Factors affecting hearing aid adoption by adults with high-frequency hearing loss: The beaver dam offspring study

Abstract

Purpose: Hearing loss (HL) is common among middle-age and older adults, but hearing aid adoption is low. The purpose of this study was to measure the 10-year incidence of hearing aid adoption in a sample of primarily middle-age adults with high-frequency HL and identify factors associated with hearing aid adoption. Method: This study included 579 adults (ages 34–80 years) with high-frequency pure-tone average > 25 dB HL (3–8 kHz) enrolled in the Beaver Dam Offspring Study. Hearing aid adoption was measured at 5-and 10-year follow-up examinations. Cox discrete-time proportional hazards models were used to evaluate factors associated with hearing aid adoption (presented as hazards ratios [HRs] and 95% confidence intervals [95% CI]). Results: The 10-year cumulative incidence of hearing aid adoption was 14 per 1,000 person years. Factors significantly associated with adoption in a multivariable model were higher education (vs. 16+ years; 0–12: HR: 0.36, 95% CI [0.19, 0.69]; 13–15: HR: 0.52, 95% CI [0.27, 0.98]), worse high-frequency pure-tone average (per +1 dB; HR: 1.04, 95% CI [1.02, 1.06]), self-reported hearing handicap (screening versions of the Hearing Handicap Inventory score > 8; HR: 1.85, 95% CI [1.02, 3.38]), answering yes to “Do friends and relatives think you have a hearing problem?” (HR: 3.18, 95% CI [1.60, 6.33]) and using closed captions (HR: 2.86, 95% CI [1.08, 7.57]). Effects of age and sex were not significant. Conclusions: Hearing aid adoption rates were low.
