Short sleep duration and poor sleep quality among migraineurs: A population-based study

초록

Background Sleep disturbances are closely related to migraine. Nevertheless, information regarding the impact of short sleep duration and poor sleep quality on the clinical presentation of migraine at population level is limited. Methods This study was a nationwide population-based survey on adults aged 19-69 years. Headache frequency (attacks/month) and intensity (visual analogue scale, 0-10) were documented. Short sleep duration and poor sleep quality were defined as average sleep duration <6h/day and Pittsburgh Sleep Quality Index score>5, respectively. The association of sleep parameters with headache frequency and intensity was analysed among migraineurs. Results Of 2695 participants, 143 (5.3%) had migraine. Headache frequency was significantly higher among migraineurs with short sleep duration (2.0 [1.0-12.0] vs. 1.0 [0.3-4.0], p=0.048) and poor sleep quality (2.0 [0.6-4.7] vs. 1.0 [0.2-3.0], p=0.009) than among those without. However, headache intensity was similar between migraineurs with short sleep duration and poor sleep quality. Multiple linear regression analyses revealed that short sleep duration was a significant contributing factor for headache frequency (=0.210, p=0.015). Conclusions Self-reported short sleep duration (<6h per day) is associated with an increased headache frequency among migraineurs in a population-based setting.
