目的了解山西省太原市社区老年人阿尔兹海默病患病率及其影响因素。方法采用整群抽样方法抽取太原市9个社区5 964名≥65岁老年人作为调查对象,用自制问卷面对面调查老年人的人口学状况和慢性病史,对于未到现场的老年人采用电话访谈的方式进行调查;采用SPSS 13.0进行数据录入与分析。结果患阿尔兹海默病者共有290例,患病率为4.86%,Logistic回归分析结果显示,高年龄（OR=1.96,95%CI=1.70～2.28）,患有高血压（OR=1.86,95%CI=1.41～2.46）,患有高血脂（OR=2.66,95%CI=1.60～4.42）,患有糖尿病（OR=2.78,95%CI=2.02～3.82）是患阿尔兹海默病危险因素,在婚（OR=0.75,95%CI=0.75～0.99）、高学历（OR=0.75,95%CI=0.46～0.72）、脑力劳动（OR=0.50,95%CI=0.33～0.76）是患阿尔兹海默病的保护因素。结论高龄、低学历、独居、体力劳动者、高血糖、高血压、高血脂是老年人患阿尔兹海默病的危险因素。
