Objective To evaluate the association between hypertension and cognitive impairment in the inpatients aged over 80 years. Methods Elderly patients aged over 80 years who were hospitalized in Danjiangkou City First Hospital during Jan. 2010 to Aug. 2011 were selected as objects. Mini-mental State Examination( MMSE )was used to assess the cognitive function, and multifactor regression was used to assess association between hypertension and cognitive impairment in these inpatients. Results 93 patients were enrolled,including 35 with cognitive dysfunction. Single factor analysis showed that age,gender,education time,hypertension,and diabetes were correlated with elderly cognitive dysfunction. Multifactor regression demonstrated that age,gender,and hypertension were independent risk factors for elderly cognitive dysfunction. Conclusion Hypertension is an independent risk factor for cognitive dysfunction in the patients aged over 80 years.%目的研究高血压与老年人认知功能障碍之间的关系.方法 选取2010年1月至2011年8月在丹江口市第一医院住院的80岁以上的老年人为研究对象,用简易精神量表评价认知功能,采用多因素回归分析高血压与老年人认知功能障碍的关系.结果 93例患者中认知功能障碍者35例.单因素分析显示,年龄、性别、教育年限、高血压及糖尿病与老年人认知功能障碍有关;多因素分析显示,年龄、性别、高血压是老年人认知功能障碍的独立危险因素.结论 高血压是80岁以上老年人认知功能障碍的独立危险因素.
