This research aims at studying the influence of ecological factors on the maturation rates of hand and wrist bones in children and adolescents. It is based on the radiographs of the left hands, collected in the course of the expeditions of the Institute and Museum of Anthropology through 1964-2013 periods in 19 ethno-territorial child groups, aged 8-17 years, with the total number of 6456 individuals. The Tanner-Whitehouse method (TW-2) was used to determine skeletal maturation. As to the European part of the former USSR the highest rates of skeletal maturation belong to the rural school children of Arkhangelsk region and Karelians of Olonetski region with the exceeding of skeletal age compared to chronological almost through the whole age interval. In the groups of Russians of the Yaroslavl region and Byelorussians the skeletal age falls behind chronological, which is stronger manifested in Byelorussian girls from longevity population (over 0.5 years). Maturation rates of hand skeleton of Chuvashs and Bashkirs are close to each other and 0.25 years lower than British standards. Significant changes of maturation rates of the hand and wrist bones through 25 years occurred in Abkhazia. The results of skeletal age of Abkhazian children in 2004 showed significant acceleration of maturation rates in the long-lived population of the Abkhazians. The changes are more evident in the population of the Ochamchiry region as compared to Gudauta region. The differences between longevity population of Chlow with the delayed rates of physical development and the control group from Duripsh, revealed in the 1970 – 1980 study, almost disappeared. Child groups of Central Asia, Khalkha-Mongolians and Tuvinians had the slowest maturation rate of hand skeleton, 0.8 years less than British standards. Altaians and Stolypin’s migrants descendants are characterized by the accelerated rate of physical development and high maturation rates of hand skeleton (0.4 years above the standard). In the Middle Asian region the highest maturation rates belong to the Turkmen urban school children from Chardzhev, the lowest maturation rate in this region is seen in the rural Tajik children from Varukh. Growth and maturation rates depend on various environmental factor: climatic, geographic and social. Differences of skeletal maturation in the observed groups may be interpreted in the context of maintaining (Khalkha-Mongols, Tuvinians, and Tajiks) or transformation (Turkmen, Chuvashs, Bashkirs, Altaians, Russians) of the traditional way of life. Social stress, connected with the military actions, caused the acceleration of maturation rates in the longevity group of the Abkhazians. Longevity populations were traditionally characterized by the low rates of growth and development (Abkhazians till 1991, Belorussians).
