Abstract

to analyze the differences in the normative (reference) values of the body length indicators of children and adolescents living in four ecological and geographical zones of the Republic of Sakha (Yakutia). Statistical data processing was carried out on 24,123 schoolchildren who do not have chronic diseases belonging to health groups I and II. Statistical, analytical, mathematical and sociological methods were used. Among boys, the highest level of statistically significant differences in body length was observed in the age groups of 12, 13 and 15-17 years, among girls - in the age groups of 13, 14 and 16 years. Higher reference values of body length indicators for boys and girls living in the industrial regions of the Republic of Sakha (Yakutia), lower - for those living in the Arctic zone of the Far North and rural areas of the Republic of Sakha (Yakutia), where the population is represented mainly by the indigenous peoples of the Far North.
