Summary

Body mass index (BMI) does not affect migraine prevalence but significantly increases headache attack frequency and severity. Higher BMI categories correlate with more frequent and intense migraine attacks, including pain, disability, photophobia, and phonophobia.

Area of Science:

  • Neurology
  • Public Health
  • Epidemiology

Background:

  • Migraine is a common neurological disorder with significant public health implications.
  • The relationship between body mass index (BMI) and migraine characteristics requires further investigation.

Purpose of the Study:

  • To determine the influence of body mass index (BMI) on migraine prevalence.
  • To assess the association between BMI and migraine attack frequency, severity, and clinical features.

Main Methods:

  • A population-based telephone interview study involving 30,215 participants.
  • Participants were categorized into five BMI groups: underweight, normal weight, overweight, obese, and morbidly obese.
  • Migraine prevalence and headache features were analyzed as a function of BMI, adjusting for covariates.

Main Results:

  • BMI was not associated with migraine prevalence.
  • Headache attack frequency significantly increased with higher BMI categories (e.g., morbidly obese: OR=5.7).
  • Migraine severity, disability, photophobia, and phonophobia also increased with rising BMI.

Conclusions:

  • Body mass index (BMI) is not linked to the prevalence of migraine.
  • Higher BMI is associated with increased frequency, severity, and specific clinical features of migraine attacks.
