A practical screening model for hearing loss in Iranian school-aged children

Area of Science:

• Pediatric Audiology
• Public Health
• Epidemiology

Background:

• Hearing loss significantly impacts school children's educational performance in developing nations.
• A practical, systematic school-based hearing screening protocol is lacking.
• This study addresses the need for an accessible screening model in Iran.

Purpose of the Study:

• To establish a practical, community-based screening model for hearing loss in school-aged children.
• To identify key indicators for hearing impairment in primary school students.

Main Methods:

• A retrospective case-control study involving 785 primary school children in Ilam, Iran.
• Utilized both non-audiologic (medical history, physical exam) and audiologic (otoscopy, audiometry, tympanometry) evaluations.
• Analyzed data for associations between hearing loss and demographic/clinical factors.

Main Results:

• Hearing loss was significantly associated with male gender and lower grade levels (first grade higher than second).
• Otitis media with effusion (OME) was a significant audiologic factor linked to impaired hearing.
• Univariate analysis revealed statistically significant correlations (P<0.05).

Conclusions:

• Routine hearing screening focused on identifying OME can effectively detect many hearing-impaired school children.
• Implementing this model can improve early detection and intervention for hearing loss.
• The findings support the development of practical, school-entry hearing screening protocols.
