Abstract
Material and Methods. Data of monitoring of anthropometric signs of schoolchildren aged of 7-15 years (2005-2013) living in a rural settlement of the Sverdlovsk region are presented.
Results. The average growth of schoolchildren varies from 122 cm at the age of 7 to 155 cm at the age of 13 years. At 14 years, the average height of boys exceeds in comparison with girls by 4 cm, and at 15 years - by 10 cm. The average body weight of 7-years-olds is 23 kg, 14-year-old boys are on average heavier than girls by 2.5 kg, and at the age of 15 years - by 10 kg. The first cross-section of the dynamics curves of the studied somatometric signs (height, body weight, chest circumference) in schoolchildren of different genders is observed at the age of 10-11 years, the second is from 13 to 14 years. The distributions by mass of the body are asymmetric, in height is close to normal. The proportion of both boys and girls aged 8-11 years in the modal distribution classes ranges from 40 to 60%. The revealed average values for the growth of schoolchildren are lower than in the corresponding period in Moscow but increased from 2008 to 2012. And they are close to all-Russian values in the late XX and early XXI centuries. The observed dynamics can be related to the asynchrony and unevenness of the process of acceleration, the influence of urbanization. One of the reasons for the lagging behind of rural schoolchildren from urban peers is likely to be associated with a lower standard of living for the rural population. It can be assumed that an increase in this level determines also smaller differences between the indices of rural and urban children and adolescents.
