目的了解重庆市养老机构老年人轻度认知障碍(MCI)的患病现状及影响因素。方法2015年10至11月,整群抽取重庆市4所养老机构60岁以上老年人,采用面谈方式,应用自制的老年人一般情况调查表、简易精神状态检查、工具性日常生活活动能力量表和老年人抑郁量表进行调查。结果共调查84名老年人,其中MCI 25名(29.76%),不同性别、文化程度、经济状况,以及是否吸烟、常吃河鲜、常参加户外活动、常打麻将或棋牌、常看电视或听广播或读报纸、常参加社会活动、有宗教信仰、患有高血压的老年人,MCI患病率有显著性差异(χ2>4.271, P<0.05)。多因素Logistic回归分析显示,男性是老年人MCI患病的保护因素(OR=0.055, 95%CI: 0.005~0.618),高血压是危险因素(OR=8.281, 95%CI: 1.278~53.646)。结论重庆市养老机构老年人MCI患病率较高,应尽早针对MCI的影响因素采取有效干预措施。
ObjectiveTo investigate the prevalence status and risk factors of mild cognitive impairment (MCI) in old people in pension facilities in Chongqing, China. MethodsFrom October to November, 2015, the people above 60 years old in four pension facilities in Chongqing were cluster sampled. They were interviewed with Mini-Mental State Examination, Instrumental Activity of Daily Living Scale, self-made general situation questionnaire for the elderly and the Geriatric Depression Scale. ResultsThere were 25 MCI patients identified in 84 old people selected, with the prevalence of 29.76%. MCI prevalence was different with the factors such as genders, educational levels, economical status, smoking, eating freshwater fish frequently, participating in outdoor activities frequently, playing Mahjong/chess/cards frequently, watching TV/listening to broadcast/reading newspaper frequently, participating in social activities frequently, having religious beliefs, suffering high blood pressure (χ2>4.271, P<0.05). Based on multivariate Logistic regression analysis, male was the protective factor (OR=0.055, 95%CI: 0.005~0.618), while high blood pressure was the risk factor (OR=8.281, 95%CI: 1.278~53.646) to the MCI. ConclusionMCI is prevalent in old people in pension facilities in Chongqing, which needs intervention targeted to the risk foctors.
