Researchers at Wroclaw Medical University in Poland published findings from the PICTURE cohort study, a longitudinal population study of school-age children and their caregivers that ran from 2019 to 2023. The study examined the prevalence of hearing loss and tinnitus in children and assessed how well parental reports aligned with clinical screening results from otoacoustic emission (OAE) testing.
The study found a hearing loss prevalence of 2.7% as measured by pure-tone audiometry. Younger children showed higher rates of abnormal OAE results, which the researchers attributed in part to greater susceptibility to ear infections and middle ear dysfunction at younger ages. Parental subjective assessments did not consistently match OAE results, pointing to the limitations of relying on caregiver observation alone for early detection.
