Abstract：Objective To investigate the prevalence of mild cognitive impairment (MCI) in the elderly in Songzi City, to explore the risk factors of elderly MCI so as to provide evidence for effectively preventing elderly MCI. Methods A cluster sampling method was used to select 1,248 elderly persons aged 60 years and above in Songzi City from January 2015 to February 2016, and a questionnaire survey on general health condition was conducted. The Montreal Cognitive Assessment (MoCA) Scale, the Mini Mental State Examination (MMSE) Scale and Activity of Daily Living (ADL) Scale were used in combination with the relevant standards to screen MCI in all the subjects. And the factors influencing MCI incidence were analyzed and concluded from 3 aspects general information, common cardiovascular and cerebrovascular diseases and lifestyle. Results A total of 1,248 valid questionnaires were retrieved. 180 patients with MCI were screened out, and the incidence rate of MCI was 14.42%. The incidence rates of MCI of elderly groups with different ages, living areas (city/town), educational backgrounds and living conditions (solitary/non-solitary) showed statistically significant differences (P<0.05). The older the age and the lower the educational background, the higher the incidence rate of MCI. The incidence rate of MCI was significantly higher in the rural elderly than in the urban ones. The incidence rate of MCI of the elderly living alone was significantly higher than that of the elderly living with family members. Single factor analysis showed that hypertension, heart disease, diabetes, hyperlipidemia and smoking had no effect on the incidence of MCI (P>0.05), while stroke, alcohol drinking, tea drinking and exercise had a certain impact on the incidence of MCI (P<0.05). The incidence rates of MCI in the elderly with cerebral apoplexy (19.46%) and alcohol drinking (19.86%) were both higher than those of the elderly without cerebral apoplexy (13.55%) and alcohol drinking (11.64%). The incidence rates of MCI in the elderly with frequent tea drinking (10.34%) and exercise (8.67%) were significantly lower than those of the elderly\ with unfrequent tea drinking (16.84%) and exercise (19.55%), with statistically significant differences (P<0.05). Multifactor non-conditional logistic regression analysis showed that age, area, educational background, living condition, stroke, frequent alcohol drinking, regular tea drinking and regular exercise were the influencing factors of MCI. Conclusions It is necessary to conduct MCI prevention and interventions in the elderly with older age and lower educational level, living alone and living in villages as soon as possible. And more attention should be paid to the elderly with stroke and frequent alcohol drinking so as to delay and prevent the occurrence of senile dementia.
