The frequency of consanguinity in Konya, Turkey, and its medical effects.

This study was conducted in the town of Konya, Turkey, on 1120 randomly selected women to find out the overall rate of consanguineous marriages among couples. The frequency of consanguineous marriages was found to be 23.2%. It was found that 14.6% of this figure was first cousin marriages and the rest was 8.6%. Consanguineous marriages were higher among women born in villages compared to those born in provinces and the town center. Based on the findings, it was not too difficult to say: the higher the level of education of women, the lower the rate of consanguineous marriages. The number of children with an abnormality was high in consanguineous marriages, while the frequency of spontaneous abortion, still-birth and infant death remained the same.
