Current evidence of whether napping promotes or declines cognitive functions among older adults is contradictory. The aim of this study was to determine the association between nap duration and cognitive functions among Saudi older adults.
Old adults (> 60 years) were identified from the Covid-19 vaccine center at Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia between May and August 2021. Face-to-face interviews were conducted by a geriatrician or family physicians. Data collected for each participant included sociodemographic, sleep patterns, health status and cognitive functions. St. Louis University mental status (SLUMS) was used to assess the cognitive functions. A multi-Linear regression model was used to determine the association between cognitive functions and nap duration.
Two-hundred participants (58 females) aged 66 ± 5 years were recruited. Participants were categorized according to their nap duration into non-nappers (0 min), short nappers (> 0- ≤ 30 min), moderate nappers (> 30-≤ 90 min), and extended nappers (> 90 min). The mean duration of the nap was 49.1 ± 58.4 min. The mean SLUMS score was 24.1 ± 4.7 units. Using the multi-linear regression model, the mean total SLUMS score for extended nappers was, on average, significantly lower than non-nappers [-2.16 units; 95% CI (-3.66, -0.66), = < 0.01] after controlling for the covariates (age, sex, education level, sleep hours, diabetes mellitus, hypertension, pain).
Extended napping was associated with deterioration in cognitive function among Saudi older adults.
目前关于午睡对老年人认知功能是有促进作用还是有衰退作用的证据相互矛盾。本研究的目的是确定沙特老年人午睡时长与认知功能之间的关联。
2021年5月至8月期间，从沙特达曼伊玛目阿卜杜勒拉赫曼·本·费萨尔大学的新冠疫苗接种中心招募了老年人（年龄>60岁）。由老年病医生或家庭医生进行面对面访谈。为每位参与者收集的数据包括社会人口统计学信息、睡眠模式、健康状况和认知功能。使用圣路易斯大学精神状态量表（SLUMS）评估认知功能。采用多元线性回归模型来确定认知功能与午睡时长之间的关联。
招募了200名年龄为66±5岁的参与者（58名女性）。参与者根据午睡时长分为不午睡者（0分钟）、短时间午睡者（>0至≤30分钟）、中等时长午睡者（>30至≤90分钟）和长时间午睡者（>90分钟）。午睡的平均时长为49.1±58.4分钟。SLUMS平均得分为24.1±4.7分。在控制协变量（年龄、性别、教育水平、睡眠时间、糖尿病、高血压、疼痛）后，使用多元线性回归模型，长时间午睡者的平均总SLUMS得分平均显著低于不午睡者[-2.16分；95%置信区间（-3.66，-0.66），P<0.01]。
在沙特老年人中，长时间午睡与认知功能衰退有关。
