The aim of the study was to study the linear parameters (length and width of the diaphysis) of metacarpals (MB) in males of Tajik nationality permanently residing in Tajikistan in the age aspect, as well as establishing the possibility of using linear MB parameters to determine the age of the examined. Material and methods . An examination of 117 X-rays was carried out in males of Tajik nationality aged 6-17 years living in Kanibadam in Tajikistan. The length of the MB, the width of the diaphysis of the MB were studied on the radiographs. The relationship between the length and width of the MB diaphysis with age was determined using the Pearson's parametric correlation coefficient - «r» and the nonparametric correlation coefficient - «rs». Comparison of the results with the size of MB in St. Petersburg residents was made. Results. Morphometric examination showed that in boys in Tajikistan, the length of the MB and the width of the diaphysis of the MB significantly increased with age, which is confirmed by the data of the correlation analysis. Dependence of the length and width of the MB on age is described by the linear regression equation, which is an analytical solution to the question of the nature of the dependence of the length and width of the MB diaphysis and the age of the examined. The presence of differences in the size of MB in different age periods was found in boys in Russia and Tajikistan, especially at the age of 14 years. Ethno-territorial differences are more often expressed in the width of the MB than in the length. Conclusions. It was established, that the correlation between the age of the examined and the length of the MB is closer than between the age and the width of the MB diaphysis. To determine the age of the examinee, it is better to use the MB length parameters than the width of the MB. The highest reliability in determining the age of males in Tajikistan from the data obtained was determined according to the length of MB II, and the lowest index was the width of the MB V diaphysis.
