Data were collected from a cross-sectional, nationally representative set of 14,786 young adults in the United States aged 24-32 years who participated in the 2008 National Longitudinal Study of Adolescent to Adult Health, the investigators wrote in a research letter published in JAMA Neurology.
Food insecurity was assessed by self-report through the interview question, “In the past 12 months, was there a time when (you/your household were/was) worried whether food would run out before you would get money to buy more?” Migraine was assessed by a positive answer to the interview question, “Has a doctor, nurse, or other health care professional ever told you that you have or had migraine headaches?”
In all, 1,647 study participants (11%) reported food insecurity; the prevalence of migraine in this group was 23.9%, compared with a prevalence of 13.6% in participants who did not report food insecurity. The association between food insecurity and migraine was significant both before (odds ratio, 2.00; 95% confidence interval, 1.68-2.38; P less than .001) and after adjustment (adjusted OR, .58; 95% CI, 1.30-1.95; P less than .001).
“Health care clinicians caring for persons who experience migraine should consider screening for food insecurity as a potential contributor to migraine exacerbations and provide referrals to programs such as the Supplemental Nutrition Assistance Program [formerly the Food Stamp Program] when appropriate,” the investigators concluded (JAMA Neurol. 2019 Jun 24.).
