A study found a higher prevalence of self-reported migraine in young adults who also report frequent food insecurity. Findings from this study were published in JAMA Neurology.
Cross-sectional data from the fourth wave (2008) of the National Longitudinal Study of Adolescent to Adult Health were used to obtain self-reported data of US young adults aged 24 to 32 years. Food insecurity was identified by a self-reported response to a question regarding food shortage in the home within the past 12 months. According to the researchers, the question had a 93% sensitivity and 85% specificity. Migraine was also identified by a self-reported answer to an interview question that asked whether the patient had ever had a doctor, nurse, or other clinician provide the patient a verbal diagnosis of migraine headaches.
Based on the responses to the food security questions, a total of 13,139 of the fourth-wave population reported food security (mean age, 28.3 years) vs 1647 who reported food insecurity (mean age, 28.4 years). Food insecurity was reported more frequently among individuals with a greater mean household size (2.5 vs 2.1; P <.001), those who smoked (46.3 vs 28.1; P <.001), and those who recently used public assistance (53.5 vs 20.7; P <.001).
Individuals who reported food insecurity had a higher self-reported prevalence of migraine than young adults who reported food security (23.9% vs 13.6%, respectively; P <.001). Greater odds of migraine were also found in young adults who reported food insecurity in the unadjusted analysis (odds ratio, 2.00; 95% CI, 1.68-2.38; P <.001) and adjusted analysis (adjusted odds ratio, 1.58; 95% CI, 1.30-1.95; P <.001).
Limitations of the study include its retrospective design and the reliance on self-reports for migraine identification.
Based on their findings, the investigators of the study suggest that “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.”
