Abstract：
UNASSIGNED: Although there have been studies on the association of handgrip strength or walking speed alone with cognitive abilities, few studies have determined the combined associations of handgrip strength and walking speed with cognitive function. Therefore we aimed to explore the independent and combined associations of handgrip strength and walking speed with cognitive function in Chinese older adults using a nationally representative sample.
UNASSIGNED: This cross-sectional study included 4,577 adults aged 60 and older. Handgrip strength was measured using a dynamometer and walking speed was assessed using a 2.5-meter walking test. Both handgrip strength and walking speed were organized into low, normal, and high tertiles according to the sample distribution. Cognitive function was measured using the Telephone Interview for Cognitive Status.
UNASSIGNED: Handgrip strength and walking speed were significantly associated with cognitive function. Participants with low handgrip strength or low walking speed separately had a higher rate of lower cognitive function (adjusted odds ratio (OR): 1.22 (95% CI: 1.04 - 1.44) for low handgrip strength; 1.54 (95% CI: 1.31 - 1.81) for low walking speed). Those with both low handgrip strength and low walking speed had an additively higher rate of lower cognitive function (adjusted OR: 1.72 (95% CI: 1.32 - 2.24)).
UNASSIGNED: Having low handgrip strength or low walking speed is associated with a greater likelihood of lower cognitive function and vice versa. The concurrence of having low handgrip strength and low walking speed has an additive effect on cognitive function in older adults.

摘要：
■尽管已经有关于握力或步行速度与认知能力的关联的研究，很少有研究确定握力和步行速度与认知功能的综合关联。因此，我们旨在使用具有全国代表性的样本，探讨中国老年人的握力和步行速度与认知功能的独立和组合关联。
■这项横断面研究包括4,577名60岁及以上的成年人。使用测力计测量握力，并使用2.5米步行测试评估步行速度。握力和步行速度都被组织为低，正常,根据样本分布和高三分位数。使用认知状态电话访谈来测量认知功能。
■握力和步行速度与认知功能显着相关。低握力或低步行速度的参与者分别具有较高的认知功能降低率（低握力的调整比值比（OR）：1.22（95％CI：1.04-1.44）；低步行速度的1.54（95％CI：1.31-1.81））。那些手握力量和步行速度都较低的人认知功能低下的比率更高（调整后的OR：1.72（95％CI：1.32-2.24））。
■握力力低或步行速度低与认知功能降低的可能性更大，反之亦然。同时具有低的握力和低的步行速度对老年人的认知功能具有累加作用。
