Abstract: BACKGROUND: The association between hypertension and migraine remains unclear. OBJECTIVE: The aim of this study employ multi-layered evidence chain that revealed the association between hypertension and migraine. METHODS: We first strictly included data from the NHANES 1999-2004 population and applied logistic regression, subgroup analysis and RCS to assess the correlation between hypertension, SBP, DBP and migraine. Meanwhile, LDSC and Mendelian randomization were conducted based on the GWAS to determine the causal relationship between hypertension and migraine. Inverse-variance weighted (IVW) was used as the primary method. Sensitivity analysis and Colocalization analysis were performed to confirm the robustness of the results. LDSC validated the genetic correlation between traits. Enrichment analysis revealed their underlying biological mechanisms. RESULTS: After strict inclusion in NHANES, 10,743 participants were included. The logistic regression showed a significant correlation between hypertension (OR = 1.21 [95% CI, 1.08-1.36], FDR < 0.001)、DBP (OR = 1.01 [95% CI, 1.01-1.02], FDR < 0.001) and migraine. This association did not show significant group differences in subgroup. The MR results further supported the existence of a significant causal relationship between hypertension (OR = 1.77 [95% CI, 1.43-2.30], FDR < 0.001)、DBP (OR = 1.02 [95% CI, 1.01-1.03], FDR < 0.001) and migraine onset. Additionally, the RCS analysis showed a linear relationship (P non-linear = 0.897) between the two. The LDSC result showed a significant genetic correlation between the two (Rg = 0.1092, SE = 0.028, P < 0.001). CONCLUSION: The development of migraine caused by hypertension is mainly realized through high DBP.
