Children with allergic rhinitis demonstrated elevated risk for migraines, with the highest risk within 1 year of allergic rhinitis diagnosis, according to study results.

Researchers in China evaluated 461,850 children diagnosed with allergic rhinitis between 2000 and 2007. The investigators compared that cohort with 460,718 children without allergic rhinitis. The researchers measured the incidence of migraines in both groups.

Results revealed children with allergic rhinitis were more than three times as likely to experience migraines during the study period (HR = 3.2; 95% CI, 2.97-3.46) than children who did not have allergic rhinitis.

Among those with allergic rhinitis, boys and children aged younger than 6 years old were most likely to experience migraines.
