Abstract
to analyze the differences in the normative (reference) values of the body weight 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. The analysis showed that the greatest differences in this indicator were recorded in groups of children of primary school age, both among boys and girls. The highest values of reference indicators for body weight were determined in the younger age groups of boys and girls living in Yakutsk, and in older age groups - in those living in the industrial regions of the Republic of Sakha (Yakutia). The lowest values of these indicators were determined in children in rural areas of the region.
