Spatial Analysis of the Aptitude to Late Maternity on the Island of Sardinia
This study examines local heterogeneity in the aptitude of Sardinian mothers towards late reproduction, and explores its temporal persistence and association with both post-reproductive longevity and propensity to consanguineous marriage. Data on women's fertility from 1961 and birth records for 1980–1996 from Vital Statistics were analysed by means of the following indicators: the incidence of old mothers at last childbirth, female mortality (19…
Late reproduction behaviour in Sardinia
Trends in Childbearing and Stillbirth Risk
In Italy, as in all Western countries, the almost monotonic decline in fertility observed since the 1960s has been paralleled until the beginning of the 1980s by a decrease in maternal age at delivery. Since then, age at marriage and at childbearing has been increasing and marital fertility has continued to decrease. By 1994 Italy showed extreme values of low total fertility rate (1.22) and of high mean maternal age at delivery (29.7). For the pe…
Paternal HLA Genotype and Offspring Sex Ratio
For twenty years, W.H. James has been proposing that the sex hormone level of both parents could control at least a quota of the secondary sex ratio variation at the time of conception. Observations supporting this hypothesis have come from investigations on some diseases related to the human leukocyte antigen (HLA). In the present study on 1102 healthy Italian families, we investigated the potential effect on the offspring sex ratio of HLA-B all…
Sex Ratio at Reproductive Age
The radical improvement in living conditions experienced in Italy during the last century caused a reduction in male extra-mortality during the prereproductive years. As a consequence, a progressive increase in the sex ratio at the beginning of the reproductive age (15-19 years) occurred, so that in recent times the sex ratio in the young adult population has approached the almost constant value of 1.06 observed at birth. We calculated that the s…
Malaria, demographic parameters and thalassemia in Southern Italy
Fertility and malaria in Sardinia
Using data from the 1961 Italian census, the study of fertility in Sardinia when malaria was endemic shows differential fertility between women living in areas with differing degrees of malaria. Cultural factors measured by women's level of education are negatively correlated with fertility, just as the 'urban' character of the area in which the women lived has a lowering effect on the fertility rate. The hypothesis of differential mortality acco…
Migration pattern and genetic marker distribution of the Afro-American population of Bluefields, Nicaragua
On a sample of the population of mixed African ancestry living in Bluefields, Nicaragua, the pattern of migration and the distribution of red cell and serum genetic markers have been studied. It is concluded that, in spite of a considerable level of internal and external migration, a distinctive genetic structure is maintained by the population. Moreover, a strongly negative assortative mating can be observed between people inhabiting the western…
Variation of the human secondary sex ratio and lethal recessive X-linked mutations
Sex ratio at birth was studied in relation to grandparental age, to enquire into the effect of the accumulation of X-linked recessive lethal mutations. From the data of the tenth census of the Italian population two samples of women having a live-born only child were examined: the first from some provinces of northern and central Italy, the second from the island of Sardinia. Besides maternal grandfather's and grandmother's ages, the mother's age…
Correlation Between Father's Age and Husband's Age: A Case of Imprinting
Correlation between father's age and husband's age
Analysis of the data from the tenth Italian census shows that women born to older fathers tend to marry older men. The correlations between the ages of the father and the husband in various situations were always found to be positive and significant when the age of the woman and her educational level were held constant. Correlation coefficients are higher in rural and economically less developed areas. Behavioural ‘imprinting’ is suggested as a p…
