Abstract:
Objective:To investigate the prevalence and influencing factors of mild cognitive impairment (MCI) among middle-aged and elderly people in Xihu District, Hangzhou City, so as to provide insights into prevention and intervention of MCI among middle-aged and elderly people.
Methods:People aged 55 years and above were sampled from Xihu District using the multi-stage random sampling method, and demographic information, lifestyle behaviors, and chronic disease were collected through questionnaire surveys. The prevalence of MCI was assessed using the Montreal Cognitive Assessment, and influencing factors for MCI were analyzed using a multivariable logistic regression model.
Results:A total of 440 valid questionnaires were recovered, with an effective recovery rate of 97.78%. There were 190 males (43.18%) and 250 females (56.82%). There were 179 respondents at ages of 55 to <65 years, accounting for 40.68%. The prevalence of MCI was 18.64%. Multivariable logistic regression analysis showed that the risk of MCI was higher among the middle-aged and elderly people who were aged 65 to 95 years (55 to <65 years as the reference, 65 to <75 years, OR=4.156, 95%CI: 1.284-13.201; 75 to 95 years, OR=5.013, 95%CI: 1.752-14.126), were smokers (OR=4.768, 95%CI: 1.560-14.580), had higher daily cooking oil intake (OR=2.128, 95%CI: 1.062-4.199), had diabetes (OR=4.137, 95%CI: 1.144-4.958) and had hypertension (OR=8.093, 95%CI: 1.697-38.593); while the risk of MCI was lower among the middle-aged and elderly people who were engaged in mental labor (OR=0.074, 95%CI: 0.007-0.756) and had a monthly household income per capita of 4 000 yuan and above (4 000 to <8 000 yuan, OR=0.071, 95%CI: 0.014-0.358; 8 000 yuan and above, OR=0.009, 95%CI: 0.001-0.136).
Conclusion:MCI among middle-aged and elderly people in Xihu District is affected by age, occupation, monthly household income per capita, smoking, daily cooking oil intake, diabetes and hypertension.
