Abstract:
The result of a study of prevalence, type and degrees Of hearing impairment in newborns and infants:Introduction: Significant bilateral hearing loss is the most common congenital disorder of the newborn, occurring 2-3 times per 1000 live infants. In December 2012, for the first time in Mongolia, neonatal hearing screening was introduced at the National Center for Maternal and Child Health. We aimed at investigated the outcomes of neonatal hearing screening and diagnostics of type and degree of hearing loss in neonates and infants.
Materials and methods: During the study period, 2019-2020, a total of 70,614 infants born in Urguu, Khuree, Amgalan maternity hospitals, Baganuur district health center, Intermed hospital, and the National Center for Maternal and Child Health were included in the prospective cohort study. The study was performed in three phases, following the clinical guidelines for neonatal hearing screening.
Results from the well-baby newborn hearing screening program and diagnostic follow-up of referred children from 2019 to 2021 were included in calculating prevalence rates. Hearing loss was classified according to the degree and type.
Results: A total of 94.1% of 70,614 children eligible for screening were included. A prevalence rate of bilateral hearing loss 2.23 per 1000 children was found. A prevalence rate of bilateral severe and profound hearing loss 1 per 1000 children was found. The mild sensorineural hearing loss 28 (26.0%) was most common in children, followed by moderate 19 (17,6%), severe 21 (19.4%), profound 19 (17.6%) and deaf 21 (19.4%).
Conclusions: The coverage of hearing screening in maternity hospitals in Ulaanbaatar is relatively good (94.1%), but there is a repeat screening (62.1%) and follow-up and diagnostic tests (49.9%). shows that the system needs to be improved. Because of the well-by hearing screening program, reported results approximate prevalence rates of permanent hearing loss by severity.
