Objective To investigate the mediating role of physical activity and negative psychological state be-tween sleep quality and cognitive function in stroke patients.Methods A total of 119 patients who were admitted and di-agnosed with acute ischemic stroke(AIS)in Zibo Central Hospital from January 2021 to December 2022 were selected,and a self-made scale was used to conduct a questionnaire survey.A Pearson correlation analysis was used to investigate the correlation of physical activity and negative emotions with sleep quality and cognitive function,and the hierarchical re-gression method was used to investigate the mediating role of physical activity and negative emotions.Results The 117 patients had a Pittsburgh Sleep Quality Index of(8.39±1.20).There were significant differences between the two groups in sex,age,physical activity score,Hospital Anxiety and Depression Scale score,and Montreal Cognitive Assessment Scale score(P<0.05).The Pearson correlation analysis showed that sleep quality score was negatively correlated with physical activity score and cognitive function score(r=-0.677 and-0.750,P<0.001)and was positively correlated with negative emotion score(r=0.585,P<0.001).The hierarchical regression analysis showed that physical activity and nega-tive emotions had a mediating role between sleep quality and cognitive function(P<0.05).Conclusion AIS patients have poor sleep quality after 30 days.There is a good correlation between sleep quality and physical activity/negative emo-tions/cognitive function,and physical activity and negative emotions plays a mediating role between sleep quality and cogni-tive function.
