摘要
目的 了解中国老年人认知功能现状及体力活动强度对其认知功能的影响,为改善中国老年人认知功能现状及制订预防措施提供参考。方法 使用2020年中国健康与养老追踪调查数据库,收集老年人认知功能评分及体力活动等一般资料,对老年人认知功能障碍进行单因素及多因素分析,同时依据文化程度对老年人的认知功能评分进行分层线性回归分析。结果 共纳入8 162名老年人,认知功能评分为(17.56±6.99)分,其中认知功能障碍检出率为38.89%。logistic回归分析结果显示,高龄、女性、农村、夜间睡眠时间≥8 h、无社交、体力活动为高强度是影响认知功能的危险因素(均P<0.05)。依据不同文化程度进行分层回归分析结果显示,中强度体力活动较高强度体力活动更利于患者的认知功能(均P<0.05)。结论 老年人认知功能障碍发生率较高,影响因素复杂,每周有中强度体力活动是老年人的认知功能障碍的保护因素。
Objective To explore the level of cognitive function in Chinese older adults,to explore the impact of physical activity in-tensity on cognitive function,and to provide references for improving cognitive function among the elderly in China and formulating preventive measures.Methods The 2020 China Health and Retirement Longitudinal Study database was searched to collect cogni-tive function and physical activity among older adults.Univariate and multivariate analyses were performed to identify factors af-fecting cognitive dysfunction in older adults.Cognitive function of older adults was stratified according to their educational level for hierarchical linear regression.Results A total of 8162 older adults were included and their cognitive function score was(17.56±6.99),with the detection rate of cognitive dysfunction being 38.89%.The results of logistic regression showed that advanced age,female,living in rural area,night time sleep duration≥8 h,without social activities,and high-intensity physical activity were risk factors of cognitive dysfunction(all P<0.05).The results of hierarchical linear regression showed that moderate-intensity physi-cal activity was more conducive to cognitive function than high-intensity physical activity(all P<0.05).Conclusion The incidence of cognitive dysfunction in older adults is relatively high,and the influencing factors are complex.Moderate-intensity physical ac-tivity per week is a protective factor for cognitive dysfunction among older adults.
