Abstract

Objectives: To analyze the association between neurocognitive performance and age-related hearing loss in the right and left ear, individually. Design: Subjects included 5277 participants (≥50 years) from the general Hispanic population who underwent audiometric testing in a US multicentered epidemiologic study. Linear regression was performed to assess the cross-sectional association between cognitive performance (Digit Symbol Substitution Test [DSST], Word Frequency Test, Spanish-English Verbal Learning Test [SEVLT] 3 Trials, SEVLT Recall, and Six-Item Screener) and hearing in each ear (4-frequency pure-tone average), adjusting for age, sex, education, cardiovascular disease, and hearing aid use. Results: Mean age was 58.4 ± 6.2 years; 3254 (61.7%) were women. Mean pure-tone averages were 20.2 ± 11.7 dB (right ear) and 20.2 ± 12.3 dB (left ear). Multivariable regression demonstrated significant associations between all cognitive tests and hearing loss in both ears. Conclusions: Worsening hearing loss in the right and left ear was associated with decreased performance across all tests. No laterality in the association was demonstrated.
