Background: Today, hearing loss in children is widely recognized as a public health issue. The goal of this study was to identify the prevalence, distribution and types of hearing loss among children aged 2-5 in a sample of kindergartens in Hai Duong Province, Vietnam, in 2018.
Methods: A cross-sectional study was conducted among children aged 2-5 years old at 4 kindergartens in Hai Duong Province, Vietnam. This study included the following three steps: a two-step otoacoustic emission (OAE) program, completed by an auditory brainstem response (ABR) for the positive diagnosis of hearing impairment.
Results: The subjects of the study were 1,090 children aged 2-5 years old who underwent hearing screening at kindergartens in Hai Duong Province, Vietnam. The percentage of children with true hearing loss was 4.7%, confirmed by ABR. The majority of the hearing loss in the children was conductive hearing loss (74.5%). Mild hearing loss (21-40 dB) accounted for nearly half of the children with hearing loss (49.0%).
Conclusion: The study found that hearing loss is common among preschool children in Vietnam. Routine hearing screening of school-aged children should be included in annual school health programs in Vietnam.
