This study examined the association between hearing loss and impaired lower extremity function, frailty syndrome, and disability in older adults. It found a strong correlation between hearing loss and these functional impairments.
IMPORTANCE Several studies have examined the association between hearing loss (HL) and physical function, with inconsistent results. Few used pure-tone thresholds and considered possible confounders in the association. OBJECTIVE To examine the association between hearing loss and impaired lower extremity function, frailty syndrome, and disability in older adults. DESIGN, SETTING, AND PARTICIPANTS The Seniors-ENRICA-2 is a cohort study thatwas established in 2015-2017 in Spain. The present study was conducted from December 2015 to June 2017. Data were analyzed from January 2, 2021, to March 10, 2021. This cross-sectional analysis included 1644 community-dwelling individuals aged 65 years or older (range, 66-91 years) of both sexes. Participants had hearing threshold measurements and data on impaired lower extremity function, frailty syndrome, and disability. EXPOSURES Hearing loss defined as pure-tone average greater than 40 dB HL in the better ear for standard frequency (0.5, 1, and 2 kHz), speech frequency (0.5, 1, 2, and 4 kHz), and high frequency (3, 4, and 8 kHz). MAIN OUTCOMES AND MEASURES Impaired lower extremity functionwas defined with the Short Physical Performance Battery; the frailty syndrome was defined as having at least 3 of the 5 criteria, including weakness, slow walking speed, low physical activity, exhaustion, and weight loss; and disability in instrumental activities of daily living (IADL) was evaluated with the Lawton and Brody scale. RESULTS Of the 1644 participants, 831 were men (50.5%); mean (SD) age was 73.8 (4.3) years. The prevalence of moderate HL was 13.6% at speech frequency. After adjustment for age, sex, lifestyle, comorbidities, impaired cognition, and social isolation, HL in standard frequency was associated with impaired lower extremity function, with an odds ratio (OR) of 2.20 (95% CI, 1.25-3.88); the corresponding estimate for the frailty syndrome was 1.85 (95% CI, 0.98-3.49) and for the IADL disability, was 2.25 (95% CI, 1.29-3.94). When considering speech frequency pure-tone average, HL was also associated with impaired function (OR, 2.59; 95% CI, 1.57-4.28), frailty syndrome (OR, 1.85; 95% CI, 1.06-3.22), and IADL disability (OR, 2.18; 95% CI, 1.32-3.60). CONCLUSIONS AND RELEVANCE In this cross-sectional analysis of data from the Seniors-ENRICA-2 cohort study, hearing loss was associated with impaired lower extremity function, frailty syndrome, and IADL disability. It may be useful to examine this association with the mechanisms elucidated in further studies.
