Is Headache Related to Asthma Hay Fever, and
Chronic Bronchitis? The Head-HUNT Study

Posted: April 2007
Objectives: To examine the relationship between migraine and
nonmigrainous headache and asthma, hay fever, and chronic bronchitis in a large cross-sectional
Background: Associations between prevalence of migraine and asthma or allergy
have been demonstrated in clinic-based and epidemiologic studies whereas studies on chronic
bronchitis are scarce.
Methods: A total of 51,383 subjects completed a headache questionnaire and
constituted the "Head-HUNT" Study. Of these, 50,401 answered the questions about asthma and
chronic bronchitis, and 47,029 answered the question about hay fever.
Results: Both migraine and nonmigrainous headache were approximately 1.5 times
more likely among those with current asthma, asthma related symptoms, hay fever, and chronic
bronchitis than those without. The association increased with increasing headache frequency.
Conclusions: This large questionnaire-based study confirms that migraine and
other headaches are associated with respiratory and allergic disorders. The magnitude of the
association between headache and asthma, hay fever, and chronic bronchitis tended to be in
the same order. Headache frequency seems to have a greater impact on the association with
respiratory or allergic conditions than headache diagnoses. Whether it is a causal
relationship is uncertain, but the results underline the importance of considering comorbid
disorders among patients with frequent headache.
