    Abstract:
    Temporal dynamics of morphophysiological characteristics variability in generations of newborn children and their mothers living in Moscow is considered in this work. The study is based on histories of newborn children and histories of delivery in 1950, 1955, 1960, 1965, 1970, 1975, and 1980. High rate of acceleration was exposed for women born since 1930. Decrease of menarche age in this age cohorts was 12.5 months per decade and three times exceed correspondent index of European countries. Average increase of body length in the age cohorts was 1.9 cm per decade and twice exceeded analogous index of European countries. Variability of four anthropometric characteristics (body weight, body length, circumference of head and chest) of natural time delivered newborn children was studied. The characteristic values were shown to increase from 1950 to 1980. According to the data of analysis, the temporal dynamics in newborn children was not connected with improvement of environmental conditions during the period of pregnancy but caused by epochal changes in maternal generation. A possible connection between the temporal dynamics of morphophysiological characteristics in newborn children and their mothers and changes in genofond of outbred population of the European territory of Russia is discussed.
