Key clinical point: This Mendelian randomization study showed that leisure screen time (LST) worsens migraine, whereas moderate to vigorous physical activity (MVPA) alleviates it, with hypertension and diastolic blood pressure (DBP) being responsible for the effects of MVPA or LST on migraine.
Major findings: Genetically predicted LST was associated with a significantly increased risk for migraine (odds ratio [OR] 1.28; P < .001), whereas MVPA was linked to a significantly reduced risk (OR 0.73; P = .000006). Hypertension mediated 4.86% and 24.81% of the effects of MVPA and LST on migraine risk, respectively, and DBP accounted for 4.66% of the effects of MVPA on migraine risk.
Study details: This study included 18,477 patients with migraine and 287,837 control individuals without migraine from the FinnGen consortium and 26,052 patients with migraine and 487,214 control individuals without migraine from the large-scale genome-wide association studies.
Disclosures: This study was supported by grants from the National Natural Science Foundation of China and others. The authors declared no conflicts of interest.
