平顶山市社区老年人轻度认知功能障碍现况

Situation of mild cognitive impairment among the elderly in Pingdingshan community

目的：探讨平顶山市社区老年人轻度认知功能障碍（MCI）现况及相关影响因素。方法：采用整群随机抽样法进行抽样后,对平顶山市837名社区老年人进行一般情况问卷调查及MCI筛查。结果：平顶山市社区老年人MCI患病率为11.6%。不同年龄、文化程度、居住情况、睡眠时间、社交情况的老年人MCI患病率差异均具有统计学意义（P〈0.05）,随着年龄的增长,MCI患病率有升高的趋势（Z=3.824,P〈0.001）。Logistic回归结果显示居住情况（OR=3.203,95%CI为2.594~3.812）、社交情况（OR=0.576,95%CI为0.179~0.973）、文化程度（OR=0.507,95%CI为0.194~0.820）是MCI的影响因素。其中独居是MCI的危险因素,常参加社交是MCI的保护因素。结论：应对可控因素进行积极干预,提高老年人群的认知能力,降低MCI的发病率。

Aim： To investigate the situation of mild cognitive impairment（ MCI） and its influencing factors among the elderly in Pingdingshan community. Methods： A total of 837 elderly people in the community were sampled by cluster random sampling method and investigated with a questionnaire and screening for mild cognitive impairment. Results： The prevalence rate of MCI was 11. 6%. Age,education level,living conditions,sleep time,and social conditions significantly affected prevalent rate（ P 0.05）. The prevalence of MCI increased with age（ Z = 3. 824,P 0. 001）. Conditional logistic regression analysis showed that the influencing factors included living conditions（ OR = 3. 203,95% CI： 2. 594- 3. 812）,social conditions（ OR = 0. 576,95% CI： 0. 179- 0. 973）,education level（ OR = 0. 507,95% CI： 0. 194- 0. 820）. Living alone is a risk factor of MCI,and often participating in social activities is a protective factor of MCI. Conclusion： The measures against controllable factors should be actively taken to improve the cognitive function of the elderly population,and reduce the incidence of MCI.
