Abstract: ObjectiveTo investigate the prevalence status and risk factors of mild cognitive impairment (MCI) in old people in pension facilities in Chongqing, China. MethodsFrom October to November, 2015, the people above 60 years old in four pension facilities in Chongqing were cluster sampled. They were interviewed with Mini-Mental State Examination, Instrumental Activity of Daily Living Scale, self-made general situation questionnaire for the elderly and the Geriatric Depression Scale. ResultsThere were 25 MCI patients identified in 84 old people selected, with the prevalence of 29.76%.

Based on multivariate Logistic regression analysis, male was the protective factor (OR=0.055, 95%CI: 0.005~0.618), while high blood pressure was the risk factor (OR=8.281, 95%CI: 1.278~53.646) to the MCI.
