title: Characteristics of the anthropometric measures and biological age of girls of Yakut ethnicity depending on tanner's index.
abstract: BACKGROUND
  severe climatic conditions of Yakutia influence the human morphofunctional status and it requires a comprehensive biomedical researches. The aim of this study was to examine the characteristics of the anthropometric measures and biological age of Yakut girls aged 16-20 depending on Tanner's index.
  
  
  METHODS
  the analysis of anthropometric examination of 1276 girls is presented. Anthropometric measurements were performed using the method of V.V. Bunak (1941). The absolute values of the main components of the body were estimated according to Matiegka's formula (1921). The body mass index (BMI) was used. The type of body build was determined by Tanner's index (1968). Biological age was estimated by the coefficient of aging rate (A.G. Gorelkin, B.B. Pinkhasov, 2010). Obtained material was processed by the method of variation statistics with the use of SPSS (version 17.0). We used the methods of parametric and nonparametric statistics.
  
  
  RESULTS
  the constitutional characteristics of girls have revealed the predominance of mesomorphic body type. Values of fat and bone body components had no significant difference depending on the body type by Tanner. Significant differences between the parameters of the pelvis and the amount of muscle body component were detected in the girls of gynemorphic and andromorphic body types.
  
  
  CONCLUSIONS
  we revealed ethno-territorial differences among girls, which are characterized by the predominance in Yakut girls of the mesomorphic type of constitution by Tanner's index. The study of the indicators of biological age has elucidated constitutional differences.
