[Main anthropometric indicators of children and adolescents living in the Chuvash Republic in the dynamics of 137 years].

Anthropometric studies conducted in 1884, 1928, 1946, 1965 and 1999 to study the characteristics of growth and weight indicators of children living in the territory of modern Chuvashia, partly reflected the influence of the living conditions of children in certain historical periods of the country's development: revolutions, civil and domestic wars, post-war stabilization, «perestroika». Over the last 22-year period, from 1999 to 2021, there has been the largest increase in the growth rate of indicators of the physical development of children and adolescents, which is considered as a positive trend, a manifestation of ongoing acceleration processes. It was revealed that in modern children, physiological growth jumps in comparison with their peers in 1884, 1930, and 1999 occur earlier - in the prepubertal period.
