Abstract Objective To examine the independent effect of depression on activities of daily living of patients with mild cognitive impairment （MCI）. Methods Data were obtained through the face-to-face interview. Totally 154 elderly patients that were screened from 552 old people by the Montreal Cognitive Assessment（MoCA）were diagnosed as MCI. They were investigated with the Geriatric Depression Scale,and instrumental ability of daily living（IADL）were measured by the Functional Activities Questionnaire. The effect of depression on IADL of patients with MCI was analyzed by logistic regression analysis. Results The prevalence of depressive symptoms among Chinese elders with MCI was 31.82%. The scores of Medical Outcomes Study Social Support Survey, and Functional Activity Questionnaire of depression group and non-depression group were significantly different （P<0.05）. Logistic regression analysis showed that scores of Functional Activity Questionnaire was positively associated with the scores of Memory Inventory for the Chinese（OR=1.36,95%CI：1.15-1.61）and depression（OR=6.19,95%CI：2.07-18.55）. Conclusion The prevalence of depression in elderly patients with MCI was high. Depression would significantly reduce the IADL of the old patients with MCI. Medical workers should be aware of the extent and impact of depressive symptoms in MCI and take active measures in evaluating and treating the depressive symptoms.
