Abstract

Benghazi represents Libyan population since it is a mixture of Libyan tribes from east, west and south of Libya. This study is carried out to investigate the prevalence of consanguineous marriage in sample of Libyan population in Benghazi city. In addition, we investigate the association between consanguinity and hearing and speech problems. A 699 of married couples who had 4248 offspring were randomly selected and interviewed to fill a questionnaire which was carefully designed. All the data was analysed using frequency distribution to determine percentages of consanguinity with different degree, and chi square test to compare consanguineous with non-consanguineous marriage. The prevalence of consanguinity in Benghazi was found to be 46% with a mean inbreeding coefficient of 0.0254. First cousin was the most common 40% type of consanguineous marriages. Deafness- dumbness, dumbness other hearing and speech Impairments were higher in offspring of first cousin than non-consanguineous marriage. Males have more deafness-dumbness, deafness than females, whereas females have more hearing and speech impairments than males. Genetic counselling is needed for risk due to consanguinity and its association with hearing and speech problems in Benghazi city population.
