Physical development in Tuvinian adolescents

It was found that mean values of height and mass in 13-14-year-old indigenous Tuvinian children were increased for the last 26 years. We have found gender difference in a chronological dynamics of a yearly body mass and height increases. As for the last ten years, these changes correspond to a harmonic physical development only for the boys of 13. At the same time we observed an insufficient increase in body mass and significant blood pressure increase in senior boys. A yearly percentage of the increase in blood pressure in junior boys was the same as mass increase, but among the senior children the increase in blood pressure was greater compared with mass increase. In the 70-80s, the indices of body mass and height increases for Tuvinian girls and boys were the same.
