This study aimed to investigate the causal relationship of EA with CP using Mendelian randomization (MR).Methods: Single nucleotide polymorphisms (SNPs) for EA were selected from the Social Science Genetic Association Consortium (SSGAC). Inverse-variance weighted (IVW), weighted median, penalized weighted median, maximum likelihood (ML), and MR-Egger methods were used to estimate causal effects. Two sample MR analyses were undertaken to assess whether EA has a causal effect on CP. We also performed mediation analyses to estimate the mediation effects.Results: A genetically predicted higher EA was associated with a decreased risk of multisite chronic pain (MCP) (odds ratio [OR] = 0.772, 95% confidence interval [CI] 0.732– 0.816 per one standard deviation of longer education, P < 0.05), and the Genome-wide association studies (GWAS) data for chronic widespread pain (CWP) supported the result mentioned above. Potential mediators included body mass index (BMI) (OR = 1.176, 95% CI 1.091– 1.267, P < 0.05), smoking (OR = 1.054, 95% CI 1.028– 1.081, P < 0.05), and depression (OR = 1.201, 95% CI 1.147– 1.258, P < 0.05) have all been proven to be causally associated with MCP. The proportions of the effects of genetically predicted EA mediated through genetically predicted BMI, smoking, and depression were 17.1%, 23.6%, and 9.2%, respectively.Conclusion: Genetically predicted higher educational attainment reduces multisite chronic pain risk, partially mediated by body mass index (17.1%), smoking (23.6%), and depression (9.2%), highlighting education’s protective role and its potential in chronic pain prevention strategies. Keywords: educational attainment, chronic pain, Mendelian randomization, risk factors
