 We are interested in studying eating behaviours in children with migraine since there is evidence that altered patterns of eating behaviour and underlying changes in appetite are seen in migraineurs although not studied systematically. Altered appetite and eating behaviours may be a mechanism for the emerging association between obesity or degree of adiposity and migraine severity, detected in both adult and paediatric studies to varying extents. Studying the putative association between migraine, degree of adiposity and patterns of eating behaviour in children may help to tease out causal mechanisms, since both migraine and obesity often evolve over the course of childhood.
