Abstract:Objective To understand the prevalence rate of mild cognitive impairment (MCI) among the elderly in a suburban area of Shanghai City, and to explore the risk factors of MCI in the elderly, so as to provide scientific basis for the prevention and treatment of MCI in the elderly. Methods Using cluster sampling method, 705 elderly people over 65 years old in Jiading Town Street of Jiading District in Shanghai were selected from July to December 2018 for general health status questionnaire survey and Montreal cognitive assessment-basic (MoCA-B) test. Results Seven hundred and three valid questionnaires were obtained. The MoCA-B score of the elderly in community was 24(21,26) points. The prevalence rate was 19.1%. Univariate analysis showed that compared with the MCI group, the age of the non-MCI group was lower (P < 0.05); the prevalence rate of MCI among the elderly in community with different educational levels, number of children born, living conditions, economic satisfaction degrees, activity status and whether they had diabetes mellitus, coronary heart disease and stroke had significant differences (P < 0.05), and there was no significant difference in the prevalence rate of MCI between hypertensive patients and non-hypertensive patients (P > 0.05). Multivariate unconditional Logistic regression analysis showed that advanced age (OR = 1.047, 95%CI: 1.010-1.084), three or more children born (OR = 1.876, 95%CI: 1.004-3.503), and diabetes mellitus (OR = 2.003, 95%CI: 1.338-2.997) were risk factors for MCI; living with children (OR = 0.305, 95%CI: 0.095-0.980) and above moderate exercise (OR = 0.260, 95%CI: 0.089-0.761) were protective factors for MCI. Conclusion With the increase of age, the average score of MoCA-B scale of the elderly decreases significantly. MCI intervention should be carried out as soon as possible for the elderly, who are not active and doesn′t live with their children, in order to prevent and delay the occurrence of Alzheimer′s disease.
