Abstract:
Objective To investigate the causal relationship between walking pace(WP)with interver-tebral disc degeneration(IVDD)and low back pain(LBP)by using two-sample Mendelian randomisation(MR)analysis method.Methods A genome-wide association study database of WP,IVDD and LBP was ob-tained,and single nucleotide polymorphisms(SNP)strongly associated with exposure were obtained as the in-strumental variables.The two confounders of smoking and sedentary were conservatively removed,and the MR analyses were performed by inverse variance weighting(IVW),weighted median,and MR-Egger methods to assess the causal relationship between WP with IVDD and LBP.The consistency and accuracy of results were ensured by heterogeneity,diversity tests,MR-PRESSO and negative control.Results The I VW results showed a significant negative correlation between WP and IVDD(OR=0.348,95%CI:0.183-0.661,P=0.001)and vice versa(OR=0.972,95%CI:0.953-0.992,P=0.007).Meanwhile there was also a significant negative correlation between WP and LBP(OR=0.214,95%CI:0.119-0.385,P<0.001),but no causal re-lationship was found between LBP and WP.Conclusion Faster WP could effectively prevent the occurrence of IVDD and LBP,and IVDD may contribute to the occurrence of slow walking.
