芦山地震后5年雅安城市老人的认知功能及相关因素

目的:了解芦山地震5年后雅安城市老年人的认知功能现状及相关因素,为灾难性事件后老年人群心理健康及认知功能干预提供参考。方法:采取多阶段分层整群随机抽样方法,于2019年3月,选取雅安市区≥60岁老年人885名例,使用老年人一般信息调查表收集一般人口学信息、健康相关信息、受灾情况分布,采用MoCA量表(北京版)评估认知功能。结果:芦山地震后5年雅安城市老年人认知功能障碍患病率为14.9%,其中轻度为9.1%,中、重各为2.9%;不同受灾程度地区老年人的认知功能障碍患病率,差异无统计学意义。Logistics回归分析显示,年龄70~<80岁和≥80岁组的老年人更易出现认知功能障碍[OR=2.98(95%CI:1.72~5.15),OR=6.08(95%CI:3.51~10.55),均P<0.001],大专及以上受教育程度的老人不易出现认知功能障碍[OR=0.15(95%CI:0.05~0.44),P<0.001]。结论:高龄为芦山地震后5年雅安城市老人认知功能障碍的危险因素,受教育程度高为保护因素。
