Abstract
Objective
The overall objective in the study was to compare self-reported hearing based on a single question (“how good would you currently rate your hearing?”) to measure hearing loss determined by audiometry in a cohort of adolescents. Prevalence of audiometrically measured hearing loss and frequencies of self-reported poor hearing as well as factors that have an impact on self-reported hearing were examined.
Design
Baseline and 5-year follow-up data of the Ohrkan study were used. Participants filled in a questionnaire and underwent audiometric measurements.
Study sample
Data from 979 adolescents were analysed. Participants were 54.7% female and aged between 13 and 18 years at baseline and 17–21 years at 5-yr follow-up.
Results
The single question on self-reported hearing ability achieved a sensitivity of 41.9% and a positive predictive value of 7.1% at baseline. For the 5-yr follow-up, sensitivity was 40.0%, positive predictive value was 13.9%. Factors influencing self-reported poor hearing were gender, tinnitus, “muffled” ears after exposure to loud noise (e.g. after a concert) and low-frequency hearing loss.
Conclusions
The single question about hearing ability used in the Ohrkan study is not sufficient to replace audiometry to detect hearing loss as defined in the study in adolescents.
