| 中文摘要 | Objective: Nap, as an important living habit, accounts for a large proportion of the Chinese elderly. Previous studies have proved that nap affect healthy and cognitive function in the elderly to varying degrees. Studies of napping in childhood and youth can significantly promote cognitive function, but there are still some different conclusions on the impact of napping habits in the middle-aged and elderly population. Recent studies suggest that the decline of cognitive function in the elderly needs to be traced back to the middle age, and the sleep structure in the middle age begins to change. Studies on relationship between long-term nap habits and cognitive function are fewer. Therefore, it is particularly important to track the study of nap patterns in the whole life cycle and explore how nap develops and changes over time. Due to the change of life rules after retirement and affecting cognitive function to a certain extent, this study investigated the relationship between nap habits and cognitive function in the middle-aged and elderly,and the relationship between the change of nap habits and cognitive function after retirement.Methods: 891 elderly people over 60 years old with normal cognitive function [mean age 69.8±6.8] were selected in 3 main urban areas of Beijing. Firstly, a self-made nap habit questionnaire was used to investigate the nap of the elderly in each period; Then, the cognitive function was measured by Montreal Cognitive Assessment(MoCA) and auditory word test, associative learning test and Wechsler mapping test of Neuropsychological Test Battery (NTB). According to whether nap at each stage, it is divided into nap group (389 person) / no nap group (502 person) at middle-age , nap group (677 person) / no nap group (214 person) at the elderly. The relationship between nap habits of each stage and cognitive function is compared. Then, they were divided into retirement group (835 person) / non retirement group (56 person) according to whether they retired or not. Whether there are differences in cognitive function in different retirement conditions was investigated. Finally, according to the change of nap habit after retirement, they were divided into keeping no nap group (170 person), keeping nap group (333 person), old-aged nap group (307 person), only middle-aged nap group ( old-age don't nap, 25 person) among the 835 retired people. Through the scores of each group in cognitive test, the relationship between the changes of afternoon nap habits and cognitive function after retirement was compared. The nap frequency of keeping nap group and old-aged nap group was seperately divided into low-frequency group and high-frequency group. The relationship between different nap frequency and cognitive function was compared by cognitive test.Results: 1) After controlling the covariate factors , the scores of associative learning in the nap group at middle-age were higher than the non nap group at the same stage(P=0.028), but at the elder stage ,compare the nap group and the non nap group ,it was no different significantly. Multivariate linear regression analysis showed that midlife nap significantly correlate with higher associative learning scores (β=0.566, P=0.024). 2) The scores of MoCA and associative learning in the retired group were higher than the non retired group (P=0.009, P=0.007). 3) After controlling the covariate factors in the retired group , the association learning score of the keeping nap group was higher than that of the old-age nap group [(7.8± 4.1) vs. (6.8± 3.9), P=0.040]. Multivariate linear regression analysis showed that the change of nap habits after retirement significantly correlate with lower associative learning scores (β=-0.32, P=0.028). 4) The scores of auditory words in the low-frequency group were higher than the high-frequency group in the old-aged nap group[(48.2 ± 11.2) vs. (42.8 ± 11.1), P=0.015]; Multivariate linear regression analysis showed that the high-frequency group after retirement significantly correlate with the lower score of associative learning(β=-3.016, P=0.030).Conclusion: Compared with middle-aged people without nap, people with nap have better episodic memory. The habit of keeping nap from the middle age to the old age is conducive to maintain the episodic memory in retirees. Among the people who take napping at the old age , low frequency nap is beneficial to the maintenance of episodic memory. There are significant difference in overall cognition and episodic memory between non retirees over 60 years old and retirees. It can be advocated as a positive and healthy lifestyle to develop and maintain a good habit of taking a nap in middle age. More attention should be paid to the elderly who are old, have a low level of education and start taking a nap after retirement. |
| 英文摘要 | 目的：午睡做为重要生活习惯，在中国老年人群中占有极大的比例。既往研究发现午睡不同程度地影响老年健康和认知功能。研究发现儿童期和青年期的午睡明显促进认知功能，但在中老年人群中，午睡习惯对认知功能的影响仍存在一些不同结论。最近研究提出，中年期睡眠结构开始发生变化，老年期认知功能的下降需要追溯到中年期。目前有关长期午睡习惯与认知功能关系的研究较少，因此追踪整个生命周期并探讨午睡如何随着时间推移而发展和变化尤为重要。由于退休后生活规律发生改变并在一定程度上影响认知功能，因此本研究考察了从中年期到老年期午睡习惯与认知功能关系，对比60岁以上退休与非退休人员的认知功能状况，以及退休后午睡习惯改变与认知功能关系。方法：在北京市3个主城区以方便取样选取891名60岁以上且认知功能正常的老年人[平均69.8±6.8岁]。首先，采用自编午睡习惯问卷调查老年人各时期的午睡情况，并采用蒙特利尔认知评估表(MoCA)和老年成套神经心理测验(NTB)的听觉词语测验、联想学习测验、韦氏填图测验测定认知功能。按照各阶段有无午睡，分为中年期午睡组(389人)/无午睡组(502人)、老年期午睡组(677人)/无午睡组(214人)，比较各阶段有无午睡与认知功能的关系。其次，根据是否退休，分为退休组(835人)/未退休组(56人)，考察不同退休状况是否存在认知功能差异。最后，在已退休的835人中，根据退休后午睡习惯是否变化分为持续无午睡组(170人)、持续午睡组(333人)、老年起午睡组(307人)、仅中年午睡组(老年期不午睡，25人)，通过各组认知测验的得分，比较退休后午睡习惯变化与认知功能的关系。将持续午睡组和老年起午睡组的午睡频率分为低频组和高频组，分别通过认知测验比较不同午睡频率与认知功能的关系。结果：1)控制各协变量后，中年期午睡组联想学习得分高于中年期无午睡组(P=0.028)，老年期午睡组/无午睡组在各认知测验得分上没有显著差异；多因素线性回归分析显示：中年期午睡习惯与联想学习得分显著相关(β=0.566, P=0.024)。2)退休组MoCA、联想学习的得分高于未退休组(P=0.009,P=0.007)。3)控制各协变量后，退休人员中持续午睡组的联想学习得分高于老年起午睡组[(7.8± 4.1)vs.( 6.8± 3.9), P=0.040]；多因素线性回归分析显示：退休后午睡习惯改变与联想学习较低得分相关(β=-0.32, P=0.028)。4)老年起午睡组中，低频组听觉词语得分高于高频组[(48.2±11.2)vs.(42.8±11.1),P=0.015]；多因素线性回归分析显示：老年期开始午睡人群中高频率午睡与低听觉词语得分高相关(β=-3.016,P=0.030)。结论：中年期午睡有益于情节记忆；从中年开始持续到老年的午睡习惯有利于退休后情节记忆的保持；老年期开始午睡人群以低频午睡有益于情节记忆保持；60岁后未退休人员与退休人员整体认知功能和情节记忆存在明显差异。中年时期养成良好午睡习惯并持续保持可以做为一项积极健康生活方式加以倡导，另外对高龄、受教育程度低、退休后开始午睡老年人群需更多关注。 |
