Prevalence and predictive factors for poor sleep quality among migraineurs in a tertiary hospital headache clinic.

The aim of this study was to investigate the prevalence and predictive factors for poor sleep quality among migraineurs in a tertiary hospital headache clinic in southwest China. In this study, we used a visual analog scale (VAS), the Pittsburgh Sleep Quality Index (PSQI), and the Hospital Anxiety and Depression Scale (HADS) to assess headache intensity, sleep quality as well as anxiety and depression symptoms. In 211 subjects who were assessed continuously, we found that the average PSQI score was 8.03 ± 4.71, and 130 (61.61 %) migraineurs exhibited poor sleep quality (PSQI >5). Poor sleep quality was largely expressed as experiencing an extended sleep latency period, daytime dysfunction, poor subjective sleep quality, and short sleep duration. The primary factors that predicted poor sleep quality included the migraine history and comorbidity with anxiety and/or depression. Moreover, we found that most migraineurs did not adopt treatment for their poor sleep quality. Only 17 (8.06 %) patients used sleeping medication to improve their poor sleep quality; however, this medication was not effective in 16 (94.12 %) patients. Therefore, it is highly important to resolve poor sleep quality in migraineurs.
