Objective: This nationwide population-based cohort study evaluated the effect of nonapnea sleep disorders (NSDs) on the subsequent development of a migraine.
Methods: We identified 46,777 patients aged 20 years and older who were diagnosed with an NSD (ICD-9-CM: 307.4 or 780.5) and without coding for apnea-sleep disorders (ICD-9-CM: 780.51, 780.53, or 780.57) between 2000 and 2002 as the sleep disorder (SD) cohort. A comparison cohort of 93,552 people was enrolled. We calculated the adjusted hazard ratio (aHR) for developing a migraine (ICD-9-CM: 346) after adjusting for age, sex, comorbidity, and drug use. A Kaplan-Meier analysis was used to measure the cumulative incidence of a migraine between 2 curves until the end of 2011.
Results: The cumulative incidence of a migraine was significantly higher in the SD cohort. The aHR for developing a migraine in the SD cohort was 3.52 (95% CI = 3.28-3.79). The risk of developing a migraine with an NSD was higher in men (aHR = 4.31) than in women (aHR = 3.35). The age-stratified effect of an NSD on developing a migraine was highest among patients aged 55 years and younger. Higher risks of developing a migraine were observed among the participants without any comorbidity and without any drug treatment for their insomnia.
Conclusion: The findings of this population-based cohort study indicate a higher risk of developing a subsequent migraine in patients with an NSD, which could be considered an independent, predisposing factor for developing subsequent a migraine in adulthood.
