Association between wine consumption and migraine: a systematic review and meta-analysis of cross-sectional.

BACKGROUND

It seems that diet is one of the main triggers of migraine; one of the most studied is alcohol, and also, over the years, red wine has been shown to trigger headaches. Therefore, this systematic review and meta-analysis aims to examine the strength of the association between wine consumption and migraine.

METHODS

In this systematic review and meta-analysis, a search of MEDLINE (via PubMed), Scopus, Cochrane, and Web of Science databases was conducted to assess the association between wine consumption and migraine, covering baseline to December 2023. Pooled Odds Ratio (p-OR) were calculated using the DerSimonian and Laird methods. This study was previously registered in PROSPERO (CRD42024511115). The risk of bias was evaluated using The Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies.

RESULTS

Five studies were included in this systematic review, and only four of them were in the meta-analysis. Using the DerSimonian and Laird method, the p-OR for the effect of wine consumption on migraine was 0.63 (95% CI 0.36-1.09). The included studies after the risk of bias assessment showed a moderate risk of bias.

CONCLUSIONS

The findings of this systematic review and meta-analysis indicate that there is no conclusive evidence to support an increased or decreased risk of migraine associated with wine consumption.
