Gender differences in the prevalence and clinical correlates of sleep disturbance in general hospital outpatients

Sleep disturbance, which is characterized as having difficulty initiating or maintaining sleep or experiencing early-morning awakening (Cao et  al., 2017; Liu et al., 2000), appears to be one of a major public health concern with significant morbidities (Hou et al., 2017). Epidemiological surveys across different countries have reported a wide range of estimates of the prevalence of sleep disturbance, from 6% to 76.3% (Leger and Poursa in, 2005; Ohayon and Lemoine, 2002; Rocha et al., 2002; Xiang et al., 2008), reflecting both the variation between populations and differences in how sleep disturbance is measured.
