Abstract
To assess the trends in the frequency of consanguineous marriages in the Israeli Arab population in the last 40 years, we conducted a two‐part study. For the first part, we re‐analyzed data from a nationwide study carried out in 1992, and for the second part, we undertook a new survey in 1998 in four locations: Taibe, Tira, Kalansuwa and Kafr Bara. Data regarding the frequency of consanguineous marriage in these four locations for the years 1961–1985 was extracted from the original survey, and for the years 1986–1998, from new questionnaires. The frequency of consanguineous marriage was highest in the period 1961–1965 (50.6%), but by the period 1981–1985 it had decreased to 40.6%. Over the whole time span of the 1992 study, a significant decrease was observed between the periods 1961–1975 and 1976–1985 (p<0.0001). In the four‐location study, there was a significant decrease in the frequency of consanguineous marriage from 52.9% in the period 1961–1970 to 32.8% in the period 1991–1998 (p=0.0006). We conclude that the custom of consanguineous marriage in the studied population is still extremely high, and preventive measures should be taken to decrease its frequency and associated complications.
