摘　　要：目的全面了解海南岛55岁及以上人群轻度认知障碍(MCI)的患病率。方法采用人口学、健康史、简易精神状态检查量表(MMSE)、日常生活自理能力量表(ADL)、临床痴呆评定量表(CDR)等问卷和量表进行筛查。结果海南岛55岁及55岁以上人群MCI的患病率为4.25%,男性患病率为3.88%,女性患病率为4.57%,男女之间差异无统计学意义(P﹥0.05);各年龄组随着年龄的增加,患病率增高(P﹤0.001);相同年龄组男女之间比较,55～64岁、65～74岁年龄组女性患病率较男性高(P﹤0.05,P﹤0.01),75～84岁年龄组男性患病率较女性高(P﹤0.05),而在≥85岁的年龄组男女之间患病率差异无统计学意义(P﹥0.05)。文化程度越低,患病率越高(P﹤0.001)。结论高龄、低教育水平是海南岛MCI高发人群,应注意防治MCI,减少阿尔茨海默病(AD)的发生。Objective To investigate the prevalence of mild cognitive impairment（MCI） among 55-years old or over individuals in Hainan Island.
