Sexual Dimorphism of Somatic Parameters and Body Proportions in Modern Balkars and Kabardians

The aim of this study was to assess the level of sexual dimorphism of somatic parameters and body proportions in urban samples of Kabardians and Balkars. Materials and methods. All materials for this study were obtained during a survey of university students in Nalchik (Kabardino-Balkaria) in 2023. Anthropometric data on 317 individuals (135 males and 182 females), aged from 17 to 23 years (the average age was 18,81±1.49) are presented in this paper. The analysis included 19 somatic parameters and several indices characterizing body proportions. To evaluate the level of sex differences in somatic parameters, Student’s t-test was used. For each of the analyzed somatic characteristics, the coefficient of sexual dimorphism was calculated. Results. The results of the study showed a comparable level of somatic sexual dimorphism in the samples of Kabardians and Balkars. In both studied groups, males are larger than females, as evidenced by the positive values of coefficients of sexual dimorphism of total body sizes (except body mass index). Maximum degree of sexual dimorphism was observed in the longitudinal and transverse parameters of the skeleton. Body height and limbs lengths, as well as skeletal robustness, are greater in males compared to females in both ethnic groups. The values of almost all circumferences were higher in men. For most of the studied somatic parameters, the coefficients of sexual dimorphism are lower in Balkarians, except body height and limbs length. Conclusion. There were no statistically significant differences in the mean values of somatic parameters in the groups modern urban Balkars and Kabardians. Sexual dimorphism of the majority of the analyzed characteristics was similar in both studied samples. © 2025. This work is licensed under a CC BY 4.0 license
