К вопросу о программе исследования социально-экономических факторов ростового процесса у современных российских школьников

Abstract

Materials and methods. For the analysis, data on total body dimensions boys and girls 7-17 years old: body length and weight, chest girth; and according to the main socio-economic characteristics: the level of education and profession of the parents, the number of children in the family used. The value of the body mass index is calculated. A univariate discriminant analysis of the data normalized within each age and sex group was carried out (with a one-year interval, the average age is equal to an integer number of years). The statistical reliability of the differences in the average indicators for groups assessed depending on the edu-cation or profession of one of the parents, the number of children in the family, or the level of material security of the family. Results and discussion. The coefficients of correlation between socio-economic characteristics and the average values of the studied morphological characteristics by groups calculated, depending on the socio-economic characteristics. The two surveyed groups differ significantly in the socio-economic characteristics of the surveyed families. In modern Moscow, the nature of the connections between them has completely changed; accordingly, the nature of the noted statistically significant differences in the mean values of the studied morphological characteristics by groups has changed, depending on the specific socio-economic characteristics. Conclusions. The set of features describing the socio-economic status of the family of the examined child must correspond to the conditions prevailing in each specific situation, both from the point of view of information content and from the point of view of information availability.
