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.

听力损失与认知功能之间关系的性别差异。


目的 本研究旨在确定具有全国代表性的老年人样本中按性别划分的听力损失与认知功能之间的关联。方法 我们使用了全国健康和营养检查调查（2010-2011 年）的数据，调查对象为 655 名 60 至 69 岁的参与者。认知功能部分包括建立阿尔茨海默氏病登记联盟、动物流畅性测试和数字符号替换测试。我们创建了一个综合 z 分数来表示全局认知功能。回归模型用于检查听力损失和认知功能之间的关联。结果 中度/重度听力损失与男性较低的综合 z 得分显着相关（β = -28.67，95% 置信区间 [95% CI] = -57.13 至 -0.20），但在女性中则不然（β = -8.82，95%） CI = -36.61 至 18.96）。结论 听力损失与认知功能之间的关联存在性别差异。未来的研究需要调查这些特定性别的关联。
