Abstract

Background: The Aging and Cognitive Health Evaluation in Elders (ACHIEVE) Study was designed to determine the effects of a best-practice hearing intervention on cognitive decline among community-dwelling older adults. Here, we conducted a secondary analysis of the ACHIEVE Study to investigate the effect of hearing intervention on self-reported communicative function. Methods: The ACHIEVE Study is a parallel-group, unmasked, randomized controlled trial of adults aged 70–84 years with untreated mild-to-moderate hearing loss and without substantial cognitive impairment. Participants were randomly assigned (1:1) to a hearing intervention (audiological counseling and provision of hearing aids) or a control intervention of health education (individual sessions with a health educator covering topics on chronic disease prevention) and followed semiannually for 3 years. Self-reported communicative function was measured with the Hearing Handicap Inventory—Elderly Screening version (HHIE-S, range 0–40, higher scores indicate greater impairment). Effect of hearing intervention versus control on HHIE-S was analyzed through an intention-to-treat model controlling for known covariates. Results: HHIE-S improved after 6-months with hearing intervention compared to control, and continued to be better through 3-year follow-up. We estimated a difference of −8.9 (95% CI: −10.4, −7.5) points between intervention and control groups in change in HHIE-S score from baseline to 6 months, −9.3 (95% CI: −10.8, −7.9) to Year 1, −8.4 (95% CI: −9.8, −6.9) to Year 2, and − 9.5 (95% CI: −11.0, −8.0) to Year 3. Other prespecified sensitivity analyses that varied analytical parameters did not change the observed results. Conclusions: Hearing intervention improved self-reported communicative function compared to a control intervention within 6 months and with effects sustained through 3 years. These findings suggest that clinical recommendations for older adults with hearing loss should encourage hearing intervention that could benefit communicative function and potentially have positive downstream effects on other aspects of health.
