Intra- and Inter-population Variability and Evaluation of the Physical Development of a Young Generation

Abstract

This study is concerned with long-term anthropometric examinations of children and adolescents aged 3–17 years in Moscow (over 10,500 persons, longitudinal and cross-sectional). Population variability of physical development was analyzed by means of regional estimation tables, which were developed on the basis of a regression analysis (scale of the regression of body mass to body length within a range from M−1σ_R to M+2σ_R) and used for individual and group diagnostics taking into account age and sex. Such an approach allowed for the determination of the dynamics of the variability of Moscow schoolchildren from decade to decade (inter-population variability) and variations due to social differences (intra-population variability).
