[Regularities of physical development of Chukotka children aged 8-12 years]
Abstract:
School children in Chukotka aged 8-12 years were examined to study the characteristics of their physical development and its association with age, sex, and ethnicity. The study demonstrated that the migrants had higher values of body length and body mass, with a step-wise pattern of their increase, higher body fat component content as compared with the aborigines. The migrants showed higher circumferential dimensions, while the growth rate of these parameters was higher in aborigines. Maximal growth rates of extremity diameters were different in specific ethnic groups, while the skeletal mass was greater in migrants. In aborigine boys more active thorax growth was found, while aborigine girls had higher pelvic growth rate. Migrants were shown to have higher muscular and bone mass, than aborigines.
