Correlations of integrative index of sexual maturation (IISM), constructed with the regard of mutual correlations of separate characteristics of sexual maturation, and dynamics of somatic parameters of children of school age is discussed. Material and methods. The research is based on the longitudinal study of Moscow school children aged 8–17, 121 boys and 125 girls, in 1982–1991. The programme includes the set of somatic characteristics – height, weight, trunk and leg length, pelvic and acromion diameters, chest diameters, chest and head circumferences, 4 skinfolds, dynamometry, standard parameters of sexual maturation. The construction of IISM is based on the method, used while constructing the typological characteristics of body build [Der-yabin, 1990, 2000, 2003, 2005]. The estimation of IISM with somatic characteristics in different age was realized using correlation coefficients. Results and discussion. Most of somatic charac-teristics, except for skinfolds, have low levels of correlations with IIMS through second child-hood, they increase during pubercy to the level of 0.7 in some cases with further decrease till the age of 17, which is most apparent for girls. There is a very low correlation of pubescence accel-eration with average levels of fat tissue development, while pubescence retardation is combined with some hypoadiposity. Conclusions. IISM is the informative index of sexual maturation proc-esses of school children, closely correlated with the dynamics of skeletal and muscle parameters through 8–17 years interval and independent from adiposity.
