Features of quantitative content of bone component in women of different age and сonstitution

Abstract

BACKGROUND: Body component composition, including bone components, is dynamic. Obtaining objective information on body composition will allow solving a significant number of applied and theoretical problems in the field of personalized medicine. AIM: To study the quantitative parameters of the bone component of the body in women of different age groups while taking body types into account. MATERIAL AND METHODS: The physical status of 580 female Kyrgyz women was studied. The women were allocated into three age groups: the youth period (1620 years) with 210 girls, the first period of adulthood (2135 years) with 186 women, and the second period of adulthood (3655 years) with 184 women. Somatotyping was carried out in accordance with the scheme of GalantNikityukChtetsov (I.B. Galant, 1927; V.P. Chtetsov, 1979; B.А. Nikityuk, 1983) with informed consent. Bone component content was determined by using the method of J. Matiegka (1921). RESULTS: A total of 20, 32, 33, and 15% of the women were of the leptosomal, mesosomal, megalosomal, and indefinite somatotypes. Compared with the absolute content of the bone component in girls with the leptosomal somatotype, that of girls with the mesosomal somatotype almost did not change, that of girls with the megalosomal somatotype had increased by 1.2 times (p 0.05), and that of girls with the indefinite somatotype had increased by 1.1 times (p 0.05). The percentage of the bone component of the body in girls with the leptosomal somatotype was lower by 1.2, 1.3, and 1.5 times (all p 0.05) than that in girls with the mesosomal, megalosomal, and indefinite somatotypes, respectively. In women in the first period of adulthood, the percentage of leptosomal somatotypes was 1.4 times lower than that of the mesosomal, megalosomal and indeterminate somatotypes (all p 0.05), respectively. In women in the second period of adulthood, the percentage of leptosomal somatotypes was 1.4, 1.5, and 1.6 times lower than that of the mesosomal, megalosomal, and indefinite somatotypes (all p 0.05), respectively. CONCLUSION: The absolute mass of the bone component of the body had minimal values in girls and women of mature age of leptosomal somatotypes (6.07.1 kg) and maximum values in megalosomal somatotypes (6.69.2 kg). In women of the second period of adulthood, in comparison with girls, its percentage in representatives of all somatotypes decreases (by 1.11.2 times).
