ABSTRACT
OBJECTIVES: The main objective of this study is to identify the prevalence of hearing loss in school aged children of Nepal.
METHODS: This cross-sectional study was carried out on school aged children attending the government run schools of Nepal. A total of 79,340 children from grades 1 through 10 were included in the study. After taking brief history about ear diseases and hearing loss, children were screened for ear diseases in their respective classroom by otoscope. Hearing evaluation was carried out by pure tone audiometer and hearing threshold was obtained at 0.5-4 kHz. The results were then documented and analyzed.
RESULTS: The prevalence of hearing impairment in school aged children in Nepal is found to be 5.73% (4551 of 79,340). Conductive hearing loss was the most common type of hearing loss and was o bserved in 70.47% (n = 3207) of the children.
CONCLUSIONS: This study shows that hearing loss is a common problem in children of Nepal. With the main cause of hearing loss due to preventable conditions such as chronic otitis media, it is believed that early standardized screening, detection and timely management of chronic otitis media in these children can prevent hearing loss and its impact on their educational, social and language development. School based ear health programs are a useful community-oriented solution for prevention of deafness. It shows how important it is to introduce hearing screening for primary school aged children to prevent hearing loss.
