Body mass index and its association with various features of migraine: A cross-sectional study from Saudi Arabia

Introduction: Migraine is a highly prevalent condition, and prevalence of obesity is also increasing. Results of studies addressing association of body mass index (BMI) with migraine and its features are conflicting. In this cross-sectional study, we aim to assess association between BMI and various migraine features. Methods: This study was conducted in the Headache Clinic of King Fahd Hospital of University, Al Khobar, Saudi Arabia. Interviews were conducted by three consultant neurologists. Migraine was defined according to the International Headache Society and BMI was calculated as weight (kilograms)/height (m2). Results: Of total of 121 patients, 79% were female. Almost 87.6% of patients were taking prophylactic medications. Majority of patients had attack for more than 24 h (60.3%), pulsating character (81%), moderate-to-severe intensity (92.6%), associated with nausea and/or vomiting (75.2%), and photophobia/phonophobia (91.7%). About 29.8% of patients were normal weight, 28.1% were overweight, and 39.7% were obese and morbidly obese. There was insignificant association between various categories of BMI and features of migraine, that is, unilateral location (P = 0.385), pulsating character (P = 0.571), moderate-to-severe intensity (P = 0.187), nausea and/or vomiting (P = 0.582), and photophobia and/or phonophobia (P = 0.444). Conclusion: In our study, we did not find an association between BMI and various features of migraine.
