Objective:This study aimed to determine the association between hearing loss and cognitive function by gender in a nationally representative sample of older adults.Methods:We used data from the National Health and Nutrition Examination Survey (2010-2011) for 655 participants aged 60 to 69 years. The cognitive functioning component consisted of the Consortium to Establish a Registry for Alzheimer’s disease, the Animal Fluency Test, and the Digit Symbol Substitution Test. We created a composite z score to represent global cognitive function. Regression models were used to examine the association between hearing loss and cognitive function.Results:Moderate/severe hearing loss was significantly associated with lower composite z score in males (β = −28.67, 95% confidence interval [95% CI] = −57.13 to −0.20) but not in females (β = −8.82, 95% CI = −36.61 to 18.96).Conclusion:There were gender differences in the association between hearing loss and cognitive function. Future studies need to investigate these gender-specific associations.
