Preterm infants not at risk of developing migraine later: Study

Finland: The researchers in a recent study found no evidence that people who are born premature are at a higher risk of migraine later. However, according to the authors, the association between smoking during pregnancy and increased migraine risk warrants attention and further study. 

The study, published in the journal Cephalalgia, implies that preterm birth, across the entire gestational age range, was not a risk factor for subsequent migraine up until young adulthood.

Migraine is associated with risk of cardiovascular disease and stroke, psychiatric comorbidity, gestational hypertension, low socioeconomic position, and adverse pregnancy-related outcomes. These are the factors that have been tied to prematurity as well. Given that prematurity and migraine share a number of associated conditions and knowing that prematurity affects several aspects of neurological development, Sonja Strang-Karlsson, Finnish Institute for Health and Welfare, Helsinki, Finland, and colleagues set out to study whether preterm birth across the entire gestational age range, is associated with migraine in children or young adults in a nationwide register study.
