Objective To investigate the prevalence of cognitive dysfunction among inpatients in Geriatrics Depart- ment of a hospital in Yunnan Province, and to analyze the influencing factors of cognitive dysfunction of the elderly.Methods A total of 2 216 admitted patients(≥60 years old) in the Department of Geriatrics of a hospital in Yunnan Province from September 2018 to August 2021 were recruited as the subjects. General data of the patients were collected. Comprehensive geriatric assessment was conducted by an internet-based platform of the Comprehensive Geriatric Assessment developed by the Department of Geriatrics of Yunnan First People's Hospital, among which cognitive function was assessed by the Mini-Mental State Examination(MMSE)phenotype. Results Among 2 216 patients, 1 087(49.1%) had normal cognitive function, 639(28.8%) had mild cognitive impairment, 285 (12.9%) had moderate cognitive impairment and 205 (9.3%) had severe cognitive impairment. According to multivariate Logistic regression analysis, increased age [OR=1.026,95% CI(1.015, 1.037),P＜ 0.001], vision decline[OR=1.290,95% CI(1.002, 1.662),P＜ 0.05], empty nest[OR=1.433,95% CI(1.009, 2.034),P＜ 0.05], family support disorder[OR=1.436,95% CI(1.120, 1.842),P＜ 0.05], insomnia [OR=1.380,95% CI(1.095, 1.740),P＜ 0.05] and suffered chronic obstructive pulmonary disease [OR=1.234,95% CI(1.008, 1.512),P＜ 0.05) were the risk factors for cognitive function in the elderly, while the individuals mainly engaged in mental activities[OR=0.678,95% CI(0.540,P＜ 0.05).0.852, P＜ 0.001], education experience of primary school[OR=0.613,95% CI(0.485,0.776,P＜0.001], secondary school[OR=0.670,95% CI(0.534, 0.839), P＜ 0.001) and university degree or above [OR=0.555,95% CI(0.410, 0.751),P＜ 0.001] were protective factors. Conclusions The prevalence of cognitive dysfunction in elderly hospitalized patients is high and closely related to a variety of factors. Specific intervention of related factors is of great significance for the early prevention of cognitive impairment in the elderly.
