Association between Grip Strength and Cognitive Function among Middle-aged and Older Adults with Stroke: Findings from the China Health and Retirement Longitudinal Study / 中国康复理论与实践

ABSTRACT

@#Objective:To explore the relationship between grips strength and cognitive function among stroke patients in China. Methods:The data of 412 post-stroke participants from the baseline survey of the China Health and Retirement Longitudinal Study (CHARLS) were selected. The association between grip strength and cognitive function was analyzed, especially in gender. Results:Grip strength was positively associated with all cognitive measures. For every 5 kg increase in grip strength, the likelihood increased 30% in correctly drawing picture (95%CI 8%-57%, <italic>P</italic> = 0.005); and the scores increased 0.15 points in episodic memory (<italic>P</italic> = 0.003), 0.30 points in Telephone Interview of Cognitive Status (TICS-10) (<italic>P</italic> = 0.001), and 0.60 points (<italic>P</italic> < 0.001) in the overall cognition scores. The association between grip strength and cognitive measures was stronger among female patients, particularly for episodic memory (<italic>P</italic> = 0.049). Conclusion:Grip strength was positively associated with cognitive function among stroke patients. The association was stronger among female patients.
