OBJECTIVE: Being born preterm is related to adverse health effects later in life. We studied whether preterm birth predicts the risk of migraine.
METHODS: In this nationwide register study, we linked data from six administrative registers for all 235,624 children live-born in Finland (January 1987 to September 1990) and recorded in the Finnish Medical Birth Register. n = 228,610 (97.0%) had adequate data and were included. Migraine served as primary outcome variable and was stringently defined as a diagnosis from specialised health care and/or ≥2 reimbursed purchases of triptans. We applied sex- and birth year-stratified Cox proportional hazard regression models to compute hazard ratios and confidence intervals (95% confidence intervals) for the association between preterm categories and migraine. The cohort was followed up until an average age of 25.1 years (range: 23.3-27.0).
RESULTS: Among individuals born extremely preterm (23-27 completed weeks of gestation), the adjusted hazard ratios for migraine was 0.55 (0.25-1.24) when compared with the full-term reference group (39-41 weeks). The corresponding adjusted hazard ratios and 95% confidence intervals for the other preterm categories were: Very preterm (28-31 weeks); 0.95 (0.68-1.31), moderately preterm (32-33 weeks); 0.96 (0.73-1.27), late preterm (34-36 weeks); 1.01 (0.91-1.11), early term (37-38 weeks); 0.98 (0.93-1.03), and post term (42 weeks); 0.98 (0.89-1.08). Migraine was predicted by parental migraine, lower socioeconomic position, maternal hypertensive disorder and maternal smoking during pregnancy.
CONCLUSION: We found no evidence for a higher risk of migraine among individuals born preterm.
