The aim of our research was to study secular trends of body length and mass of newborns born in Moscow from 1952 to 2011 years, and to reveal the dynamics of primiparous women’s age and age of menarche. Materials and methods. In this article we analyzed data on five groups of newborns. Number of infants born in 1952 year was 174 persons, 1973-74 year of birth – 862 persons, 1981 year of birth – 1757 persons, 1990 year of birth – 1505 persons, 2010-11 year of birth – 694 persons. Information on newborns and their mothers was collected in archives of maternity homes and antenatal clinics in Moscow. Only first born, full-term infants, singletons were taken in this research. Results and discussion. Throughout the interval considered (1952-2011 years of birth) body length of boys and girls tends to continuously increase. Body length of either sex grew up in 0.3 cm from 1973 to 1980 years and in 0.4-0.5 cm from 1990 to 2011 years. Body mass of newborns haven’t reveal any secular trends. The combination of these two tendencies describes enhancement of leptosome constitution of Moscow newborns. Sexual dimorphism of body mass and length in the period under review is statistically significant and almost constant: about 1/3 of boys’ body size standard deviation. The dynamics of primiparae’s age is wavy – it decreases from 26.6 to 23.5 years in period of 1952 – 1981 years and increases again to 26.9 years from 1981 to 2011. The average age of menarche of primiparae significantly decreases from 1981 to 1990 and to 2010-11 years, the difference between 1990 and 2010-11 years isn’t statistically significant. We investigated relation between age of menarche and age of birth of primiparae and found out significant reduction of age of menarche from 13.5 to 13.1 years in the period from 1940th to 1970th years of birth and not significant rise to 13.2 years to 1980th. Conclusions. Our study revealed tendency to enhancement of leptosome constitution of newborns in Moscow from 1950th till now and showed that secular trends of primiparaes’ age and age of menarche aren’t related to somatical status dynamics of their newborn infants.
