Prevalence and factors associated with hearing loss and hearing aid use in korean elders.

Kim JS - Iran. J. Public Health (2015)

Bottom Line: Hearing loss was found in 16.8% of the elders and only 15.9% of them used a hearing aid.Tinnitus (95% CI: 1.34-4.13) and occupational noise exposure (95% CI: 1.01-5.02) were strongly associated with hearing aid use after multivariate adjustment.An aural public health program should address modifiable risk factors, such as tinnitus and noise exposure, and non-modifiable risk factors associated with hearing loss in the elderly.

ABSTRACT

Background: This study examined hearing loss prevalence and hearing aid usage rates among Korean elders by comparing the differences between those with and without hearing loss, and between those who used and did not use hearing aids.

Methods: This study was based on data collected during the Korean National Health and Nutrition Examination Survey V (2010-2012). The study sample consisted of 5,447 Koreans aged ≥60 years who received a hearing assessment. Hearing loss was measured using a pure tone audiometry test and classified according to the World Health Organization's criteria. Hearing aid use was assessed by self-report. Multiple logistic regression analyses were performed to determine the associations between hearing loss, hearing aid use, and related variables.

Results: Hearing loss was found in 16.8% of the elders and only 15.9% of them used a hearing aid. Male (95% CI: 1.27-2.15), tinnitus (95% CI: 1.58-2.32), dizziness (95% CI: 1.05-1.73), and occupational noise exposure (95% CI: 1.32-2.38) were the variables most strongly associated with hearing loss after multivariate adjustment. Tinnitus (95% CI: 1.34-4.13) and occupational noise exposure (95% CI: 1.01-5.02) were strongly associated with hearing aid use after multivariate adjustment.

Conclusion: More than half of South Korean elders aged ≥60 and older have hearing loss but the rate of hearing aid use is very low. An aural public health program should address modifiable risk factors, such as tinnitus and noise exposure, and non-modifiable risk factors associated with hearing loss in the elderly.

Figure 1: Hearing loss and hearing aid use by age group (n = 5,447)

Mentions: Hearing loss (in the better ear) in people aged 60 and older was mild (32.4%), moderate (15.0%), and severe (1.8%). The rate of hearing aid use for overall hearing loss cases (in the better ear with 25 dB) was only 5.3%, and 15.9% for moderate or more serious hearing loss (in the better ear with 40 dB) (Table 1). Hearing loss tended to rise rapidly with age, with 6.5% of the 60–64 age group exhibiting hearing loss compared to 46.0% in the 80 and older age group. The 60–64 age group showed the highest rate of hearing aid use (16.5%) but it was low given the overall prevalence of hearing loss (Fig. 1). When the actual hearing test outcomes were compared with the subjective assessments of hearing status, 37.6% of those who claimed not to have a hearing problem had mild to severe hearing loss; and 14.5% of those who answered, “Can’t hear at all,” had normal hearing (Fig. 2).
