Main Article Content


A cross-sectional descriptive study was conducted on a group of 461 hearing impaired children who were diagnosed and treated at the Audiology and Speech language therapy centre at the National Children Hospital from January 2018 to August 2019. The purpose of the study is to assess the distribution of children by age group, gender, degree of hearing loss, high risk factors of hearing loss, and status of intervention in this group of children. Data were taken by using questionnaires and analyzed using Stata software. The results showed in the study group, there were 281 boys and 180 girls. Children with profound hearing loss have the highest rate with 58.4%, followed by the severe (11,9%) and the moderate to severe (6,9%). ANSD accounts for 16.7%. The majority of children with hearing loss in both ears (90,5%), only 9,5% children with hearing loss in one ear. The most common age at which children with hearing loss are detected is 13-24 months (33,2%). Among ANSD children, 73,6% had a history of jaundice in the newborn period. Only 17,6% of children had hearing aids and 8,9% of children with severe to profound hearing loss had cochlear implants.
