>>53734057 >Qatar: Historically, populations of Qatar have engaged in consanguineous relationships of all kinds, leading to high risk of inheriting genetic diseases. In 2014, a published study discovered that 5.2% of the Qatari population suffers from hereditary hearing loss. Reports illustrate that of the affected individuals, the majority were descendants of a consanguineous relationship. Even more so, molecular testing confirmed a high level of homogeneity and inbreeding coefficient among patients suffering from hereditary hearing loss. >Iran: A recent study done on the prevalence of consanguinity in Iran determined that about 37% of the marriages were consanguineous with the majority being among rural couples, women marrying at a younger age, older marriage cohorts and women with lower levels of education. Thus, these results show a significant correlation between prevalence of inbreeding and low levels of education/limited access to education. However, since the nation is progressing towards prompt urbanization and expanding educational and employment opportunities, the frequency of inbreeding should be on a decline for future generations. Thereby, decreasing the incidence of recessive genetic disorders and promoting genetic diversity. >Afghanistan and Lebanon: Populations within Afghanistan and Lebanon have also showed elevated levels of consanguinity. Studies determined that in Afghanistan, inbreeding was more heavily practiced in the more rural, western and southern regions. In Lebanon, a study focused on the dominating Shi'a populations and ascertained that about 28% of the marriages were consanguineous

Moreover, of the 200 families studied, those that were consanguineous were found to be far less educated. Thus, parental education plays a role in the frequency of inbreeding. This would explain why western, generally more educated countries, inbreed far less than in the developing world. >Israel: The Bedouin population in Israel has commonly practiced consanguinity throughout their existence, with studies illustrating its prevalence in modern day still. In recent years, of the Bedouin women studied, 45% of the women have been found to be in a consanguineous relationship of sort, with first cousin marriages the most common. The level of education and age of marriage were found to be significantly correlated with consanguinity, with lower levels of education and younger age of marriage influencing higher bloodline marriage rates. Evidently, efforts should be made to better educate the population on the repercussions of inbreeding in hopes to decrease their risk of congenital malformations and genetic diseases. While rates of inbreeding may still be high, those of Israeli Arabs have been decreasing. A 2010 study analyzed the rate of consanguineous marriages among Israeli Arabs from 2000-2009 and ascertained a steady decline from roughly 36% to 24%. Similar to the Bedouin population, most of the women who engaged in consanguinity married at a younger age, thus premarital counseling is highly advised to prevent such statistics. >Aside from the Middle East, north African territories such as Tunisia and Egypt experience similar consanguinity frequencies and correlations
