Kids from poorer families found to be at higher risk of migraine headaches, where there is not a family history of migraines.
In a unique study, researchers from the Texas A&M Health Science Center College of Medicine have linked income levels to migraines in kids. The results suggest environmental factors like stress and diet can be at the root of the severe headaches.
In the study, published in the July 3 issue of Neurology, a headache questionnaire was mailed to 120,000 households representative of the US population, and 18,714 adolescent subjects were identified for the study. Of this group, 1,178 adolescents had migraines, or 6.3 percent over the course of a year.
In families with income below $22,500 were about 50% more prevalent than in families with incomes of $90,000 or more. Migraines were also more prevalent in girls, and in Caucasians compared to African Americans.
Based upon the researchers conclude, “In adolescents with family history of migraine, household income does not have a significant effect, probably because of the higher biologic predisposition. In those without a strong predisposition, household income is associated with prevalence.”
The findings suggest that factors related to low incomes, such as, stress, poor diet, poor living environment, and limited access to medical care may contribute to migraines
