Population-based evidence linking sleep characteristics with hearing is limited and how the associations change with age remains unknown. We aim to investigate cross-sectional associations between sleep characteristics and hearing by age in a nationally representative sample of U.S. adults.
We included 3,100 participants aged 40 years and older from the National Health and Nutrition Examination Survey 2015-18. Audiometric hearing thresholds at 0.5, 1, 2 and 4 kilohertz were averaged to calculate better-ear pure-tone average (PTA). Sleep questions were self-reported, including sleep duration on weekdays or workdays, snoring, snorting or stopping breathing, trouble sleeping, and daytime sleepiness. Multivariable-adjusted linear regression with an interaction term between sleep characteristic (categorical) and age (continuous in years) was used. Primary models adjusted for demographic and lifestyle factors with additional adjustment for cardiovascular factors in secondary models.
There was no association of reported sleep duration with PTA at age 50; however, compared to those reporting 7-8 h of sleep, there was a borderline-significant association at age 60 (<7 h: 1.72 dB, 95 % confidence interval [CI], -0.21, 3.66; >8 h: 1.25 dB, 95 % CI, -0.01, 2.51), and a significant association at age 70 (<7 h: 2.52 dB, 95 % CI, -0.27, 5.31; >8 h: 2.67 dB, 95 % CI, 0.56, 4.79). No consistent associations for other sleep characteristics were found.
Long sleep duration is associated with worse hearing among middle-aged and older adults and the association differs by age. Longitudinal evidence is needed to establish temporality and examine changes in hearing associated with sleep characteristics.
基于人群的将睡眠特征与听力联系起来的证据有限，且这些关联如何随年龄变化仍不清楚。我们旨在在美国成年人的全国代表性样本中，按年龄调查睡眠特征与听力之间的横断面关联。
我们纳入了2015 - 2018年国家健康与营养检查调查中3100名40岁及以上的参与者。对0.5、1、2和4千赫兹的听力阈值进行平均，以计算较好耳的纯音平均听阈（PTA）。睡眠问题通过自我报告，包括工作日或工作日的睡眠时间、打鼾、哼声或呼吸停止、睡眠困难和日间嗜睡。使用了睡眠特征（分类变量）与年龄（以年为连续变量）之间带有交互项的多变量调整线性回归。主要模型对人口统计学和生活方式因素进行了调整，次要模型对心血管因素进行了额外调整。
50岁时报告的睡眠时间与PTA无关联；然而，与报告睡眠7 - 8小时的人相比，60岁时有边缘显著关联（<7小时：1.72分贝，95%置信区间[CI]，-0.21，3.66；>8小时：1.25分贝，95% CI，-0.01，2.51），70岁时有显著关联（<7小时：2.52分贝，95% CI，-0.27，5.31；>8小时：2.67分贝，95% CI，0.56，4.79）。未发现其他睡眠特征有一致的关联。
睡眠时间长与中老年人群听力较差有关，且这种关联因年龄而异。需要纵向证据来确定时间顺序，并研究与睡眠特征相关的听力变化。
