山东省农村老年人衰弱和认知功能障碍相关性的分析

Analysis of Correlation between Frailty and Cognitive Dysfunction in Rural Elderly in Shandong Province

摘要: 目的：探讨农村老年人衰弱和认知功能障碍的关系。方法：采用整群随机抽样的方法，分别在德州，济宁，泰安，临沂的农村地区选取了309名老年人展开调查。采用一般情况调查表、Fried衰弱表型量表(Frailty Phenotype, FP)以及简易精神状态检查量表(Mini-Mental State Examination, MMSE)进行资料收集。结果：本研究的人群衰弱的发生率为8.7%，衰弱前期的发生率为44.7%，认知功能障碍的发生率为17.5%。Spearman相关分析显示，农村老年人FP和MMSE总分存在显著负相关(rs = −0.348, P < 0.01)；二元logistic回归分析结果显示，步速减慢(β = −0.995, P < 0.05)和身体活动减少(β = −1.257, P < 0.05)是认知功能障碍的影响因素。结论：农村老年人衰弱和认知功能障碍存在相关性，对于躯体活动量减少和步行速度减慢的老年人应重点关注其认知功能，进行早期干预。

Abstract: Ob-jective: To explore the relationship between frailty and cognitive dysfunction in rural elderly. Methods: Cluster random sampling was used to select 309 elderly people from rural areas in Dezhou, Jining, Tai’an and Linyi. Data were collected by general information questionnaire, Frailty Phenotype (FP) scale and Mini-Mental State Examination (MMSE) with good reliability. Results: The incidence of frailty was 8.7%, the incidence of prefrailty was 44.7%, and the incidence of cognitive dysfunction was 17.5%. Spearman correlation analysis showed that there was a significant negative correlation between FP and MMSE scores (rs = −0.348, P < 0.01). Binary logistic regression analysis showed that slow walking speed (β = −0.995, P < 0.05) and reduced physical activity (β = −1.257, P < 0.05) were the influencing factors of cognitive dysfunction. Conclusion: There is a correlation be-tween frailty and cognitive dysfunction among rural elderly. For the elderly with reduced physical activity and slow walking speed, attention should be paid to the evaluation of their cognitive func-tion and early intervention.
