Abstract： System-justifying belief pertains to perceiving the fairness and legitimacy of the existing social system. It fulfills a palliative function in safeguarding mental health through three psychological mechanisms: alleviating ideological dissonance, compensating for personal control, and denying or minimizing threats. The efficiency of these mechanisms is also shaped by contextual, individual, and temporal factors. Nevertheless, the psychological defense viewpoint overlooks the potential role of system-justifying beliefs in fostering a “coping” approach to preserve mental health. Future research should further validate and refine the defense-coping model, focus more on the adverse effects of the palliative function, enhance the measurement tools, and expand the breadth of inquiry.

Abstract： Background China has entered a comprehensive aging society，and stroke is the primary cause of death and disability among adults in China，post-stroke cognitive impairment has become an important cause for long-term disability and quality of life decline in stroke patients. Objective To analyse and clarify the prevalence and influencing factors of cognitive impairment in elderly stroke patients by Meta-analysis. Methods CNKI，Wanfang Data Knowledge Service Platform，VIP，China Biology Medicine disc（CBM），PubMed，Embase，Cochrane Library，and Web of Science were searched by computer to collect cohort，case-control，and cross-sectional studies on influencing factors of cognitive impairment in elderly stroke patients from inception to 2023-02-12. After independent screening of the literature and data extraction by two investigators，the quality of the literature was assessed and a Meta-analysis of the prevalence and influencing factors of cognitive impairment in elderly stroke patients in China was performed using Stata 14.0 software. Results A total of 46 papers were included，with 3，281 cases of cognitive impairment and 27 influencing factors involved. The Meta-analysis results showed that the prevalence of cognitive impairment in elderly stroke patients in China was 42.4%〔95%CI（36.6%，48.3%〕；female〔OR=4.167，95%CI（1.937，8.967），P<0.001〕，hypertension〔OR=2.824，95%CI（2.292，3.481），P<0.001〕，systolic blood pressure〔OR=1.572，95%CI（1.444，1.711），P<0.001〕，diabetes mellitus〔OR=3.344，95%CI（2.611，4.284），P<0.001〕，hyperlipidemia 〔OR=2.228，95%CI（1.091，4.547），P=0.028〕，carotid plaque 〔OR=2.544，95%CI（1.076，6.014），P=0.033〕，infarction location of frontal lobe〔OR=1.615，95%CI（1.167，2.235），P=0.004〕，infarction location of temporal lobe〔OR=1.739，95%CI（1.246，2.427），P=0.001〕，multiple cerebral infarction〔OR=2.583，95%CI（2.009，3.321），P<0.001〕，encephalanalosis 〔OR=2.943，95%CI（1.938，4.469），P<0.001〕，homocysteine （Hcy）〔OR=2.209，95%CI（1.656，2.948），P<0.001〕，hyperhomocysteinemia〔OR=3.043，95%CI（2.092，4.426），P<0.001〕，high-sensitivity C-reactive protein （hs-CRP）〔OR=4.331，95%CI（1.756，10.685），P=0.001〕，and National Institutes of Health Stroke Scale （NIHSS）score >10〔OR=1.977，95%CI（1.320，2.961），P=0.001〕 were risk factors for cognitive impairment in elderly stroke patients in China. Conclusion The prevalence of cognitive impairment in elderly stroke patients in China was high （42.4%），and female，hypertension，systolic blood pressure，diabetes mellitus，hyperlipidemia，carotid plaque，infarction location of frontal lobe and temporal lobe，multiple cerebral infarction，encephalanalosis，Hcy，hyperhomocysteinemia，hs-CRP，and NIHSS score >10 were risk factors for cognitive impairment in elderly stroke patients in China.
