A new study published in the November/December 2012 issue of Headache suggests that nonmigraine headaches may be associated with low levels of vitamin D.
Marie Kjaergaard, MD, University Hospital of North Norway, Tromsø, Norway, and colleagues found that the incidence of non-migraine headache was 20% higher in those who had the lowest levels vitamin D than in those with the highest levels.
Other research has shown a high prevalence of headache in association with high latitude, which further support the relationship between headache and vitamin D.
For this study, participants were asked in a questionnaire whether they had experienced headache in the last year. If the answer was yes, they were asked to specify whether the headache was migraine or another type of headache, along with the average frequency, duration, intensity, and type. The data was adjusted to account for smokers.
The results showed significant increases in headaches regardless of a participant’s level of physical exercise, alcohol consumption, and educational level.
Investigators note that vitamin D levels reflect lifestyle and nutritional habits as well, both factors that can affect or be affected by headache.
