ABSTRACT
Objective: To investigate the prevalence of mild cognitive impairment MCI and influencing factors in old stroke patients in China, and provide evidence for the early risk identification and prevention of MCI. Methods: In 2024 China Ageing and Health Survey, a total of 41 859 adults aged ≥65 years were analyzed based on multistage stratified cluster probability samplings. Their mild cognitive impairment status was assessed using the Memory Impairment Scale, and their depression and anxiety status were evaluated with the Patient Health Questionnaire and Generalized Anxiety Disorder scale, respectively. Descriptive analyses with complex sampling weights and multivariable logistic regression models were used to analyze influencing factors. Results: In the adults aged ≥65 years, the prevalence of stroke was 5.54%. Among those with stroke, 45.00% had MCI. The proportion of MCI was higher in those living in western region (62.10%),women (51.02%), those aged ≥75 years (43.78%), those living in rural area (47.48%), those with education level of primary school or below (51.82%), and those with monthly household income <3 000 yuan (54.66%). Multivariable analysis indicated that MCI in stroke patients aged ≥65 years was associated with region, sex, age, residence, educational level, monthly household income, anxiety, and depression (all P<0.05). Conclusion: It is necessary to strengthen the early screening and conduct targeted interventions in populations at high-risk for stroke for the prevention of mild cognitive impairment, especially in the western region.
