Key result
Stronger grip strength, faster walking speed, and faster repeated chair stands were significantly associated with better cognitive function subdomains in patients with hypertension.
Cross-Sectional
Yes
In middle-aged and older individuals with hypertension, physical performance measures such as grip strength and walking speed are positively associated with cognitive function.
May inform cognitive risk stratification via physical performance in hypertension; hypothesis-generating and requires longitudinal confirmation before practice change.
The purpose of the study was to examine the independent associations of each individual physical performance measure (i.e., grip strength, walking speed, repeated chair stands, and balance test) with subdomains of cognitive function and to determine predictors for each subdomain of cognitive function. A secondary data analysis was performed using a nationally representative middle-aged and older sample of hypertensive population. The findings showed that after adding all four physical performance measures, stronger grip strength was significantly associated with better visuospatial abilities, episodic memory, orientation/attention, and overall cognitive function. In addition, faster walking speed and faster repeated chair stands were strongly associated with better episodic memory and overall cognitive function, respectively. Because grip strength was significantly associated with several subdomains of cognitive functioning, it seems conceivable that increasing physical activity would improve both grip strength and cognitive function in patients with hypertension.

Zuo et al. (2018) conducted a cross-sectional in Hypertension. Physical performance measures (grip strength, walking speed, repeated chair stands, and balance test) was evaluated on Subdomains of cognitive function (visuospatial abilities, episodic memory, orientation/attention, and overall cognitive function). Stronger grip strength, faster walking speed, and faster repeated chair stands were significantly associated with better cognitive function subdomains in patients with hypertension.
