Studies of sleep duration in relation to the risk of sensory impairments other than dementia are scarce. Little is known about the associations between sleep duration and sensory impairments in China. This study aims to explore the associations between sleep duration and single or dual sensory impairments (visual and/or hearing).
This cross-sectional study used the data from 17,668 respondents were drawn from the 2018 survey of the China Health and Retirement Longitudinal Study (CHARLS), an ongoing national longitudinal study of Chinese adults aged 45 years and above. The duration of sleep per night was obtained from face-to-face interviews. The presence of sensory impairments was measured by self-reported visual and hearing functions. Multivariable generalized linear models (GLM) with binomial family and log link to assess the associations between sleep duration and sensory impairments.
Of the 17,668 respondents, 8,396 (47.5%) were men. The mean () age was 62.5 (10.0) years old. Respondents with short (≤ 4, 5 h per night) sleep duration had a significantly higher risk of visual, hearing and dual sensory impairments than those who slept for 7 h per night after adjusting for covariates ( < 0.05). Meanwhile, respondents who slept for 6 h per night had a higher risk of hearing impairment ( = 0.005). Further analysis suggested a U-shaped association between sleep duration and sensory impairments. When sleep duration fell below 8 h, increased sleep duration was associated with a significantly lower risk of visual (OR, 0.93; 95%CI, 0.88-0.98; = 0.006), hearing (OR, 0.89; 95% CI, 0.86-0.93; < 0.001), and dual (OR, 0.90; 95% CI, 0.87-0.94; < 0.001) impairments. When sleep duration exceeded 8 h, the risk of visual (OR, 1.09; 95% CI, 1.00-1.19; = 0.048), hearing (OR, 1.04; 95% CI, 0.97-1.11; = 0.269), and dual (OR, 1.07; 95% CI, 1.00-1.14; = 0.044) impairments would increase facing prolonged sleep duration. Women and the elderly aged over 60 years old were more sensitive to short sleep duration and experienced a higher risk of sensory impairments.
In this study, short sleep duration was associated with a higher risk of visual and hearing impairments. Future studies are needed to examine the mechanisms of the associations between sleep duration and sensory impairments.
关于睡眠时间与除痴呆症以外的感觉障碍风险的研究很少。在中国，关于睡眠时间与感觉障碍之间的关联知之甚少。本研究旨在探讨睡眠时间与单一或双重感觉障碍（视觉和/或听力）之间的关联。
这项横断面研究使用了来自中国健康与养老追踪调查（CHARLS）2018年调查的17668名受访者的数据，CHARLS是一项针对45岁及以上中国成年人的正在进行的全国性纵向研究。每晚睡眠时间通过面对面访谈获得。感觉障碍的存在通过自我报告的视觉和听力功能来衡量。采用二项式族和对数链接的多变量广义线性模型（GLM）来评估睡眠时间与感觉障碍之间的关联。
在17668名受访者中，8396名（47.5%）为男性。平均（）年龄为62.5（10.0）岁。在调整协变量后（<0.05），睡眠时间短（每晚≤4、5小时）的受访者出现视觉、听力和双重感觉障碍的风险显著高于每晚睡7小时的受访者。同时，每晚睡6小时的受访者出现听力障碍的风险更高（=0.005）。进一步分析表明睡眠时间与感觉障碍之间呈U形关联。当睡眠时间低于8小时时，睡眠时间增加与视觉（OR，0.93；95%CI，0.88 - 0.98；=0.006）、听力（OR，0.89；95%CI，0.86 - 0.93；<0.001）和双重（OR，0.90；95%CI，0.87 - 0.94；<0.001）障碍的风险显著降低相关。当睡眠时间超过8小时时，视觉（OR，1.09；95%CI，1.00 - 1.19；=0.048）、听力（OR，1.04；95%CI，0.97 - 1.11；=0.269）和双重（OR，1.07；95%CI，1.00 - 1.14；=0.044）障碍的风险会随着睡眠时间延长而增加。女性和60岁以上的老年人对短睡眠时间更敏感，感觉障碍的风险更高。
在本研究中，短睡眠时间与更高的视觉和听力障碍风险相关。未来需要研究来探讨睡眠时间与感觉障碍之间关联的机制。
