The aim of this study was to assess preferences for sexual dimorphism in four somatic traits (height, muscle development, physical strength, and fat deposition) among males and females across eight populations differing in origin, culture, socio-economic and ecological conditions.

Materials and Methods. The sample consisted of 1501 individuals (610 males and 891 females) aged 17 to 39 years (mean age: 20.8 ± 4.3), representing eight populations residing in Russia: Buryats, Yakuts, Kalmyks, Tuvans, Kabardians, Balkars, and Russians (from Moscow and Tula). Data were collected from 2022 to 2024. To assess preferences for sexually dimorphic traits an author’s questionnaire was utilized.

Results and Discussion. In all samples, both men and women found pronounced sexual dimorphism in height, following generally accepted “male-taller norm”, to be attractive. The majority of men preferred slender women with low muscle development and physical strength, while women favored physically strong men with well-developed musculature. Population differences in anthropoaesthetic preferences were revealed. Kalmyks, Kabardians, and Balkars considered pronounced sexual dimorphism in height, musculature, and physical strength to be more attractive, whereas Yakuts and Russians from Moscow expressed less definitive preferences. In nearly all male groups, consistent associations were found between preferences for sexual dimorphism in height and physical strength, as well as muscle development and fat deposition. The most robust associations in female groups pertained to preferences for sexual dimorphism in height and physical strength, as well as muscle development and physical strength.

Conclusion. The identified anthropoaesthetic preferences related to the expression of sexually dimorphic traits across various somatic criteria reflect universal and culturally specific ideas about physical attractiveness, shaped by evolutionary and sociocultural factors.
