2Lomonosov Moscow State University, Biological Faculty, Department of Anthropology, Moscow, Russia Growth process of children reflects the level of ecological pressure of environment. The aim of this study is the secular dynamics of somatic parameters of Moscow newborn (body height and weight) and infants (body height and weight, head and chest circumferences) along with the continuous increase of anthropogenic stress in the megapolis during recent decades: increase of the level of technogenous pollution, the informational stress. Several newborn samples are revised: personal archive data (1952-53, 1973-74, 1982, 1990 years of birth) and data recently collected in Moscow out-patients clinics (2010-11 years of birth). Only firstborn newborn delivered in term were regarded. The total number includes 5 000 respondents. Samples of Infants aged 1-12 month are literary data (1930, 1940, 1950, 1960 years) and our own longitudinal sample collected on the base of Moscow district Marjino out-patients clinic in 2009.
Moscow newborn since 1950 till now demonstrate uninterrupted tendency of body length increase without any secular changes of body mass, which means the increase of leptosomy of body shape. The infants show the synchronous increase of body length and weight through 1930-40 – 1950-60 interval. The secular differences reach 0,8-1,2 of intragroup standard deviation for body length and 0,6-1,2 – for body mass. Further on the increase of body length takes place with the reducing rate while body mass demonstrated no changes since 1950-60 till now. Such combination of weight-height dynamics means the same increase of leptosomy of body shape of children of the 1st year of life as newborn used to experience. Secular dynamics of circumferences repeats the pattern of dynamics of body mass. The leptosomization and astenization tendencies were observed by many authors in Moscow schoolchildren during the second half of the 20thcentury. Contemporary Moscow preschoolers, schoolchildren and adolescents demonstrate stabilization of skeletal growth combined with the significant increase of adiposity. Thus, newborn and infants whose development is mediated by maternal organism and depends on postnatal care, repeat the secular tendencies of elder groups with some delay.
