目的:评估退休后老年人的午睡习惯与老年认知功能的关系。方法:在北京市3个主城区选取835例老年人[平均年龄(69.8±6.8)岁],根据开始午睡的年龄阶段分为无午睡组(n=170)、中年午睡组(n=333)、老年午睡组(n=307)、习惯改变组(中年午睡但老年不午睡)(n=25)。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。结果:中年午睡组的联想学习得分高于老年午睡组(P

Objective: To evaluate the relationship between nap habit and cognitive function in the retired elderly. Methods: Totally 835 elderly people ［average age (69. 8 ± 6. 8) years］were selected from 3 main urban areas of Beijing. According to the age stage of starting nap，they were divided into 4 groups，namely no nap group，middle-aged nap group，old napping group and change group (middle-aged nap but not for the elderly) . The Montreal Cognitive Assessment (MoCA) and Neuropsychological Test Battery (NTB)，including auditory word test，associative learning test and Wechsler mapping test，were used to measure cognitive function. Ｒesults: The scores of association learning were higher in middle-aged nap group than in elderly nap group (P ＜ 0. 05) . Multivariate linear regression analysis showed that different nap habits of middle-aged and elderly nap groups negatively predicted the score of associative learning (β = － 0. 32) . Conclusion: It suggests that the people who start to take naps at the middle age are better at association learning than the people who start napping at the elderly age.
