Abstract
Background: Several studies have demonstrated an association between obesity and
migraine. It’s still unclear whether migraine is the cause or it's the result of obesity.
Objective: We investigated the prevalence of migraine among obese and non-obese
individuals and analyzed the relationship between migraine prevalence and obesity.
Patients and Methods: This is cross-sectional observational study was carried out at the
neurology outpatients’ department of the Rizgary Teaching Hospital in Erbil, Iraq, from July
1st , 2018 to September 30, 2019. We interviewed and examined 300 persons, both obese
(n=154) and non-obese (n=146), and of both gender. All of them were adults (>18 years old).
Each person's weight, height, body mass index (BMI), and waist circumference were
measured.The diagnosis of migraine was made according to the International Headache
Society’s criteria. Obesity was present if the individual’s BMI is ≥30 and/or waist-to-hip
ratio is >0.9 in females and >1.0 in males.
Results: Out of the 300 persons, 14 males (8.5%) got migraines while migraine was found in
37 females (27.4%), irrespective of their weight. Out of the 300 persons, the prevalence of
migraine among obese individuals was 21.4% (n=33) and while in non-obese individuals was
12.3% (n=18). There was a statistically significant difference between the groups (p-
value=0.045). The overall prevalence of migraine was 16.9% of the persons interviewed.
Conclusion: The results showed that migraine is more prevalent among obese persons than
non-obese persons and the difference was statistically significant.
