We aimed to evaluate gender differences in the relationships between headache features, sleep quality, anxiety, depressive symptoms, and burden of headache in 193 patients (73 percent women) with chronic tension type headache (CTTH). Sleep quality was assessed with the Pittsburgh Sleep Quality Index. Headache features were collected with a four-week diary. ⋯ In women, positive correlations were observed between sleep quality and headache intensity (r = 0.282; p < .001), headache frequency (r = 0.195; p = .021), emotional burden (r = 0.249; p = .004), and depressive symptoms (r = 0.382; p < .001). The results of stepwise regression analyses revealed that depressive symptoms and emotional burden of headache explained 37.2 percent of the variance in sleep quality in men (p < .001), whereas depressive symptoms and headache intensity explained 17.4 percent of the variance in sleep quality in women (p < .001) with CTTH. Gender differences associated with poor sleep should be considered for proper management of individuals with CTTH.
