Subjective Hearing Difficulty and Fall Risk

Abstract

Purpose Hearing loss is a risk factor for falls. The purpose of this study was to investigate the relation between subjective hearing difficulty and risk of falls. Method Community-dwelling older adults, aged 60 years and older, completed a case history; three questionnaires, including the Hearing Handicap Inventory for the Elderly (HHIE), Dizziness Handicap Inventory (DHI), Activities-Specific Balance Confidence Scale (ABC); and one functional balance measure, the Timed Up and Go (TUG) test. Pearson and Spearman correlations were calculated, and average scores were plotted according to group and HHIE score category for DHI, ABC, TUG, the number of medications, and the number of recent falls. Results Seventy-four participants were included in this analysis: 28 nonaudiology patients, 18 audiology patients with hearing aids, and 28 audiology patients without hearing aids. Significant positive correlations were noted between HHIE and DHI scores for audiology patients without hearing aids and between HHIE score and number of recent falls for audiology patients with hearing aids. When average scores were plotted for DHI, ABC, TUG, the number of medications, and the number of recent falls according to group and category, there were clear trends toward increased fall risk as HHIE score categories increased (i.e., mild to moderate to severe) based on previously used criteria. Conclusions Overall, a trend was noticed such that, for increasing HHIE score categories, fall risk increased. Significant correlations existed between HHIE score and some of the measures used to indicate fall risk (i.e., DHI score, number of recent falls). Future fall risk research should investigate subjective hearing difficulty as a risk factor, as well as pure-tone audiometric thresholds.
