Objective To explore the causal relationship between left and right handgrip strength and the onset of cognitive decline, providing a reference for developing strategies to prevent cognitive decline in the elderly.
Methods Genome-wide data for left and right handgrip strength were obtained from the UK Biobank, while genome-wide data for cognitive function were sourced from a meta-analysis conducted by the Cognitive Genomics Consortium. The study employed three regression models: Inverse-Variance Weighted (IVW), MR-Egger regression, and Weighted Median, to conduct Mendelian randomization analyses on the causal relationship between left and right handgrip strength and cognitive function.
Results The IVW model results demonstrated a positive causal relationship between right handgrip strength (β=0.08, 95% CI: 0.03-0.14, P=0.004), left handgrip strength (β=0.08, 95% CI: 0.01-0.14, P=0.017), and cognitive function.
Conclusion The findings of this study support a positive causal relationship between left-hand grip strength, right-hand grip strength, and cognitive function.

目的 探索左、右手握力与认知功能之间可能的因果关联,为预防老年人认知功能下降策略的制定提供参考依据。
方法 左、右手握力的全基因组数据来源UK Biobank,认知功能的全基因组数据来源于一项基于认知基因组学联盟的meta分析。研究采用随机效应逆方差加权法(Inverse-variance weighted, IVW)、MR-Egger回归、加权中位数法三种回归模型对左、右手握力与认知功能的因果关系进行孟德尔随机化分析。
结果 IVW模型计算结果显示右手握力(β=0.08, 95% CI: 0.03 ~ 0.14, P=0.004)、左手握力(β=0.08, 95% CI: 0.01 ~ 0.14,P=0.017)与认知能力之间存在正向因果关系。
结论 本项研究结果支持左手握力和右手握力与认知功能之间存在因果关系。
