection with age-related transformations or acceleration of development and secular trend.
Materials and methods. The surveys were conducted in two districts of Bashkiria, Aurgazinsky and Bizhbulyaksky, in villages with a predominantly Chuvash population. The material was collected in 1999, in total, data were obtained for 361 men and 352 women born from 1915 to 1980. The paper studied the temporal and age variability of the following features: longitudinal, transverse, zygomatic and mandibular dimeters, the smallest width of the forehead, measured the morphological height of the face (from the nasion) and the circumference of the head, calculated the head index. The material was collected by the same researcher. The data were divided into 11 age groups in increments of 5 years, starting in 1925. In each group, the average values of the features and standard deviations were calculated. For all signs, scatter diagrams of the values of signs vs year of birth are presented.
Results and discussion. The most stable signs in terms of age were the minimal width of the forehead, head circumference and mandibular diameters. The magnitude of the head index varies significantly due to age-related changes in the transverse and longitudinal diameters of the head, which determine the magnitude of the index. The age-related decrease or stable condition of the head pointer, according to G.L. Hit’ [1968], contradicts our observations. For most indicators, with the exception of morphological height of the face and zygomatic diameter, no pronounced changes were found, which may be due to local features of the development of the examined group.
Conclusion. The conducted studies have shown that for a more thorough study of the problem under consideration, it is necessary to attract additional materials collected at different times and under different environmental conditions for a close group (for example, in stable populations of Khalkha Mongols). © 2023.This work is licensed under a CC BY 4.0 license.
Introduction. This work continues the series of articles devoted to the assessment of the main directions of auxology development in Russian anthropology. This part presents and describes the work of the staff of the Research Institute and Museum of Anthropology of Lomonosov Moscow State University, the Department of Anthropology of the Faculty of Biology of Lomonosov Moscow State University, as well as the Russian University Sport (SCOLIPE) and the Federal Science Center of Physical Culture and Sport (VNIIFK).
Materials and methods. In this part of the work, articles devoted to the comprehensive assessment of the research of physical development in the context of psychology, psychophysiology, genetics and sports anthropology, which were published in the «Lomonosov Journal of Anthropology (Moscow University Anthropology Bulletin)» from 2009 to 2022 were used as a source of information.
Results and discussion. The described works evaluate, firstly, the psychosomatic connections of self-esteem and soma parameters that determine it, as well as the specifics of the processes of growth and adaptation in biological and psychological aspects. Secondly, the intra-group variability of neurophysiological parameters (EEG parameters) and the analysis of their correlations with somatic indicators are considered. Thirdly, the contribution of genetic factors to the development of morphological trait systems, primarily associated with increased body weight and obesity, is evaluated. In addition, the results of studies devoted to the search for predictors of sports success and the analysis of the physical status of athletes of various specializations are presented.
Conclusion. The number of works similar to those described in this review is steadily growing every year, which suggests an increasing integrative nature of anthropological research.

Introduction. The purpose of the study is to characterize and to compare the indicators of fat deposition and body composition in groups of urban children and adolescents of the Republic of Mongolia in various living conditions.
Materials and methods. The material for this study was the results of a comprehensive survey of 5 612 Mongolian children and adolescents aged 9-17 years (born and permanently residing in the capital city of Ulaanbaatar). In accordance with the objectives of the study, the body circumferences, the skinfolds, as well as the body mass components evaluated by bioimpedance technique were analyzed.
Results. Based on the obtained statistical parameters of the studied features, as well as on the results of their comparison in the studied groups, it can be concluded that the value of most of the considered indicators in children and adolescents living in apartments is higher than in their peers living in yurts.
Discussion. The increase in body weight in boys living in the apartments, recorded according to the results of our previous work, is associated with an increase in active cell mass, and, as a result, – lean body mass. To a lesser extent, judging by the existing differences, its value is influenced by the fat component. While the parameters of fat deposition show a small number of significant differences, unlike circumferences, it can also be concluded that the variability of the girths is more associated with the development of the muscular component. Similar patterns were obtained for girls. However, in this case they are less pronounced, but also correspond to the previously obtained results.
Conclusion. The general increase in the welfare of the population of Ulaanbaatar and significant improvement in the living conditions of the younger generation, has a positive effect on the youth physical development, primarily due to a more pronounced increase in the metabolically active components of body weight. This may be considered as an important reflection of the socio-political processes taking place in the country. © 2024. This work is licensed under a CC BY 4.0 license
Introduction. This paper discusses the results of the analysis of intra- and inter-population variability in spatial and temporal aspects among the indigenous population of the Republic of Tuva, who have preserved to a certain extent the traditional way of life.
Materials and methods. The material for the article is the results of complex anthropological expeditions of the Anuchin Research Institute and the Museum of Anthropology to the Republic of Tuva, implemented in the period from 2016 to 2022 in cooperation with Tuva State University and the Medical Genetic Research Center.
Results and discussion. According to the results of the conducted research, the existing ideas about the structure of intergroup variability of related Altai-Sayan peoples (Tuvans, Tuvans-Todzhins, Tsaatans, Altaians) have been expanded, the anthropological and genetic community of Tsaatans and the indigenous population of Tuva has been confirmed. Also, for the population of the republic over the past 40 years, the detected maladaptive changes caused by socio-cultural changes and violation of the traditional way of life have been described for the first time. Among other things, a significant (2.5-3 years) acceleration of ontogenesis in the younger generation was shown in both urban and rural conditions, an increase in total body size (secular trend), acceleration of puberty, changes in body composition, which confirms a violation of adaptation in the populations of the indigenous Tuvan population. Based on the latest data obtained, data on changes in the structure of intra-population variability and manifestations of the secular trend in most regions of the Republic have been confirmed and supplemented.
Conclusion. The further task of anthropological research of an ethnogenetic orientation is to assess as many aspects as possible that fall under the influence of the described factors, both in Tuvan and in other groups. © 2024. This work is licensed under a CC BY 4.0 license
Introduction. In our recent publications, we have established the possibility of using bioimpedance measurements to assess the Heath-Carter somatotype in different age groups. We aimed to develop unified formulas for calculating the somatotype in children and adults, evaluate their accuracy based on age and body mass index, and improve the somatotyping protocol in bioimpedance analyzer software.
Materials and methods. Data from our previous studies on comprehensive anthropometry and related BIA measurements were considered. The main group consisted of ethnic Russians aged 7-59, who were examined in Moscow, Arkhangelsk, Arkhangelsk Region, Elista, and Samara (N=4,296). The comparison group 1 included ethnic Russians aged 16-86 from the Krasnoyarsk Region (N=3,954). The comparison group 2 consisted of ethnic Kalmyks aged 8-25 from Elista (N=940). Using the data of the main group, bioimpedance predictive formulas for Endomorphy (ENDOBIA) and Mesomorphy (MESOBIA) ratings were obtained. We evaluated their accuracy in different subgroups of the main group and the comparison groups.
Results. The obtained formulas were as follows: ENDOBIA = -3,411.8/R50 + 0.942´BMI – 0.00938´BMI2 – 0.0235´Ht – 0.28´Sex + 0.034´Age – 2.69 (N=4,296; R2=0.84; SEE=0.76); MESOBIA = 1,531.8/R50 + 0.302´BMI – 0.0529´Ht + 0.57´Sex – 0.032´Age + 4.52 (N=4,296; R2=0.87; SEE=0.48). These were relatively accurate for the age range 7-40 years for males and 7-59 years for females, but less accurate outside these age ranges or at high BMI values. Based on this, we also suggested formulas for obese people: ENDOBIA = -2,569/R50 + 0.854´BMI – 0.0087´BMI2 – 0.0263´Ht – 0.032´Sex + 0.018´Age – 1.60 (N=296; R2=0.69; SEE=0.87); MESOBIA = 1,567/R50 + 0.55´BMI – 0.00512´BMI2 – 0.0524´Ht + 0.42´Sex – 0.035´Age + 1.66 (N=296; R2=0.62; SEE=0.64). The formulas were integrated into the ABC-02 'Medas' (SRC Medas, Russia) BIA instrument software.
Conclusions. Our findings expand the possibilities for assessing the somatotype and studying its variability. Using uniform calculation formulas for children and adults will help improve comparability of estimates and validity of comparisons. © 2025. This work is licensed under a CC BY 4.0 license
Introduction. The present study is devoted to the assessment of the association of two indicators of biological age (menarche age and peak height velocity) through the upward segment of ontogenesis and their joint informativeness.
Materials and methods. The analysis involved a block of samples of female adolescents (N=43) from the territory of the Russian Federation and neighboring countries, as well as the archival materials (N=4) collected as part of the work of the Laboratory of Applied Anthropology with the direct participation of one of the authors in the 1980s. Pearson correlation coefficients were used to assess the relationship between growth rates (PHV) and associated indicators with menarche age.
Results and discussion. It has been shown that the age of menarche is significantly positively associated with both the age of onset of peak height velocity and the maximum increase in body height during this peak. Statistically significant negative associations were recorded for the age of menarche and the year of the survey, which once again confirms the existence of a secular trend in the development of the adolescent population of our country and neighboring territories (the former USSR bloc). This is also evidenced by the positive relationship between the year of examination and the maximum increase in average body height during the peak height velocity. In the secular aspect, there is a tendency towards a gradual convergence of the parallel decreasing timing of the onset of menarche and the peak height velocity in Moscow girls examined over a period of more than 80 years. The transition to the onset of earlier puberty is smooth, whereas for the peak of the growth rate, this process is more intense in the interval from 1928 to 1956 (and the difference between them is maximal), which may indicate a greater sensitivity of the latter to the social cataclysms detected at this stage.
Conclusion. Our results on the correlation of the ages of menarche and peak height velocity allow us to make a cautious conclusion about the possibility of using the latter as an indicator of the chronobiological status of the population. © 2025. This work is licensed under a CC BY 4.0 license
