Sensorineural hearing loss among children at risk: A 16-year audiological records review in a tertiary referral center

Abstract

ObjectivesHearing loss (HL) constitutes an increasing worldwide health problem. Neonatal hearing screening improved early detection and management to alleviate HL detriments on the person and society. Still, HL in childhood, beyond infancy, is under-investigated, especially in developing countries. This study aimed to explore the prevalence of HL in childhood amongst Jordanian children with HL risk factors and investigate the associated risk factors. MethodsRetrospective cross-sectional review of audiological records in a tertiary public and teaching hospital. The data of 1307 children aged 0–15 years who underwent audiological assessment from 2000 to 2016 were included. A review of diagnostic audiological and medical records was conducted to investigate the prevalence of sensorineural HL in high-risk (HR) children and the most contributing risk factors. ResultsDescriptive statistical analysis showed that the prevalence of sensorineural HL was 29.2% in the study sample. The HL was bilateral in 95% and mild to moderate HL in 73%. The mean age at the diagnosis was around 4.5 years. The most common risk factors were parental concern about their child's hearing, ototoxic drug use, and developmental and speech delay. The Chi-squared test showed that parental concern and ototoxic drug use were associated with an increased probability of having HL. ConclusionThe prevalence of HL amongst at-risk children in Jordan is relatively high, and the diagnosis is delayed. The results highlight the importance of implementing a hearing screening program in at-risk children. This needs to start from birth and include a serial follow-up to detect cases of delayed-onset HL.
