Abstract
Objective
To assess the impact of endometriosis of the posterior cul-de-sac on quality of sleep,
average daytime sleepiness and insomnia.
Study design
This age-matched case–control study was conducted in a tertiary referral centre for
the diagnosis and treatment of endometriosis between May 2012 and December 2013. It
included 145 women with endometriosis of the posterior cul-de-sac (cases; group E)
and 145 patients referred to our Institution because of routine gynaecologic consultations
(controls; group C). This study investigated whether sleep is impaired in patients
with endometriosis of the posterior cul-de-sac. Sleep quality, daytime sleepiness
and insomnia were assessed using the following self-administered questionnaires: the
Pittsburgh Sleep Quality Index, the Epworth sleepiness scale and the Insomnia Severity
Index, respectively. The primary objective of the study was to evaluate sleep quality
in the two study groups. Secondary outcomes of the study were to assess average daytime
sleepiness and insomnia in the two study groups.
Results
The prevalence of poor sleep quality was significantly higher in group E (64.8%) than
in group C (15.1%; p < 0.001). The prevalence of excessive daytime sleepiness was significantly higher in
group E (23.4%) than in group C (12.9%; p = 0.033). Patients of group E experienced subthreshold insomnia (29.0%) and moderate
clinical insomnia (16.6%) significantly more frequently than patients in group C (24.4%
and 5.0%; p = 0.002).
Conclusion
A substantial proportion of women with endometriosis of the posterior cul-de-sac experiences
poor sleep quality, excessive daytime sleepiness and insomnia.
