Objective
We estimate the prevalence of hearing-aid use in Iceland and identify
sex-specific factors associated with use.
Design
Population-based cohort study.
Study sample
A total of 5172 age, gene/environment susceptibility - Reykjavik
study (AGES-RS) participants, aged 67 to 96 years (mean age 76.5 years), who
completed air-conduction and pure-tone audiometry.
Results
Hearing-aid use was reported by 23.0% of men and
15.9% of women in the cohort, although among participants with at
least moderate hearing loss in the better ear (pure-tone average [PTA] of
thresholds at 0.5, 1, 2, and 4 kHz ≥ 35 dB hearing level [HL]) it
was 49.9% and did not differ by sex. Self-reported hearing loss was
the strongest predictor of hearing-aid use in men [OR: 2.68 (95% CI:
1.77, 4.08)] and women [OR: 3.07 (95% CI: 1.94, 4.86)], followed by
hearing loss severity based on audiometry. Having diabetes or osteoarthritis
were significant positive predictors of use in men, whereas greater physical
activity and unimpaired cognitive status were important in women.
Conclusions
Hearing-aid use was comparable in Icelandic men and women with
moderate or greater hearing loss. Self-recognition of hearing loss was the
factor most predictive of hearing-aid use; other influential factors
differed for men and women.
