Objective To understand the prevalence rate of mild cognitive impairment (MCI) and its related factors in community elderly so as to provide evidence for the community intervention. Methods A cross-sectional study was performed in a random sampling of 925 elderly people. Mini-mental state examination (MMSE), activities of daily living (ADL) scale and questionnaire were used for face-to-face interview. Chi-square test and logistic regression analysis were applied in this study. Results The prevalence rate of MCI was 21.1% in elderly people. Female, high age, illiteracy, loss of spouse, lack of exercise, no professional activitives and not doing some work for the descendants were the risk factors for MCI. Conclusions The aging and the low educational level are the risk factors for MCI in the elderly. High self-care ability scores are the protective factors for MCI.
