267例80岁以上老人中文版简易智能状态检查结果分析

MMSE results of 267 elderly persons aged above 80 in Bama

目的调查广西巴马地区80岁以上老人的认知功能,探讨应用中文版简易智能状态检查(MMSE)对农村长寿老人进行认知功能筛查的可行性。方法截断面调查,整群抽取巴马县甲篆乡80岁以上老人。应用“巴马地区长寿老人心理健康调查表”,包括人口学资料、国际通用的标准化工具MMSE等。结果共调查267名80岁以上老人,其中男性37.1%,女性62.9%,平均年龄88.19岁。MMSE总分随年龄增长逐渐下降,文盲组20.83±4.53,小学组20.23±3.53,中学组20.70±3.30,与常模相比,文盲组和中学组均有显著性差异(P<0.01)。男性MMSE总分均分22.59±5.13,女性MMSE总分均数19.56±3.17,二者比较差异有显著性(P<0.01)。MMSE敏感性较高(100%)而特异性稍差(70.78%)。回归分析提示高龄、受教育程度低、数字广度测验得分低、视力障碍、缺乏社会支持、参加社会活动和体力劳动少、有固定医院就诊等是影响老年人认知功能的危险因素。结论巴马长寿老人总体认知功能良好,MMSE适用于农村长寿老人认知功能筛查。

ObjectiveTo investigate the cognitive function of the long lived elders in Bama and to probe into the feasibity of using MMSE to identify the cognitive function of the rural long lived elders in the longevity area.MethodThe study was a cross sectional survey, sampling the whole group aged 80 years and above, who live in Jiajian country, Bama County. The instruments used were “the Mental Health Survey Questionnaire for the Old Elderly in Bama”, which includes social demographic data and a battery of international standardized instruments ResultsWith 267 elderly persons over 80 years interviewed, 37.1 percent of them were male and 62.9 percent of them were female. Their average age reached 88.19. The total MMSE marks gradually decrease along with the increasing of the age. The total MMSE score is 20.83±4.53 in the illiterate group,and 20.23±3.53 in the group with a primary level education,and 20.23±3.53 in the group with a middle school level education: 20.70 ±3.30. Compared with the common model, both the illiterate group and the group with a middle school level education show a remarkable difference(P<0.01). The total MMSE marks are 22.59±5.13 for male while 19.56 ±3.17 for female. There is a big gap between the two groups. The MMSE sensitivities are comparatively high while the MMSE exceptionalities are comparatively low. Cognitive dysfunction was associated with elder old, education level, the DS scores, and lower level social support. ConclusionMost of the long lived elders in Bama remain good cognitive function. MMSE is applicable to identify the cognitive function of the rural long lived elders.
