Hearing Loss and Physical Functioning Among Adults with Heart Failure: Data from NHANES.

Background: Hearing loss (HL) is associated with poor physical functioning among older adults, yet this association has not been examined in heart failure (HF), a disease in which both hearing loss and poor physical functioning are highly prevalent. We investigated whether this association exists in HF since HL represents a potentially modifiable risk factor for poor physical functioning. Methods: We studied adults aged ≥70 years with self-reported HF in the National Health and Nutrition Examination Survey (NHANES). HL was assessed and categorized using pure-tone averages. Activities of daily living (ADLs), instrumental ADLs (IADLs), leisure and social activities (LSA), lower extremity mobility (LEM), and general physical activity (GPA) were assessed. Negative binomial regression was used to examine the association between HL and physical functioning Results: One hundred eighty-one participants comprised our population. Those with ≥ moderate HL had more difficulty with ADLs (37.0% vs 24.0%, p=0.02), IADLs (36.0% vs 23.0%, p=0.05), and LEM (37.3% vs 20.0%, p=0.009), compared to participants with none or mild HL. In multivariable models, ≥ moderate HL was significantly associated with difficulty in physical functioning across four of the five domains: ADLs: PR: 1.71 (95% CI: 1.07-2.72); IADLs: PR: 1.71 (1.24-2.34); LEM: PR: 1.51 (1.01-2.26); and GPA: PR: 1.19 (1.00-1.41). Conclusion: Among older adults with HF, moderate or greater HL was associated with a higher prevalence of difficulty with ADLs, IADLs, and LEM, compared to mild or no HL.
