    Abstract:
    A retrospective sample survey of birth certificates from a Moscow maternity hospital over a 40-year period has revealed secular growth changes (involving mothers' stature, age at menarche, and four anthropometric traits in newborns) in two consecutive generations. Cohorts of mothers born in the period 1930-1949 showed high rates of acceleration. Age at menarche decreased in these cohorts at a rate of 12.5 months per 10 years, and a parallel gain in stature averaged 1.8 cm per 10 years; both rates were significantly higher than those for Western Europe. In later birth cohorts the acceleration in the maternal generation apparently ended. Anthropometric traits at birth (weight, body length, head and chest circumferences) show different patterns of secular changes from 1950 to 1990. According to multiple regression analysis, a temporal trend in the neonate body size might be mainly due to the parallel increase in mother's stature. The contribution of socioeconomic factors to the observed secular growth changes is discussed.
