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(More)
Results of a total genetic demography study of females of postreproductive age from both parts of "splits" highland isolates of Dagestan, highlanders, and migrants to lowlands are described. The components of natural selection that were related to differential mortality and differential fertility were estimated in the highlanders and the migrants using Crow(More)
Xenobiotic-metabolizing genes (e.g., Cytochromes P450, GST, NAT2, and NQO1), folate metabolism genes (e.g., MTHFR and MTRR), and major histocompatibility complex genes (e.g., HLA-DQA1) play multiple roles in the organism functioning. In addition, AB0 is the most clinically significant high-polymorphic gene in transfusion and transplantation medicine.(More)
Medical records and questionnaire data have been used to analyze morphophysiological (the birth weight and length) and genetic demographic (maternal age and marriage structure) traits in a sample of children with orofacial malformations (OMs, cleft palate and/or cleft lip) living in Krasnodar krai, Russia. The sample of children with malformations(More)
Using marriage records, census data, and other statistical sources, some demographic parameters of Moscow population in 1955 and 1980 have been studied, such as age at marriage, birthplace, nationality and profession of permanent residents. Migration has been shown to be the main factor of Moscow population dynamics. Genetically significant, quantitative(More)
Based on data collected from urban residents by questionnaire, the basic parameters of the genetic-demographic structure of populations of the three megalopolises, i.e., Moscow, Kharkov, and Minsk, have been calculated, including the migration coefficients and their dynamics in generations, the radius of the cities migration attraction, the parameters of(More)
A genetic-demographic study of the dynamics of the Moscow population marriage structure, with respect to the age of marriage, birthplace and nationality of newlyweds has been carried out by means of sample analysis of 1955 and 1980 marriage records; some other demographic and statistic data obtained during several years were also used. The mean age of(More)
Genetic demographic characteristics and immunogenetic markers (blood groups ABO, Rhesus, MNSs, P, Duffy, Kidd, and Kell) have been studied in a group of 132 Russian cosmonauts and test subjects (CTSG). Analysis of pedigrees has shown a high exogamy in the preceding generations: almost half of the subjects have mixed ethnic background. According to the(More)
Geographic parameters of migration were analyzed on the basis of data on birthplaces of individuals who contracted marriages in Moscow 1955, 1980, and 1994 to 1995. It was shown that the relationship between the migration rate and distance significantly changed in the 1990s. Investigation of ethnic composition of migrants demonstrated that an increase of(More)
In an urban population with widespread birth control practice the distribution of the number of pregnancies, births and abortions was studied in a cohort of women of completed fertility. The mean number of pregnancies per woman was 4.03 +/- 0.08 (sigma = = 2.98); the mean number of births - 1.12 +/- 0.02 (sigma = 0.77). 7.4% of women which had completed(More)
