研究中国老年人自我报告的午餐后小睡与结构化认知评估之间的横断面关联。横断面队列研究。中国。中国健康与退休纵向研究 (CHARLS) 全国基线中 65 岁及以上的个人 (N = 2,974)。基于访谈的定向和注意力、情景记忆、视觉空间能力以及包含这些评估的综合整体认知评分的认知评估。其他自我报告或基于访谈的评估包括午餐后小睡时间、夜间睡眠时间、人口特征、健康习惯、合并症、功能状态和社交活动。根据报告的午睡时间，老年人被分为非午睡者（0分钟）、短午睡者（<30分钟）、中度午睡者（30-90分钟）和长时间午睡者（>90分钟）。 57.7% 的参与者表示午餐后小睡的时间平均为 63 分钟。认知功能与小睡显着相关 (P < .001)。组间比较显示，中度午睡者比不午睡者 (P < .001) 或长时间午睡者 (P = .01) 具有更好的整体认知能力。不打瞌睡的人的认知能力也显着低于打瞌睡时间短的人 (P = .03)。在多元回归分析中，在控制人口特征、体重指数、抑郁、日常生活工具性活动、社交活动和夜间睡眠持续时间后，适度小睡比不小睡（P = .004）、短小睡（P = .04）和长时间小睡（P = .002）与更好的认知显着相关。研究发现，中国老年人适度的午餐后小睡与更好的认知能力之间存在横断面关联。横断面设计和自我报告的睡眠测量结果限制了研究结果。需要进行客观午睡措施的纵向研究来进一步检验这一假设。
To examine the cross-sectional associations between self-reported postlunch napping and structured cognitive assessments in Chinese older adults. Cross-sectional cohort study. China. Individuals aged 65 and older from the baseline national wave of the China Health and Retirement Longitudinal Study (CHARLS) (N = 2,974). Interview-based cognitive assessments of orientation and attention, episodic memory, visuospatial abilities, and a combined global cognition score incorporating these assessments. Other self-reported or interview-based assessments included postlunch napping duration, nighttime sleep duration, demographic characteristics, health habits, comorbidities, functional status and social activities. According to reported napping duration, older adults were categorized as non-nappers (0 minutes), short nappers (<30 minutes), moderate nappers (30–90 minutes), and extended nappers (>90 minutes). Postlunch napping was reporting in 57.7% of participants for a mean of 63 minutes. Cognitive function was significantly associated with napping (P < .001). Between-group comparisons showed that moderate nappers had better overall cognition than non-nappers (P < .001) or extended nappers (P = .01). Non-nappers also had significantly poorer cognition than short nappers (P = .03). In multiple regression analysis, moderate napping was significantly associated with better cognition than non-(P = .004), short (P = .04), and extended napping (P = .002), after controlling for demographic characteristics, body mass index, depression, instrumental activities of daily living, social activities, and nighttime sleep duration. A cross-sectional association was found between moderate postlunch napping and better cognition in Chinese older adults. The cross-sectional design and self-reported measures of sleep limited the findings. Longitudinal studies with objective napping measures are needed to further test this hypothesis.
