BODY WEIGHT DYNAMICS OF PREPARATORY GROUPS’ CHILDREN AT PRESCHOOL EDUCATIONAL INSTITUTIONS IN KEMEROVO
Abstract
The aim of the research is to study the trends of changes in body weight of six and seven-year-old children attending the preparatory groups at preschool educational institutions. Materials and methods. The study was carried out with the voluntary informed agreement of the children's official representatives during 2017-2018 on the basis of the Health Center of the Kemerovo City Children’s Clinical Hospital N 1. 603 children attended preschool preparatory groups were under observation. There were 181 six-year-old boys (6 years and 6 months ± 3.33 months), 132 seven-year-old boys (7 years and 2 months ± 1.74 months), 174 six-year-old girls (6 years and 6 months ± 3.13 months), 116 seven-year-old girls (7 years and 2 months ± 1.85 months). All children were examined for anthropometric parameters of physical development using the children's computer program module «Antropo 2009 1.3.0.5». The diet was evaluated by the survey among parents while their children did not attend preschool institutions due to holidays, planned repair works within the institution or quarantine measures. Conclusion. The study of the physical development of preparatory groups’ children at preschool educational institutions showed that only every third child had harmonious physical development. Body weight in all age and sex groups was characterized by heterogeneity and significant fluctuations in relation to the predicted values. Children who had physical development below average were overweight (60.0 %), and those with a low physical development level were underweight. All children with above average level and high level of physical development had a tendency to weight deficit (55.56 % and 54.16 %), while overweight percentage was 44.44 % and 45.85 %. To assess physical development in the groups of 6 and 7-year-old boys and 6-year-old girls the method of standard deviation was preferable. With the group of 7-year-old girls it was equally possible to use both methods of centile tables and standard deviation. Feeding children at home contradicted the principles of rationality recommended by the health standards and regulations.
