Objective
To investigate the impact of hearing aid and cochlear implant use on loneliness in adults
Study Design
Prospective observational cohort study
Methods
113 adults aged ≥50 years with post-lingual hearing loss receiving routine clinical care at a tertiary academic medical center were evaluated with the UCLA Loneliness Scale before and 6 and 12 months after intervention with hearing aids or cochlear implants. Change in score was assessed using linear mixed effect models adjusted for age, gender, education, and history of hypertension, diabetes, and smoking.
Results
Significant improvements in loneliness scores were observed in cochlear implant users from baseline to 6 months (−3.79 [95% confidence interval (CI): −5.73, −1.85], P <.001) and baseline to 12 months (−3.26 [95% CI: −5.66, −0.87], P =.007). We did not observe a significant improvement in loneliness scores in hearing aid users from baseline to 6 months (−0.83 [95% CI: −2.68, 1.02], P =.381) or baseline to 12 months (−0.34 [95% CI: −2.77, −2.10], P =.007).The most substantial increases were observed in individuals with the lowest baseline scores.
Conclusions
Treatment of hearing loss with cochlear implants results in a significant reduction in loneliness symptoms. This improvement was not observed with hearing aids. We observed differential effects of treatment depending on the baseline loneliness score with the greatest improvements observed in individuals with the most loneliness symptoms at baseline.
