Sexual dysfunction in peritoneal dialysis patients

Am J Nephrol. 2007;27(6):615-21. doi: 10.1159/000108357. Epub 2007 Sep 11.


Background/aims: Sexual dysfunction in patients undergoing peritoneal dialysis (PD) is highly prevalent, but studies addressing this issue are scarce. This cross-sectional study aims to evaluate sexual dysfunction and the determinants among PD patients.

Methods: All chronic PD patients in 8 PD centers were asked to complete a self-reported questionnaire - the International Index of Erectile Function (IIEF) for men and the Index of Female Sexual Function (IFSF) for women - so that sexual function could be assessed. They also answered the Beck Depression Inventory (BDI) to measure depressive symptoms.

Results: Among 294 patients invited for study, 54 men (mean age 48.8 +/- 10.8 years) and 45 women (mean age 43.6 +/- 7.4 years) were willing to and completed the sexual function questionnaires. The median IIEF score in the men was 56.25. The prevalence of erectile dysfunction, identified by the score in erectile domain of IIEF <or=25, was 51.9%. Older age and higher fasting glucose levels were independently associated with a decreased IIEF score. In women, IFSF score (with a median 27) was significant lower than in healthy peri- or postmenopausal control women. Factors of higher BDI score, receiving automated PD, and older age independently associated with a decreased IFSF score.

Conclusions: Sexual dysfunction is clinically relevant and multi-dimensional among PD patients. Gender differences exist in the attributing factors of sexual functioning. These warrant more awareness and investigation in the global health care of dialysis patients.
