Because endometriosis is a complex condition that can negatively impact sleep, a recent study assessed the multifactorial variables associated with poorer quality of sleep in women with the disorder.
The study in the Journal of Women’s Health found that poorer overall quality of sleep was significantly associated with worse quality of life, more depression symptoms, and painful bladder syndrome (PBS).
“Sleep is important for chronic pain and for health in general,” said principal investigator Paul Yong, MD, PhD, an associate professor of ob/gyn at the University of British Columbia in Vancouver, Canada. “We wanted to further investigate the role of sleep in patients with endometriosis, a common cause of chronic pelvic pain.”
Data from the Endometriosis Pelvic Pain Interdisciplinary Cohort (EPPIC) data registry were analyzed for women with histopathological confirmation of endometriosis who underwent surgery at the BC Women's Center for Pelvic Pain and Endometriosis between June 2015 and June 2017.
A total of 275 women met the study criteria, of whom 86.5% had superficial endometriosis; however, 28.7% also had an ovarian endometrioma cyst and 18.5% had deep infiltrating endometriosis at the time of surgery.
The primary outcome was quality of sleep preoperatively, from the Chronic Pain Sleep Inventory (CPSI), based on a 0 to 100 standardized visual analogue scale (VAS), with 0 indicating the poorest quality of sleep and 100 the best quality of sleep.
