社区老年人久坐行为与睡眠质量对认知功能的影响

目的 了解久坐行为与睡眠质量对社区老年人认知功能的影响。方法 采用匹兹堡睡眠质量指数量表、国际体力活动问卷短卷、简易精神状态量表及一般资料调查表，于2019年12月按照分层整群抽样法，从济南市随机抽取1 091名老年人开展问卷调查。结果 调整人口学变量后，二元logistic 回归分析结果显示，存在久坐行为的社区老年人患认知功能障碍的风险为非久坐行为者的1.880倍（OR值 = 1.880， 95 % CI = 1.267～2.790），存在睡眠障碍的老年人发生认知功能障碍的风险为无睡眠障碍者的2.160倍（OR值 = 2.160，95 % CI = 1.391～3.356）。交互作用分析结果显示，久坐行为与睡眠障碍对老年人认知功能障碍患病率具有负相乘交互作用OR值（95%CI） = 0.414（0.174～0.984）。结论 久坐行为与睡眠障碍是老年人认知功能的危险因素，且二者存在相乘交互作用。

Effects of sedentary behavior and sleep quality on cognitive function among elderly people

The aim of this study was to understand the effects of sedentary behavior and sleep quality on cognitiveimpairment among the elderly in the community. Methods The questionnaire consisted Pittsburgh Sleep Quality Index Scale(PSQI), International Physical Activity Questionnaire (IPAQ) and Mini-mental State Examination (MMSE). In December 2019,1091 elderly people were randomly selected from Jinan city to carry out the questionnaire survey. Results The results ofmultiple logistic regression analysis showed that the elder people with sedentary behaviors had a 1.880 times higher risk ofcognitive impairment than those without the sedentary behaviors (OR=1.880, 95% CI=1.267-2.790). The elder people withsleep disorders had a 2.160 times higher risk of cognitive impairment than those without (OR=2.160, 95% CI=1.391-3.356).There was a multiplied interactive effect of the sedentary behavior and sleep quality on cognitive impairment. ConclusionSedentary behavior and sleep disorders were risk factors for the elderly to be cognitive impaired, and there was a multipliedinteraction between the two.
