RETROSPECTIVE ANALYSIS OF THE STATE OF PHYSICAL DEVELOPMENT OF SCHOOLCHILDREN FOR THE LAST 60 YEARS ACCORDING TO DATA ALMATY CITY

The physical development of children is one of the main criteria for the health status of the child population, reflecting the influence of endogenous and exogenous factors. Dynamic study of schoolchildren's physical development allows one to determine the characteristics of the formations of their morphofunctional parameters and then influence the health of the whole population. The study of the orientation of time shifts in physical development has an important predictive preventive component and is the basis for updating regional standards every 5-10 years. Objective - to identify the main trends in the physical development of schoolchildren in Kazakhstan according to anthropometric measurements among schoolchildren of Almaty over the past 60 years (1956, 1972(2), 1983, 1989, 2005, 2017). Object of study: 13136 schoolchildren of 7-16 years old, various general education institutions (schools) of Almaty, who studied in 1956, in 1972, in 1983, in 1989, in 2005, and in 2017, which were used to carry out transverse and longitudinal studies of physical development using a standardized anthropometric method using standard tools. A comparative analysis of the basic indicators of physical development (length and body weight), conducted between 1956 and 2017, shows a pronounced tendency to increase them across all ages. The largest increase in basic body size in both boys and girls was in the period from 1956 to 1972 (p
