蒙特利尔认知评估量表在军队离退休人员轻度认知功能障碍中的应用

目的应用蒙特利尔认知评估（MOCA）量表对西安地区军队离退休人员进行轻度认知功能障碍（MCI）的筛查。方法随机、整群抽样选取西安市9个干休所304名离退休干部，同时进行个人信息、患病情况、MOCA量表、简易智能状态检查（MMSE）量表、日常活动能力（ADL）量表、抑郁自评（CES-D）量表、匹兹堡睡眠质量（PSQI）量表调查。结果西安干休所离退休干部MCI发生率为64．8％；80岁以上老年人MCI的发生率高于70岁组（P〈0．05）；教育年限小于6年者MCI的发生率高于7～12年及12年以上者（P〈0．05）；不参加体育锻炼者MCI的发生率高于经常参加体育锻炼者（P〈0．01）；有脑卒中者MCI的发生率高于无脑卒中者（P〈0．05）；MOCA量表得分与MMSE量表得分呈正相关（r=0．81），与ADL量表、CES-D量表得分呈负相关，与PSQI量表得分无显著相关。结论MOCA量表与相关评估量表具有相关性，测量方便，可行性好，能够用于军队离退休干部人群中MCI的筛查。

Montreal cognitive assessment in evaluation of mild cognitive impairment for military retired cadres

Objective To screen mild cognitive impairment （MCI） in Xi＇an military retired cadres by using Montreal cognitive assessment （MOCA） scale. Methods A random sample of military retired cadres was selected from 9 Xi＇an sanatoria by cluster sampling. Their personal information and MCI prevalence were collected and recorded. MOCA scale, Mini-mental state examination （MMSE） scale, Activities of daily living （ADL） scale, Center for epidemiologic studies depression scale （CES-D） and Pittsburgh sleep quality index （PSQI） scale were used to survey these selected cadres. Results There were 304 retired cadres sampled in this study. Among them, there were 64.8% having MCI, with the incidence significantly higher in those at age over 80 than those over 70 （P 〈 0.05）. Those educated for less than 6 years had significantly higher incidence of MCI than those for 7 to 12 years education and those for over 12 years education （P 〈 0.05）. The MCI incidence of those never taking exercise was significantly higher than that in those taking regular exercise （P 〈 0.01）. So was that for those with brain stroke than those without （P 〈 0.05）. The scores of MOCA had a positive correlation with those of MMSE （r= 0.81）, and a negative correlation with those of ADL and CES-D, but had no correlation with those of PSQI. Conclusion The score of MOCA is correlated with those of related neuropsychiatry scales. The scale is easy and feasible to operate, and can be used to screen MCI for military retired cadres.
