Abstract

Introduction: Sleep duration is proposed as a lifestyle-related risk factor for cognitive impairment. We investigated the association between sleep duration and cognitive function in a large population-based cohort aged 62-65 years.

Methods: Cross-sectional analyses from the Akershus Cardiac Examination 1950 Study. Linear and nonlinear models were conducted to explore the association between self-reported sleep duration and cognitive function, adjusted for established risk factors for cognitive impairment.

Results: We included 3,348 participants, mean age (SD) was 63.9 ± 0.6 years, 48.2% were women, and 47.9% had education >12 years. Mean sleep duration (SD) was 7.0 ± 1.0 h, and 10.2% had abnormal sleep duration (<6 or >8 h). Individuals reporting <6 h or >8 h of sleep scored significantly lower on MoCA test and delayed recall trial in adjusted analysis.

Conclusions: Sleep duration showed an inverted U-shaped association with global cognitive function and memory, suggesting that both shortened and prolonged sleep are related to adverse brain health.

睡眠时间与认知功能，1950 年阿克苏斯心脏检查研究。

简介睡眠时间被认为是导致认知障碍的一个与生活方式相关的风险因素。我们在 62-65 岁的大型人群中调查了睡眠时间与认知功能之间的关系：方法：对 1950 年阿克苏斯心脏检查研究进行横断面分析。采用线性和非线性模型探讨自我报告的睡眠时间与认知功能之间的关系，并对认知障碍的既定风险因素进行调整：我们共纳入了 3348 名参与者，平均年龄（标清）为 63.9 ±0.6 岁，48.2% 为女性，47.9% 受过 12 年教育。平均睡眠时间（标准差）为 7.0±1.0 小时，10.2% 的人睡眠时间不正常（6 小时或 8 小时）。在调整分析中，睡眠时间为6小时或8小时的人在MoCA测试和延迟回忆试验中的得分明显较低：睡眠时间与整体认知功能和记忆力呈倒 "U "型关系，表明睡眠时间过短和过长都会对大脑健康造成不良影响。

期刊介绍： As a unique forum devoted exclusively to the study of cognitive dysfunction, ''Dementia and Geriatric Cognitive Disorders'' concentrates on Alzheimer’s and Parkinson’s disease, Huntington’s chorea and other neurodegenerative diseases. The journal draws from diverse related research disciplines such as psychogeriatrics, neuropsychology, clinical neurology, morphology, physiology, genetic molecular biology, pathology, biochemistry, immunology, pharmacology and pharmaceutics. Strong emphasis is placed on the publication of research findings from animal studies which are complemented by clinical and therapeutic experience to give an overall appreciation of the field.
