Abstract：Objective To investigate the influencing factors for mild cognitive impairment (MCI) among the elderly inpatients of the department of geriatrics, so as to provide the reference for early screening and prevention of MCI in the elderly population. Methods Inpatients aged 60 years and older and admitted to the Department of Geriatrics at the First Affiliated Hospital of Xinjiang Medical University were selected as the study subjects. Demographic information, past medical history, activities of daily living (ADL), depressive symptoms were collected through questionnaire surveys. MCI was diagnosed with Montreal Cognitive Assessment in combination with medical history and physical examination. Factors affecting MCI were identified using a multivariable logistic regression model. Results A total of 1 019 elderly patients were collected, including 472 males (46.32%) and 547 females (53.68%), and had a median age of 73.00 (interquartile range, 14.00) years. Among them, 746 patients had an educational level of junior high school or above, accounting for 73.21%, 446 patients had cerebrovascular disease, accounting for 43.77%, and 220 patients were diagnosed with MCI, with a detection rate of 21.59%. Multivariable logistic regression analysis showed that age (OR=1.354, 95%CI: 1.285-1.426), educational level (primary school, OR=0.345, 95%CI: 0.163-0.731; junior high school or above, OR=0.196, 95%CI: 0.096-0.402), ADL (moderate/severe dependence, OR=4.744, 95%CI: 2.044-11.012) and cerebrovascular disease (OR=2.335, 95%CI: 1.482-3.679) were the influencing factors for MCI among geriatric inpatients. Conclusions The MCI of the elderly inpatients of the department of geriatrics is related to age, educational level, ADL and cerebrovascular disease. Therefore, targeted health education and cognitive function training should be provided for elderly patients to prevent MCI.
