目的了解山西省太原市矿区老年人轻度认知功能障碍（MCI）患者的人群分布特征及认知功能变化情况。方法于2006年9-12月,用典型抽样法选取太原市矿区（西山、官地、河涝湾）60岁~老年人作为调查对象。调查内容包括一般情况、认知功能和生理指标。共调查1 713人,从中筛出MCI患者进行认知功能测查,采用SPSS11.0软件进行分析。结果太原市社区MCI患病率为5.43%;不同年龄组（χ^221.099,P=0.000）、不同文化程度（χ^28.078,P=0.044）及婚姻状况患病率（χ^2153.494,P=0.000）差异有统计学意义;男性各认知测验中知识得分最高,空间推理得分最低;女性知识得分最低,短期视觉记忆得分最高;知识、图片排列得分男性高于女性;数字广度、短期视觉记忆得分女性高于男性;不同年龄女性算术（F=3.155,P=0.023）、情景记忆（F=3.186,P=0.010）、短期视觉记忆（F=3.172,P=0.022）差异有统计学意义;进一步分析女性情景记忆、短期视觉记忆组间差异有统计学意义。结论不同年龄组及性别患者的认知损伤表现不同。

Objective To observe the cognitive status and the prevalence of mild cognitive impairment（MCI） among aged people in mine area of Taiyuan city.Methods A cross-sectional study among people ≥60 years old was conducted with typical sampling in Sept.through Dec,2006 in the communities of Taiyuan.Cognitive function,social demographic character and physical status of 1 713 people were investigated.And MCI patients were screened in the survey.SPSS11.0 software was abopted for statistical analysis.Results The morbidity of MCI in the subjects was 5.43% with significant difference between different age groups（χ^221.099,P=0.000）,different education（χ^28.078,P=0.044）,and different marriage status（χ^2153.494,P=0.000）.The score of knowledge was the highest and the space reasoning was the lowest in the male.While in the female the knowledge was the lowest and the short time visual memory was the highest.The scores of knowledge,picture arrangement were higher in the male while the number scope,short time visual memory（F=3.186,P=0.010） and scene memory were higher in the female.The score of calculation（F=3.155,P=0.023）and scene memory（F=3.172,P=0.022）were statistical different between different female guoups.Conclusion The different MCI patients have different cognitive impaiment.
