ETHNIC-TERRITORIAL FEATURES OF SOME PARAMETERS OF THE LENGTH OF METACARPAL BONES OF FEMALE INDIVIDUALS OF THE TAJIKISTAN AND OF THE INDIA

In the last decade migration processes have significantly increased, which in turn determined the need for the accumulation of data on bone growth in people of different nationalities. In order to study the peculiarities of the growth of metacarpal bones (MB) in girls of Western India and Tajikistan, 309 radiographs of the right hand between the ages of 6 and 17 years were examined. On radiographs of the hand, the length and width of the diaphysis MB were measured. Using the parametric Pearson correlation coefficient - «r_p» and non-parametric Spearmen correlation coefficient - «r_s», we determined the relationship between the length and width of the MB diaphysis with age. Developed regression equations to determine the age of girls by the size of the MB. Girls in India and Tajikistan have a strong correlation between their age and MB length (rs ≥ 0,79). A comparative analysis of the correlation coefficients for the length of each MB with age allowed to establish differences between girls from Tajikistan and India. For Tajik girls the correlation between age and MB length was higher than that of their Indian peers. For Tajik girls, the greatest correlation with age was determined for the length of MB II (r_p=0,87; r_s=0,85) , then MB III and MB V, MB I, and a less close correlation was observed for MB IV (r_p=0,83; r_s=0,83). For girls in India, the closest correlation with age was determined for the length of MB III (r=0,82; r_s= 0,82), MB IV and MB V, then MB I and MB II (r_p=0,79; r_s= 0,80). The greatest correlation between the width of the diaphysis MB and age in girls of Tajikistan was determined in MB II (r_p=0,71; r_s=0,73), then MB III, MB IV, MB I and the least dependence for MB V (r_p=0,43; r_s=0,43). The closest correlation between MB diaphysis width and age in Indian girls was observed for MB II (r_p=0,64; r_s=0,65), then MB III, MB I, MB V and the lowest for MB IV (r_p=0,30; r_s=0,34). To determine the age by the size of the MB for girls of Tajikistan, the best result is obtained when calculating the parameter of the length of MB II, in the same time for Indian girls - of the length of MB II.
