Key clinical point: A higher dietary phytochemical index (DPI) score is associated with lower migraine frequency and improved migraine-related disability in patients with migraine.
Major finding: Patients with migraine in the third vs first tertile of the DPI showed a significant reduction in migraine frequency (incidence rate ratio 0.84; Ptrend = .009) and an improvement in migraine-related disability (β −2.48; Ptrend = .046). However, no significant association was seen between DPI and headache duration (Ptrend = .439), headache severity (Ptrend = .239), depression (Ptrend = .480), anxiety (Ptrend = .655), and stress (Ptrend = .876).
Study details: This cross-sectional study evaluated the association between DPI and the clinical and psychological characteristics of migraine headaches in 262 patients with migraine (age 20-50 years).
Disclosures: This study was supported by the Isfahan University of Medical Sciences, Isfahan, Iran. The authors declared no conflicts of interest.
