Introduction. Numerous publications have noted a general pattern: then higher are the parents’ educational and professional level, and then larger and heavier are their children, which is associated with a higher family income. The purpose of this work is to consider the variability of body composition indicators in schoolchildren 7–17 years old from the Saratov region depending the characteristics of the family’s socio-economic status proposed by us, and to evaluate the impact of the level of material prosperity on the main indicators of the physical development of children and adolescents. Materials and methods. The materials of the comprehensive survey in 2002–2004 children and adolescents 7–17 years old from the cities of the Saratov region, with a total number of 4266 people are used. The average normalized values of total sizes and 17 body composition indicators calculated by different methods were compared in each of 42 groups of boys or girls formed according to 3 gradations by one of 7 socio-economic factors. Results and discussion. There are significant (95%) differences in levels of total body size in children of both sexes, corresponding to the literature data: the higher the indicators of family income, the greater the values of morphological signs, magnitude of differences up to 0.7δ. Boys from large families have the smallest body sizes and very weak development of the fat component. With an increase in the educational and professional levels of mothers, sons have higher total fat-free mass, total water and percentage of fat mass, magnitude of differences 0.4δ–0.7δ. In girls, with an increase in the material income, educational and professional levels of mothers, almost all indicators are growing, except for body density, percentage of fat-free mass and percentage of water, magnitude of differences 0.4δ–0.7δ. Daughters of fathers with secondary professional level have the highest rates of development of the fat-free component (magnitude of differences 0.6δ) and average body size. Conclusions. There is sexual dimorphism in the variability of body composition indicators in school-aged children from families of various socio-economic status. In boys, the relationship between absolute indicators of body composition (reflecting body sizes) and factors of financial income of the family according to the traditional scheme is expressed. In girls – between relative indicators (reflecting the development of fat deposition) and the professional level of parents. In children of parents with high occupational levels, the ratio of fat to muscle component may indicate latent obesity. The method of calculating the body composition does not significantly affect the results of the analysis.
