Painful bladder syndrome (PBS) is frequently associated with deep endometriosis (DE), and both conditions cause chronic pelvic pain (CPP), which often impairs sleep quality. This study was aimed at analyzing the impact of CPP plus PBS in women with DE on the global sleep quality index using the Pittsburgh Sleep Quality Index (PSQI) and subsequently examine each sleep dimension.
One hundred and forty women with DE were included and answered the PSQI and the O'Leary-Sant Interstitial Cystitis Symptoms and Problem Index questionnaires with or without CPP. Women were categorized into good or poor sleepers using the PSQI cutoff; subsequently, a linear regression model was used to analyze the PSQI score and a logistic regression model for each questionnaire's sleep component.
Only 13% of women with DE had a good sleep. Approximately 20% of those with DE but no/mild pain were good sleepers; 138 women with DE (88.5%), 94% with PBS, and 90.5% with moderate/severe pain were poor sleepers. For PSQI components, CPP worsened the subjective sleep quality by more than threefold (p = 0.019), increased sleep disturbances by nearly sixfold (p = 0.03), and decreased the sleep duration by practically sevenfold (p = 0.019). Furthermore, PBS increased sleep disturbances by nearly fivefold (p < 0.01).
The addition of PBS to CPP in women with DE is devastating for overall sleep quality, probably because it impacts some sleep dimensions unaffected by CPP and amplifies the problem in those already affected by pain.
